This ratio measures the dominance of the largest stocks in the market relative to the broader group.

A rising ratio suggests that market performance is being driven primarily by a few heavyweight names, while the rest of the market lags behind — often signaling narrow leadership and increased fragility beneath the surface.

In contrast, a falling ratio implies broad participation, where smaller and mid-sized names are catching up, indicating a healthier and more sustainable rally.

The ratio can be used to track internal market strength, detect early signs of exhaustion in top-heavy rallies, or confirm turning points in investor sentiment.
