Using Capital Flow Ratios to Guide Equity Style Rotation
Summary
This Chinese research note proposes using capital flow ratios within style-factor portfolios to guide style rotation. It argues that raw inflow and outflow totals mostly move alongside prices, while flows measured against trading value or by period-over-period growth may better reveal changes in investor preference. The analysis considers net capital flows, margin financing balances, and Stock Connect flows, then forms six sub-strategies from different flow measures.
Because the Stock Connect history is shorter, the combined strategy equally weights style portfolios based on four of the other flow ratios. The note reports a backtest from May 2010 through June 2018, with 673.1% cumulative excess return and a 63.8% win rate; the maximum drawdown figure is truncated in the supplied text. Its latest cited allocation favors low liquidity, low valuation, and one-month reversal styles. These are historical results, not evidence of robustness across regimes, and the authors caution that the model may lack a firm economic rationale and can fail in extreme markets.
Key ideas
- Flow ratios within style portfolios may contain more information for rotation than aggregate inflow and outflow totals.
- The study considers net flows, margin balances, and Stock Connect flows using trading-value shares and growth rates.
- The combined strategy equally weights four flow-based style portfolios because Stock Connect data cover a shorter period.
- The reported historical backtest does not establish that the approach will work in other market conditions.
- The note flags model subjectivity and possible failure during extreme market changes.
