Daily MA(50) is at $13.02, break over it has resulted in recent run up. Next target is MA(200) at $15.19 which reinforces your "above 15" idea. There is fairly heavy resistance between $14.50 and $15.
Weekly MA(50) is at $16.02 which sets up a secondary target once past $15. The weekly MA(200) is at $9.06, and not a factor at this point.
RSI for both weekly and Daily is neutral so the good news is that CORT has not been overbought during this run up. There is room run to run if buyers show up.
P&F, no time frame, is saying bullish price target is $17.50.
