Screening Chinese Stocks by Profitability, Market Cap, RSI, and Fund Flows

Summary

This document describes a Chinese A-share screening idea that combines basic financial, technical, and capital-flow filters. It seeks companies with positive profits and market capitalization below 10 billion yuan, an RSI below 65, and positive main-fund net inflow on the previous day. The description also refers to a 2021 RSI condition, while the code calculates RSI from price data beginning in 2021 and checks its latest value.

The article argues that profitability and smaller size can help narrow the universe, while RSI and fund flows may identify stocks with room to rise. It gives no backtest, return data, or evidence that the filters predict performance. It flags possible financial-report manipulation and the subjectivity of technical signals, and suggests adding indicators and applying stop losses or position limits. The sample code has apparent implementation inconsistencies, including an undefined sorting field, so it should not be treated as a validated or ready-to-run strategy.

Key ideas

• The screen combines positive net profit with a market-cap ceiling of 10 billion yuan.
• It uses RSI below 65 and positive prior-day main-fund net inflow as additional filters.
• The article provides a rationale for the filters but no performance evidence or backtest results.
• Financial reporting quality and technical-signal uncertainty are cited as risks.
• The sample code appears incomplete and contains an undefined profit field.
