cover pressure to drive the price up.
But it is appropriate to recheck your HW's regularly to see if hold/buy/sell/short/cover are appropriate.
Also, please check your math. I agree it is a big ARB. According to this weekend's estimate, it will delist at at least 68 (and probably closer to 75 if it does 7M more) but remember to subtract the current price for the gain. People buying today are not buying at zero, or 5, but at a number over $30. (Estmate based upon 168M -100 strike plus about 7M more as the post holiday box office totals start to dwindle.)
