A-Share Screen for High Amplitude, Smaller Float, and Low Share Price

Summary

This note proposes an A-share screen combining three filters: amplitude above 1%, tradable shares no greater than 5.5 billion, and share price below 12 yuan. It presents these as a way to focus on stocks with larger recent movement, a relatively small float, and a lower nominal share price. The sample formulas intersect the conditions, then rank qualifying names by turnover and select a subset.

The article cautions that the screen omits company financials, business fundamentals, and growth prospects, and that market conditions or company-specific events can affect the selected stocks. It suggests adding financial and industry analysis and reviewing the rules as conditions change. No historical returns, benchmark comparison, or risk-adjusted results are given, so the rationale remains an untested screening hypothesis. Low share price alone does not establish that a stock is inexpensive, and a small float or high amplitude can accompany substantial risk. The code examples illustrate selection mechanics rather than demonstrate a validated investment process.

Key ideas

• The proposed screen combines amplitude above 1%, float of at most 5.5 billion shares, and price below 12 yuan.
• The example code ranks intersecting candidates by turnover before choosing a subset.
• The note recommends adding financial, industry, and growth analysis to the filters.
• No backtest or performance evidence is supplied, and low nominal price does not establish value.
