NEW YORK (Reuters) - U.S. stock index futures declined on Wednesday, putting the S&P 500 on track for a second straight decline, ahead of data on the labor market and services sector.
* The ADP National Employment Report for February is due at 8:15 a.m. and will be eyed for signs of strength in the labor market. Expectations call for private employers to add 220,000 jobs versus the 213,000 recorded in January.
* Shortly after the opening bell, two readings on the services sector are expected with the final February reading of financial data firm Markit's Purchasing Managers Index at 9:45 a.m.. The Institute for Supply Management's gauge on the services sector in February is scheduled for a 10 a.m. release.
* Investors will deal with a flurry of economic data for the rest of the week, culminating with the Labor Department's February payrolls report, which will be used to help gauge the timing of an expected interest rate hike from the U.S. Federal Reserve.
* Soft auto sales and weakness in technology stocks sent Wall Street lower in the prior session, pulling the Dow and S&P 500 from record levels and the Nasdaq below the 5,000 mark.
* Honeywell
* Bob Evans Farms
* Alcoa
* European shares were flat as stocks retreated after a weaker-than-expected final February Composite Purchasing Managers' Index reading from Markit.
* Asian shares fell as investors grew cautious before upcoming central bank meetings and U.S. jobs data as Japan's Nikkei share average dropped to a one-week low, although China stocks rebounded in volatile trade.
Futures snapshot at 7:28 a.m.:
* S&P 500 e-minis
* Nasdaq 100 e-minis
* Dow e-minis <1YMc1> were down 47 points, or 0.26 percent, with 15,684 contracts changing hands.
