* Investors seek catalysts with indexes at record levels
* Dow on track for best two-week period since June 2012
* Textron to buy Beechcraft for $1.4 billion in cash
* Futures: Dow up 5 pts, S&P down 0.9 pt, Nasdaq down 0.25 pts
NEW YORK, Dec 27 (Reuters) - U.S. stock index futures were flat on Friday, with investors reluctant to make big bets after a rally that took major indexes repeatedly to all-time highs.
* Trading volume is expected to be light, as it has been all week. Many market participants are still out for the Christmas holiday, and there are few catalysts to pull traders into the market.
* Equities have been on a tear lately, with the Dow notching its sixth straight advance on Thursday, the longest daily streak for the blue chip average since March.
* Both the Dow and S&P 500 are on track for a second straight week of solid gains, with the S&P looking to post its best two-week period since July while the Dow posts its best two-week period since June 2012.
* While further gains may be difficult to come by, especially amid a dearth of trading catalysts, there will likely be a floor under equity prices for as long as the Federal Reserve continues its stimulus program.
S&P 500 futures dipped 0.9 point but remained 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 rose 5 points and Nasdaq 100 futures slipped 0.25 point.
* For the week, the Dow is up 1.6 percent, the S&P is up 1.3 percent and the Nasdaq is up 1.5 percent.
* The S&P 500 has soared 29.2 percent this year, largely due to the Fed's stimulus. The index is on track for its best year since 1997. The Dow has gained 25.8 percent in 2013 while the Nasdaq has jumped 38 percent.
* In company news, Textron Inc agreed to buy aircraft maker Beechcraft Corp for $1.4 billion in cash.
* General Motors Co's China joint venture will recall close to 1.5 million vehicles due to potential safety issues in one of the biggest recalls in the world's biggest autos market.
* Wall Street rose on Thursday, boosted as strong data about the holiday shopping season lifted retail stocks. The Dow rose to a record closing high for the sixth straight session while the S&P scored its fourth record close in a row.
