A Chinese Stock Screen Combining Recent Limit-Ups and Fundamental Filters
Summary
The document describes a Chinese equity screening idea that ranks stocks by capital-flow strength, then selects companies with no losses, market capitalization below a stated threshold, and more than two limit-up sessions in the recent ten-day window. It proposes adding valuation and trend filters: price-to-earnings below 30, price-to-book above 1, and price above its 20-day moving average. The intended logic combines recent price momentum and flow with basic profitability, size, valuation, and trend conditions.
The post cautions that this approach may overemphasize short-term performance and cannot reliably predict future returns. It suggests valuation ratios and moving averages as possible additions, but supplies no backtest, portfolio construction rules, transaction-cost analysis, or evidence that the filters improve results. The code example uses a fixed list of stock identifiers and simplified data fields, so it does not implement the full stated screening logic. The strategy is therefore a screening proposal rather than a validated trading system.
Key ideas
- The screen prioritizes stocks by reported capital-flow strength and recent limit-up frequency.
- It combines momentum conditions with profitability and a market-capitalization ceiling.
- Suggested refinements add price-to-earnings, price-to-book, and moving-average filters.
- The post provides no backtest or evidence that these conditions predict returns.
