Relative strength versus SPY, by horizon

Relative strength is the name's price return minus SPY's over 1, 3, 6 and 12 months, computed from daily closes (price return; dividends excluded) — a return difference in percentage points, positive when it outperforms the market and negative when it lags. A recency-weighted blend produces the leadership classification; the short-versus-long comparison indicates whether that leadership is accelerating.
