Chinese Stock Screen Using Ten-Day Returns, Fund Flows, and Volume Ratio

Summary

This Chinese equity screen combines three short-term filters: a positive ten-day return below 35%, a high volume ratio, and strong net inflow attributed to major investors on the prior day. The article describes ranking both the volume ratio and prior-day net inflow among the top 100 stocks, then using the ten-day return band to constrain recent price performance. It presents these measures as proxies for trading activity, capital interest, and a stock’s recent advance.

The text gives qualitative explanations and risk discussion, but no complete executable selection rule, backtest, or outcome data. It notes that large flows do not ensure continued gains and that a positive recent return may coincide with elevated volatility. Suggested refinements include narrowing the rankings and return band, though the article’s optimization discussion is incomplete. The signals are short horizon and may be sensitive to data definitions and market conditions.

Key ideas

• The return filter requires a positive ten-day gain below 35%.
• The strategy ranks volume ratio and prior-day major-investor net inflow, each using a top-100 cutoff.
• The article treats activity and flow measures as proxies for market attention, not guaranteed forecasts.
• It warns that strong flows and recent gains can still coincide with volatility and losses.
• No complete backtest or performance evidence is provided, and the proposed refinements are partial.
