Andrea, here's an update: I took your advice and it worked out pretty good. I got into MSFT at $215.76 on Thursday morning just after the market opened. Then BAM... the market tumbled. I did not get out at a controlled loss like I should have and saw it plummet to even further losses. I decided to not be a day trader for the day and kept my position and went golfing. BTW, I never do that.
I came back from my round of golf and it had actually recovered slightly but I had to hold my position overnight which makes me very uncomfortable. Then today MSFT open higher then crashed again. I decided to have lunch with my parents. When I came back MSFT had risen to the levels that I bought it at Thursday morning and actually made $15. I know its not a huge gain but I think of it avoiding a huge loss.
Thanks for the advice to once and awhile chill out...
