S&P 500 Gains 1.0% While T2108 Falls to 22.8, Marking a Divergence Between Index and Breadth

Andrew@CANSLIM RESEARCH's avatarAndrew@CANSLIM RESEARCH

The S&P 500 has climbed 1.0% over the past 21 sessions, yet the percentage of stocks above their 40-day moving average has dropped sharply. That gap between index performance and underlying participation defines the current market.

The Story So Far

The picture began changing on 2026-08-31, when T2108 first fell below both 50 and 40, and the 5-day ratio slipped below 1.0 on 2026-09-01 as sellers took control. T2108 deteriorated from 39.2 on 08/31 to 22.8 by 09/21, with the S&P 500 touching 7,551.81 on 09/16 before rallying to 7,765.10. The most recent session saw 144 stocks up 4% or more against 78 down, but the 10-day ratio of 0.84 remains below 1.0.

Reading Today’s Signals

Today’s 4% movers at 144 up versus 78 down, a 5-day ratio of 1.12, and T2108 at 22.8 indicate that short-term trading has turned neutral while the broader participation measure is washed out. The most recent earlier session with a comparable T2108 in the loaded data was 2026-04-01, when T2108 stood at 25.2 and the S&P 500 was at 6,575.32. No other historical comparison was found in the loaded data.

Divergence Check

The index and breadth are diverging: the S&P 500 is up 1.0% over the window while T2108 has fallen 16.4 points. That implies the rally is being carried by a narrowing group of stocks rather than broad participation.

Desk Verdict

Red. The verdict is Red because the 5-day ratio of 1.12 sits in the neutral 0.5-1.5 band, T2108 at 22.8 is below 30 and washed out, and quarterly breadth is roughly balanced at 1066 stocks up 25% or more versus 1190 down 25% or more.
