NEW YORK, March 7 (Reuters) - U.S. stock index futures edged up on Thursday, suggesting investors will attempt to hold on to recent gains, with data on the jobs market due to be released later in the morning.

The Dow surged to record levels for a second day on Wednesday, while the S&P 500 inched up to just 1.5 percent below its own record close.

A strengthening economy and loose monetary policy by central banks around the world have pushed U.S. equity markets higher this year. While some expect the market will ease off its current lofty levels, so far, dips have been short-lived as investors look for an opportunity to buy.

A report on initial jobless claims due at 8:30 am ET (1300 GMT) is expected to show the number of people filing for unemployment benefits rose slightly to 355,000 last week.

Investor attention will remain on the labor market ahead of Friday's non-farm payroll report, which is expected to show the economy added 160,000 jobs in February. Though high unemployment has been a weak spot of the economic recovery, the labor market is seen to be healing slowly.

S&P 500 futures rose 0.5 point and were slightly below 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 gained 14 points, and Nasdaq 100 futures added 3.75 points.

Network equipment maker Ciena jumped 10.7 percent to $16.54 after reporting first-quarter results.
