Doesn't this need to be graphed along with the overall PC ratio. Seems like the article suggested that there was an inverse relationship between the pure QQQ PCR and the standard PCR -- each an indicator of the same thing but at inverse individual magnitudes. Even if that relationship has not held true for the last month or so, during what apears to be an irrational rally, it seems that any analysis of the issue has to include both QQQ PCR and overall PCR.

Then again, this may just prove that no "system" is always right.
