Abstract:
This paper examines relative stock market performance following the onset of the coron-
avirus pandemic for a sample of 80 stock markets. Weekly data on coronavirus cases and deaths are
employed alongside Oxford indices on each nation’s stringency and government support intensity.
The results are broken down both by month and by geographical region. The full sample results show
that increased coronavirus cases exert the expected overall effect of worsening relative stock market
performance, but with little consistent impact of rising deaths. There is some evidence of significantly
negative stock market effects arising from lockdowns as reflected in the Oxford stringency index.
There are also positive reactions to government support in March and December in the overall
sample—combined with some additional pervasive effects seen in mid-2020 in Latin America.

I can’t abandon that [lockdown] tool any more than I would abandon a nuclear
deterrent. But it is like a nuclear deterrent, I certainly don’t want to use it.
(British Prime Minister Boris Johnson, 19 July 2020—as quoted in Malnick 2020)
Speculative manias are in the air
. . .
Along with the other economic trends—a
strong recovery, surging commodity prices and an uptick in inflation—those
asset bubbles have a clear cause: the massive expansion of money and credit.

1. Introduction
The coronavirus pandemic of 2020 represented the most devastating health crisis since
the Spanish Flu of 1918–1919. Although stock markets reacted negatively to the spike in
death rates at that time (Burdekin 2021), far more violent moves were seen in 2020. The
record-breaking 33.7% drop in the S&P 500 stock market index between 19 February and
23 March 2020 was accompanied by massive declines in most other major stock markets
around the world. This was quickly followed by record GDP declines in the second quarter
of 2020 in the United States and many European countries. Nevertheless, most of these
same countries then enjoyed a major stock market boom from the March lows in the face of
massive central bank liquidity expansion (Burdekin 2020a).1
The initial US stock market plunge following the onset of the 2020 pandemic greatly
outpaced the earlier experience under the Spanish Flu. Even though the Spanish Flu
appears to have been far deadlier (cf. Burdekin 2020b), the US stock market initially
continued to rise following the outbreak in late 1918 and merely fell back to summer 1918
levels after monthly deaths peaked later in the year. There was a sharp rebound afterwards,
however, and the Dow Jones Industrial Average gained around 50% from late February
1919 through the end of the year. Pent-up demand following the end of the pandemic
may well have been a factor in this outcome (Burdekin 2020a)—as could prove to be true
once again in 2021. Nevertheless, a major difference between the 1918–1919 and 2020–2021

experiences remains the far lesser extent of the lockdowns and government intervention
seen during the earlier episode.2
The main goal of this paper is to assess US stock market behavior not in isolation
but in comparison with relative performance in other world stock markets. Additionally,
in contrast to most prior empirical work, the analysis extends beyond the initial crisis
period up until the final trades of December 2020. Following the next section’s discussion
of the existing literature on stock market responses to the pandemic, Section 3outlines
the paper’s methodology. The data used to explain relative stock market performance on
the basis of virus spread and government intervention are also detailed there. The main
findings for our 80-country study are then presented in Section 4. Finally, Section 5contains
the paper’s conclusions.
2. Explaining the 2020 Stock Market Reactions
The enormous market turnaround after March 2020 occurred despite accelerating
coronavirus spread around the world, with cases rising in every continent besides Antarc-
tica. Cox et al. (2020, p. 20) conclude that the stock market rebound was largely driven by
shifts in sentiment rather than fundamentals: “We find that the most likely candidate for
explaining the market’s volatility during the early months of the pandemic is the pricing
of stock market risk, driven by big fluctuations in risk aversion or sentiment unrelated to
economic fundamentals or interest rates.” The rise in market volatility actually appears to
precede the March shutdowns and travel bans, with Just and Echaust (2020), for example,
identifying a shift from a low volatility regime to a high volatility regime in late February
2020.
3
Alber (2020) and Ashraf (2020) seek to quantify stock market responses to rising
virus cases and deaths early in the pandemic across as many as 64 countries. Although
they each identify a more significant role for cases than deaths, Al-Awadhi et al. (2020)
find both of these variables significant in China over a 10 January—16 March 2020 sample
period. Panel data analysis by Khan et al. (2020), using weekly data through the end of
March 2020, confirms significant effects of coronavirus cases across sixteen stock markets.
4
Although the pandemic continued to play a key role, the extreme shifts seen early on
in the pandemic were not typical of the later experience. Indeed, Phan and Narayan (2020)
find support for a possible initial stock market over-reaction to the coronavirus that was
already evident in data going through just early April 2020. This reflects Phan and Narayan
(2020) finding that initial negative reactions to new cases and deaths are often followed by
positive responses later on, with half of the 25 stock markets seemingly evincing positive
reactions after reaching 100,000 cases and 100 virus-related deaths. A case in point is the
remarkable US market rally from the March 2020 lows even as virus cases and deaths
continued to ratchet higher through the end of the year. Meanwhile, whereas contagion
between markets appeared to soar with the onset of the pandemic, Okorie and Lin (2021)
find that this initial shock effect was already fading away by the end of March 2020.
5
This
only points to the importance of considering data extending beyond the initial crisis period.
In addition to the spread of the virus itself, other factors coming into play over time
include government reactions to the public health emergency, such as the massive stimulus
measures undertaken in the United States and Europe to provide economic support to
individuals and businesses. The positive stock market effects themselves appear to have
been far from uniform, with Harjoto et al. (2021) finding the beneficial effects to have been
concentrated on larger firms.
6
These government spending initiatives were accompanied
by widespread monetary easing, which, in the US case, resulted in annual M2 money
supply growth of 28% after February 2020. This was far greater than during the global
financial crisis, and the highest rate of money emission seen since 1943 at the height
of World War II (Greenwood and Hanke 2021).
7
Australia was just one of many other
countries embarking on similarly unprecedented stimulus efforts. Nevertheless, Rahman
et al. (2021) find evidence of quite mixed stock market reactions with only the “JobKeeper”
package (announced on 22 March 2020) eliciting a clearly significant, favorable stock market
reaction.
J. Risk Financial Manag. 2021,14, 177 3 of 18
Shifts in the level of economic support in either direction could be expected to trigger
stock market reactions, with Chan-Lau and Zhao (2020), for example, emphasizing negative
stock market reactions in cases where government stimulus was withdrawn when the
number of daily COVID-19 cases remained relatively high. There is also the impact of
government-ordered lockdowns, however, and Baker et al. (2020) conclude that it was
these government restrictions on commercial activity, combined with social distancing,
that account for the US stock market reacting so much more forcefully to COVID-19 than to
the Spanish Flu (or prior pandemics). Given that stock markets would be expected to react
to both stimulus measures and lockdowns, this paper provides new comparative evidence
on the impact of each assessed over a broad range of world stock markets. The effects of
rising coronavirus cases and deaths are also controlled for in the analysis.
We compare relative market performance to each country’s relative levels of virus
cases, virus deaths, government stringency and economic support. We examine these
relationships not only in the aggregate but also on a continent-by-continent basis for
each month between March and December 2020. This encompasses the span between
the extreme pessimism evident in market reactions early in the pandemic to the greater
optimism emerging later on, spurred also by encouraging vaccine news in November and
December 2020. Following the release of favorable clinical trials data in November 2020,
the Pfizer COVID-19 vaccine was approved for emergency use in the United Kingdom on
2 December and in the United States on December 12.
3. Methodology and Properties of the Data
This paper sets virus effects on stock market performance against the relative impor-
tance of government interventions. Whereas most prior work was limited to data through
just the first quarter of 2020, this combination of factors is assessed over a sample period
extended from March 2020 through the end of the year.
8
Like Khan et al. (2020), we utilize
weekly data and employ pooled OLS (ordinary least squares) analysis. In order to allow
for varying relationships over the year, panel regression analysis is applied not only for the
full sample and also for the individual months between March 2020 and December 2020.
In order to make the analysis as broad-based as possible, we incorporate 80 stock market
indices drawn from all corners of the globe (Appendix ATable A1). Our focus is on the
relative strength of each market during 2020 and we essentially include every available
stock market, with just Venezuela and Zimbabwe excluded owing to the distortions associ-
ated with their respective hyperinflations that predated the pandemic. The stock market
data are drawn from the Bloomberg terminal (with the exception only of the Jamaican
market index, which is directly downloaded from the Jamaica Stock Exchange website at
www.jamstockex.com, accessed on 10 April 2021).
The paper’s panel estimation assesses how each market’s relative strength is affected
by variations in virus conditions and government measures. We utilize publicly available
data on coronavirus virus and deaths, in each case scaled by population in order to
achieve comparability across countries. The government policy responses are quantified
on the basis of the data series available in Oxford University’s “Coronavirus Government
Response Tracker” (Hale et al. 2020). The Oxford University data utilizes an ordinal
scale reflecting the relative level of economic support and the relative level of stringency.
Economic support encompasses income support, debt/contract relief for households, fiscal
measures, and provision of international support. Meanwhile, the stringency index collates
publicly available information on such policies as school and workplace closures, stay at
home restrictions and travel bans to produce an additive score measured on an ordinal
scale that varies from 0 to 100 (see Appendix ATable A2).
We regress each stock market’s relative strength index (market_RSI) on (i) increases in
cases per 100,000 (g_cases100k), (ii) increases in deaths per 100,000 (g_deaths100k), and
(iii) the Oxford series on the levels of government economic support (econsupport) and
stringency measures (stringency). A lagged dependent variable and lagged cases and
deaths are also included to allow for inertia. Increases in cases and deaths are used instead
J. Risk Financial Manag. 2021,14, 177 4 of 18
of cumulative cases and deaths owing to the non-stationarity of the latter series, which
continuously rise over the sample period. Although cases and deaths are themselves both
manifestations of the same virus spread, the timing of the two series is quite different.
Testa et al. (2020), for example, show deaths typically not occurring until between two
weeks and eight weeks after the onset of symptoms. Each of the Oxford series is measured
on a scale of 0–100, with zero being lowest and 100 representing maximum intensity. The
market_RSI puts each stock market on a scale from 1 to 80, with 1 being the top performer
and 80 being the bottom performer. Relative strength is assessed on the basis of the dollar
returns for each market index.9
In addition to the fluctuations in virus infections and policy responses over time,
Table 1reveals substantial geographical variation in 2020. Summary statistics over the
March-December 2020 period for the full sample of 80 countries (Table 1a) are followed by

The geographical groupings are primarily done by continent, but with Asia and Europe
divided into two parts. In the case of Europe, the separation is between the more established
nations of Western Europe and the primarily emerging economies of Eastern and Southern
Europe. Although East Asia covers a range of development levels, all these nations share
relative proximity with China and most are members of ASEAN (Association of Southeast
J. Risk Financial Manag. 2021,14, 177 6 of 18
Asian Nations). The countries in the South Asia and Middle East group are distinct both in
terms of geographical location and by typically having lesser links with China.
The summary data broken down by region in Table 1b–i show some of the enormous
variations in national experiences under the pandemic. For example, North America
(Canada and United States) show an average 72.9 increase in cases per hundred thousand
and 1.40 deaths per hundred thousand. Even with all these numbers scaled by population,
the North America figures are over fifty times greater than the corresponding Australasia
values. Cases and deaths in Africa and East Asia are also dramatically lower than in North
America, while the other regions represent intermediate cases—but generally closer to the
North American levels than Africa, Australasia, and East Asia.
The highest average levels of stringency are seen in Latin America, South Asia and
Middle East, North America, and East Asia (in that order). The other regions are all
below 50 on a scale of 0–100, with Australasia having the lowest average value of all.
However, it should be emphasized that even Australia’s average stringency level of 44.6 is
substantial, leaving it within 25% of the highest level of 59.0 registered in Latin America.
Interestingly, despite having the lowest virus cases, virus deaths and average stringency
levels, Australasia has the highest average level of government economic support (60.1).
Western Europe is just behind with 59.4, followed by North America with 59.3 and Eastern
and Southern Europe with 59.0. The nations of Africa and Latin America on average offered
the least economic support, with index values of 37.9 and 41.6, respectively.
4. Empirical Findings
The panel estimation results have the relative strength of each market index is re-
gressed on its own lagged value, current and lagged levels of additional cases (per hundred
thousand of the population), current and lagged values of additional deaths (per hundred
thousand of the population) and that country’s Oxford index values for stringency and
economic support. As noted earlier, weekly data are employed in the regressions and the
results are broken down both by month and by geographical region.
10
Given that stronger
market performance equates to a lower market_RSI value, the expected signs on virus
cases and virus deaths is positive insofar as worse virus spread exerts a negative market
effect. The expected sign on stringency would also be positive given that negative effects on
economic activity should worsen the relative performance of the stock market. Finally, the
expected sign on econsupport would be negative if the additional funding boosts relative
market performance.
The full sample results in Table 2show increased cases to exert the expected overall
effect of worsening relative stock market performance. This effect is significant at the 95%
confidence level or better overall as well as for April, August and October individually.
Although there is some evidence of an offsetting effect of lagged cases, this may simply
reflect the market impact of a rise in cases subsiding over the following month. New
deaths are insignificant overall, but are significant and positive in May and August (while
significant and negative in April and September). Such variation over the sample is
unsurprising insofar as Phan and Narayan (2020) noted swings from negative to positive
effects even in a study limited to the early months of the pandemic alone. There are
similarly mixed findings for lagged deaths and no clear systematic effect.

Stringency and econsupport are insignificant overall. This may reflect, in part, mea-
surement error in the available Oxford indices, which would, in turn, bias down the
estimated coefficients. Although stringency has the expected positive and significant effect
in March and July, the significant negative effect for September suggests a favorable impact
on relative market strength later in the year. Meanwhile, econsupport is significant with
the expected negative sign in March and December, but significant with the opposite sign
in May. With the major first and second waves of the virus in countries like the United
States occurring in or around those same March and December months, it may well be that
government support was seen as being more critical at those times; this could explain why
there appear to be favorable market reactions in those particular months.
Appendix BTables A4A9 present results for the individual geographical groupings.
Although Australasia and North America were included in the full sample results reported
in Table 2, the number of countries in these two groups is insufficient for separate regression
analysis. In terms of the overall findings across the different groupings, increased cases are
significant with the expected positive sign for East Asia and Western Europe. Increased
J. Risk Financial Manag. 2021,14, 177 8 of 18
cases are insignificant overall in all other regions, with mixed significance observed in
individual months. New deaths are significant overall only for Western Europe, with a
negative sign. This counterintuitive finding seems to primarily derive from a strong effect
indicated for July, when deaths were generally trending down, and may simply reflect a
failure of markets to recover when the death rate improved. Elsewhere, there are generally
very mixed findings across individual months that leaves little clear pattern. However,
Africa has four months (March, April, September and December) for which deaths exert
significant positive effects, i.e., weakening stock market RSI.
Stringency is significant overall with the expected positive (weakening RSI) effect
only for Africa. Although it is otherwise significant overall just for East Asia, and with
a negative sign, in terms of individual months it is significant there with the expected
positive sign in March and only significant with a negative sign in September. In Eastern
and Southern Europe as well as Latin America, stringency is significant with the expected
positive sign in June and insignificant for other months. South Asia and Middle East also
evinces a significant positive effect of stringency in June, but with offsetting indicated
significant negative effects in May and September. Although the findings remain quite
mixed, there is a tendency for stringency measures to hurt stock market performance earlier
in the pandemic (as seen for March and June 2020).
Finally, economic support is never significant overall and the only clear case of benefi-
cial stock market effects is seen for Latin America. In this region, econsupport is negative
and significant in each of May, June and August (while positive and significant in July). In-
cluded here is the Brazilian support package of as much as USD 10 billion per month, more
than for any other developing nation, that helped Brazil’s GDP exceed its pre-pandemic
January 2020 levels by July—albeit it at the expense of potentially disastrous longer-term
fiscal consequences (see Magalhaes and Pearson 2020). The lack of more consistent overall
findings for economic support may reflect the fact that such support is usually applied
when times are darkest. If the such support is applied in the face of an already weakening
market, it will only appear successful on a statistical basis if it is able to immediately turn
this trend around. This will not always be the case, even if these same interventions do
help lay the groundwork for subsequent recovery.
5. Conclusions
Whereas the existing literature on the stock market effects of the pandemic has pri-
marily focused on just the early crisis period in the first quarter of 2020, this paper assesses
virus effects and government policy effects through December 2020 for a broad sample of
80 world stock markets. The overall results offer some support for growth in coronavirus
cases and stringency hurting stock market performance, together with some evidence
that 2020 government support measures helped the market both in March and late in the
year. However, there is considerable variation across the different geographical regions
considered in this paper. Clear-cut adverse effects of new coronavirus cases are found only
for East Asia and Western Europe, for example. There is more widespread evidence of
adverse effects associated with stringency, in overall terms for Africa and during mid-year
in Eastern and Southern Europe, Latin America and South Asia and Middle East. Economic
support’s favorable effects in March and December in the overall sample are generally not
mirrored over the different geographical groupings. However, there are several significant
months for the Latin American grouping around mid-2020.
The empirical findings are limited both by the total coverage being only ten months
and the impossibility of fully capturing the tumultuous events through the limited array
of variables included in the regressions. Nevertheless, markets are seen to generally
react to growth in cases in the expected fashion and there is some relatively widespread
evidence of adverse stringency effects on relative stock market performance. Although it
is possible that positive reactions to government support in March and December in the
overall sample may be driven by the US experience, there are also some pervasive effects
in mid-2020 evident elsewhere—especially in Latin America. More generally, it is clear
J. Risk Financial Manag. 2021,14, 177 9 of 18
that the substantial variation by region would make it unwise to draw too many general
conclusions from analysis focused more narrowly on either the United States alone or just
more advanced industrial countries. It is hoped that the wide-ranging sample covered in
this study can serve as a starting point in unpacking what has driven market performance
globally under the coronavirus pandemic. A similarly broad-based approach might be
employed in assessing the impact of the vaccine rollout in 2021, which began much more
rapidly in countries like Israel, the United Kingdom and the United States than in most of
the rest of the world.

Notes
1
This is itself consistent with the past experiences considered by Friedman (2005), who links the US stock market
recovery from the post-1999 crash to rapid Federal Reserve monetary expansion and contrasts this with the effects of
stagnant money supply in post-1989 Japan and monetary contraction in the post-1929 US case. Meanwhile, as with
the late 1990s Nasdaq bubble, the effects of US monetary expansion in 2020–2021 may well have been channeled
primarily into the stock market (whereas goods prices remained subdued).
2
An especially telling fact is Velde (2020) observation that, by the January 1919 issue of the Federal Reserve Bulletin,
the Spanish Flu pandemic was no longer meriting even a mention in the Federal Reserve’s main publication. The
contrast with the aftermath of the coronavirus pandemic in 2021 could not be more stark.
3
The onset of such high volatility regimes can itself produce significant sectoral effects, as seen in Burdekin and Tao’s
(2021) comparative Markov-switching analysis of gold’s hedging value in 2020 vs. 2008–2009.
4
A further factor considered by Ashraf (2021) is the potential for stronger virus-related stock market effects in countries
with higher uncertainty avoidance (as proxied by survey data from employees and middle-managers of sampled
firms).
J. Risk Financial Manag. 2021,14, 177 17 of 18
5
Similarly, whereas contagion often emerged during past European crises, Bo¸toc and Anton (2020) find that this
typically proved to to be a short-lived phenomenon and was not necessarily indicative of greater longer-run
cointegration.
6
Further evidence on the differential stock market reactions around this time is provided by Mazur et al. (2021), who,
not surprisingly, find widespread sectoral variations.
7
Not only does experience from past pandemics suggest considerable risks of post-pandemic inflation owing to
pent-up consumer demand (Burdekin 2020a), but also such dangers have likely been greatly understated by Modern
Monetary Theory proponents (Bird et al. 2021).
8Few countries outside of China exhibited meaningful virus case numbers and deaths prior to March.
9
Dollar returns, rather than returns in local currency, allows for more of an apples-to-apples comparison as the gains
in value of a dollar invested in the US market are set against the gains realized from that same dollar invested abroad.
10
Stationarity of the variables entered in the regressions is confirmed by application of the Harris and Tzavalis (1999)
unit root test. This test is appliable to cases where the number of panels is large relative to the number of time
periods. The results reject the presence of a unit root at better than the 98% confidence level or better in each case
(Appendix ATable A3).

... Third, regarding the link between variables, especially for extreme events, the quantile-varying estimates show that ordinary least square methods provide an incomplete picture. While throughout the asset return distributions, quantile regression is more suitable in handling the extreme values and fat tails problems (Du Table 1 Hypotheses with expected signs and source Reproduction rate H3 Negative ( −) (Burdekin & Harrison, 2021;Díaz et al., 2022) New tests H4 Positive ( +) (Anser et al., 2021) Positive rate H5 Negative ( −) (Chatjuthamard et al., 2021;Xu, 2021) Stringency index H6 Negative ( −) (Alexakis et al., 2021;Burdekin & Harrison, 2021;Raifu et al., 2021) Extreme poverty index H7 Negative ( −) (Umar & Nayan, 2018) Life expectancy index H8 Positive ( +) (Umar & Nayan, 2018) Human development index H9 Positive ( +) (Forti et al., 2011;Ranis et al., 2000) Barnes and Hughes (2002) argued that quantile regression also mitigates the problem of non-Gaussian error distribution and sensitivity to outliers. Moreover, most of the developed markets show asymmetric dependencies in COVID-19-related information (Cepoi, 2020). ...

This study aims to examine the influence of the COVID-19 outbreak on daily market returns in most affected developed and emerging markets. For this purpose, panel data of 30 most affected developed and emerging markets over the period Jan-uary 1, 2020, to December 12, 2020, were analyzed by using panel estimated generalized least square (panel-EGLS) and panel quantile regression approaches. The results confirm that the new COVID-19 daily cases and deaths adversely impact daily market returns around the globe. Also, the positive rate of new COVID-19 cases has also negatively influenced market returns. Further, the number of new COVID-19 daily tests conducted has a positive impact on market returns. Interestingly , the study also found similar impacts for both developed and emerging markets except the news announcement of new COVID-19 daily deaths, which have a positive impact on emerging market returns. The findings of this study present some policy implications for governments to adopt early proactive and control measures to protect financial markets from an adverse decline in future pandemics and to increase investors' confidence.
... Adenomon and Idowu (2022) argued that pandemic determined significant breakdown the case of most economies based on the dynamics of Gross Domestic Product also known as GDP, but the financial markets were also massively affected. Burdekin and Harrison (2021) considered that the COVID-19 pandemic constitutes the most severe health crisis since the previous Spanish Flu of 1918-1919 revealed the effect of COVID-19 pandemic on stock markets due to a severe distress based on unpredictable uncertainty. Tarczyński et al. (2021) discussed the classical finance theory approach which is based on the assumption that all market participants are rational focused on profit maximization which refers to the high efficiency of the stock market. ...

The main aim of this research paper is to estimate volatility patterns using GARCH models based on a case study on Swedish stock market. The selected time period covers the long time interval from December 2008 to December 2022. In other words, the analyzed period includes certain extreme events such as global financial crisis of 2008 and COVID-19 pandemic which had a significant impact on most stock markets in Europe. The econometric framework includes GARCH family models. This empirical research study contributes to the existing literature on the behavior of the developed stock market from Sweden.
... It can be observed that apart from post-event day 14 AAR on the continent, the impact of COVID-19 infections on the Africa market exacerbated post-event day. This result is in tandem with Burdekin and Harrison (2021), Chowdhury et al. (2021) and Shaikh (2020), who observed serious negative impacts of the COVID-19 pandemic on global stock markets. The worsening AARs for the continent post-event day could be attributed to the lack of confidence by investors in the ability of Africa to handle the surging COVID-19 cases due to the weak health care systems on the continent. ...
... По време на първите няколко месеца от пандемията, не бяха ясни ефектите върху финансовата стабилност дължащи се на промените в поведението на населението и на държавните рестрикции върху производствените вериги. Рекордният спад на борсовият индекс S&P 500 в САЩ между 19 февруари 2020 г. и 2 март 2020 г. (както и на повечето други борсови индекси по света) бе водещи индикатор за рекордните спадове на БВП през второто тримесечие на 2020 г. в САЩ и повечето европейски държави (Burdekin and Harrison, 2021). Една от особеностите на пандемията е, че тя довежда едновременно до макроикономически шокове на търсенето и макроикономически шокове на предлагането. ...

The study employs the market model and event study approach with four events to examine the performance of the African stock market amid COVID-19 global health crisis. We use daily stock market data from 14 African countries (as a proxy for the African market) spanning September 2019 to June 2021 and COVID-19 data to estimate average abnormal returns for Africa. The results show significant positive average abnormal returns in Africa when the WHO announced COVID-19 as a global health epidemic. The events of infections and deaths generated significant negative average abnormal returns while the event of vaccination did not generate any significant average abnormal returns in the market. In as much as pandemics are unpredictable, the African market quickly recovers as depicted by COVID-19; therefore, we recommend to investors, speculators, and portfolio managers not to quickly exit the continent during pandemics. Keywords: COVID-19; Africa; stock market; performance; event study; market model; abnormal returns.

In the present work, a study has been made over the prime stock indices of some fiscally prominent countries impacted by COVID-19. The countries are separated in two ways: (1) considering gross total number of infected cases—here seven mostly impacted countries with certain global economic influence are selected; (2) considering the concentration of the infected cases—here six major impacted countries with considerable influence are selected. This sort of categorization is itself a novel strategy which is capable of including some less populated, but severely impacted countries of economic importance. The objective of the present analysis is to comprehend the impact of COVID-19 on these markets and to recognize the effect of COVID-19 on mutual association and dependence between these markets. To add more flavour of reliability, we have taken a new and fresh strategy of fixing the time frames under consideration before and during COVID-19 pandemic as uniform. We have used both linear and nonlinear Granger causality analysis and employed generalized forecast error variance decomposition analysis to review the exogeneity and endogeneity of the individual markets. The present study shows that this pandemic has changed the underlying relationship: some exogenous stock markets have become endogenous and vice versa in the pandemic. Linear relationship has been reduced radically, whereas nonlinear relationship has been improved during the COVID-affected period. TASE, the highest returned and significantly uncorrelated index, emerged as the most exogenous market in the pre-COVID period, though it is nonlinearly endogenous in the long term, in the COVD-affected period. CAC 40 is the most endogenous market for the short term in both pre-COVID and COVID-affected period. B3 and NYSE, exogenous in the pre-COVID period, turned out to be linearly endogenous in the COVID-affected duration, whereas BIST 100 and BSE SENSEX are found to be exogenous markets in the COVID-affected period according to both linear and nonlinear causal analysis. They were also exogenous in the pre-COVID era for the short-term period, with BSE SENSEX exhibiting exogeneity anti-persistently for the COVID-affected period too. Association among the markets is more in long term rather than short term. A possible conclusion is also that the markets may regain long-term association once the effect of COVID would fade away.

This study examines the effects of the various COVID-19 announcements by the World Health Organization (WHO) on stock returns in ASEAN countries, which is different from previous research in that most of the research only observed the first announcement of COVID-19 when a pandemic was declared This study uses 6 announcements of COVID-19, starting from the first time COVID-19 was identified until it was declared a variant delta. The results revealed that the market reaction in ASEAN to the first announcement of COVID-19 in China on December 31st, 2019, shows a positive and non-significant abnormal return and cumulative abnormal return. On January 13th, 15th, 21st, and 24th, 2020, the market also reacted negatively but not significantly to the announcement of the first recorded case outside China, which is in Thailand, Japan, the USA, and the European region, and it was an intermittently negative reaction but not significant. On March 7th, 2020, when the confirmed cases surpassed 100,000 globally, and on March 11th, 2020, when WHO officially announced COVID-19 as a global pandemic, the ASEAN market reacted negatively and significantly for abnormal and cumulative abnormal returns, which is inconsistent with Salisu, Sikiru and Vo (2020) and Topcu and Gulal (2020). However, the ASEAN countries reacted positively but not significantly to the second wave announcement on May 31st, 2021.

This study investigates the impacts of pandemic‐induced economic policy uncertainties (PIEPU) on the S&P500, Nasdaq‐100, and Dow Jones indexes (stock returns). To this aim, for the first time, newly created IDEMV (the Infectious Disease Equity Market Volatility index (henceforth, PIEPU index) is used. The Autoregressive Distributed Lag (ARDL) model and the Toda and Yamamoto (Journal of Econometrics, 1995, 66, pp. 225–250) causality test are applied for the 2009–2020 period. Empirical findings indicate that rises in the PIEPU index lead to falls of only the S&P500 and Dow Jones indexes. Corporations in the tech‐heavy Nasdaq100 index do not negatively respond to rises in the PIEPU index. Additionally, the negative impacts of the rises in the specifically COVID‐19 based‐constructed PIEPU (DCOVPIEPU) index on the S&P500 and Dow Jones indexes are higher than the negative impacts of the general PIEPU index. This can be interpreted to mean that the larger the magnitude and spread rate of a pandemic, the larger the negative impacts on stock returns. In the sample period of this study, COVID‐19 is the largest and most destructive pandemic compared to H1N1 and Ebola.

The crisis of COVID-19 comes with a calamitous economic stance. The South Asian countries experience their nastiest economic performance in the last four decenniums, and a moiety of the countries are falling into recession. This paper checks the impact of the first,second and third waves of COVID-19 outbreak on the stock market indices of all the South Asian countries, including India, Pakistan, Afghanistan, SriLanka, Bangladesh, Maldives, Nepal, and Bhutan. The study has utilized the Event Study Methodology and results exhibit that COVID-19 decreases the mean returns of all the stock market indices and increases their volatility,which designates that Corona does influence all the stock markets of South Asia in decrementing their returns and incrementing volatility. Overall, the negative effect of the first wave of COVID-19 is not paramount across all the indices except the National Stock Exchange of India (NSE), albeit its second wave did not affect any of the stock market indices significantly. In contrast,the third wave affects the stock markets indices of Pakistan (PSX) and Afghanistan (AFX).

This paper examines whether gold, and gold mining stocks, were an effective hedge during the 2020 global pandemic and 2008-2009 global financial crisis. Prior research suggests that gold's hedging value is most evident during crisis periods, but none has compared the 2008-2009 and 2020 episodes directly. Dynamic conditional correlations and hedge ratios are estimated to determine the impact of rising market volatility on the hedging properties of physical gold and gold mining stocks. The results suggest that gold provided strong hedging value during the global financial crisis but did not consistently exhibit this property in 2020. There was less scope for hedging against losses in 2020 because the market recovered so quickly from the March 2020 lows. This contrasts with the extended stock market weakness following the onset of the global financial crisis.

We examine how the Australian stock market responded to the uncertainties created by the COVID-19 pandemic and whether the stimulus package offered by the Government helped restore confidence in the market. This study finds a negative stock market reaction to the pandemic announcement, however, among two stimulus packages related announcements, the market reacted positively only to “JobKeeper” package. The cross-sectional results suggest that the smallest, least profitable and value portfolios suffered more during the pandemic. Finally, size and liquidity are found to be the significant drivers of abnormal returns. These results generally hold for a battery of robustness checks.

The 1918-1919 Spanish Flu represented the biggest worldwide health threat prior to the 2020 coronavirus pandemic. Although its mortality effects have been widely studied, much less has been done to assess its economic and financial impact. This mini review incorporates findings from recent studies of the Spanish Flu's effect on economic performance and stock market performance in the United States and worldwide. Although US impacts may have been very short-lived, more pervasive effects seem evident in other countries. It also appears that contemporary stock market participants reacted significantly, and negatively, to the surging death rates that were seen during the Spanish Flu.

This paper investigates the relationship between US stock market returns (S&P500) and three indicators of the market, namely implied volatility, implied correlation and liquidity. It also considers the short range dependence between both total confirmed cases and deaths in twelve countries and market movements. We use the two-regime Markov switching model to find the structural break between stock market returns and key stock market indicators. The findings show close dependence between returns and both implied volatility and implied correlation but not with liquidity. The findings indicate the unique role of Italy in crisis transmission.

Although the Federal Reserve's quantitative easing of early 2020 was comparable in scale to 2008-2009, the implications for the growth of money in circulation and future inflationary pressures appear quite different. Absent the unprecedented surge in bank excess reserve ratios seen in 2008 and after, massive monetary base increases imply the possibility of a much larger, and potentially worrisome, increase in the money in circulation. Rising inflation expectations are implied by such phenomena as the surging demand for Treasury Inflation Protected Securities and record highs for gold prices during the summer of 2020. These trends lend some support to market participants evincing concern that the surging money growth is, in fact, a precursor to future inflation. Historical perspective on the 2020 situation is provided by data from the time of the 1918-1919 Spanish flu and available documentation of inflation following medieval and Roman-era pandemics. Indications of extra upward pressure on prices arising from pent-up spending after the epidemic has passed include the surge in bank loans in the aftermath of the 1918-1919 Spanish Flu pandemic.

The coronavirus pandemic in 2020 was the most devastating worldwide health threat since the 1918-1919 Spanish flu. Panel regression analysis for ten countries suggests that European and US stock markets reacted significantly, and negatively, to the surging death rates that were seen during the Spanish Flu. It is possible that the greater death rates for the Spanish Flu visa -vis the coronavirus account for stock market effects being more evident in 1918-1919 than in 2020. JEL codes: G15; N22; N24

The COVID-19 pandemic prompted unprecedented economic stimulus worldwide. We empirically examine the impact of a withdrawal of fiscal stimulus policies on the stock markets. After constructing a database of withdrawal events, we use event study analysis and cross-country regressions to assess the difference between the pre- and post-event stock price returns. We find that markets react negatively to premature withdrawals—defined as withdrawals at a time when the daily COVID cases are high relative to their historical average—likely reflecting concerns about the withdrawal impact on the prospects for economic recovery. The design of a successful exit strategy from COVID-19 policy responses should account for these concerns.

No previous infectious disease outbreak, including the Spanish Flu, has affected the stock market as forcefully as the COVID-19 pandemic. In fact, previous pandemics left only mild traces on the U.S. stock market. We use text-based methods to develop these points with respect to large daily stock market moves back to 1900 and with respect to overall stock market volatility back to 1985. We also evaluate potential explanations for the unprecedented stock market reaction to the COVID-19 pandemic. The evidence we amass suggests that government restrictions on commercial activity and voluntary social distancing, operating with powerful effects in a service-oriented economy, are the main reasons the U.S. stock market reacted so much more forcefully to COVID-19 than to previous pandemics in 1918–1919, 1957–1958, and 1968.

Recent literature reports stock markets around the world reacted to the Covid-19 pandemic with negative returns. However, this reaction was not uniform across countries. In this paper, we postulate that the national-level uncertainty avoidance, which determines how sensitive members of a nation are to uncertainty, moderates the stock markets’ reaction to the pandemic. Using daily data of Covid-19 confirmed cases and stock market returns from 43 countries, we find robust evidence that the decline in stock market returns in response to one percent increase in growth in confirmed cases is stronger for the countries with higher national-level uncertainty aversion.

As the coronavirus pandemic (COVID-19) has amplified so has country responses to it. With COVID-19 taking its toll on humans, as reflected in the number of people infected by, and deaths from, COVID-19, countries responded by locking down economic activity and peoples movement, imposing travel bans, and implementing stimulus packages to cushion the unprecedented slowdown in economic activity and loss of jobs. This article provides a commentary on how the most active financial indicator – namely, the stock price – reacted in real-time to different stages in COVID-19’s evolution. We argue that, as with any unexpected news, markets over-react and as more information becomes available and people understand the ramifications more broadly the market corrects itself. This is our hypothesis which needs robust empirical verification.
