NEW YORK, March 26 (Reuters) - U.S. stocks fell for a fourth straight session on Thursday but indexes ended well off session lows with support from economic data and earnings, including Accenture's.
Semiconductor stocks were again under pressure, this time after SanDisk cut its revenue outlook. Its shares tumbled 18.4 percent to $66.20 and an index of chipmaker shares fell 1.4 percent. The index fell as much as 3.5 percent earlier.
