STAN CHOE AP Business Writer Wall Street is falling in another erratic day of trading Wednesday, weighed down by worries about a slow recovery for the economy. The market has been wavering the last couple weeks after coming off its best month in a generation, as optimism about reopening the economy collides with worries about the dangers of lifting restrictions too soon. The S&P 500 was down 2.3%, as of 12:18 p.m. Eastern time, with the sharpest losses coming for stocks that most need a healthy economy for their profits to grow. Trading was volatile, and the index went from an early loss of 1.1% to a gain of 0.1% and back to more losses, all in the span of 90 minutes. The Dow Jones Industrial Average was down 576 points, or 2.4%, at 23,188, and the Nasdaq composite was down 2.6%.
