Wall St. to open flat with Fed statement on tap

NEW YORK (Reuters) - U.S. stocks were poised for a flat open on Wednesday, after a three-day winning streak for the S&P 500 index and ahead of a monetary policy announcement by the Federal Reserve.

The Fed is widely expected to announce another $10 billion cut to its monthly bond purchases as it wraps up a two-day policy meeting at 2:00 p.m. (1800 GMT), but is likely to make few, if any, other concrete policy moves. Investors will be attuned to whether officials may tip their hand on longer-term plans for interest rates.

The benchmark S&P index has risen 0.6 percent over the last three days, as investors largely shrugged off mounting tensions in Iraq amid a flurry of merger and acquisition activity and better-than-anticipated manufacturing data.

Saudi Arabia said on Wednesday Iraq faced the threat of full-scale civil war with grave consequences for the wider region and, in an apparent message to arch rival Iran, warned against outside powers intervening in the conflict.

S&P 500 e-mini futures ESc2 were off 0.25 points and fair value - a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract - indicated a flat open. Dow Jones industrial average e-mini futures 1YMc2 fell 6 points and Nasdaq 100 e-mini futures NQc2 added 4 points.
