A Chinese Stock Screen Combining Net Buying, Three Down Days, and Open Gains

Summary

This document proposes a mainland Chinese stock screen that combines a reported increase in holdings above 5%, three consecutive declining sessions, and a 9:25 a.m. price gain below 6%. It interprets the buying measure as evidence of inflows and the losing streak as a possible oversold condition, while the small early gain is treated as a low-attention signal. The post then adds market capitalization above 10 billion and price-to-earnings below 30, plus Bollinger and moving-average conditions, as possible refinements.

The rationale is qualitative; the document supplies no backtest, performance figures, or evidence that the conditions predict returns. It flags the chance of neglect and overvaluation, and suggests adding company and technical measures. The accompanying sample code does not faithfully implement the stated screen: its price-change conditions differ, and the indicator checks do not clearly match the final rules. Treat the proposal as an unvalidated screening idea, and verify data definitions, indicator calculations, and timing before evaluation.
