We study the relation between order imbalance and past returns and firm characteristics and test a number of hypothesis including the disposition effect, momentum and contrarian trading, tax-loss selling and flight-to-quality hypothesis. These hypotheses make predictions about investors' buy or...

We use information from over two million trading strategies that are randomly generated using real data, and from strategies that survive the publication process to infer the statistical properties of the set of strategies that could have been studied by researchers. Using this set, we compute...

A significant fraction of firms' financing occurs via public debt markets. Accordingly, we investigate whether financial statement characteristics and other variables that predict equity returns also predict corporate bond returns. Profitability, asset growth, and equity market capitalization...

This paper documents a strong relationship between short-run reversals and stock return illiquidity, even after controlling for trading volume. The largest reversals and the potential contrarian trading strategy profits occur in the high turnover, low liquidity stocks, as the price pressures...

The post-earnings-announcement drift is a longstanding anomaly that conflicts with market efficiency. This study documents that the post-earnings-announcement drift occurs mainly in highly illiquid stocks. A trading strategy that goes long high-earnings-surprise stocks and short...

This paper proposes a trading-based explanation for the asymmetric effect in daily volatility of individual stock returns. Previous studies propose two major hypotheses for this phenomenon: leverage effect and time varying expected returns. However, leverage has no impact on asymmetric...
