Oil Refiners Take It On The Chin

 | Aug 21, 2014 11:55AM ET

The important oil-refinery sector is coming under selling pressure today. Leading oil-refinery stocks such as Tesoro Corporation (NYSE:TSO), Phillips 66 (NYSE:PSX), Marathon Petroleum Corporation (NYSE:MPC) and Western Refining (NYSE:WNR) have all declined since the start of the trading session. Day traders should watch Tesoro's stock around the $63.15 level, which is an area where the stock should stage an intra-day bounce.
