Returns — daily closes over the lookback window, aligned on the trading days every ticker shares, converted to simple daily returns close_t / close_(t-1) − 1.
Correlation — Pearson's r on each pair's aligned return series: cov(a,b) / (σa × σb), from −1 (perfect hedge) to +1 (same trade).
Reading it — above ~0.8: the pair is one bet wearing two tickers. 0.3–0.8: related but distinct. Below ~0.3: genuine diversification. Negative: a natural hedge — rare among equities, more common across asset classes.
Caveats — correlations are regime-dependent and tend to spike toward 1 in crashes exactly when you need them low; a 1-year window smooths over that. Pearson also only captures linear co-movement.
