Where each S&P 500 sector sits on the rotation map versus the market, computed live from Yahoo Finance (no key, nothing stored). The Relative Rotation Graph is how professional allocators visualise sector rotation: it plots each sector on two axes — relative strength (is it out- or under-performing the S&P 500) and relative momentum (is that relative strength improving or fading) — and the combination lands each sector in one of four quadrants that rotate clockwise over time: Leading (strong and getting stronger), Weakening (strong but losing steam), Lagging (weak and getting weaker) and Improving (weak but turning up). Money rotates Improving to Leading to Weakening to Lagging, so the quadrant tells you not just who is winning but who is next. This computes each of the eleven SPDR sectors' RS-Ratio and RS-Momentum against the S&P 500 and places it in its quadrant. The rrg endpoint returns the whole rotation map; the sector endpoint returns one sector's coordinates and quadrant; the sectors endpoint lists what is covered. The sector-rotation RRG / quadrant cut — distinct from the relative-strength ranking (a one-dimensional list), the sector price/performance feed and the correlation APIs. It shows the rotation, not just the ranking.

Which markets are beating the benchmark and which are lagging, ranked, computed live from Yahoo Finance (no key, nothing stored). Relative strength is the engine of rotation: money flows toward what is outperforming, and the leaders of one quarter often lead the next. For a cross-asset, cross-sector universe — the eleven S&P 500 sectors plus small caps, international and emerging equities, gold, oil, commodities, bonds and crypto — this measures each asset's return MINUS the S&P 500's over one, three and six months, blends them into a relative-strength score, and ranks the whole board into leaders and laggards. A positive score means the asset is beating the market; a negative one means it is lagging. The ranking endpoint returns that ranked board with the benchmark's own return and the standout leaders and laggards. The asset endpoint returns one market's relative strength across each window, its beta to the S&P 500 and whether its relative strength is improving or fading. The universe endpoint lists what is covered. The relative-strength / market-leadership rotation cut — distinct from the absolute-momentum, the sector-correlation and the altcoin-season APIs. It answers what is leading the market, measured against it.

Which corner of the commodity complex is leading and which is lagging, ranked by trailing momentum, computed live from Yahoo Finance futures (no key, nothing stored). A price tells you where a commodity is; momentum tells you where the money is flowing. This scores every major commodity — crude, Brent, natural gas, gasoline and heating oil in energy; gold, silver, copper, platinum and palladium in metals; corn, wheat and soybeans in grains; coffee, sugar, cocoa, cotton and orange juice in softs; live cattle and lean hogs in livestock — by its return over five horizons (1 week, 1 month, 3 months, 6 months and a ~1-year proxy), blends them into a single momentum score and ranks the whole complex into leaders and laggards. The screener endpoint returns that ranked table with a relative-strength rank and trend regime for each. The momentum endpoint drills into one commodity: its multi-horizon returns, where it sits versus its 50- and 200-day averages, and a trend label. The commodities endpoint lists what is covered. The cross-commodity momentum / relative-strength factor cut — distinct from the commodity-price feed (front-month prices), the commodity-spreads API (crack/crush/ratios) and the precious-metals spot API. It answers what is leading the complex, not what one thing costs.
