How this works (click to show / hide)
- Breadth = the % of a sector's stocks trading above their 20-, 50- and 200-day average price (short, medium, long trend). Every stock counts equally.
- Trend breadth = the simple average of those three percentages. Now / 5D / 1M / 3M ago are its levels today and 5, 21 and 63 trading days earlier; ▲/▼ shows whether it is now higher or lower.
- S&P 500 row & history chart: the pinned top row pools all ~500 stocks together (it is not an average of the 11 sectors). The history chart shows its trend breadth (black) with %>20DMA (orange), %>50DMA (green) and %>200DMA (red) over ~12 months; above 50% (green zone) means most stocks are in an uptrend. "Sector participation" counts how many sectors are Improving / Deteriorating and how many have trend breadth above 50%.
- Level: Strong ≥ 60%, Neutral 40–60%, Weak < 40%.
- Direction (from the changes): Improving = up 10+ pts over 1M and not down over 5D. Deteriorating = down 10+ over 1M and not up over 5D. Reversing Up = down 10+ over 1M but up 10+ over 5D. Reversing Down = up 10+ over 1M but down 10+ over 5D. Otherwise Stable.
- Highs − lows (H-L) = % of stocks at a 20-day (or 52-week) closing high minus % at a low. Positive means more new highs than lows.
- Score (0–100) = 50% trend breadth + 25% highs−lows + 25% relative-strength momentum rank vs the other sectors. "Wk Δ" is the change vs 5 days ago.
- Rotation chart: each sector's ETF strength vs SPY (x: above/below 100 = outperforming/underperforming its recent average) against how fast that is changing (y). Quadrants: Leading (strong & rising), Weakening (strong but fading), Lagging (weak & falling), Improving (weak but rising). Tails show weekly points over the last month (t-20, -15, -10, -5, today); the arrow marks today.
- Industry flags: a sub-industry with at least 4 stocks is flagged when its %>50DMA differs from its sector's by more than 25 points – an early sign of what is driving (or lagging) the sector.
- Data: daily closes from Yahoo Finance; the day's bar is used only after the close. Not investment advice.
