Resistance:- I think there is at least upside to $24. - Above that, I think there could be strong resistance in the $26-$26.25 area.- At this point, I would limit the most aggressive bullish outlook to $28.00. Trade Plan:- GMS is not a sexy name, but has some upside in the short-term.- I am putting an order at $20 with the target of $26 and a stop around $16. GMS Weekly Chart(click to enlarge)
