S&P 500 Constituents API

salutare 3,458 Abbonati

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.

Sektor-Rotations-RRG (Relative Rotation Graph) API — oanor API marketplace

Sektor-Rotations-RRG (Relative Rotation Graph) API

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.

 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.

 Stock Sector Correlation Matrix API — oanor API marketplace

Stock Sector Correlation Matrix API

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.

 Stock Index Seasonality API — oanor API marketplace

Stock Index Seasonality API

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.
