Dec 7 (Reuters) - U.S. stock index futures rose for the third straight day, as investors continued to bet on a post-election rally that has powered major Wall Street indexes to a series of record highs.
* President-elect Donald Trump's proposals to boost infrastructure spending and simplify regulations have boosted financials and industrial stocks since the election on Nov.8.
* Dow futures have marked losses only four times and have risen 6.9 percent over the past month.
* A spate of strong economic data and robust third-quarter earnings that put an end to a profit recession have also supported the rally.
* Wall Street ended higher on Tuesday, with the Dow closing at a record high, buoyed by gains in banks and telecom stocks AT&T and Verizon.
* While an interest rate hike at the Federal Reserve's meeting next week is a foregone conclusion with traders pricing in a whopping 92 percent chance of an increase, investors are on the lookout for how the central bank views Trump's pro-growth policies and whether that could lead to more aggressive rate hikes next year.
* The Fed has entered a self-imposed blackout period until its news conference on Dec.14.
* Among stocks, Western Digital rose 5.4 percent to $67.30 in light premarket trading after the data storage maker raised its second-quarter profit and revenue forecasts.
* Bluebird Bio fell 2.5 percent to $77 after the drugmaker priced a stock offering at a 3.7 percent discount to the stock's Tuesday close.
* Restaurant and arcade chain operator Dave & Buster's soared 13.5 percent to $54.50 after the company posted upbeat results for its latest quarter and raised its full-year revenue forecast.
* No key economic data is scheduled for Wednesday.
