Report on CNBC that there were a lot of ordering problems with a dozen or so stocks and the electronic trading systems. There were fairly large gyrations in those stocks. They mentioned a ticker symbol NUS as one of them and I'm wondering if that didn't get confused with NVS of Novartis. Average 10 day volume has been 2.6M but today I see 5.7M shares have been traded on no news. I'm guessing this was the problem.
