From the desk of Willie Delwiche.
The late-July breadth thrust provides a breadth thrust regime that lasts for a year (or more if we get additional breadth thrusts between now and mid-2023). In such an environment, near-term oversold conditions tend not to persist and, in fact, reverse quite quickly. One way of measuring this is to look at the percentage of world markets trading above their 50-day average. Anything above 70% is pretty good participation, whether we are in a bullish breadth thrust regime or not. Below 40% is a different story. Without a breadth thrust as support, the S&P 500 struggles to make headway when the percentage of world markets above their 50-day average collapses. But within breadth thrust regimes, it signals an oversold condition that leads to strength.
The percentage of world markets above their 50-day average was at 90% in mid-August and is now down to just 25%. The recent breadth thrust suggests that rather than a red light arguing for caution, the signal now is a greenlight encouraging exposure.
