NEW YORK, Feb 25 (Reuters) - U.S. stock index futures edged lower on Tuesday, with investors finding few reasons to buy following a rally that took the S&P 500 to an all-time intraday high.
* Monday's advance to record levels fully erased the S&P's biggest pullback in more than a year and raised new questions about what catalysts will drive shares decisively higher from here. Despite Monday's climb, Wall Street ended off its highs and the S&P failed to close at a record.
* While the market's upward trend is still viewed as intact, valuation concerns have been raised following a string of economic data that has come in below forecasts. While many analysts pin the weakness to harsh winter weather rather than weakening fundamentals, trading are looking for evidence the market's levels are justified.
* Market participants will be closely monitoring February consumer confidence data, due out at 10:00 a.m. EST (1500 GMT), as well as a read on home prices with December CaseShiller data at 8:30 a.m. Confidence is seen dipping slightly from the prior month, while home prices are seen rising 0.6 percent.
