We wrote in the latest Green Book that a breadth indicator that should be more well-known than it is—the High/Low Logic Index (or HLLI)—had moved to “maximum negative” right at the cycle high in the NASDAQ Composite on November 19th. Specifically, the 10-week moving average of this indicator showed a perilous internal condition in which too many NASDAQ stocks were reaching 52-week New Highs and New Lows simultaneously. That’s the very definition of a “fractured” market, and has preceded some important NASDAQ declines. There have also been a couple of premature warnings, as in the summers of 1996 and 2019.
