Today's Master the Trade setup is a long in the healthcare name UNH. When looking at a weekly chart, it is quite clear that the $30 level serves as significant resistance. Having displayed relative strength yesterday on an up day with volume associated, this stock seems ready to break above this level. In premarket action, UNH is trading near $29 and is worth a look today and over the next few trading sessions. Keep an eye on this group, as it will certainly be in play with the healthcare talks continuing in Washington.
