In an earlier post, i discussed the Nasdaq-Nyse ratio and some rather dire market implications looking out 15 to 30 trading days. This post is a follow-up, but with a view of the weekly data.

On 7/2 The Nasdaq-Nyse volume ratio registered it's second consecutive reading above 1.75 on a weekly basis. We have seen this occur only 10 previous times, with the majority leading to lower closes 2 to 5 weeks later. The table below shows the performance of the S&P500 after such occurrences. What is also interesting to note is the bulk of the prior occurrences were during the tech speculative bubble.
