Anyone interested in Alector, Inc. (NASDAQ:ALEC) should probably be aware that the Co-Founder, Arnon Rosenthal, recently divested US$172k worth of shares in the company, at an average price of US$1.97 each. On the bright side, that sale was only 1.5% of their holding, so we doubt it's very meaningful, on its own.

Alector Insider Transactions Over The Last Year

In fact, the recent sale by Co-Founder Arnon Rosenthal was not their only sale of Alector shares this year. They previously made an even bigger sale of -US$174k worth of shares at a price of US$2.12 per share. While we don't usually like to see insider selling, it's more concerning if the sales take place at a lower price. The silver lining is that this sell-down took place above the latest price (US$1.64). So it is hard to draw any strong conclusion from it.

Insiders in Alector didn't buy any shares in the last year. The chart below shows insider transactions (by companies and individuals) over the last year. If you want to know exactly who sold, for how much, and when, simply click on the graph below!

Does Alector Boast High Insider Ownership?

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. A high insider ownership often makes company leadership more mindful of shareholder interests. It appears that Alector insiders own 6.2% of the company, worth about US$11m. We've certainly seen higher levels of insider ownership elsewhere, but these holdings are enough to suggest alignment between insiders and the other shareholders.

What Might The Insider Transactions At Alector Tell Us?

Insiders sold stock recently, but they haven't been buying. And even if we look at the last year, we didn't see any purchases. Insider ownership isn't particularly high, so this analysis makes us cautious about the company. So we'd only buy after careful consideration. So while it's helpful to know what insiders are doing in terms of buying or selling, it's also helpful to know the risks that a particular company is facing.
