A China Stock Screen Combining Buying Activity, Turnover, and Limit-Ups

Summary

The post proposes a short-term screen for Chinese stocks using reported buying activity, prior-day turnover, and the number of limit-up sessions over the preceding ten days. It interprets stronger buying activity, active trading, and repeated limit-ups as signs of interest and recent price strength. It then adds valuation filters, recommending price-to-earnings below 30 and price-to-book below 2, and suggests considering liquidity and additional factors.

The document discusses possible risks such as overheated expectations and speculative price increases, but it provides no backtest, performance evidence, or clear definitions for several inputs. Its sample data workflow does not clearly implement the stated lookback and screening logic, so the code should not be treated as a validated reproduction. The thresholds are presented as a screening idea rather than a demonstrated source of returns.

Key ideas

• The screen combines buying-activity data, prior-day turnover, and recent limit-up frequency.
• The proposed filters aim to identify stocks with active trading and strong recent price movement.
• The final suggested screen adds price-to-earnings and price-to-book limits.
• The post flags overheating and speculative price increases as risks.
• No backtest is provided, and the sample workflow does not clearly implement all stated criteria.
