U.S. Stock Futures Up Slightly

NEW YORK (AP) — Wall Street appears headed for a subdued opening, as the absence of stimulus action by central banks in the U.S. and China dismays investors while the German economy shows signs of weakening.

Dow Jones industrial average futures are up 15 points to 13,171. Standard & Poor's 500 index futures are up 4 points to 1,413. Nasdaq futures are up 14 points to 2,789.

Investors are growing cautious about the prospect of more economic stimulus from central banks in China and the U.S. The London stock market is closed for a bank holiday, keeping trading in check.

A big event that could move the market lies ahead — U.S. Federal Reserve Chairman Ben Bernanke's speech in Wyoming later this week.
