Alumis Insider Transactions Over The Last Year

Notably, that recent purchase by Alan Colowick is the biggest insider purchase of Alumis shares that we've seen in the last year. Even though the purchase was made at a significantly lower price than the recent price (US$10.05), we still think insider buying is a positive. Because the shares were purchased at a lower price, this particular buy doesn't tell us much about how insiders feel about the current share price.
