Industry Fundamental Filters Combined with Multi-Factor Equity Portfolios

Summary

This research summary describes a Chinese equity approach that first screens stocks within broad industry groups using selected fundamental indicators, then combines the resulting preferred-stock universe with a multi-factor framework. It discusses a broad-market portfolio and enhanced portfolios benchmarked to the CSI 500 and CSI 300. The industry-based universe is compared with one selected using a composite quality factor, with the summary reporting higher information ratio and lower drawdown for the former, alongside strongly correlated return paths.

For the period from 2011 through March 2019, the document reports annualized excess return and information ratio for the broad-market portfolio, as well as excess return, information ratio, and maximum relative drawdown for the two benchmark-enhanced portfolios. It says results improved notably in 2017 and 2018. These are reported historical results, not proof of future performance. The authors identify in-sample overfitting in industry-level indicator selection and the possibility that fundamental signals may lose effectiveness.

Key ideas

• The method screens stocks using selected fundamentals within broad industry groups before applying a multi-factor portfolio process.
• The research covers a broad-market portfolio and CSI 500 and CSI 300 enhanced portfolios.
• The industry-selected universe is reported to have slightly better information ratio and smaller drawdown than a composite-quality-factor universe.
• The reported backtest spans 2011 through March 2019 and includes performance measures for the portfolios.
• Industry-specific indicator selection may overfit the sample, and fundamental signals may stop working.
