This study investigates the relationship between insider trading and fraud. We find that in the presence of fraud, insiders reduce their holdings of company stock through high levels of selling activity as measured by either the number of transactions, the number of shares sold, or the dollar amount of shares sold. Moreover, we present evidence that a cascaded logit model, incorporating insider trading variables and firm-specific financial characteristics, differentiates companies with fraud from companies without fraud.

We provide evidence that corporate tax status is endogenous to financing decisions, which induces a spurious relation between measures of financial policy and many commonly used tax proxies. Using a forward‐looking estimate of before‐financing corporate marginal tax rates, we document a negative relation between operating leases and tax rates, and a positive relation between debt levels and tax rates. This is the first unambiguous evidence supporting the hypothesis that low tax rate firms lease more, and have lower debt levels, than high tax rate firms.

This study evaluates the relation between security returns and funds-based earnings components. We document that proxies for market expectations of the components that are based on measures of historical serial- and cross-dependencies are substantially more accurate than random-walk proxies. Moreover, we detect significantly higher valuations of the operating cash flow component of earnings, relative to current accruals, when market expectations are represented using the dependency-based predictions. Such differential valuation is not detectable for random-walk representations. Contrary to results in Ali (1994), we find incremental information in unexpected cash flows over the whole spectrum (moderate and extreme) of unexpected cash flow realizations.

This paper investigates the market reaction to short sales on an intraday basis in a market setting where short sales are transparent immediately following execution. We find a mean reassessment of stock value following short sales of up to −0.20 percent with adverse information impounded within fifteen minutes or twenty trades. Short sales executed near the end of the financial year and those related to arbitrage and hedging activities are associated with a smaller price reaction; trades near information events precipitate larger price reactions. The evidence is generally weaker for short sales executed using limit orders relative to market orders.
