A Chinese Stock Screen Combining Price Range, Volume, Gap, and Profitability
Summary
The document describes a daily Chinese-equity stock screen combining price action, trading activity, market capitalization, and profitability. The proposed filters require an intraday range above 1% relative to the prior close, market capitalization below 10 billion yuan, positive net profit across the most recent four quarters, current volume above 10,000 lots, and an open above the previous close. The selection rationale mixes technical conditions with basic financial screening.
It flags several limitations: a small-cap cutoff excludes larger companies, positive earnings alone do not establish business quality, and a higher open can reflect short-term sentiment. It suggests adding valuation or earnings measures and tailoring criteria by sector or industry. The document includes formula and Python examples, but provides no backtest, return data, transaction-cost analysis, or precise portfolio construction and exit rules. The screen is therefore a candidate-selection recipe, not evidence of a profitable strategy; implementation also depends on consistent definitions and current fundamental data.
Key ideas
- The screen combines intraday range, trading volume, market capitalization, quarterly profitability, and an upward opening gap.
- It limits candidates to companies below 10 billion yuan in market capitalization with positive net profit in each of the latest four quarters.
- The document warns that small-cap and positive-profit filters can exclude opportunities or oversimplify company quality.
- An opening gap may reflect short-term sentiment rather than durable company strength.
- It proposes adding valuation measures and adapting criteria to sectors, but supplies no backtest or exit method.
