correlation — how two names move together
Return correlation between two names
The return correlation of INTC and AAPL from ~2 years of real daily returns — how tightly the two move together. A low or negative correlation means they diversify each other; a high one means they rise and fall as one. Real-only; a name is 1.00 correlated with itself.

β of INTC on AAPL

Pearson correlation of daily log-returns over ~2 years (and a recent 63-day window — one short window, so expect it to move around the full-window figure). R² is the share of INTC's moves explained by AAPL; β on AAPL is how INTC has moved per 1 move in AAPL. Correlation runs from −1 to +1 — negative (green) means the two have moved opposite over this window, and correlations tend to rise toward 1 in a sell-off. Your decisions, your risk.
