Housing market in focus on Wall Street

U.S. stock index futures pointed to a higher Wall Street open on Wednesday, ahead of further housing market indicators.

August new home sales figures are due, along with the weekly mortgage application numbers. This comes after the National Association of Realtors reported on Monday that sales of previously owned homes declined 1.8 percent last month.

Wednesday will also bring a five-year Treasury auction and speeches from more members of the Federal Open Market Committee. These include the Chicago Federal Reserve's Charles Evans, who will speak at a labor market conference in Washington.

Evans is dovish on monetary stimulus. "Our sense is that dovish Fed Presidents may well utilize easing inflationary pressures as an argument to highlight downside risks from here," said Derek Halpenny of Bank of Tokyo-Mitsubishi in a research note on Wednesday.

Accenture will post earnings before Wall Street opens on Wednesday, followed by KB Home and Vail Resorts after markets close.

Other companies to watch include Home Depot, after the Wall Street Journal reported that the data breach at the home improvement retailer had led to fraudulent transactions across the U.S.

Plus, stocks of Citizens Financial Group—the spin-off the U.K.'s Royal Bank of Scotland—will be worth watching, after pricing at $21.50 per share in its market debut on Tuesday.

Market sentiment remains subdued after the U.S. and its Arab allies (Saudi Arabia, Qatar, Jordan, Bahrain and the United Arab Emirate) bombed militant groups in Syria for the first time this week, killing scores of Islamic State fighters.
