How To Read It
- Watch which sectors stay near the top for more than a few sessions; persistent leadership usually matters more than brief spikes.
- Use the 30-day board for fast rotation and the 90-day board for the more durable trend.
- When leadership flips abruptly, the market is usually repricing growth, defensiveness, or rate sensitivity.
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.
