Abstract

This study evaluates the interactions between, and informativeness of, insider trading and analyst recommendations. We find that analyst recommendations significantly affect subsequent insider trading, but not vice versa. Surprisingly, in aggregate, insiders buy more shares following analyst downgrades and sell more shares following upgrades. This pattern persists even after controlling for analysts’ momentum and insiders’ contrarian trading preferences. Analysts, in contrast, do not systematically take into account insider trading when revising their recommendations. More importantly, we show that these two information signals complement each other although insider buying could be a singularly strong signal that substitutes the informativeness of analyst recommendations under certain circumstances. Overall, our findings highlight the important dynamics and financial market consequences between the two crucial groups of information providers.
