Options are just stock price probabilities based upon a price dispersion model so your question seems circular. My post is just observation of how one biggish shareholder is reacting to stock movement, stochastic or otherwise. I do make the assumption that he knows what he is doing as he has done for the past 3 options cycles. He votes with his money that the move is stochastic and sold covered calls. I went along and sold some CCs too. I am sure he got paid more.
