How the score works

——

The scanner aligns daily close-to-close returns to Nasdaq trading dates. Its 30-day score combines 75% positive Pearson-correlation strength with 25% direction agreement above a 50% baseline; a high reading describes recent coupling, not the next move.

Data & interpretation

Nasdaq Composite daily closes are retrieved from FRED, sourced from Nasdaq. BTC spot closes use Binance public market data with Coinbase as a fallback. Only derived statistics are displayed here.

Important: correlation is not causation. Macro events, liquidity, earnings and crypto-specific news can break the relationship quickly.
