S&P 500 Holds Near Highs as T2108 Slides to 23.9, Breadth Divergence Widens

Andrew@CANSLIM RESEARCH's avatarAndrew@CANSLIM RESEARCH

The S&P 500 sits at 7,650.50, down just 0.8% from its 7,711.23 close on 2026-08-28, yet the percentage of stocks above their 40-day moving average has collapsed from 41.9 to 23.9 over the same 21-session window. The index has barely budged while the underlying participation has thinned dramatically.

The Story So Far

The shift began on 2026-08-28, when the 5-day ratio first fell below 1.0 and T2108 first dropped below 50, signaling that sellers had taken control. T2108 then broke below 40 on 2026-08-31 and continued to deteriorate, touching 23.9 by 2026-09-18. The S&P 500 briefly rallied to 7,747.71 on 2026-09-03, but breadth never confirmed that strength, and the index has since drifted back toward 7,650.50.

Reading Today’s Signals

Today’s 4% movers show 253 up versus 235 down, with a 5-day ratio of 0.97 and a 10-day ratio of 0.85, indicating that selling pressure remains slightly ahead of buying interest. T2108 at 23.9 is below the 30 threshold, a washed-out reading that historically has preceded at least short-term bounces. 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 closed at 6,575.32; no other historical match was found in the loaded data.

Divergence Check

The index and breadth are diverging: the S&P 500 is down only 0.8% over the window while T2108 has fallen 18.0 points, or 43.0%. This implies that the index’s resilience is masking broad-based weakness beneath the surface.

Desk Verdict

Red. The verdict is Red because the 5-day ratio of 0.97 sits in the neutral 0.5-1.5 band, T2108 at 23.9 is below 30 and thus washed out, and quarterly breadth is roughly balanced at 1040 stocks up 25%+ versus 1262 down 25%+. These factors collectively point to a market that is internally weak despite the index’s modest decline.
