Screening Main Board Stocks by Range, Float Value, and Daily Gains

Summary

This document describes a daily screen for main board stocks whose intraday range exceeds 1%, circulating market capitalization exceeds 10 billion yuan, and price rises by more than 1% on the day. It combines a measure of trading activity, a company-size threshold, and a short-term price filter. The page also gives formula and Python examples for applying those conditions, including a random selection from the qualifying list.

The author cautions that the screen omits company fundamentals and longer-term price behavior. A one-day gain does not establish future upside, and technical criteria cannot predict longer-run performance. Suggested refinements include considering fundamentals and adapting the factors to market conditions. No backtest results or performance evidence are provided, so the criteria should be understood as a screening recipe rather than a demonstrated strategy.

Key ideas

• The screen requires an intraday price range greater than 1% and a daily gain greater than 1%.
• It excludes stocks whose circulating market value is at or below 10 billion yuan.
• The selection is limited to main board stocks.
• The document warns that one-day price action does not establish future performance.
• It proposes adding fundamental measures and adapting selection criteria to market conditions.
