Note: these are monthly candles and the scale is logarithmic. UNH has been trading pretty consistently within a parallel channel on the logarithmic scale chart since 2009. UNH is now at the upper bound of that channel. There were a few months in 2011 where the stock broke out and managed to stay above the top of the channel before it came back and has traded inside there ever since. Looking at those months, the stock managed to go about 10% higher in price than the upper bound of the channel. Considering current market conditions, UNH may break out of this channel again, and I suspect it would have about 10% upside if it did. If this break out sustains, look to see the top of this channel act as support going forward. There is also the possibility that it could pull back and continue trading within the channel.
