Chinese Stock Screen Using Ten-Day Returns, RSI, and Main-Fund Flow

Summary

This Chinese A-share screening idea combines three conditions: a positive ten-day return below 35%, a 14-period RSI below 65, and positive main-fund net inflow on the previous day. The accompanying description frames the return band and RSI as technical filters, with fund flow as an additional selection criterion. It says selected stocks can be ranked by technical indicators and includes a Python example intended to implement the screen.

The article cautions that a stock meeting the return condition may still be in a broader downtrend and only have experienced a short-term rebound. It suggests adding company fundamentals and risk controls such as stop-loss levels, but supplies no backtest, transaction-cost analysis, or evidence that the screen is profitable. There is also a mismatch in the material: the stated logic refers to RSI in 2021, while the sample code computes RSI from the latest available series. The screening rules should therefore be treated as an illustrative strategy description, not a validated signal.

Key ideas

• The screen selects stocks with ten-day returns above zero and below 35%.
• It requires a 14-period RSI below 65 and positive prior-day main-fund net inflow.
• The article identifies short-term rebounds within a larger downtrend as a risk.
• It recommends considering fundamentals and risk controls, but provides no validated performance evidence.
• The described 2021 RSI condition differs from the latest-series RSI calculation in the sample.
