This paper documents that insiders are both contrarians and possessors of superior information. We find that insider trades are positively related to the firm's future earnings performance (proxy for superior cash flow information), positively related to the firm's book-to-market ratio and inversely related to recent returns (proxies for trading against misvaluation). Each relation has incremental explanatory power, yet information about future cash flow changes explains a smaller portion of insider purchases than do proxies for security misvaluation. The relation between insider trades and future earnings performance is amplified (attenuated) as the benefits (costs) to trading on financial performance information increase.

Motivated by extant finance theory predicting that insider trading crowds out private information acquisition by outsiders, we use data for 100 countries for the years 1987–2000 to study whether analyst following in a country increases following restriction of insider trading activities. We document that analyst following increases after initial enforcement of insider trading laws. This increase is concentrated in emerging market countries, but is smaller if the country has previously liberalized its capital market. We also find that analyst following responds less intensely to initial enforcement when a country has a preexisting portfolio of strong investor protections.
