In the past two years, the global and Indonesian economies
have been severely impacted by the COVID-19 pandemic,
leading to below-target and negative growth rates worldwide.
Indonesia declared the pandemic in March 2020, resulting in
disruptions and lower-than-expected economic growth, with the
first quarter of 2020 recording 2.97% growth compared to a
consensus of 3.5-4.0%. Key sectors like manufacturing, retail,
construction, and mining contracted, while household
consumption dropped to 2.84% from 5.01% the previous year.
This summary presents inflation and economic growth data in
Indonesia as of October 2020 from the Central Statistics Agency.
The research outcomes serve as reference material for
government policy-making during crises, offer insights to
infrastructure issuers in the capital market, assist investors in
stock transactions and projections, and provide general
knowledge about Indonesia's capital market.
INTRODUCTION
In the current period of global integration, investment is one of the important factors in
encouraging a country's economic growth, one of which is through the capital market industry as
a source of financing for the business world and a means of investment for the community
(Guniarti, 2014). Investment is a commitment to a number of funds or other resources made with
the aim of obtaining profits in the future. One popular form of investment is stocks. In 2021,
there is an evaluation of changes in the stock sector conducted by the Indonesia Stock Exchange
consisting of energy (alternative energy, oil, gas, &; coal), basic materials, industrials (industrial
goods, industrial services, multi-sector holdings), consumer non-cyclicals (food & beverage, food
& staples retailing, nondurable household product, tobacco), consumer cyclicals (automobiles &
components, consumer services, household goods, leisure goods, media &; entertainment,
retailing), healthcare (healthcare equipment & providers, pharmaceuticals &; health care
research), financials (banks, financing service, holding &; investment companies, insurance,
investment service), properties & real estate, technology (software & IT services, technology
hardware & equipment), infrastructures (heavy constructions & civil engineering,
telecommunication, transportation infrastructure, utilities) transportation & logistics (logistics &
deliveries, transportation), listed investment product (bonds, investment trusts)(Anggarini, 2016).

the company announced that it had formed a new subsidiary PT Waskita Toll Road to manage
future toll road projects. (PT Waskita Karya (Persero) Tbk, n.d.) Eleven large companies are
included in the construction infrastructure sector which is likely to be greatly affected in terms of
its business industry in the midst of a crisis, in addition to other reasons such as hampered
development, temporarily shifting concentration from business lines to health management,
limited mobility so that development cannot be carried out directly in the field.
METHOD
Basically, this research is a combination of quantitative and qualitative research.
Quantitative is used to calculate the influence of fundamental factors of financial ratios DER, OPM,
ROA, ROE, NPM and technical factors of trading volume, individual stock price indices related to
stock returns so as to use secondary data obtained from IDX Annualy Statistics, Annual Report
of Research Objects, Yahoo Finance, Investing, and some from capital market and securities
websites (Badan Pusat Statistik, n.d.)(Abidin, Suhadak, & Hidayat, 2016). The data obtained will
be processed with SPSS & RStudio software using panel data regression tests (ANDRIANTI, 2017).
Meanwhile, qualitative testing is used in designing a risk management framework from the

influence of variables in statistical tests of panel data regression that have been carried out
previously (Mojtahedi, Mousavi, & Makui, 2010)(Hanafi, 2014). The analytical descriptive study
approach is carried out in collecting and revealing various problems and research objectives to
be achieved (Fuady, 2014). Descriptive qualitative research is a research method based on the
philosophy of postpositivism which is used to examine natural objective conditions where
researchers act as key instruments (Sugiyono, 2010).
RESULTS AND DISCUSSION
Data Description
Descriptive Statistical Results
Descriptive statistics are used to describe data that can be seen from minimum,
maximum, mean, and standard deviation. Based on sampling criteria or limitations, the sample
used was 11 construction infrastructure sector companies with a four-year period (Manab,
Othman, & Kassim, 2012). This sample will also distinguish normal conditions and samples of
crisis conditions that are each two year period (Horton & Kleinman, 2015).
This study uses seven independent variables to determine ROA, ROE, NPM, OPM, DER,
Trading Volume, and Individual Stock Price Index on stock return (Exchange, 2021). The
dependent variable in this study is stock return which is measured using the annual closing price.
to provide an overview of stock returns as dependent variables and ROA, ROE, NPM, OPM, DER,
Trading Volume, and Individual Stock Price Index as independent variables.
Descriptive Statistical Analysis
ACST stock descriptive statistics show that there is no missing data for all variables, with
ranges (minimum-maximum) for Stock Return 11.47, ROA 45.81, ROE 1395.55, NPM 115.17,
DER 11224.05, OPM 104.16, Trading Volume 22.92 and Individual Stock Price Index 108.63.
Meanwhile, for the results of the standard deviation compared to the mean value, it is found that
all variables show standard deviation > the mean, which means that the data is increasingly
diverse (Munawir, 2010).
Test the Difference Between Normal Stock Returns and Crisis Times
Panel data regression model selection testing is done so that we can determine the model
to be used whether it is a common effect model (CEM), fixed effect model (FEM) or random effect
model (REM).
Classical Assumption Test
Classical assumption testing is a test that must be fulfilled in conducting analysis using
panel data regression including residual assumptions that are normally distributed, identical, and
independent (Artha, Achsani, & Sasongko, 2014). Assuming normality, OLS estimators are
unbiased, efficient, and consistent. On the other hand, the probability distribution for the OLS
estimator can be obtained easily, since the normal distribution properties of each linear function
of a normally distributed variable are themselves normally distributed. Classical assumption tests
include the Normality test, the Multicollinearity test, and the Heterokedasticity Test.
CONCLUSION
The conclusions drawn from the research, conducted according to the planned
methodology, can be summarized as follows: Firstly, there is a statistically significant difference
in the average return between normal stocks (average return of -2.5986) and stocks during times
of crisis (average return of 3.2988), indicating a distinction in their performance. Secondly, in
normal conditions, various financial variables such as ROA, ROE, NPM, DER, OPM, Trading

Crisis With Stock Return

Volume, and Individual Stock Price Index collectively influence stock returns, as their p-value of
0.00028133 is less than 0.05. Conversely, during crisis conditions, these variables no longer
significantly affect stock returns, with a p-value of 0.53414 exceeding 0.05. Furthermore, both in
normal and crisis conditions, the Individual Stock Price Index is the sole independent variable
influencing Stock Return, given its p-values of 3.435e-06 (normal conditions) and 0.0480 (crisis
conditions), both below the 0.05 threshold. Lastly, the research identified seven financial risks
categorized as low risk (return on equity, debt to equity ratio), medium risk (net profit margin,
individual stock price index), and high risk (operating profit margin, return on assets, and trading
volume), each accompanied by specific risk mitigation solutions (Ernawati & Nugroho, 2012).
These findings offer valuable insights into the relationship between financial variables, stock
returns, and risk management, applicable in both normal and crisis periods.
