Last up is mid-cap insurance firm Aspen Insurance Holdings ( AHL). Aspen has been locked in an uptrending channel for all of 2012, rallying higher in between well-defined trend line resistance and trend line support levels. Those boundaries make it significantly easier to spot the high-probability moves in this financial stock. Right now, AHL is sitting up near resistance, which makes another move lower look likely. After that, investors should be looking for an opportunity to buy on the bounce off of trendline support. If the stock's in an uptrend, why wait? Well, the best time to buy a stock that's in an uptrending channel comes at support -- it's the place where shares have the furthest to move back up to resistance (the top of the channel) and where they have the least distance to move through support. Since a breakdown below support means that the channel is broken, support is also a logical place to put a stop below to ensure minimal risk. The ideal AHL trade will take a little patience, but it should be rewarded in the end.
