What drives individual investors in the bear market?

This study uses a unique dataset from a large anonymous brokerage firm to examine the net investment of individual investors during a bear market. The study's empirical evidence reveals that individual investors provide liquidity by acting as net buyers. Particularly, male and younger investors tend to have a higher buying intensity than the others during the market downturn. Besides, better performances when the market crashed encourage investors to be overconfident, thus exhibiting self-attribution bias since we do not find similar results in the bull-market subsample. Results from the stock-level analysis imply that investors tend to buy stocks with worse short-term past performance, higher liquidity, and larger market capitalization. Our findings on the individual investor trading behaviour cannot be explained by either a superior stock-picking ability or a higher tendency to gamble during the market downswing.
