This paper investigates (i) the volatility of Indonesian Islamic, SRI, and Conventional equities, (ii) their serial correlation, and (iii) their dynamic correlation and relationship during the COVID-19 pandemic. Using MGARCH-DCC, our findings suggest that the Islamic index is most volatile but performs more efficiently than the others and exhibits no co-movement with Conventional and SRI during…
This study aims to investigate factors that affect IPO oversubscription on Islamic stocks. Using data of 202 IPOs indexed from Indonesia Sharia Stock Index, this study uses ordinary least squares and quantile regression to test the formulated hypothesis from 2011 to 2020. This study finds that issue price and issue size negatively affect IPO oversubscription. Meanwhile, firm size and raw return…

The Islamic principles in identifying stocks as Shari’ah principles have inevitability restrict the number of stocks that Muslims can invest in and consequently may affect the return from investment. In this paper, we examine the potential of Deep Reinforcement Learning in optimizing the portfolio returns of Islamic stocks. We model stock trading as a Markov Decision Process problem because o…
Volatility of stock returns is a very interesting phenomenon as it impacts the existence of global financial markets. Indeed, the impact of shocks in a country can be transmitted to markets in other countries through the mechanism of transmission, leading to financial instability in related markets (Liu et al., 1998). The present paper aims to determine the best model in describing the volatili…
A strategy that selects stocks based on their historical same-calendar-month returns earns an average return of 13% per year. We document similar return seasonalities in anomalies, commodities, and international stock market indices, as well as at the daily frequency. The seasonalities overwhelm unconditional differences in expected returns. The correlations between different seasonality strate…

The main purpose of this research is to apply five univariate GARCH models to the daily stock returns of four major sharia stock indices. Two symmetric versions of the GARCH model (GARCH and MGARCH) and three asymmetric versions (EGARCH, TGARCH and PGARCH) are employed to estimate and forecast the volatility of four major sharia indices. The results provide strong evidence that all models can …
Standard representative-agent models fail to account for the weak correlation between stock returns and measurable fundamentals, such as consumption and output growth. This failing, which underlies virtually all modern asset pricing puzzles, arises because these models load all uncertainty onto the supply side of the economy. We propose a simple theory of asset pricing in which demand shocks pl…
We show that, after the revelation of corporate fraud in a state, household stock market participation in that state decreases. Households decrease holdings in fraudulent as well as nonfraudulent firms, even if they do not hold stocks in fraudulent firms. Within a state, households with more lifetime experience of corporate fraud hold less equity. Following the exogenous increase in fraud revel…

Overreaction is a phenomenon caused by stock market inefficiencies and also a reaction to certain events. Das and Krishnakumar (2016) explain that some overreaction phenomena violate the theory of capital market efficiency. As experienced by other stocks, Islamic stocks also probably experience market inefficiencies. This study aims to analyse the phenomenon of overreaction in Islamic stocks, …

Although algorithmic trading now dominates financial markets, some exchanges continue to use human floor traders. On March 23, 2020 the NYSE suspended floor trading because of COVID-19. Using a difference-in-differences analysis around the closure of the floor, we find that floor traders are important contributors to market quality. The suspension of floor trading leads to higher spreads and la…
