Weekly Market Breadth Report — July 17, 2026
Corrected 18 August 2026. This post was produced by an earlier breadth/regime engine later found to contain calculation errors. In this post: advance/decline figures were computed from a contaminated series and have been recomputed from the corrected data; one regime-signal takeaway described an event the corrected data does not contain and has been removed; one regime-signal takeaway was reworded — the signal did fire, but its forward-return framing did not survive revalidation; forward-return claims that rested on a backtest of the same faulty series have been dropped; 2 charts plotted from the old engine have been removed; the 'what happened' scorecard on the previous week's takeaways has been dropped. Price data, signal counts, ETF tables and index moves are unaffected.
