Hovering in the 12,800 to the 13,000 range, the Dow Jones is often a barometer of the economy. As the United States economy unfolds in 2012, it will have to overcome several hurdles before the Dow Jones can possibly stay above 13,000 for an extended period of time.  Consumer data, unemployment rates, the housing and the effects of the end of the Iraq War are all expected to have a strong influence over the profits reaped from the Dow Jones this year.
