Wo jeder S&P-500-Sektor auf der Rotationskarte im Vergleich zum Markt steht, live berechnet aus Yahoo Finance (kein Key, nichts gespeichert). Der Relative Rotation Graph ist, wie professionelle Allokatoren die Sektorrotation visualisieren: Er zeichnet jeden Sektor auf zwei Achsen — relative Stärke (über- oder untertrifft er den S&P 500) und relatives Momentum (verbessert oder verschlechtert sich diese relative Stärke) — und die Kombination platziert jeden Sektor in einem von vier Quadranten, die sich im Uhrzeigersinn drehen: Leading (stark und stärker werdend), Weakening (stark, aber nachlassend), Lagging (schwach und schwächer werdend) und Improving (schwach, aber sich verbessernd). Geld rotiert von Improving zu Leading zu Weakening zu Lagging, sodass der Quadrant nicht nur sagt, wer gewinnt, sondern wer als Nächstes dran ist. Dies berechnet für jeden der elf SPDR-Sektoren das RS-Ratio und RS-Momentum gegenüber dem S&P 500 und platziert ihn in seinem Quadranten. Der rrg-Endpunkt gibt die gesamte Rotationskarte zurück; der sector-Endpunkt gibt die Koordinaten und den Quadranten eines Sektors zurück; der sectors-Endpunkt listet auf, was abgedeckt ist. Die Sektor-Rotations-RRG / Quadranten-Aufteilung — unterschieden vom Relative-Stärke-Ranking (einer eindimensionalen Liste), dem Sektor-Preis/Performance-Feed und den Korrelations-APIs. Sie zeigt die Rotation, nicht nur das 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.

How the eleven S&P 500 sectors move together, computed live from Yahoo Finance via the SPDR sector ETFs (no key, nothing stored). Sector correlation is the heart of equity diversification and rotation: defensives (utilities, staples, health care) and cyclicals (tech, discretionary, financials, energy) cluster differently, and when correlations rise the whole market is moving as one (risk-on/risk-off), while a spread of correlations means stock-picking and rotation are rewarded. The matrix endpoint returns the full pairwise return-correlation matrix across all eleven sectors with the most- and least-correlated sector pairs. The sector endpoint returns one sector's correlation to every other, ranked, plus its beta to the S&P 500 (how much it amplifies the market). The sectors endpoint lists what is covered. The equity sector correlation / rotation cut — distinct from the cross-asset correlation matrix (asset classes, not sectors), the crypto and currency correlation APIs (other markets) and the sector price/performance feed. It answers which sectors are the same bet and which diversify, within the stock market.

Die Kalendermuster, um die sich Aktienhändler positionieren – „Sell in May“, die Santa-Claus-Rallye, der September-Einbruch – live berechnet aus ~10 Jahren Yahoo Finance-Monatsdaten der wichtigsten Aktienindizes weltweit (kein API-Key, nichts gespeichert). Aktien haben gut dokumentierte saisonale Tendenzen, und dies misst sie direkt: Für jeden Index werden zehn Jahre monatlicher Renditen genommen, nach Kalendermonaten gruppiert und die durchschnittliche Rendite in jedem der zwölf Monate, der Anteil der Jahre, in denen dieser Monat positiv war (die Gewinnrate), sowie die historisch stärksten und schwächsten Monate zurückgegeben. Der Saisonalitäts-Endpunkt gibt das vollständige 12-Monats-Saisonalitätsprofil eines Index plus die historische Tendenz des aktuellen Monats zurück. Der Monats-Endpunkt dreht es um: Für einen Kalendermonat wird jeder Index nach seiner historischen Durchschnittsrendite eingestuft, sodass Sie sehen können, welche Märkte gerade saisonal stark oder schwach sind. Der Indizes-Endpunkt listet auf, was abgedeckt wird, vom S&P 500, Nasdaq, Dow und Russell bis zum DAX, FTSE, CAC, Euro Stoxx, Nikkei und Hang Seng. Der Aktienindex-Saisonalitäts-/Kalendermuster-Schnitt – abgegrenzt von den FX-, Rohstoff- und Krypto-Saisonalitäts-APIs, dem Indexpreis-Feed und den Bestandteils-APIs.

How broad the US stock market's move really is under the surface, computed live from Yahoo Finance across a large-cap universe (no key, nothing stored). The S&P 500 can be dragged up by a handful of megacaps while most stocks fall; breadth tells you how many stocks are actually participating. The breadth endpoint scans a ~50-name large-cap universe spanning every sector and returns the share trading above their 20-, 50- and 200-day moving averages (the classic participation gauges), the advancers versus decliners on the day, the advance/decline ratio, the average and median daily change and a regime label (broad strength, mixed or broad weakness). The components endpoint returns the per-stock table behind it — each name's price, daily change and whether it is above each moving average — so you can see exactly which stocks are carrying or dragging the market. The constituents endpoint lists the universe. The equity market-internals / breadth cut — distinct from the crypto-breadth API (which scans coins), the single-quote, index-constituent and movers APIs. It answers whether a rally is broad or narrow, not how one stock is doing.

Live financial futures as an API — front-month prices for the major US index and Treasury futures, served from Yahoo Finance. For any contract it returns the current price, the previous close, the absolute and percentage change on the day, the day's high and low, the 52-week high and low, the contract month and the currency. Index futures (E-mini S&P 500, Nasdaq-100, Dow, Russell 2000) trade nearly around the clock and are the market's go-to read on where the open is heading; Treasury futures (2-, 5-, 10- and 30-year notes and bonds) track interest-rate expectations. Look a contract up by name or ticker alias, pull a category board (index or rates) ranked by the day's move, or get the whole board in one call. The futures-quote layer for trading, pre-market and dashboard apps. Live, no key, no cache. Distinct from spot index APIs and from the physical-commodity futures API — this is financial (index and rate) futures.

Live world stock-index levels as an API — the current level of the major stock-market indices, served from Yahoo Finance. For any index it returns the current level, the previous close, the absolute and percentage change on the day, the day's high and low, and the 52-week high and low, in the index's own currency. Look an index up by name or ticker alias (S&P 500, Nasdaq, Dow, FTSE 100, DAX, CAC 40, Euro Stoxx 50, Nikkei 225, Hang Seng, Sensex, ASX 200 and more), pull a regional board ranked by the day's move (US, Europe, Asia, Americas), or get the headline world board in a single call. The live index-quote layer for trading, markets and dashboard apps. Distinct from S&P 500 and Nasdaq constituent-directory APIs — this returns the live index level, not the member list.

The current members of the S&P 500 stock index as an API — the reference a stock screener, portfolio tool or research dashboard needs. For each of the ~500 constituents: its ticker symbol, the company name, its GICS sector and sub-industry, the headquarters location, the date it was added to the index, its SEC Central Index Key (CIK, ready for EDGAR look-ups) and the year it was founded. Look a constituent up by symbol or name, list every company in a GICS sector, search across symbols, names, sub-industries and headquarters, or list the whole index with a per-sector breakdown. This is the index-membership and sector-classification reference — not live prices (finance-api), SEC filings (edgar-api) or the global legal-entity register (companies-api). Served from memory — always fast.
