Screening Main-Board Stocks by Turnover, Float Value, and Prior Limit-Ups

Summary

This document describes a main-board stock screen requiring turnover between 3% and 12%, circulating market value between 5 billion and 10 billion, and no limit-up on the previous day. It includes formula and Python examples intended to filter stocks using these conditions, though it provides no measured returns or backtest results.

The accompanying discussion says the screen focuses on liquidity, market capitalization, and a recent price event. It cautions that the criteria rely heavily on historical data and omit company fundamentals, sector conditions, and other market influences. Suggested refinements include adding technical indicators, grouping stocks by capitalization or industry trends, and combining technical and fundamental measures. The code examples should be checked against the stated rules before use, since the post does not demonstrate that they implement the conditions correctly.

Key ideas

• The screen combines turnover, circulating market value, and the absence of a prior-day limit-up.
• It is restricted to main-board stocks.
• No backtest or performance evidence is included.
• The post warns that the criteria rely on limited historical and market data.
• Technical, industry, and fundamental factors are suggested as possible additions.
