Tesoro (TSO) +1% premarket on top of yesterday's 9.5% gain after its bargain basement purchase of BP's California refinery. Oppenheimer raises its price target to $50 from $30 based on the deal, which it believes will boost TSO's competitive position as well as its operating and financial results and valuation.
