StockScore

Score the business. Read the market.

StockScore does both. A 100-point score for quality, value and moat — and a score-free read on the sentiment, IPOs and events around it. Search any company or ETF; every card is live data.

The product

One score, fully shown

A score you can't inspect is just an opinion with a number on it. Every StockScore shows its working: the figures behind each pillar, and how complete the underlying data is.

Signals & events

Context, deliberately score-free

Not everything deserves a number. Three surfaces carry the context around the score — where the crowd leans, how a deal is pricing, what is actually known. No 0–100, no gauge; direction lives on its own blue↔violet axis that never touches the score's palette.

Sentiment Radar
Seven signals across options, expectations and prediction markets — a direction and a confidence, never a number. The same verdict rides beside each holding in your watchlist.

IPO Radar
A deal, before there's a quarter to score: range moves, S-1 structure facts from EDGAR, and the lifecycle to listing.

Event Brief
A hand-curated, fully sourced read on a marquee event — bull and bear laid out for you to weigh.

Under the hood

One request flow, four destinations

A Next.js client talks to FastAPI through a proxy that owns timeouts and strips auth. FastAPI dispatches by route: one path scores, three add score-free context. The same two-tier cache and bounded AI layer serve every route.

Data comes from many sources — yfinance primary, Alpha Vantage and Finnhub as fallbacks, justETF for funds, Polymarket and EDGAR for the surfaces — resolved to one record and cached in two layers: a hot in-process cache over Cloud SQL Postgres as the 90-day source of truth. Everything fails open.
