I just added a little to my short position. Most of my short is from higher prices, even after taking profits last week on shorts from higher levels. It may be that on each bounce longs bail out sooner. The question is whether in the short term big owners try to boost up the stock price or just sell. I don't think anyone can be sure of that. I think if we go over 140 in this atmosphere, the selling will come in.
I meant to add something I found interesting. Earlier this week, some of what I re-shorted was filled from 5 different sources of shares. This wasn't a large short transaction. I shorted my shares in different trades. This was a 100 share trade and it was filled with 17 shares from one source, 10 from another, etc..
