Chinese Stock Screening with Buying Activity and Short-Term Gains

Summary

This Chinese stock-screening example combines three filters: reported position increases above 5%, a daily rise above 1%, and a positive return below 35% over the prior ten days. It presents the combination as a way to find mainland listed shares with recent buying activity and upward price movement. The accompanying explanation interprets increased positions as institutional buying and the price filters as evidence of a recent upward trend.

The post warns that reported buying may not be rational or sufficient to support a valuation, and that recent price strength can reverse or reflect market sentiment. It suggests adding valuation ratios, industry, and market capitalization to refine the screen. No performance results or empirical validation are provided. The sample implementation is schematic: its data retrieval function is left unfinished, and its later filters do not clearly preserve the stated ten-day return condition. The thresholds and data definitions therefore need clarification before the screen can be reproduced or evaluated.

Key ideas

• The screen requires position increases above 5%, a daily gain above 1%, and a positive ten-day return below 35%.
• The post interprets increased positions as potential institutional buying, but this does not establish that the buying is informed or sustainable.
• Recent upward movement can reverse, and market sentiment can affect short-term returns.
• The author suggests adding valuation, industry, and market-capitalization filters.
• The example provides no backtest results, and its sample logic does not clearly implement every stated condition.
