Destruction of oil infrastructure "would totally change the game" of crude's downward price action if the U.S.-Iran War escalates, says Rob Thummel. He sees strength in high dividend oil stocks and has Cheniere (LNG), Exxon Mobil (XOM), and Williams Companies (WMB) as top picks. Joe Rinaldi says investors "missed the boat" on oil stocks and would not buy at current prices, with one exception: BP PLC (BP).
