In this paper we examine the profitability of corporate insider trades in the volatile markets of 2000-2003. Insiders are known to be contrarian traders. We hypothesize that profits from both contrarian trading and from trading based on useful inside information are large in volatile markets. We find that insider purchases are negatively related to firm size and recent stock returns and positively related to the firm's book-to-market equity ratio. Even after adjusting for contrarian trading, we find that insider trades generate significantly large future profits. This shows that insiders trade on useful private information and that such trades are profitable in volatile markets.

Insider acquisitions of shares are supposed to align the interests of managers and shareholders. Thus, purchases are typically viewed as positive signals. However, if the transactions do not put insiders' wealth at risk, perhaps this conclusion is premature. We test this idea by focusing on loan financing of insider share acquisitions. We find that loan-financed insider purchases and option exercises earn lower profits than do counterparts that are not loan financed. Our results also suggest that loan-financed insider purchases are an additional method to move an executive quickly to a target level of incentives.

We examine the relation between dividends and information asymmetry by using insider returns as a proxy for information asymmetry. We find that dividends are negatively related to returns to insider trades across firms. Firms that pay consistently high dividends have lower insider returns than do firms that pay consistently low dividends. These results do not support traditional dividend signaling models. Rather, they are consistent with the proposition that firms with the highest dividends have the lowest levels of information asymmetry.
