IndyMac (IMB)

Just a quick note about IMB. Today nearly 80,000 May25 calls traded. More than 60,000 of that volume was written vs open interest of just 5885. Is this a prelude to a big slump ahead? I don't think so, at least according to this options activity. Bear in mind, IMB trades ex-dividend tomorrow; so it appears today's activity was market maker to market maker fun and games.
