NEW YORK, Dec 15 (Reuters) - U.S. stock index futures dipped on Wednesday after a warning for Spain about its credit rating, rekindling fears about euro-zone debt.

Credit rating agency Moody's said it could downgrade Spain's debt and that it was concerned about the country's high funding needs. For details, see [ID:nLDE6BE110]

"The market has been tackling the euro-zone issue since April, and we all know that these countries are more credit-worthy than what these ratings say," said Jack DeGan, chief investment officer at Harbor Advisory Corp in Portsmouth, New Hampshire.

"But with the S&P already up so much and the latest outlook from the Fed, we just don't have a catalyst to move the market higher this morning."

S&P 500 futures were down 3.5 points and 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 fell 19 points, while Nasdaq 100 futures dipped 7 points.
