The New York Stock Exchange said it is reviewing trades in 148 symbols after “unusual activity,” Reuters reports.

“I think that has disrupted all the normal activities — stocks are moving all over the place, they are weird, they are trading like millions of shares, 100 shares at a time, so something went haywire somewhere,” said Stephen Massocca, managing director at Wedbush Morgan, in the story.

“It appears to be dozens if not hundreds of stocks that have gone extremely high volume and extremely rapid movement,” added Joe Saluzzi, co-manager of trading at Themis Trading.
