Many bulls are blaming a lot of yesterday’s problem on the Dow’s computer glitch. That’s so ridiculous I won’t even bother to shoot apart those assertions. Barry Ritholtz did a fantastic job on his site so I’ll just link to that and leave it up to you to decide.  I was also impressed with Ticker Sense and their reconstruction of what the index probably-shoulda-coulda-woulda looked like and you can evaluate that here.  The bulls may want to cry foul that the market would have stabilized if not for the glitch but there is no evidence for that. The bears may want to say it would have gotten worse if the trades had been reported properly prior to the glitch but there is no evidence for that either. We trade on the information we have at that moment whether it is accurate or not. It’s unfortunate that the selling was so heavy that the massively sophisticated computers could not handle the calculations and it’s critical that the exchanges learn how to improve on this situation. Just don’t bitch about the glitch!
