Does Insider Trading Really Move Stock Prices?

  • Chakravarty, Sugato
  • McConnell, John J.

Prior studies have reported a positive correlation between insider trading and stock price changes. The implication of these studies is that insider (i.e., informed) trades have a differential impact on price discovery than non-insider (i.e., uninformed) trades. Based on these results, various scholars have argued for the legalization of insider trading to facilitate rapid price discovery. We analyze the trading activity of a confessed inside trader, Ivan Boesky, in Carnation’s stock just prior to the acquisition of Carnation by Nestle, and find that our tests are unable to distinguish the price effect of Boesky’s (i.e., informed) purchases of Carnation’s stock from the effect of non-insider (i.e., uninformed) purchases. Our conclusion survives extensive robustness tests and has methodological and public policy implications.
