Screening Chinese Stocks by Volatility and Institutional Net Buying

Summary

This Chinese equity screening idea combines three filters: daily price amplitude above a threshold, positive institutional net buying, and a high rank in large-order net flow. The rationale is to find shares with active price movement and signs of institutional or large-trader interest. The post gives example indicator logic and Python-style pseudocode for combining the conditions and sorting the resulting candidates by turnover.

The author cautions that this is a short-term, market-sensitive screen that omits company fundamentals and longer-term prospects. Large-order net flow is a relative measure and may be distorted by unusual events or speculative activity. Suggested refinements include adding profitability and valuation measures, industry and company context, and portfolio risk controls such as diversification. The document offers no performance results or evidence that the screen predicts returns. Its code is presented as an example requiring adjustment, so the exact data definitions, thresholds, and ranking behavior would need validation before use.

Key ideas

• The screen combines price amplitude, positive institutional net flow, and a large-order net-flow ranking.
• Its stated goal is to identify active shares attracting institutional or substantial order flow.
• The post provides example screening logic but reports no backtest or performance evidence.
• Relative net-flow rankings can be affected by unusual conditions and should not be treated as proof of investment quality.
• Fundamental filters and risk controls are suggested as ways to broaden and constrain the screen.
