My options screener is fairly quiet on the call side today, though it has picked up activity in Xerox (XRX). Nearly 7,000 May 18 XRX calls have traded vs open interest of 3786. Recent chatter on the street includes Buffett's Berkshire Hathaway (BRK/A) taking a stake in XRX. I have no confirmation. This is not a recommendation, but an FYI.
