A Chinese Stock Screen Using Range, Volume, Opening Gap, and Profitability

Summary

The document proposes screening Chinese-listed stocks for a price range greater than 1, current trading volume above 10,000 lots, a higher open, market capitalization below 10 billion yuan, and positive profits. It frames range and volume as signs of activity, the opening gap as a possible sign of strength, and profitability and size as basic company filters. It also suggests adding industry, broader market and policy conditions, marketing, and product sales to assess candidates more fully.

The page supplies a formula reference and a Python example, but they do not clearly implement the stated rules consistently: the code’s opening-price comparison appears to screen against the prior close in the opposite direction from a higher open, and its volume check uses a maximum over retrieved history. The document gives no backtest results, return estimates, or detailed operational rules. It warns that small companies can carry higher risk and that the screen omits important market and business factors, so the criteria are candidate filters rather than a demonstrated strategy.

Key ideas

• The proposed screen combines price range, trading volume, opening price, market capitalization, and profitability filters.
• The document recommends considering industry, market risk, policy, marketing, and product sales as additional context.
• The Python example’s opening-price comparison appears inconsistent with the stated higher-open condition.
• No performance evidence is supplied, and the screen omits factors that can materially affect company risk.
