Crypto and stock correlation matrix

• 0.6 and above
• 0.3 to 0.6
• −0.3 to 0.3
• −0.6 to −0.3
• −0.6 and below

• One number per pair

  Each cell is the correlation coefficient r of two markets' daily returns. The diagonal is always +1: a market compared with itself.

• Returns, not prices

  Two prices that both trend up look related on a chart even when their daily moves are not. The matrix compares the day-to-day changes, which is what a hedge or a second position actually faces.

• Windows disagree on purpose

  30 days shows the current regime, 90 days the background. When the two differ a lot, the relationship is unstable, and a pair that looked like a hedge last month may not be one now.

• Correlation is not a forecast

  A high r says two markets moved together in the window. It says nothing about direction, and it can break exactly on the days that matter.

Daily candles come from the public BRVX chart feed (v1.rates.getChart, 1d, mid price) for each market's SYMBOL/USDT pair. We take close-to-close returns on the UTC calendar, drop today's unfinished candle, keep only days every market has, and compute Pearson r for each pair over the last 30 and 90 of those days. Stock, index, commodity and EUR prices on BRVX are a synthetic feed that keeps moving at night, at weekends and on US holidays, so weekend days are included for every market. Results will differ from studies that use exchange closing prices and trading days only.
