The Nasdaq has been a major laggard this week, dropping 3 percent as the S&P 500 fell less than 1 percent and the Dow Jones industrial average has been nearly flat. And at this point, David Seaburg, the head of equity sales trading at Cowen & Co., says he doesn't know just what will end the selling.
"We are definitely seeing people sell a lot of names here. It is institutional selling on the desk," Seasburg said on Thursday's episode of "Futures Now." "I don't know who the incremental buyer is going to be when things really do start to pick up again."
The problem started when investors began to flee from high-beta momentum stocks.
"You're seeing a lot of the bigger high-beta names really being pushed down," Seaburg said. "We've seen a rotation out of the high-beta names into the high-value names, and it's been a clear rotation on our desk."
Then the results and guidance from Accenture, a major consulting and IT company, changed the outlook for larger tech companies. While the earnings results were weak, Accenture increased guidance, which some saw as a warning sign.
