U.S. markets will be closed on Thursday and the session will end at 1pm ET in observance of the Thanksgiving holiday, but headlines will be fast and furious for the retailers and energy patch with Black Friday and the key OPEC meeting also on Friday. Black Friday increasingly lends to choppy retail trading as analysts and the media pick through all the data pouring in from the malls and online purchases. Longer-term expectations are quite good for holiday 2014, particularly activewear like Footlocker, Nike and consumer electronics like Best Buy. A slew of manufacturing data is expected, including the all-important GDP number on Wednesday, as well as manufacturing, housing and consumer numbers. Only eight S&P 500 companies report, including Campbell's, Hormel, Pall Corp, Tiffany, Analog Devices, Hewlett-Packard and Deere, but traders will be busy with the commodity trade, especially crude and gold.
