NEW YORK, Sept 28 (Reuters) - U.S. stock index futures edged higher on Tuesday as traders looked ahead to key economic data in another test for the improving recovery theory that has driven up stocks this month.
Signs the economy is on firmer footing have driven gains of about 9 percent in September. Fresh indicators for the economy will be the S&P Case/Shiller Home Price Index and the Conference Board's monthly consumer confidence data later in the day.
"The market mover today will be the consumer confidence," said Peter Cardillo, chief market economist at Avalon Partners in New York. "A number there that is not going to show that the mood of the consumer is eroding further I think could probably propel stocks a bit higher today."
S&P 500 futures <SPc1> rose 0.1 point 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 <DJc1> gained 33 points, and Nasdaq 100 futures <NDc1> added 7 points.
The S&P 500 blew past a strong technical resistance level at 1,130 last week. Resistance is seen at about 1,173. The index closed at 1,142.16 on Monday.
The S&P Case/Shiller Home Price Index for July is due at 9 a.m. EDT (13:00 GMT) and is expected to show a decline of 0.1 percent versus a gain of 0.3 percent in June. The Conference Board's consumer confidence report is expected an hour later and is seen falling to 52.5 from 53.5, according to a Reuters poll. For details, see [
]Cardillo said he expected the September rally to continue through the end of the month, helped by end-of-quarter portfolio adjustments. "I think September will go out like a lion", he said.
European shares were slightly lower in early trade after dropping about 1 percent on persistent worries over sovereign debt levels in euro zone countries. The Nikkei 225 index closed down 1.1 percent as the deadline passed for dividends for the financial first half year.
Concerns over euro zone debt remained present and have weighed on equities all year. Standard & Poor's warned Tuesday it may cut Ireland's credit rating again due to the rising cost of recapitalizing nationalized Anglo Irish Bank Corp Plc [

Options investors seemed to be more concerned about current market conditions. Larry McMillan, president of McMillan Analysis Corp, said extreme overbought conditions were seen in the "term structure" of VIX futures. (Reporting by Edward Krudy; editing by Jeffrey Benkoe)
