Ranking Mainboard Stocks by Heat Within Turnover and Float-Value Bands

Summary

The document describes a Chinese-market stock selection screen for mainboard shares. It first filters for a turnover rate between 3% and 12% and a circulating market value between 5 billion and 10 billion yuan, then ranks qualifying stocks by a heat or popularity measure, highest first. It provides a formula-style expression and a Python example that implement these criteria.

The rationale is to focus on actively traded, medium-sized companies attracting market attention. The document warns that popularity can become excessive and that selecting by market interest alone neglects company fundamentals, potentially exposing investors to losses if a favored stock reverses. It gives no historical results, definition of the heat metric, rebalancing schedule, or evidence that the screen improves returns. It suggests adding fundamental factors and diversifying as possible safeguards.

Key ideas

• The screen limits candidates to mainboard stocks in stated turnover and circulating-value bands.
• Qualifying stocks are ranked from highest to lowest by a heat or popularity measure.
• The example code applies the filters and returns stocks in that ranking order.
• Popularity-based ranking may overlook fundamentals and expose the portfolio to crowded or overheated names.
• The document provides no backtest or precise definition of its heat measure.
