The index soars, but the troops don't follow

by Sentimentrader
2026-04-28
A breadth divergence study shows the S&P 500 stretched over 6% above its 200-day moving average while fewer than 60% of SPY components hold above theirs — a rare signal refined by a 126-day cooling-off filter. After prior filtered triggers, the index rose 100% of the time over the next six months.

Key points:

  • The S&P 500 sits nearly 7% above its 200-day average, yet less than 60% of SPY components trade above their own 200-day line
  • This divergence has triggered only 20 times since 1998 - adding a 126-day cooldown reduces it to 9 independent signals
  • The Fear & Greed Index just completed a full round trip from below 10 to above 80, a cycle that has happened 25 times in the index's history
  • Short-term returns after the F&G cycle favor caution, but longer windows show the index was higher 78% of the time a year later

Price leads, breadth lags

The S&P 500 closed at 7,173 on April 27, stretching more than 6% above its 200-day moving average. By itself, that's not unusual during a bull run - indices are supposed to lead their components. 

But underneath the surface, participation has thinned. Fewer than 60% of SPY constituents hold above their own 200-day averages. The index is running ahead of its own internals.

When the S&P trades this far above its trend while breadth trails, it has triggered a signal only 20 times since 1998. The cluster is telling - 1998 and 1999 account for nine of those, and five fired during the post-C

Users should conduct their own due diligence and consider their individual circumstances before making any financial decisions. Past performance is not necessarily indicative of future results.

Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
