I saw it spike up at 10:02 and tried to sell my position, but I immediately noticed that the Bid/Ask hadn't moved up with the trade (123 shares at 123.144 !!!???). Another electronic screw up due to machine algorithms? There were some other anomalies during the day also. Also another ETF I have, IAU had similar problems.
Funny that the trade for TIP went on the record as an all time high though. This market is really screwed up and getting worse, with the SEC doing nothing about it, apparently. I'm sure we'll have another flash crash soon.
