Screening Recent Top-List Stocks by Volatility and Circulating Market Value

Summary

This document presents a Chinese stock screen requiring a prior-day appearance on the Longhubang trading activity list, a price amplitude above 1, and circulating market value above 200 million yuan. It describes amplitude as a measure of short-term movement and treats top-list inclusion as a signal of potential trading interest. Formula and Python examples outline how to combine the conditions, although the examples use specified trading dates and would need adaptation for other dates and data sources.

The article characterizes the approach as a way to identify short-term opportunities, but supplies no backtest or evidence of returns. Its explanation also cautions that the rules are simple, market value does not establish profitability, and changing market conditions can make short-term results unstable. It suggests adding technical and fundamental filters and tailoring rules to market or industry conditions, without demonstrating that these changes improve the screen.

Key ideas

• The screen combines prior-day Longhubang inclusion, amplitude above 1, and circulating market value above 200 million yuan.
• The article interprets amplitude and list inclusion as indicators of short-term activity.
• Its examples use fixed dates and require adjustment for current data.
• No backtest or performance evidence is provided.
• The document warns that market value alone does not establish company profitability.
