Screening Chinese Stocks by Turnover, Recent Returns, and Limit-Ups

Summary

This document outlines an A-share stock screen using three market-based conditions: turnover between 3% and 12%, a positive return below 35% over ten days, and at least one limit-up event during the prior 25 days. It frames these filters as a way to identify stocks with recent activity and positive price performance. An accompanying code example also mentions excluding some listings and stocks, though its implementation details are not a clean or complete translation of the stated rule.

The article warns that the approach relies heavily on market attention and reactions to company news. It notes that stocks can fall after limit-up moves and that the screen does not assess company value or risk in depth. It recommends supplementing price and turnover conditions with financial health and profitability measures. No backtest, sample, or evidence of returns is presented, so the screening idea remains an unvalidated selection heuristic.

Key ideas

• The stated screen combines 3%–12% turnover with a positive ten-day return below 35%.\nA candidate must also have recorded a limit-up event in the preceding 25 days.\nThe rule selects for recent market activity and price strength rather than intrinsic value.\nThe article warns that post-limit-up prices can decline and that market attention can be unreliable.\nIt recommends adding financial measures, but provides no evidence that this improves performance.
