(CNBC) — U.S. equities closed sharply lower on Monday, with financials and health care lagging, as market watchers kept a close eye on a key OPEC meeting and looked ahead to a U.S. presidential debate.
"The market has basically priced in a Hillary Clinton victory," said Randy Warren, chief investment officer at Warren Financial Service.

The Dow Jones industrial average fell more than 160 points, with Goldman Sachs contributing the most losses.
