Stocks suffered a dismal start to the month on Tuesday as conflicting polls bred uncertainty over the upcoming presidential election.
The S&P 500 was down 0.68%, the Dow Jones Industrial Average fell 0.58%, and the Nasdaq declined 0.69%. The S&P 500 has fallen for the past six sessions.
Conflicting polls created uncertainty over the outcome of the U.S. presidential election. An NBC/SurveyMonkey poll showed Democratic presidential candidate Hillary Clinton's 6-point lead remained after concerns over her emails were raised again on Friday. A separate ABC poll showed Republican presidential candidate Donald Trump with a 1-point lead. U.S. voters will head to the polls on Nov. 8.
"The reopening of the Clinton email investigation indeed raises the possibilities of a market re-enacting the scenario from the Nixon years, where uncertainties created an unstable market notwithstanding a solid economic environment," said Peter Cardillo, chief market economist at First Standard Financial. "While no one will be able to predict the outcome, one thing is certain: Uncertainties are the markets' worst enemy. In other words, it's time to be cautious."
Crude oil prices fell on Tuesday as worries over a deal among major oil-producing countries persisted. Goldman Sachs added to a chorus of concern on Monday evening after warning that prices could plummet if the Organization of Petroleum Exporting Countries fails to enact a production freeze agreement at a meeting in late November.
A deal looks more and more distant, analysts wrote in a note, with "weakening oil fundamentals warranting oil prices in the low [$40 a barrel range] in our view if OPEC is unable to deliver a convincing agreement."
West Texas Intermediate crude fell 0.08% to $47.42 a barrel on Tuesday.

Manufacturing activity in the U.S. in October rose at a faster pace than expected, according to the latest ISM Manufacturing Index. The measure increased to 51.9 last month from 51.5 in October.

August's number was also revised to show a smaller increase.

The Federal Open Market Committee convened on Tuesday morning to discuss monetary policy. The Federal Reserve's policy-making group will conclude the meeting on Wednesday afternoon with a statement, but no press conference is scheduled.
"While the market is widely anticipating the Fed to keep policy unchanged in Wednesday's announcement, the statement itself should hold plenty of clues as to the Fed's objective for rates at the final meeting of 2016," said Lindsey M. Piegza, chief economist at Stifel. "If it's anything like last year, and the Fed intends to follow through with a year-end hike, the language this month will no doubt provide specific guidance; reinforcing expectations for another increase come December."
