Why not? Do you expect every trade to be successful? you must have a contingency if the trade goes against you. Hopefully, more trades go your way and those that go against you the damage is limited with such stops. Just took the bucker discount on COO and reestablished the position at $44.35. Also jumped back on the bu$$ here at $30.79, it seems to getting back its oomph. Got JCOM off here at $24.50 for another $.39. Not willing to take out $25 so far.
