Only Mirati has seen intensive insider buying during the past 30 days.


There have been three different insiders buying Mirati and there have not been any insiders selling Mirati during the last 30 days. Two of these three insiders increased their holdings by more than 10%.

There are three analyst buy ratings, zero neutral ratings, and zero sell ratings with an average price target of $21.08. Mirati does not have any near-term data readouts scheduled. I believe the stock could be a good long-term investment based on the intensive insider buying.
