INTC .. expecing a bounce sometime to 17.50 whether it be before earnings or after, I'd never commit to holding anything through earnings, RIMM was just a 'stroke of luck'. DNA did great in anticiption and so did most everything else, but holding through is another ball game, especially if there is
a) too much pullback before the report (which made YHOO oversold)
b) too much upside before the report (DNA) which made DNA a target for pullback. So I would feel safe to trade these a lot before the report and would buy/ or short on the premarket following the report and/or the crap after any gap up.
