Can I make money investing in stocks that insiders are buying? Is there any link between stock returns and insider buying and selling activity. Researchers and academics have been investing time and effort to answer these questions over the past several decades. And luckily, we have more than enough data points to conclude that yes, keeping tabs on insider buying is important.

In a research paper entitled Are Insider Trades Informative? Josef Lakonishok from University of Illinois at Urbana-Champaign and NBER and Inmoo Lee from Korea Advanced Institute of Science and Technology analyzed insider buying and selling activity for companies trading on NYSE, AMEX, and NASDAQ for the period starting 1975 through 1995. The research found out that insiders in aggregate are contrarian investors and their returns are better than the normal contrarian investing strategies. The report also said that insider buying is indicative of important information while insider selling seems to have no “predictive” ability. Peter Lynch in his book One Up On Wall Street also talks about the importance of tracking insider buying activity and says when insiders are selling stocks of their companies there could be several motivations behind these transactions but when they are buying, you should pay attention since it usually means the stock will go up. We talked in detail about Peter Lynch’s thoughts on insider buying and selling in our article titled Underperforming Stocks Insiders are Buying.

Outsiders Can Make "Abnormal Profits" by Mimicking Insider Buying

Lakonishok and Lee’s research paper also talks about several studies that have already shown why and how insider buying is related with stock gains. For example, the paper mentioned Bettis, Vickrey, and Vickrey (1997), which concluded that outsiders can make “abnormal profits, net of transaction costs, by analyzing publicly available information about large insider transactions by top executives.” Lakonishok and Lee’s research paper also highlights that insiders are contrarians and buy value stocks that have performed well in the past. They also buy small-cap stocks with better growth prospects and past performance.

Small-Cap Insider Buying is More Important Than Large-Caps

However, one of the most important findings of the research paper is that market often “underreacts” to insider purchases and there has been no evidence that insider buying is directly linked with stock returns in the short term (the emphasis is on short term). However, for long-term investors, insider buying activity is a treasure trove which can also be used to “time the market.”
