Chinese Stock Screening with Amplitude, Market Capitalization, and Prior Low

Summary

This Chinese stock-screening idea selects shares with daily amplitude above 1, circulating market capitalization above 10 billion yuan, and a closing price above the previous day’s low. The stated rationale is to favor relatively active, larger companies whose latest close has held above a recent downside reference. It is framed as a short-term technical screen rather than a complete investment process.

The document acknowledges that the criteria omit company fundamentals and industry conditions, and recommends adding valuation, return, and sector information for a broader assessment. It includes formula and Python examples, but the Python example does not implement every stated filter: it checks the prior-low condition and market listing, but does not apply the amplitude or capitalization thresholds. No backtest or evidence of returns is reported, and the closing-price comparison alone does not establish a sustained upward trend.

Key ideas

• The screen combines daily amplitude, circulating market value, and the prior day’s low.
• Its stated thresholds are amplitude above 1 and circulating market capitalization above 10 billion yuan.
• The rationale is to combine activity and company size with a basic price condition.
• The document flags missing fundamental and industry analysis as limitations.
• The provided Python example omits the amplitude and market-capitalization filters.
