Insiders Could Have Profited By Holding onto Alector Shares Despite 10% Drop

Alector, Inc.'s (NASDAQ:ALEC) stock price has dropped 10% in the previous week, but insiders who sold US$1.1m in stock over the past year have had less luck. The average selling price of US$2.60 is still lower than the current share price, or in other words, insiders would have been better off holding on to their shares.

While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, logic dictates you should pay some attention to whether insiders are buying or selling shares.

The Last 12 Months Of Insider Transactions At Alector

Over the last year, we can see that the biggest insider sale was by the Director & Member of Scientific Advisory Board, Richard Scheller, for US$228k worth of shares, at about US$5.16 per share. While insider selling is a negative, to us, it is more negative if the shares are sold at a lower price. It's of some comfort that this sale was conducted at a price well above the current share price, which is US$1.46. So it may not shed much light on insider confidence at current levels.

Alector insiders didn't buy any shares over the last year. You can see a visual depiction of insider transactions (by companies and individuals) over the last 12 months, below. If you want to know exactly who sold, for how much, and when, simply click on the graph below!
