Screening Chinese Stocks by Volatility, Float Size, and Volume Growth

Summary

The document describes a Chinese equity screen that combines daily price amplitude above 1%, a circulating share count no greater than 5.5 billion, and a day-over-day increase in volume above 5%. It explains the intended rationale: price movement may indicate short-term trading activity, smaller floats may offer greater upside and risk, and rising volume may signal increased buying interest. It also gives example calculations and combines the three filters to identify stocks passing all of them.

The article cautions that volume changes can be noisy and that fixed thresholds may perform poorly across different market conditions and stock characteristics. Short-term signals can also miss longer-term trends and company fundamentals. It recommends adapting the criteria to the market and combining them with other indicators. No backtest, return data, or evidence of predictive performance is provided, so the screen should be treated as a proposed selection rule rather than a demonstrated strategy. The code examples also differ slightly in whether the volume threshold is inclusive.

Key ideas

• The screen requires price amplitude above 1%, circulating shares at or below 5.5 billion, and volume growth above 5%.
• The three filters are combined so a stock must pass each condition to be selected.
• The article associates rising volume with potential capital inflows but does not validate that interpretation empirically.
• Fixed thresholds and short-term signals may be unreliable across changing markets and can overlook longer-term fundamentals.
