Transactions of insiders are usually a useful source of information when evaluating a stock. Insiders typically have a good understanding of the underlying business and buys are therefore often considered as positive signal. On the other hand, insider sales are not necessarily negative. There are many non-informative reasons to cash out. Maybe the insider needs some cash for personal expenditures or just wants to diversify his assets. This week’s AGNOSTIC Paper challenges this asymmetry and creatively shows that even those transactions convey important information…
- “Not sold” stocks from insider portfolios outperformed
- A portfolio of “not sold” stocks easily beat the US market
- “Not sold” stocks with momentum are even better
- Corporate insiders know more than institutional investors
