This paper examines the impact of individual investor trading on information asymmetry in the market. In particular, we examine the relationship between the trading volume by individual investors and the corresponding bid-ask spread in the Korean stock market, where the majority of the trading activity is driven by individual investors and therefore information asymmetry can be evident. We find that high trading activity by individual investors increases the bid-ask spread in a short investment horizon, suggesting that individual investors, as uninformed and unsophisticated traders, amplify the degree of information asymmetry in the market through trading. 相似文献

We present an analytical framework to investigate surprises in financial markets. The framework enables us to simultaneously identify and quantify surprises in security price data. By applying the framework to the tick-by-tick data on Japanese government bond futures prices, we find that the Bank of Japan’s introduction of quantitative and qualitative monetary easing in 2013 was one of the most surprising episodes during the period from 2005 to 2016. We also show that traders’ sensitivity to the Bank’s announcements has strengthened since the introduction of the negative interest rate policy in 2016, whereas their sensitivity to economic indicators and surveys has weakened substantially. 相似文献

Using a large proprietary database of intraday high‐frequency trading, we investigate the trading strategies of institutional investors in dealing with the negative environmental event disclosure of listed companies and their impact on markets, aiming to reveal the mechanism of the lack of “green efficiency” in China's capital market from the perspective of institutional investors. The results show that institutional investors react to negative environmental events prior to the announcements, indicating premature information leakage in the market; in addition, their trading behaviors mitigate the immediate effect of negative environmental event announcements on stock price. After the event is disclosed, institutional investors engage in short‐term selling and long‐term buy and hold. This trading strategy undermines the irrational selling of individual investors in the event of disclosure, short‐term decline in stock price, and long‐term reversal of market overreaction. In a China context, institutional investors generally take environmental information into consideration. However, they fail to recognize the long‐term value effect of negative environmental events and instead cater to trading strategies towards market volatility. 相似文献

This study analyzes the effect of firm-specific information risk, measured by accruals quality, on the cost of capital using institutional investors’ trading behavior. Institutional investors in firms with lower accruals quality increase their net selling in later years. Furthermore, these investors’ net selling is relevant to the innate and discretionary factors of accruals quality. This relationship is stronger for foreign institutions than for domestic institutions, and it is mostly observed under favorable macroeconomic conditions. We do not observe this relationship for large business groups connected by shares. 相似文献
