U.S. stock futures traded slightly lower Tuesday following comments on interest rates from Federal Reserve Vice Chairman Stanley Fischer.

S&P 500 futures fell 0.06%, Dow Jones Industrial Average futures slipped 0.03%, while Nasdaq futures lost 0.23%.

Fischer said the U.S. labor market is "very close to full employment" in an interview with Bloomberg Television Tuesday and added he can't say whether the next interest rate increase would be "one and done."

"We can choose the pace. But we choose the pace on the basis of data that are coming in," Fischer said in the interview.

"So I don't think we know at the time we start whether it's one and done or several. It depends entirely on what happens in the economy," Fischer said.

At a speech last week in Jackson Hole, Wyo., Fed Chair Janet Yellen said the argument for a rate hike "has strengthened in recent months." 

The S&P CoreLogic Case-Shiller U.S. National Home Price index rose 5.1% year over year in June, in line with May's increase.
