On Wall Street, investors are bracing for a week that feels bigger than a normal turn of the calendar. Yet they remain optimistic: U.S. stocks look set to open a bit higher after the recent selloff. Oil is pushing up again, energy shares are catching a lift, aluminum producers are surging and fertilizer names are getting attention too. The second quarter starts on Wednesday: Jerome Powell is due to speak and so is John Williams. Fresh labor-market numbers are coming, capped by Friday's jobs report. Then Wall Street closes for Good Friday, which means traders have only a short window to process a week's worth of stress before the lights go out.
