The U.S. dollar lost ground on Thursday, the last trading day of the week for many markets ahead of Easter, after disappointing economic data on Wednesday raised doubts over the growth outlook ahead of key jobs data due Friday. Thursday’s pullback in the U.S. dollar index (.DXY), which is still up some 8 percent year-to-date, gave a boost to emerging-market stocks (.MSCIEF) — trading at a one-month high — as main emerging currencies strengthened against the dollar.
