It is not wrong to add to your winning position. It depends on your goal and strategy.
This is not a day-trade stock. I treat her as my summer-vocation-fund(SVF). Buy and accept her dancing style. The company's FA is very strong and aslo well beaten in the past year.
If you just want to play with her in short-term, you can consider to dump some your position. Her next test level is $5.
If you target big gain and can accept her volatility in long term (several months), you can add some.
I never buy ONE stock with more than 10% of my total portfolio.
