How To Read It
- This board shows how far each sector still sits below its own prior peak.
- Shallow drawdowns that recover quickly usually confirm strong leadership; deep drawdowns signal unfinished damage.
- It is especially useful when the main index looks fine but several sectors are still far from healed.
Breadth and sector charts tell you the weather. They just can't tell you which stock to hold for the next 10 days - that's the whole job of the Dig for Stocks algorithm.
