A Stock Screen Combining Daily Range, Afternoon Flows, and Annual Returns
Summary
The document describes a Chinese stock-selection screen combining three conditions: daily price amplitude above a threshold, afternoon large-order net inflow, and strong performance since the start of 2021. It gives an indicator formula reference and a Python example intended to retrieve stock data and filter candidates. The selected stocks are presented as a starting universe for further analysis, not as automatic buy recommendations.
The article warns that the screen uses only a few short-term signals and omits longer-term trends and company fundamentals. It recommends checking fundamentals, technical conditions, and policy factors, alongside risk controls and capital management. The explanation and code leave important details uncertain: the annual-return ranking condition is not clearly aligned with the stated top-30% criterion, and the flow and amplitude calculations may not implement the prose consistently. No backtest results or performance evidence are provided, so the method's effectiveness is unestablished.
Key ideas
- The screen combines price amplitude, afternoon large-order flow, and a return-ranking condition tied to 2021.
- The article provides formula and Python references for identifying candidate equities.
- Selected stocks require further fundamental, technical, and policy analysis.
- The screen omits longer-term market context and offers no backtest evidence.
