We test whether momentum-based strategies remain profitable after considering market frictions induced by trading. Intra-day data are used to estimate alternative measures of proportional (spread) and non- proportional (price impact) trading costs. A cross-sectional model of the relation between...

We test whether momentum strategies remain profitable after considering market frictions induced by trading. Intraday data are used to estimate alternative measures of proportional and non-proportional (price impact) trading costs. The price impact models imply that abnormal returns to portfolio...

This paper develops a formal model of the effect of time-varying asymmetric information on the timing and pricing of equity issues when managers are better informed than outside investors. We assume that as time passes, the adverse selection problem becomes more severe as more managers receive a...

If equity markets are financially integrated, the price of risk should be the same across markets. If the markets are not financially integrated - possibly because of barriers to capital flows across markets - the price of risk may differ across markets. The author investigates one measure of...

In this paper we develop a measure of liquidity, price impact, which quantifies the change in a firm's stock price associated with its observed net trading volume. For a large set of institutional trades we compare out-of-sample, characteristic-based estimates of price impact to actual price...

Motivated by the literature on investment flows and optimal trading, we examine intraday predictability in the cross-section of stock returns. We find a striking pattern of return continuation at half-hour intervals that are exact multiples of a trading day, and this effect lasts for at least 40...
