Weekly Market Breadth Report — May 29, 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 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.

Key Takeaways
- 🟡 S&P 500: Rallied +1.4% to 7,580, but breadth is not fully confirming. Price is moving up while internals remain mixed.
- 🟢 MSCI World (ACWI): Gained +1.6%, tracking US markets. The rally is global.
- 🟡 Breadth: Momentum is weak (2/6) while trend is in the mid-range (2/6). Short-term selling pressure within a mixed structural backdrop. Momentum just weakened — a fresh deterioration in short-term indicators.
- 🔴 Breadth — 52-Week High/Low: At an extreme reading (z=-1.8). Uncommon weakness — could mark a washout or further downside.
- 🟡 ASX 200: McClellan Oscillator crossed above zero — breadth momentum shifted from negative to positive. Descriptive context only; zero-crosses showed no forward edge in our backtest.
