Stock index futures were little changed on Friday, a day after equities hit a new 29-month high, as investors awaited a key reading on economic growth.

U.S. gross domestic product, due at 8:30 a.m. EST (1330 GMT), is seen having risen 3.5 percent in the fourth quarter, more growth than the previous quarter but not enough to significantly lower severe unemployment.

Ford Motor Co fell 6.3 percent to $17.60 in premarket trading after it reported quarterly earnings. Dow component Chevron Corp is on tap later in the morning.

Strong corporate results have contributed to the market's recent gains, but further advances may be harder to achieve.

S&P 500 futures rose 0.1 point and were even with fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 11 points, and Nasdaq 100 futures rose 2.75 points.

The S&P has risen 2 percent since the start of the earnings season, and various technical measures indicated the market may be overstretched.

The Dow and the S&P have struggled to advance past major technical levels -- the 12,000 mark for the Dow and 1,300 for the S&P. Still the Dow was on track to notch its ninth straight week of gains.

Late Thursday, Dow component Microsoft Corp posted a small dip in quarterly profit, rekindling fears that the popularity of mobile gadgets could erode its main PC-focused business. Still, the stock edged up 0.2 percent to $28.93 premarket. Inc's revenues missed expectations late Thursday. Shares of the online retailer fell 8.2 percent to $169.30 premarket.

SanDisk Corp's full-year revenue outlook topped estimates, but its fourth-quarter margins disappointed.
