Analyst: Not much change in sentiment after presidential debate

U.S. stock futures on Thursday pointed to a muted open, as traders braced for a raft of economic data and largely shrugged off the third and final presidential debate.

Investors are waiting for readings on jobless claims, existing-home sales and a key Philly Fed index.

S&P 500 futures inched up by 1.90 points, or 0.1%, to 2,140, while Dow Jones Industrial Average futures edged higher by 22 points, or 0.1%, to 18,147.

Nasdaq-100 futures tacked on 6 points, or 0.1%, to 4,836.25.

"Last night's final debate of the U.S. presidential campaign appears to have passed off without initiating any significant change in sentiment for the electorate," said Tony Cross, a market analyst for TopTradr, in a note.

"Hillary Clinton remains in the lead, according to the polls, and the fortunes of USD/MXN certainly play this out with the pair briefly testing territory as low as 18.50," Cross added.

The Mexican peso was lower against the dollar, after earlier rising to its highest against the buck in six weeks (http://www.marketwatch.com/story/mexican-peso-rises-to-6-week-high-against-dollar-after-debate-then-gives-up-gain-2016-10-20). The currency is seen as a good way to gauge (http://www.marketwatch.com/story/show-what-you-know-about-tech-stocks-ailing-banks-and-a-key-trump-barometer-2016-10-10) Donald Trump's chances in the race for the White House, and some analysts had argued its brief rally was a sign the Republican nominee hadn't fared as well as his Democratic opponent.

Attention now turns to a news conference featuring ECB chief Mario Draghi.
