A Monthly China A-Share Strategy Ranking Stocks by Float Market Cap

Summary

This strategy selects China A-shares by circulating market capitalization, removes suspended and specially treated stocks, and holds the smallest-ranked names in equal weights. The described implementation targets 50 stocks and rebalances on the first trading day of each month, buying and selling to match the new list. It uses daily data and open prices for orders, with the CSI 300 as its benchmark. The article connects the small-cap premise to the size effect discussed in the Fama-French framework, while describing possible growth and undervaluation benefits as rationale rather than demonstrated results.

The document warns that smaller companies can have lower liquidity, higher trading costs, and greater vulnerability to market or economic shocks. It suggests liquidity filters, risk controls, and combining size with growth or quality measures. No strategy performance figures or backtest results are supplied, and the described portfolio has no explicit stop-loss or take-profit rule. Its sample dates and platform configuration specify an implementation, not evidence that the approach will outperform.

Key ideas

• The article presents the size effect as rationale but does not provide performance evidence for this implementation.
