Sheldon has always been a loose canon and if you had looked at pnp holdings you would see selling in most of them. pnp has to come up with money that's it so no,,,,sheldon doesnt know something negative re ptk and is selling because of it. Look at it this way chance to pick up cheap paper in ptk . Nice to see when he comes in-buying, well now he is being forced to sell and you have the chance to buy..imo cheap
