This paper investigates the dynamic relation between net individual investor trading and short-horizon returns for a large cross-section of NYSE stocks. The evidence indicates that individuals tend to buy stocks following declines in the previous month and sell following price increases. We...

Different share classes on the same firms provide a natural experiment to explore how investor clienteles affect momentum and short-term reversals. Domestic retail investors have a greater presence in Chinese A shares, and foreign institutions are relatively more prevalent in B shares. These...

We identify a group of "suspicious" firms that use stock splits--perhaps, along with other activities--to artificially inflate their share prices. Following the initiation of suspicious splits, share prices temporarily increase, and subsequently decline below their pre-split levels. Using...

Using account level data from the Shanghai Stock Exchange, we find widespread evidence consistent with insiders manipulating share prices to exploit naïve retail investors. We identify a group of “suspicious” firms that use stock splits—perhaps, along with other misleading activities—to...

Listed Chinese companies can issue A-shares that are held mainly by domestic investors and B-shares that are held mainly by foreign investors. Although these twin shares have identical cash flow rights and are traded in the same location, A-shares are almost always priced higher than B-shares....

The identical cash flow rights of Chinese A and B shares provide a natural experiment that allows us to explore how investor clienteles affect stock return patterns. Chinese domestic retail investors are responsible for the majority of trades in A shares, while foreign institutional investors...

We classify institutions into socially responsible institutions (SRI) and non-socially-responsible institutions (NSRI) based on the value weighted Corporate Social Responsibility (CSR) scores of their portfolio holdings. Controlling for CSR scores, stocks that experience an increase in NSRI...

We develop a model where overconfident investors overestimate their own signal quality but are skeptical of others'. Those investors who are initially uninformed believe that the early informed have learned little, leading the former investors to provide excess liquidity, which, in turn, causes...
