US STOCKS SNAPSHOT-Dow, S&P 500 open up on data optimism

NEW YORK, Nov 2 (Reuters) - The Dow industrials and S&P 500 opened higher on Monday, as investors anticipated an improved domestic manufacturing sector in October alongside improved global manufacturing.

The Dow Jones industrial average .DJI was up 34.54 points, or 0.36 percent, at 9,747.27. The Standard & Poor's 500 Index .SPX added 4.59 points, or 0.44 percent, at 1,040.78. The Nasdaq Composite Index .IXIC fell 2.48 points, or 0.12 percent, at 2,042.63.
