Abstract: Although WHO has declared the pandemic end, the underexplored area of study around COVID-19, macro-

financial, conventional, and Islamic stock markets should be conducted. Therefore, this research remains

relevant since a market downturn can happen anytime in the future, and the world will face dynamic changes

in investors' behavior. We aim to investigate the drivers of the Conventional and Islamic stock markets, which

mainly consider the global pandemic COVID-19 and Macro-financial forces. The main methodology applied

panel autoregressive distributed lag (ARDL). This research discovers the following findings: (1) conventional

stocks highly rely on the confidence index of the COVID-19 vaccine, whereas Islamic stocks remain more

resilient; (2) A safe-haven role of Islamic stocks during global market turbulence and outperform their

counterparts; (3) government policies boost the confidence of both stock markets; and (4) conventional stocks

are much more dominant than Islamic stocks. Islamic stocks provide safe-haven attributes during market

turmoil, whereas conventional stocks take time to recover. We offer suggestions to investor decision-making,

regulators, and government policies.

1 INTRODUCTION

Although the global COVID-19 pandemic has come

to an end, as announced by WHO at the beginning of

May 2023, the underexplored area of study around

COVID-19 and stock markets is still crucial to be

investigated. Market uncertainty and economic

conditions greatly affect investment decision-

making, thus determining the future direction of

Islamic and conventional stocks (Albaity et al., 2023).

COVID-19 shocked the world economy—especially

the stock markets—both conventional and Islamic

(Al-Awadhi et al., 2020). Conventional stocks (CS)

experienced incisive declines in the early pandemic

stages. The S&P 500, Nikkei, and Hang Seng indices

fell by 34%, 20%, and 18%, respectively (Al-Awadhi

et al., 2020; Zhang et al, 2020). COVID-19 also

affects the Islamic Stock (IS) market, but the recovery

outperformed compared with their counterparts, the

CS market (Nomran and Haron, 2021). IS

experienced a smaller decline in its return and

rebounded rapidly (Chowdhury et al., 2022). The

arrival of vaccines resolved the shock due to the

global COVID-19 pandemic. It gave new hope for the

economy and thus the stock markets. It brought

positive stock markets and economic breakthroughs

globally (Rouatbi et al., 2021).

Research about vaccines of COVID-19 and

financial assets (i.e., stocks) have been increasing

recently. A positive stock market reaction was shown

when the COVID-19 vaccines were produced and

distributed (Demir et al., 2021; Rouatbi et al., 2021;

Khalfaoui et al., 2021; Behera et al., 2022).

Furthermore, people are more optimistic about

investing in healthcare stock due to vaccine doses

(Jeremiah et al., 2023). The vaccination rate denoted

an exponential increase and signaled bright news for

investors. Thus, global stock markets remain less

volatile (Rouatbi et al., 2021). Meanwhile, it was

found that vaccination was negatively insignificant to

the return of the IS market in Malaysia (Tee and Kew,

2022).

A novelty research by Havidz et al., (2023),

constructed the vaccine confidence index (VCI),

which was derived from the first and second doses,

creating confidence in individuals and thus promoting

herd immunity. When herd immunity was formed, the

economy would rebound eventually. They further

explored VCI impacts on the cryptocurrencies and

found that VCI positively impacted Bitcoin returns.

This result was confirmed by Havidz et al., (2024).

The impact of VCI on CS and IS markets has been

unexplored; hence, we conducted this study. In

addition to VCI, we utilized additional COVID-19

indices (i.e., the index of global fear (GFI), the index

of stringency (SI), and the panic index of COVID-19

(CPI)).

Constructed by Salisu and Akanni (2020), GFI

negatively impacted the stock market. It was further

agreed by others (Makun, 2021). Furthermore, GFI

was also utilized to find its effect to commodity

(Salisu et al., 2020). SI was also employed because a

high stringency index will cause difficulties in

business activities (Scherf et al., 2022). Nevertheless,

government policy in breaking the chain of COVID-

19 infection could accelerate economic recovery. It

was assumed that when the economy recovers, the

stock market will rebound eventually (Aggarwal et

al., 2021; Chang et al., 2021; Gu et al., 2022). CPI

was utilized to find the impact on the stock market

(Aggarwal et al., 2021), and major fiat and

cryptocurrency volatility (Umar and Gubareva, 2020.

Both GFI and CPI were utilized to find their impact

on cryptocurrency return (Havidz et al., 2023) and

Bitcoin volatility (Tiffani et al., 2023).

Besides COVID-19 factors, macro-financial

factors also determine stock market movement (Pan,

2023). Therefore, we include three macro-financial

factors (i.e., index of financial stress (FSI), rates of

foreign exchange (FOREX), and index of volatility

(VIX)) to avoid biased findings because different

factors could be executed concurrently. Compared

with CS, IS studies during COVID-19 were found to

be very limited. There was a dearth of studies of FSI,

and scant studies of FOREX (Dewi et al., 2022) and

VIX (Francis & Ambilikumar, 2021; Grima et al,

2021).

The literature on comparison studies between CS

and IS grew during the pandemic (Nomran and

Haron, 2021; Widjaja et al., 2024), but this current

research was executed in different ways. Therefore,

we addressed the research gap. We contributed to the

literature threefold. First, this was the first study that

utilized VCI as a determinant of CS and IS. Prior

studies investigated the impact of VCI on the

cryptocurrencies’ return (Havidz et al., 2023, 2024).

Secondly, we scrutinized two main clusters (i.e.,

global COVID-19 pandemic indices and macro-

financial factors) as the determinants, which, as far as

we knew when conducting the study, had not yet been

investigated. Thirdly, instead of executing a one-

sided market, we conducted a comprehensive study

that compared CS and IS markets during market

turbulence and how the range of determinants may

have affected.

2 DEVELOPMENTS OF

HYPOTHESES

2.1 Covid-19 Indices

VCI is a new proxy that was initiated by populations

receiving full vaccination and it drove economic

recovery (Havidz et al., 2023). Once the economy

recovered, it drove stock prices—and their returns—

up (Demir et al., 2021; Rouatbi et al., 2021). When

total vaccination increased, the closing price of CS

also increased (Khalfaoui et al., 2021; Behera et al.,

2022). On the contrary, vaccination was ineffective in

improving IS returns in Malaysia (Tee and Kew,

2022). GFI is an index which composes reported

deaths and cases, and it revealed the higher fear that

was perceived by people prompted a negative

influence on CS (Salisu and Akanni, 2020; Makun,

2021). However, other research revealed insignificant

co-movement between GFI with CS and IS returns in

Pakistan (Ali et al., 2022).

SI is a government policy related to restrictions

including workplace closure and travel bans. Higher

SI impediments business activities and leads to a

stock market downturn (Scherf et al., 2022). This

policy suppresses the infection rate and elevates

people’s confidence, thus ameliorating the

performance of CS (Gu et al., 2022; Chang et al.,

2021). On the contrary, the stringency of government

did not boost IS performance (Hersh et al., 2023).

However, recently, COVID-19 has been considered

FEMIB 2025 - 7th International Conference on Finance, Economics, Management and IT Business

210

as part of people's lives and treated like other common

diseases. Thus, people and the stock market have

started to adjust. Hence, stock markets start to

recover. CPI is a proxy that refers to panic sentiment

and circulating news. The increase in public panic

invokes a diminution of CS market and affects stock

returns negatively (Aggarwal et al., 2021). COVID-

19 pandemic induced stock market panic and

enhanced volatility in daily returns (Nomran and

Haron, 2021). Meanwhile, IS was less volatile in

response to pandemic news (Ashraf, 2020).

Therefore, we proposed as following hypotheses:

: Vaccine Confidence Index (VCI) positively

impacted to both stock indices return, conventional

(CSI) vs. Islamic (ISI)

: Global Fear Index (GFI) negatively/positively

impacted to both stock indices return, conventional

(CSI) vs. Islamic (ISI)

: Stringency Index (SI) negatively/positively

impacted to both stock indices return, conventional

(CSI) vs. Islamic (ISI)

: COVID-19 Panic Index (CPI)

negatively/positively impacted to both stock indices

return, conventional (CSI) vs. Islamic (ISI)

2.2 Macro Financial

FSI is a proxy to measure financial markets stress

degree (Kaplanski and Levy, 2010). When the FSI is

higher than the threshold, this denotes the anomalous

market where investment decisions are riskier (Sun et

al., 2023). Stock returns will decrease along with an

increase in FSI (Christopoulos et al., 2011; Ftiti and

Hadhri, 2019). The higher strain level leads to lower

returns, both with CS and IS (Aloui et al., 2021).

Stock value increment would decrease the price of

local currency to the USD (strengthening the value)

and vice versa (Khan, 2019; Qin 2018). The COVID-

19 pandemic debilitated many countries’ economies

resulting in an impairment of those countries’

exchange rates. Therefore, the CS return declines

(Mroua and Trabelsi, 2020; Topcu and Serkan, 2020).

VIX is the fear index in the stock market. Higher

VIX leads to higher uncertainty of CS (Fernandes et

al., 2014; Shu and Chang, 2018), and thus lower the

CS return. The worsen COVID-19 cases led to a

higher perception of risk and reduced the confidence

of stock market investors (Francis & Ambilikumar,

2021; Grima et al., 2021). The fluctuations of VIX are

important predictors of IS (Ftiti and Hadhri, 2019;

Paltrinieri et al., 2019). Yet, IS was more stable and

predictable through the outbreak and proved less

volatile than CS (Ali et al., 2022). Therefore, we

proposed as following hypotheses:

: Financial Stress Index (FSI) negatively impacted

to both stock indices return, conventional (CSI) vs.

Islamic (ISI)

: Foreign Exchange (FOREX) negatively impacted

to both stock indices return, conventional (CSI) vs.

Islamic (ISI)

: Volatility Index (VIX) negatively impacted to

both stock indices return, conventional (CSI) vs.

Islamic (ISI)

3 DATA AND METHODOLOGY

3.1 Data

We selected the countries around the world based on

the availability of vaccine data for them to meet the

criteria of our sample. There were 249 countries with

available data listed by OurWorldInData (2022), but

only 14 countries with complete vaccination data

were selected with additional criteria applied.

South Korea had the most recent vaccination

program, only starting on 26 February 2021, among

our selected countries as the sample. Thus, the

starting period was benchmarked from South Korea.

Since the VCI is our variable of interest and its

computation included the incubation period, 𝑉𝐶𝐼 =

we applied a 28-day lag based on the most-used

vaccine in each country of our samples. Employing

daily data in our research, the indices of COVID-19

(i.e., VCI, GFI, CPI and SI) have seven-day daily

data. Hence, we interpolated the five-day data for the

remaining variables to seven days.

Our data spanned from 27 March 2021 to 3

December 2022. We transformed the variables to the

change value ((Pt – Pt-1)/Pt) to allow an apples-to-

apples comparison. Leaving SI and FSI using global

data. We concluded to utilize 13 indicators in this

paper consisting of two dependents (i.e., CSI and ISI),

seven independents (i.e., VCI, GFI, CPI, SI, FSI,

FOREX, VIX), and two control variables for each

type of markets (i.e., CSMC, ISMC, CSVOL and

ISVOL). Table 1 reports the data sources and

summary of descriptive.

3.2 Unit Root Test and Panel ARDL

Levin et al. (2002) proposed a unit root test called the

LLC (Levin, Lin, and Chu) test. Table 2 shows the

LLC's findings, which documented that all variables

were significant at level, except for FSI. Afterward,

we used the first difference and verified that all

variables were stationary at the first level.

Mixed stationarity at the level and the first level

exists hence the most appropriate method is panel

autoregressive distributed lag (ARDL) (Pesaran et al.,

1999). A similar approach was also utilized by prior

works (Havidz et al., 2023, 2024). By using the

Hausman test (1978) to choose the most suitable

model, three estimators were applied (i.e., dynamic

fixed effects (DFE), mean group (MG), and pooled

mean group (PMG) and). The model of the ARDL

panel can be explained as follows:

4 RESULTS AND DISCUSSIONS

As suggested by the Hausman test, the long-run

results should refer to the MG estimator for CSI,

while the PMG estimator should be referred to ISI

(see Table 3).

Our results support the entire hypotheses (H

, H

, and H

), except H

. It is revealed that VCI

positively impacted CSI significantly, while it was

insignificant for ISI. Our results support prior works

(Khalfaoui et al., 2021; Behera et al., 2022; Tee and

Kew, 2022). It indicates that fully vaccinated people

increase confidence in the economy (Havidz et al.,

2023), hence the stock returns bounced back. The

conventional and Islamic stocks rebounded, and the

behavior of investors tended to re-buy the stocks.

Conventional stock is highly reliant on the

vaccination rate which leads to a much more stable

market (Khalfaoui et al., 2021; Behera et al., 2022).

However, Islamic stocks applied Shariah law which

prohibited excess risk and emphasized ethical-

oriented trade in doing business (Jawadi et al., 2014).

Hence, Islamic stocks are much more resilient during

market turbulence.

GFI implied a negative insignificant relationship

with CSI. People are getting used to the COVID-19

outbreak, and the level of fear has started to decrease,

driving stock prices up and, therefore, the returns.

These findings are in line with prior works (Salisu and

Akanni, 2020; Makun, 2021). However, a positive

significant impact of GFI on ISI was documented.

Islamic stocks serve as safe-haven assets (SHA),

similar to gold, because of their ability to remain

stable during global crises (Hasan et al., 2021).

Further, investors highly consider Islamic stocks in

the inclusion of the portfolio during the crisis as it

remains as defensive sector (Jeremiah et al., 2023). SI

impacted positively and significantly on both CSI and

ISI. The government's policy in managing COVID-19

increased public confidence in the stock market. This

is also in line with previous findings (Chang et al.,

2021; Gu et al., 2022). Moreover, people’s fear is

lessening regarding COVID-19 as they have adapted

to the notion that COVID-19 can be seen as part of

daily existence. Therefore, they are no longer

panicked by the situation. These results contradicted

prior works (Aggarwal et al., 2021).

FSI impacts positively on both, but is significant

to ISI, while insignificant to CSI. Our results

contradicted previous studies (Christopoulos et al.,

2011; Ftiti and Hadhri, 2019). As COVID-19 had

been underway for a year, thus facing financial

difficulties, the stock markets started to understand

and adjust the conditions. Therefore, stock markets

start to rebound during the stress. Investors’ behavior

certainly does not stop looking for the best stocks

when the market goes down. Prior studies showed

that ISI outperformed CSI (Nomran & Haron, 2021).

Therefore, investors are more interested in Islamic

stocks as it serves as a safe haven.

The exchange rate negatively impacted both

markets but is significant for CSI, while it is

insignificant for ISI. Most indices used around the

world are dominated by conventional indices.

Therefore, the volume of exchange rates for the

conventional stock is greater than the counterpart,

Islamic indices. Our findings are in line with prior

work (Khan, 2019). Moreover, the tendency of

people’s stock consumption leads to the exchange

rate movement (Mroua and Trabelsi, 2020). VIX

shows a negative relationship with both CSI and ISI.

It proves that the less volatile the market, the more

people will invest. This result was supported by

Francis and Ambilikumar (2021) and Grima et al.,

(2021). VIX is determined by the movement of the

S&P 500 which is considered as conventional stocks.

Therefore, CS is more likely to be impacted than IS.

Furthermore, both market caps have a positively

significant impact on CSI and ISI. Indeed, the

growing market cap implied the growth of stock

markets as it gained more investors, thus affecting the

returns. Meanwhile, the volume of both markets

remains a weak determinant of returns compared with

the market caps.

Overall, the short-run results of CSI supported

several significant variables. Although the number of

fully vaccinated people keeps increasing, investors

still question how quickly it will stabilize the

conventional market as recovery takes time.

213

Moreover, the outbreak keeps the market stressed

which leads to investors’ anxiety; they will not invest

in the conventional market when turbulence occurs.

The money supply is affected by hot money inflow

and leads to greater stock returns. COVID-19 has

been going on for a brief period but will recede in

time. Therefore, most of the factors were revealed to

be insignificant in the short run. Likewise, Islamic

stocks remained stable and resilient compared with

their counterpart, conventional stocks.

5 CONCLUSIONS

Islamic stocks were found to be more resilient during

high turbulence compared to its counterpart,

conventional stocks. Our findings benefit investors

and suggest the inclusion of Islamic stocks in their

investment portfolio to mitigate the risks. Islamic

stocks are suggested to investors who aim for long-

term behavior investments because they are more

resilient no matter how bad the economy. Meanwhile,

investors who aim for a quicker, higher return may

consider conventional stocks, yet they should be able

to bear higher losses when high uncertain times occur.

Governments should be able to control and encourage

society to be fully vaccinated as well as get booster

doses to keep the economy stable. The COVID-19

vaccine should be an annual vaccine program

provided by the government. This research is limited

to stock indices and could be further examined in a

company's level data to have a better suggestion for

the stock pick. Further, it is interesting to include

emerging countries and compare them with

developed countries to assess the navigation during

uncertain times of these countries.
