What this measures
Risk-on co-movement
When Bitcoin rises and falls alongside the S&P 500 (positive correlation), it is trading as a risk-on asset — moving with broad equity-market sentiment rather than on crypto-specific catalysts.
Decoupling
When correlation is near zero or negative, Bitcoin is trading on its own flows — halving cycles, on-chain activity, crypto-native leverage — largely independent of the stock market.
Data source
S&P 500 uses the index’s continuous daily-close history via stooq.com, a free public feed with no API key. Bitcoin uses Binance BTCUSDT daily closes. Because equities only trade on weekdays, this tracker aligns to shared calendar dates rather than reporting a 7-day BTC series.
