Sector Rotation RRG (Relative Rotation Graph) API

healthy 3,650 Subscribers

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.

Stock Sectors API — oanor API marketplace

Stock Sectors API

Live S&P 500 sector performance as an API — the sector-rotation picture traders watch, served from Yahoo Finance via the eleven SPDR sector ETFs. It returns each of the eleven GICS sectors — Technology, Financials, Energy, Health Care, Consumer Discretionary, Consumer Staples, Industrials, Materials, Utilities, Real Estate and Communication Services — with its tracking ETF's price, the day's change, the day's high and low, and the 52-week high and low. Pull the whole board ranked by the day's move, with the leading and lagging sectors called out, or look one sector up by name or ETF ticker. The sector-rotation and market-breadth layer for trading, macro-research and dashboard apps. Live, no key, no cache. Distinct from index-level, single-stock and cross-asset-ratio APIs — this is the equity-sector performance breakdown.

 Relative Strength vs S&P 500 API — oanor API marketplace

Relative Strength vs S&P 500 API

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.

 Commodities Momentum & Relative-Strength API — oanor API marketplace

Commodities Momentum & Relative-Strength API

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.

 Variance Ratio Test API — oanor API marketplace

Variance Ratio Test API

A formal statistical test of whether a market follows a random walk, or whether its returns carry tradeable momentum or mean-reversion that is real rather than noise — the Lo-MacKinlay variance ratio test, computed live from Yahoo Finance daily closes, no key, nothing stored. Most persistence tools give you a single descriptive number; this gives you a hypothesis test with a verdict. The variance ratio compares the variance of multi-day returns to the variance of one-day returns scaled up: under a true random walk the ratio is 1 at every horizon. A ratio above 1 means returns positively autocorrelate (trends persist — momentum); below 1 means they reverse (mean-reversion). Crucially it attaches a heteroskedasticity-robust z-statistic and a p-value at each horizon, so you know whether the deviation from a random walk is statistically significant or just sampling noise — the thing a point estimate cannot tell you. The asset endpoint runs the test at horizons of 2, 4, 8 and 16 days and returns each ratio, z-statistic, p-value and a reject/fail-to-reject verdict, plus an overall read. The screener endpoint ranks the cross-asset universe by their 2-day variance ratio, separating the statistically momentum-like markets from the mean-reverting ones. This is the random-walk hypothesis-test cut — distinct from the Hurst-exponent regime API (a point estimate with no significance), the momentum and the price APIs. It is the test, with the p-value attached.
