Chinese Stock Screen for High Amplitude, an 18.5 Price, and Low Float

Summary

This Chinese stock-screening note proposes selecting shares with daily price amplitude above 1%, a closing price of exactly 18.5 yuan, and a float of no more than 5.5 billion shares. It presents the screen as a way to find active, volatile stocks with relatively limited tradable supply, and suggests sorting candidates by trading value. It also mentions adding market value, valuation, or MACD filters.

The note provides formula-style and Python examples, but the implementation has material inconsistencies: its formula uses a percentage-change field for the float condition, and the Python example sorts on trading volume even though the selected records do not include that field. The article offers no backtest or performance evidence, so the claimed potential benefits are not established. Its stated risks include subjective or unsuitable fundamental criteria; more broadly, an exact price threshold and a single-day amplitude screen may produce a narrow or unstable list. Treat it as a rough screening idea requiring data and logic validation, not as a tested trading strategy.

Key ideas

• The screen combines amplitude above 1%, a closing price of 18.5 yuan, and a float limit of 5.5 billion shares.
• It frames volatility and limited float as possible signs of activity or sensitivity to news.
• The note suggests adding market value, valuation, or MACD conditions.
• The sample implementations contain mismatches between the stated criteria and fields used.
• No backtest or evidence of profitability is provided.
