Sectors tell you whether the market is playing offense or defense. Hunt for names one level down — in industries and themes — and check the leaders inside each sector.
Composite relative strength (RS) blends each GICS sector's excess return vs the S&P 500 across four lookback windows — 3, 6, 9, and 12 months — using recency weights of 0.4, 0.2, 0.2, and 0.2. The blend becomes a rank from 1 (strongest) to 11. TickerStance recomputes every rank nightly after the US close and reports conditions; it does not recommend positions.
Δ21 is the change in a sector's composite RS rank over the trailing 21 trading days — roughly one month. Positive means the sector climbed in rank; negative means it slipped. A sector moving from rank 8 to rank 3 over 21 days tells a different story than one that has sat at rank 3 for months.
Cross-horizon divergence breaks each sector's RS rank out by individual window — 3, 6, 9, and 12 months — instead of the blended composite. A sector ranked 1 on the composite but 9 on the 3-month window has short-term weakness under a strong long-term trend; the reverse is a fresh breakout from a weak base. Divergence between short and long windows often precedes composite rank changes.
Each sector ETF's excess return vs SPY is measured over 3-, 6-, 9-, and 12-month windows from daily price history, then blended with IBD-style recency weights (0.4/0.2/0.2/0.2) into a composite rank. Leader counts cross-reference the daily stock RS leaderboard against each sector's GICS membership. The same calculation runs every trading day; the methodology is fixed.
Composite RS uses IBD-style multi-horizon weights (3m / 6m / 9m / 12m at 0.4 / 0.2 / 0.2 / 0.2, recency-weighted). Per-horizon RS is each sector ETF's excess return vs SPY over that lookback, from daily price history. Leader counts cross-reference the daily stock RS leaderboard with each sector's GICS membership. Ranks are recomputed every trading day. Read how to read sector rotation, or hunt one level down on industries and leaders.
