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....

We document that the stock market's reaction to unscheduled firm-specific news such as credit rating downgrades and 8-K filings is significantly weaker during December as compared to other months. In contrast, the market's reaction to scheduled earnings announcements is not significantly...

Cohen, Malloy, and Nguyen (2020) show that year-over-year changes in annual and quarterly reports of US firms significantly predict future returns: ”changers” generate negative alpha and underperform ”no changers” considerably. I replicate this anomaly for an updated and investable...
