Stocks dropped sharply on Thursday, with the Dow losing over 170 points and extending losses for a third session, after disappointing U.S. and Chinese manufacturing data sparked concerns for global growth.
Wall Street's drop stems largely from worries about China, "as far as economic growth is concerned, and the potential for it to lead to pressure on loans they have outstanding; that's weighing on the market," said Robert Pavlik, chief market strategist at Banyan Partners.
And, "earnings season is not proving all that much help right now. It's not terrible, but it's not outstanding. People are looking for this long overdue correction, so this is early kindling to that potential fire," Pavlik added.
