The Cost

Institutional and individual investors are the two important players in the stock market. Together, they determine the price of the stock market. In this paper, an evolutionary game model that contains the two groups of players is proposed to analyze the stock price synchronicity considering the impacts of investors’ decisions on stock investment. Factors affecting investors’ decisions include the potential revenue or loss, the probability of gain or loss, and the cost of corresponding behavior. The proposed game model is analyzed by replicator dynamics equations and simulation of the evolutionary equilibrium strategy under different circumstances. The analysis shows that the operating cost of institutional investors, the cost of information collection before trading, and the expected loss that may be punished by regulators are the key factors that affect the evolutionary game system between institutional investors and individual investors. In addition, reducing the speculation in the market and increasing the information access of investors through the serious operation mode of institutional investors and the strengthening of the market information disclosure mechanism are beneficial to alleviate price synchronicity in stock market.

Sustainability Reports

Stock Price Synchronicity is a calculation used to show the proportion of the company's internal and external information accumulated into the stock price. This study aims to examine internal information in the form of sustainability reports and earnings quality on stock price synchronicity. Furthermore, this study also aims to examine the moderating effect of institutional investors as an indicator of sophisticated investors. The population in this study is a go-public manufacturing company on the Indonesia Stock Exchange (BEI). The sample was determined by the purposive sampling method. This research uses multiple regression analysis methods with a panel data form. The results showed that companies with a higher quality of sustainability reports had lower stock price synchronicity and institutional investors did not have a moderating effect in this relationship. The results also show that companies that have higher earnings quality have high stock price synchronicity as well. This relationship changes when the institutional investor moderation variable is added. Companies with higher earnings quality have lower stock price synchronicity values.

Moderating Role

Purpose The purpose of this paper is to examine the association between politically connected (POLCON) firms and stock price synchronicity, and whether this association can be attenuated by institutional investors. Design/methodology/approach This paper uses an ordinary least square regression model to examine the association between POLCON firms and stock price synchronicity; institutional ownership and stock price synchronicity; the moderating role of institutional ownership on the association between POLCON firms and stock price synchronicity; institutional domiciles and stock price synchronicity; and the moderating role of institutional domiciles on the association between POLCON firms and stock price synchronicity. Findings The result shows that POLCON firms are positively associated with stock price synchronicity. Further, the author also finds that institutional monitoring, through higher ownership by local institutional investors is associated with lower stock price synchronicity. In addition, this study documents evidence that institutional investors, particularly local institutional investors can improve stock price informativeness in POLCON firms. Research limitations/implications The results suggest that POLCON firms are plagued by severe agency problems, resulting in limited flow of firm-specific information to the capital markets. However, the author shows that POLCON firm’s agency problems can be attenuated through effective monitoring by institutional investors. Further, institutional domiciles are shown to be significantly associated with stock price synchronocity. However, effective monitoring is largely driven by local institutional investors, in line with the geographical proximity theory. Practical implications The results suggest that regulators should increase their surveillance and monitoring effort, particularly on firms with close ties to the government. In particular, POLCON firms should be required to be more transparent in their corporate dealings. Additionally, auditors should intensify their audit efforts on POLCON firm to provide more reliable financial information to minority shareholders, investors and analysts. Finally, institutional investors should be incentivized by the Malaysian Securities Commission, via, the code of governance to play an effective monitoring role in Malaysian firms. Originality/value This study reveals that POLCON firms’ severe agency problems can be alleviated by effective institutional monitoring. Further result identifies institutional domiciles as a significant factor in influencing monitoring effectiveness in POLCON firms. This paper provides insights into the dynamic interaction between political connections, institutional monitoring, firm governance and capital markets behavior of an emerging market.
