AMAT reports earnings on Wednesday after the close. The stock is trading up $1.25 so far today and the Mar $62.50C has traded as high as $4.10, up about 30% from yesterday's entry. (Personal entries could be better or worse.) The choice to hold through earnings is always a coin flip, so that is left to the individual trader. Anyone expecting to exit before earnings might want to place a mental stop at break-even, essentially reducing risk on this trade to zero.
