The Nasdaq Composite just ticked below 1939.20 to a new low for the nearly two-month downtrend. There's a potential bottom at 1932.26. And the index may be spared a heavy selloff if it finds a bottom at 1929.62, or at 1902.74. But a move below 1902.74 would break the uptrend since October 2002 and set the Nasdaq up for an extended downtrend, towards 1859.13, perhaps to the upper 1700.00 handle.(Dow Jones)
