Kind of along those lines, I don't think either the company or Icahn want the SD warrants to get exercised and have to increase the outstanding shares. Icahn ran an options desk when he was younger so he's very familiar with all this stuff. And he watches every penny. (The doc about him is pretty good) His kid is sharp also.
So on the final couple of days before the warrants expire, if the stock is within a few dollars of the strike price of those warrants, Icahn could by the Oct deep in-the-money Calls and then short the stock with a few massive equivalent sell orders large enough to drive the price down below the strike price of the warrants. And then exercise the options the next day to cover the short.
There's already a surprising amount of open interest in the Oct in-the-money Calls, especially when compared to Aug Calls. Could be total coincidence, no kidding.
Who knows, but it wouldn't surprise me if he's contemplating something like that.
