NEW YORK ( TheStreet) -- U.S. stock futures were signaling Wall Street would open higher on Wednesday ahead of a rates announcement from the Federal Reserve. European shares were rising while Asian stocks finished Wednesday's trading session with losses as manufacturing in China slowed. Japan's Nikkei 225 average closed down 0.6% at 8,641.85. The economic calendar in the U.S. Wednesday includes the Federal Open Market Committee rate decision at 2:15 p.m. EDT; Automatic Data Processing's employment change report for July at 8:15 a.m.; the Institute for Supply Management's manufacturing index for July at 10 a.m; and construction spending for June at 10 a.m. U.S. stocks on Tuesday fell for a second consecutive session with traders showing some nervousness as the Fed began its two-day policy meeting. The Fed will issue its decision on interest rates Wednesday afternoon. More quantitative easing from the central bank would be a surprise but a change in the Fed's pledge to keep rates at historic lows for longer than currently telegraphed is viewed as likely.
