Fund Selection and Style Rotation Using Manager Skill and Fund Flows

Summary

This report analyzes Chinese active equity funds using Fama-French and Treynor-Mazuy models to separate market timing, stock selection, and style allocation. It reports that positive stock-selection ability was more common than persistent market-timing skill, with selection more evident in rising markets and some timing ability in falling markets. The authors use historical selection ability to choose managers for a fund-of-funds portfolio and use changes in aggregate fund style allocations to build a style-rotation approach.

The rotation method treats shifts in managers’ allocations as a momentum signal for relative style strength, illustrated by switching between large-cap and smaller-company indexes. The text reports correlations between allocation changes and relative style returns, alongside historical portfolio returns, drawdown, and trade statistics. These are findings presented by the report, not independently verified results; the extract gives limited information on implementation, costs, robustness, or out-of-sample validation. Its claims may depend on the sample period and the quality and timing of holdings data.

Key ideas

• The report uses factor and timing models to assess active fund managers’ stock selection and market timing.\nIt finds positive stock-selection ability more often than persistent market-timing ability in the studied funds.\nHistorical manager stock-selection skill is used as a criterion for a fund-of-funds portfolio.\nChanges in aggregate fund style allocations are treated as a momentum signal for style rotation.\nThe reported historical results do not establish robustness beyond the stated sample or account fully for implementation costs.
