A Volatility and Large-Order Flow Screen for Chinese Stocks

Summary

This stock selection proposal combines elevated price range, a recent large daily gain, and a measure linking price change with net volume attributed to very large orders. The rationale is to find shares showing volatility, upward momentum, and buying pressure. The document then suggests adding relative volume filters, ranking the price-change and volume measure against its history, and incorporating fundamentals, valuation, sector context, and other technical indicators.

The text flags risks from relying on a narrow set of quantitative signals and from noisy large-order activity that may be distorted by unusual trades. It offers indicator formulas and sample implementations, but does not report a backtest, transaction costs, benchmark comparison, or evidence that the screen predicts returns. Several proposed refinements are placeholders for further work, so this should be read as an exploratory screening idea rather than a validated trading strategy.

Key ideas

• The initial screen seeks volatile stocks with a recent sharp gain and positive large-order flow characteristics.
• The proposed refinements add relative volume and historically high price-change-volume readings.
• Fundamental, valuation, sector, and technical signals are suggested as additional filters.
• The document warns that isolated indicators may overlook important information and react to unusual orders.
• No backtest or performance evidence is provided for the proposed screen.
