We talked about Crocs (CROX) during yesterday's MidnightTrader Pro webinar. Another great quarter and another slam dunk for an after-hours buy. We know from historical reactions - as reported in the Earnings Notebook coverage - that this stock consistently adds significantly to gains the next day following earnings related after-hours gains.

After the close yesterday, Crocs (CROX) reported Q1 revs of $198.5 mln, ahead of the Thomson First Call consensus of $197 mln. Non-GAAP EPS was $0.09 per share, a penny shy of the Street view.

For the year, the company expects revenue growth between 15% and 20% over 2007 levels. Ex a charge, EPS is seen in the range of $1.70 to $1.80 per share. The Street is at 19% revenue growth and earnings of $1.60 per share.

For Q2, the company guided for revenue to increase about 10% to 15% over Q2 last year. Ex a charge, EPS is seen in the range of $0.45 to $0.50 per share. The Street is at 12% revenue growth and EPS of $0.43 per share.

All looked good here last night and still does ahead of the open. Now the question is how far CROX will rise today. Again, using history as a guide, traders can expect a 10-12% additional gain in today's regular session from the after-hours close. If you let it run, you might consider a tight stop to pretect these lofty gains.
