NEW YORK, Oct 30 (Reuters) - Wall Street was set for a slightly higher open on Wednesday, adding to fresh records scaled by the Dow and the S&P 500, amid sturdy results and on expectations the Federal Reserve will continue its stimulus efforts into next year.
Shares of General Motors Co rose 1.5 percent in premarket trading in the wake of better-than-expected quarterly profit due to strength in its core North American market and a smaller-than-anticipated loss in Europe.
The Federal Reserve is expected to maintain its massive bond-buying campaign when it concludes a two-day policy-making meeting on Wednesday, and may indicate that its stimulus measures will be extended into 2014 amid softer readings on the U.S. economy.
The ADP National Employment Report showed early Wednesday that U.S. private-sector employers added 130,000 jobs in October, fewer than economists expected. The market barely reacted to the data.
"Once again, the latest survey of the health of the national economy bears little impact on the outcome for Fed policy later in the day. The reading (on ADP) was light with blame likely falling at the door of Washington politicking," said Andrew Wilkinson, chief economic strategist at Miller Tabak & Co in New York.
S&P 500 futures rose 3.4 points and were above 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 46 points and Nasdaq 100 futures added 12 points.
On Tuesday, the Dow and S&P 500 ended at record highs after economic data supported views that the Federal Reserve would keep its stimulus intact for several months. Tuesday's rally brought the S&P 500's gain this year to 24.2 percent.
Shares of Yelp Inc fell nearly 10 percent in premarket trading a day after the business-search service firm reported a wider third-quarter loss.
LinkedIn Corp shares dropped 3 percent in premarket trading in the wake of the company's conservative forecast Tuesday for revenue for the rest of the year.
Companies due to report Wednesday include Comcast, Visa, Starbucks, MetLife and Kraft .
Corporate results have been sturdy so far in this earnings season, during which 296 companies, representing 66 percent of S&P 500's market capitalization, have reported.
"All of the 10 sectors have beaten their earnings-per-share expectations and the aggregate earnings surprise is 4.5 percent," said Jonathan Golub, chief U.S. market strategist at RBC Capital Markets in New York.
The U.S. central bank, which will announce its policy decision at 2:00 p.m. EDT (1800 GMT), has held interest rates near zero since late 2008 and has quadrupled the size of its balance sheet to more than $3.7 trillion through three rounds of bond buying. The purchases are aimed at holding down longer-term borrowing costs.
The Fed shocked markets in September by opting to maintain its bond-buying program, after raising expectations over the summer that it was ready to start scaling back the purchases. The central bank's caution has since been vindicated.
