We report three new findings that rely upon the high-low price range as an estimate of stock return variance. The predictability of variance is associated with persistence in high prices and with correlated shocks to high and low prices. Excess stock returns are positively related to anticipated...

The authors present the first evidence that initial ratings of commercial paper influence common stock returns. Highly rated industrial issues of commercial paper, unaccompanied by bank letters of credit, are associated with significantly positive abnormal returns; lower-rated issues are not....

That corporate insiders earn profits from stock trading does not surprise most financial economists, but that outsiders can earn abnormal returns by using pub licly-available, insider-trading data constitutes a serious exception to stock-market efficiency. The authors show that this anomaly...

Gain and loss, calculated from the upside and downside portions of return distributions, play a pivotal role in the two-state model. A two-state economy possesses a universal gain-loss ratio (G/L) for all assets that is related to the ratio of state prices and to the familiar risk-neutral...

Managers have repeatedly indicated in surveys that stock splits are intended to improve liquidity. However, previous studies using bid-ask spread and turnover as measures of liquidity find results to the contrary. This paper offers a new perspective on the issue. Stock splits can make buying...

We estimate speeds of adjustment of individual stock prices to private information using daily data. We use a model in which private information gives rise to return variance and private information decays linearly over time. We find that, on average about 85 to 88 percent of private information...

We report three new findings that rely upon the high-low price range as an estimate of stock return variance. The predictability of variance is associated with persistence in high prices and with correlated shocks to high and low prices. Excess stock returns are positively related to anticipated...

This article examines the relation between stock returns and a set of operating decisions: layoffs, operation closings, and pay cuts. We find evidence that cost-cutting measures occur after significant stock price declines. Announcements of layoffs and temporary operation closings are associated...

We examine stock price behavior in response to initial coverage, buy recommendations that are pre-released to important clients before the stock market opens, and find a strong positive valuation effect at the open. On average, it takes five minutes of trading for NYSE/AMEX stocks and 15 minutes...
