BALTIMORE ( Stockpickr) -- Today's the first trading day of 2011 -- and you can bet that market participants are waiting with baited breath to see whether the New Year will start off on the right foot.Not surprisingly, light trading was the rule last week as traders took reprieves from the market to spend time with their families; as a result, market direction has been somewhat less convicted to end December. Today is the first time since Christmas that we'll get a reasonable glimpse at investor sentiment. All told, the S&P 500 gained 12.78% in 2010, a strong year by conventional standards. But nearly all of those gains came in the final quarter of the year as bulls struggled to take control of price action. With a bevy of economic data scheduled to be released this week, we should have a good opportunity for one side of the market to become dominant.
