NEW YORK (MarketWatch) -- The U.S. dollar declined versus major counterparts Wednesday after ADP Employment Services said private companies cut 473,000 jobs in June. The dollar index (DXY 80.01, -0.12, -0.15%) , a measure of the greenback against a trade-weighted basket of currencies, traded at 79.905, down from 80.179 in North American trading late Monday. Economists surveyed by MarketWatch expected a decline of 498,000 jobs. Still to come, a report on manufacturing is expected to show improvement in that sector's outlook.
