be careful if you are short. There is a some level of uncertainty at this point but once that clears up, which could come up any time with news, upgrade, analysis, earning, guidance, MM could reach news highs very quickly. The reward for a short position at this point is dead money and very risky.
You could play it either/both ways. Buy the big dips, short the pops. It has been stuck in a range since earnings. I have stayed trading the long side because I believe the longer term will be a strong up-trend. I wouldn't want to get caught short on a real move.
