Nearest Resistance: $13.50 Nearest Support: $12 Catalyst: T-Mobile or Sprint Merger The drama continues to spur trading in MetroPCS ( PCS) this week. For those who weren't following the story, MetroPCS is in talks with T-Mobile about a merger deal right now. The move sparked a big rally in shares of PCS earlier in the week that's mostly settled down at this point -- but news that Sprint ( S) could throw an offer on the table too makes things a little more interesting. I like PCS a lot -- the firm has a big base in the flat-price cellular business that was trading at a big discount. So last May, I put MetroPCS on my Rocket Stocks list, saying that an acquisition was the likeliest path to upside for the firm. The rally that shares have undertaken in the last several months has borne that out. At this point, though, all of the eyes on PCS have eroded away much of its upside potential. I'd recommend looking elsewhere for a better risk/reward tradeoff.
