How To Read It
- A rising Mag 7 line means the biggest growth leaders are still dominating the tape.
- If the ex-Mag7 side starts leading, it usually signals healthier breadth and broader risk appetite.
- The biggest shifts matter when they persist across 1M, 3M, and 1Y views rather than one sharp week.
