Take a look at the schedule for keynote speeches. Related stocks will probably get run up beforehand (CSCO, CA, EMC, NTAP .....) I feel for anyone who came into this week with a short position in any of these stocks. Going long some of the favorites right at or before the open would have been a good play. http://www.interop.com/news/lasvegas2003/index.php?d=keynotes&s=default
