Weekly stock screens

Market Radar

Separate stock screens from chart indicators and review market breadth, weekly breakouts, one-year winners, and market-cap concentration.

What the radar answers

An index can rise while stock participation stays weak.

Market Radar separates stock participation from ordinary indicator charts. The same rally deserves a different read when it is broad, when it is concentrated in a few mega caps, or when it is driven only by short-term turnover.
