Dec 9 (Reuters) - U.S. stock index futures edged up on Friday, indicating that investors were still eager to buy into the post-election rally that has propelled a host of Wall Street indexes to record highs.
* The "Trump rally" has been running for the past month as investors bet President-elect Donald Trump's policies will boost economic growth and inflation.
* The three main U.S. indexes closed at record levels for the second day in a row on Thursday, while the small cap Russell 2000 and the Dow Transport hit all-time highs.
* Adding to the upbeat mood in the past weeks has been a spate of robust economic data, including on monthly hiring numbers, GDP growth and inflation, which have underscored the economy's strength.
* However, one spot of worry is valuations, with the S&P 500 is currently trading at about 17.5 times forward twelve-month earnings, above the 10-year median of nearly 15 times, according to Thomson Reuters StarMine.
* Data on tap for Friday is a preliminary reading of the consumer sentiment index for December, which is expected to hit 94.5 after rising to a 6-month high the previous month. The report is due at 10:00 a.m. ET (1500 GMT).
* The stock market rally's resilience will be put to test after the Federal Reserve's policy meeting next week, where traders see a 94 percent chance of the central bank raising interest rates.
* Among stocks, those of Restoration Hardware plunged 18.5 percent to $31.76 in thin premarket trading after the furniture retailer lowered its fourth-quarter profit forecast, citing slow sales in the holiday period.
* Wynn Resorts rose 4.7 percent to $95 after Macau, the world's biggest gambling hub, clarified it had not tightened daily cash withdrawal limits for Chinese gamblers.
* Biogen rose 3.3 percent to $299 after a study showed higher doses of the company's Alzheimer's drug appeared to reduce the risk of brain swelling.
