Selecting a Style Strategy by Return Correlation for Portfolio Rotation

Summary

This assignment outlines a style-rotation process built from three stock strategies: small-capitalization, below-book-value, and oversold-rebound approaches. After backtesting each strategy, it proposes saving the return and position series, then comparing each strategy’s returns with a factor-return table. At each rebalance date, the process selects the strategy with the highest correlation and uses that strategy’s holdings for the rotating portfolio.

The document gives the workflow but no implementation detail about the correlation measure, estimation window, rebalance schedule, portfolio weighting, or factor definition. It also reports no test results. Since strategy selection depends on measured correlations, the method’s behavior will depend on how those correlations are estimated; the description does not explain safeguards against overfitting or look-ahead bias. The idea is presented as an assignment outline, not as evidence of a validated investment strategy.

Key ideas

• The proposed rotation compares three equity strategies: small-capitalization, below-book-value, and oversold rebound.
• It calls for storing each strategy’s backtested returns and holdings.
• At each rebalance, it selects the strategy with the highest correlation to factor returns.
• The selected strategy’s positions become the holdings for the rotating portfolio.
• No performance results or safeguards for correlation estimation are specified.
