They are Priceline, Apple and Gap. This month alone, five Priceline executives have sold 16.7 million shares at a value of nearly $11 million dollars. And more than 83 million shares were sold by Priceline insiders in February.

And the phenomenon isn’t isolated to Priceline. Apple CEO Tim Cook as well as other top executives at Apple have been selling lately. The same is true of Gap .
