RSI, Aggressive-to-Passive Volume, and Small-Capitalization Stock Screening

Summary

This A-share screening proposal combines RSI below 65, an external-to-internal volume ratio above 1.3, and a circulating-capitalization limit. The article’s stated final rule sets that limit at 5.5 billion shares, while a later note describes the criterion using circulating market value instead. It presents the combination as a way to mix technical and trading-activity signals with company size, but supplies no test results or evidence that the screen identifies undervalued stocks or future growth.

The note says capitalization alone does not determine valuation and highlights market perception and thematic interest as additional influences. It also observes that smaller-capitalization stocks may be more volatile and vulnerable to manipulation. Suggested improvements include adding profitability, growth, investment-value, industry, and market-rotation measures, with different treatment for large and small stocks. The example implementation does not directly establish the stated external-to-internal volume ratio, so the signal and capitalization units need to be verified before use.

Key ideas

• The proposed screen combines RSI below 65, an external-to-internal volume ratio above 1.3, and a capitalization constraint.
• The article gives inconsistent descriptions of the capitalization constraint, using shares in one place and market value elsewhere.
• No backtest or other performance evidence is reported.
• Small-capitalization stocks can bring greater volatility and manipulation risk.
• Fundamental, industry, and market-rotation measures are suggested as additional filters.
