Nasdaq A/D is worse than 2 to 1 negative, the Up/Down volume is also poor, at 7
to 1.5. Not quite a 10 to 1 down day, but pretty ugly.
NYSE is marginally better: A/D is 5 to 3 to the downside, while up/down
volume is just over 2/1 negative.
Nasdaq appears to have broken its uptrend, while the SPX and Dow have not.
