A Unified Factor and Asset-Class Framework for Strategic and Tactical Allocation

Summary

The article describes a framework that links macroeconomic and style factors with traditional asset-class allocation. It proceeds from selecting factors and estimating asset exposures to building factor-mimicking portfolios, forecasting their returns, optimizing factor weights, deriving implied asset-class expected returns, and constructing an investable portfolio. Short-term exposures support tactical allocation, while longer estimation windows and averaged exposures are used for strategic allocation. The framework also allows quantified discretionary views and asset-specific return drivers to enter expected-return estimates.

An illustrative study uses a set of US and emerging-market equities, bonds, commodities, and cash, with growth, inflation, real rates, momentum, and volatility among its factors. It uses historical averages for factor-return forecasts and compares strategic, tactical, and discretionary-enhanced portfolios over a limited historical period. The reported results are presented as a proof of concept, not evidence of durable outperformance. The approach depends on reliable factor and asset forecasts, and the article notes that factor selection, residual return patterns, and changing relationships can affect its usefulness.

Key ideas

• The framework converts asset allocation into factor allocation and then maps optimized factor exposures back to asset expected returns.
• It estimates separate short-term and long-term exposures to support tactical and strategic decisions.
• Factor-mimicking portfolios make otherwise indirect factor exposures investable and measurable.
• Quantified discretionary views and asset-specific effects can supplement systematic factors.
• The example uses historical mean forecasts and a short evaluation period, limiting conclusions about robustness.
