GE is flat at $17.04 and March 17.5 calls are busy Monday. More than 43K traded and some of the action might be closing. Open interest is 181.4K and the biggest OI position of any GE contract. However, the top trade is a block of 2738 contracts at 17 cents on the ISE, which traded just after the opening bell and appears to be an opening customer buyer, according to ISEE data. The interest in GE calls comes on news the company is selling its electrostatic precipitator and emissions monitoring businesses to McDermott and the day before it presents at a Goldman Sachs Industrial Unscripted Conference. GE is also presenting at a Jefferies Global Clean Tech Conference tomorrow and Wednesday.
