Bliss, I must disagree. MSFT has a greater tendency to drop after earnings and upside is limited in the days following an announcement that does not disappoint. Specifically, look at 7/18 '03, 10/23 '03, 1/23 '04 (although it didn't drop immediately - it went up for a day before dropping for several) and 5/5 '04. On all other earnings announcements in the last 2 years, there wasn't much move to the upside in the days immediately following the announcement. Therefore, IMO, the greater risk is to the downside.
