Cable TV stock Comcast ( CMCSA) is another name that's looking bullish in March. Like Sanofi, Comcast has seen its shares rally higher in an uptrending channel for the better part of the last year, but more recently it's an ascending triangle pattern in shares that's signaling a buy for this stock. The ascending triangle is a pattern that's formed by a horizontal resistance level to the upside and uptrending support below shares. Basically, as CMCSA bounces in between those two technically-significant price levels, it's getting squeezed closer and closer to a breakout above resistance at $41.75. When that happens, we've got a buy signal for shares. >>Less-Volatile Stocks for a Volatile World Shares are extremely close to pushing through resistance right now, indicating that traders had better be keeping a close eye on this entertainment stock this week. Look for confirmation before piling into shares.
