Screening Small-Cap Chinese Stocks for Strength and Positive Earnings

Summary

This document outlines a Chinese equity screen that combines a price movement threshold, a market capitalization ceiling, positive net profit, and a candle pattern intended to identify the start of a strong advance. The formula and Python example implement the conditions using current and prior prices, market value, reported profit, and intraday high, low, and open prices. The article presents small capitalization as a potential source of growth and profitability as a basic quality filter.

The proposed screen is qualitative: it gives no backtest, performance statistics, or evidence that the selected candle conditions predict further gains. The author notes that relying on the “main rise” signal can overlook other factors, smaller stocks can be more volatile, and the simple rule may have gaps. Suggested refinements include adding valuation measures and considering industry strength. The threshold and data definitions may depend on the platform and market data conventions, so the examples alone do not establish that the screen is robust or suitable for live trading.

Key ideas

• The screen combines a price move above 1% with a market value no greater than 10 billion yuan and positive net profit.
• It uses the relationship among open, high, and low prices, plus a rising open, to represent a possible advance launch.
• The article identifies small-cap volatility as a key risk.
• It suggests adding valuation measures and assessing industry competitiveness.
• No backtest evidence is given for the screening rule.
