Chinese Stock Screening by Daily Range, Decline, and Revenue Growth

Summary

The post proposes a Chinese equity screen combining a daily price range threshold, a one-day decline bounded between roughly four and five percent, and revenue growth: 2021 revenue must exceed 2018 revenue by more than a stated ratio. Its example Python code also filters out names beginning with an asterisk and applies market capitalization, price-to-book, and price-to-earnings conditions. The written rule list and code do not fully align, so the implementation should not be assumed to reproduce the stated screen exactly.

The author characterizes the price conditions as technical signals and revenue growth as a fundamental signal. The post reports no backtest or return evidence. It acknowledges that revenue alone omits profitability and financial health, and cites liquidity, delayed signals, and selection errors as risks. It suggests considering sentiment and additional fundamentals, but provides no tested refinement.

Key ideas

• The proposed screen combines a daily price-range condition, a bounded daily decline, and multi-year revenue growth.
• The example code adds valuation and market-size filters beyond the stated core rules.
• The written criteria and sample implementation differ, so their outputs may not match.
• The post offers no performance evidence and notes that revenue growth alone omits other financial factors.
