A-Share Screening with Afternoon Block Inflows and Position Growth

Summary

This note describes a Chinese stock screen built around three conditions: a reported increase in position share above 5%, large-order net inflow during the afternoon, and a 2021 time filter. It interprets the first two as signs of buying pressure and sustained capital inflow, then suggests adding profitability and valuation criteria such as earnings strength and price-to-earnings ratios.

The document gives no backtest, performance figures, or detailed definitions for the screening fields, and its sample data code does not implement all of the stated conditions. It cautions that these signals may not predict future performance or reflect intrinsic value, especially during sharp short-term price moves. The idea is therefore a heuristic screen rather than a demonstrated trading strategy.

Key ideas

• The screen combines a position-share increase above 5% with afternoon large-order net inflows.
• A 2021 date filter is included, though the document does not explain its precise purpose.
• The author suggests adding profitability and valuation measures to refine candidates.
• The document provides no performance evidence and warns that the signals may not capture future returns or fair value.
