It's a buy above 28.53

NLS has pushed against the .618 Fib retracement from the all-time high to the all-time low. It is also making a giant 15-year cup with handle potentially as well. Look for it to clear 28.53, restest and resume higher to buy in. It is forming a short-term bull flag as others have pointed out, which could be the catalyst that pushes it over 28.52.
