Stocks futures edged down on Wednesday, pointing to a slightly weaker start for Wall Street, with some caution persisting ahead of a private sector jobs report.

Futures for the Dow Jones, the S&P 500 and the Nasdaq were all down 0.1 percent.

The ADP report, due at 1215 GMT (8:15 a.m. ET), is expected to show the private sector created 40,000 jobs in March as the world's largest economy emerges from recession.

The report will be keenly eyed as it comes ahead of the crucial non-farm payrolls figures, which are due on Friday when U.S. markets are closed.

Other economic data likely to garner interest include March's New York ISM survey, Chicago PMI, February factory orders and the revised February durable goods orders.

Among companies reporting results on Wednesday include Mosaic which releases third-quarter earnings. Analysts expect the firm to post $0.62 earnings per share compared to $0.13 a year ago.

Other companies to report include Micron Technology, Acuity Brands, A.Schulman, Research in Motion and Rite Aid
