What this transaction means for investors

There are plenty of reasons an insider may choose to sell shares in a company. They can have nothing to do with their outlook for the share price. They may be forced to sell to pay a tax bill, as part of a divorce settlement, or as part of reasonable portfolio diversification.

There is only one reason an insider buys stock: they expect the price to go up.

That means Moore’s purchase of Corvus shares is a positive signal, but it should be tempered by the reality that the executive hasn’t previously bought stock in the company. Corvus does not have a policy requiring directors to buy shares; however, Moore is voting his feelings on the company by spending his own money. The fact that he received some stock options the same day suggests a positive outlook.

Studies show that insider buying is more predictive for future price gains than insider selling is for future price declines. The fact that Corvus shares have already advanced about 9% from Moore’s purchase price shows good timing.

Moderate insider selling like this should not be the only bullish signal an investor considers, but it’s a data point worth weighing as you look at Corvus Pharmaceuticals.
