I use both the $NYSI and $NASI to help determine intermediate directional turns. They have both reached extreme overbought status. That said the strength there is very good in pointing out that after this selling runs its course we are quite likely to see a significant bull run.
The $NYSI should go negative after this evening's numbers are factored in. The chart actually is closer to approximating the ascent after the March 2003 bottom than the retest that preceded it but I just can't believe we won't get some additional selling that will bring the market breadth indicators like BPNDX back into more traditional buy ranges nearing a reading of only 30 buy signals.
