The S&P 500 has slipped 2.3% over the past 21 sessions to 7,551.81, yet the more telling move lies beneath the surface: T2108 has collapsed from 45.2 to 24.5 over the same window. The index is down modestly; the average stock is down considerably more.
The Story So Far
The picture began changing on 2026-08-27, when T2108 first fell below 50, and deteriorated further on 2026-08-28 as the 5-day ratio dropped below 1.0 for the first time, signalling that sellers had taken control. T2108 then broke below 40 on 2026-08-31 and has ground steadily lower since, touching 24.5 by 2026-09-16 and holding there through 2026-09-17. The 5-day ratio has oscillated below 1.0 for most of the window, though today’s reading of 1.01 reflects a session in which 4% movers skewed heavily to the upside, 374 versus 85.
Reading Today’s Signals
Today’s 4-count of 374 up versus 85 down is a sharp one-day reversal from the selling pressure that has dominated since late August, but the 5-day ratio of 1.01 sits in the neutral 0.5–1.5 band, and the 10-day ratio of 0.90 remains below parity. T2108 at 24.5 is below 30, a level conventionally described as washed out; the most recent earlier session with a comparable reading in the loaded data was 2026-04-02, when T2108 stood at 27.5 and the S&P 500 was at 6,582.69. No exact historical match was found in the loaded data.
Divergence Check
The index and breadth are diverging: the S&P 500’s 2.3% decline over the window is modest, while T2108’s 20.7-point drop is severe. This implies that weakness is broad-based rather than concentrated in a few large-cap names, and that the index’s resilience may be masking deeper damage beneath the surface.

Desk Verdict
Red. The verdict is Red because the 5-day ratio of 1.01 sits in the neutral 0.5–1.5 band, T2108 at 24.5 is below 30 and therefore washed out, and quarterly breadth is roughly balanced at 1071 stocks up 25%+ versus 1242 down 25%+. No single metric is extreme enough to force a more decisive signal, but the combination of a washed-out T2108 and a diverging index leaves little room for complacency.
