U.S. stock futures fell on Tuesday, suggesting a weaker start on Wall Street, after a disappointing outlook from cell phone microchip maker Texas Instruments Inc. and weaker-than-expected sales from Kraft Foods Inc. renewed concern about company profits.

With the added anxiety of Federal Reserve policy makers meeting about interest rates, investors appeared set to focus more on disappointments from Texas Instruments and Kraft than the flow of stronger-than-expected corporate earnings.

"We've also had a very, very good run, and we've been in very overbought conditions," said Bruce Zaro, chief technical strategist at Delta Global Advisors in Plymouth, Massachusetts. "The earnings trend in general is very strong, but you're always going to have disappointments."

U.S. stocks had rallied on Monday, with the Dow industrials closing at another record high.

Standard & Poor's 500 futures were down 1.2 points, below fair value, a mathematical formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.

Dow Jones industrial average futures were down 1 point, and Nasdaq 100 futures were down 0.25 point.

Shares of TI fell 1 percent in early electronic composite trading to $31.55 as the world's biggest maker of chips for cell phones forecast fourth-quarter revenue below average Wall Street estimates.

Shares of Kraft slid 4.4 percent to $34.69 in electronic trading before the bell after the food company posted lower-than-expected sales.

Investors expect the Fed, which begins a two-day policy meeting on Tuesday, to leave interest rates unchanged again, but they will scour the Fed's statement on Wednesday for signs of the outlook for rates.

Also in earnings news, DuPont Co., the No. 2 U.S. chemicals maker and a Dow component, posted a higher-than-expected quarterly profit against a loss a year earlier. Shares of the company rose 2.4 percent to $46.55 before the bell.

Online retailer Amazon.com is also due to report results after the close.
