Investing in US Core Fixed Income with Macro and Style Factors
研究了在美国核心固定收益市场中，通过宏观因子和风格因子进行战略配置、时机选择和证券选择，构建优化组合以实现超额收益，信息比率达1.67。
The authors harvest factors—broad and persistent sources of returns—in US core fixed income in three ways. First, they take strategic over- and underweight positions in certain macro factors. Although strategic overweights to rates, or duration, and credit factors have historically resulted in outperforming fixed-income benchmarks, the authors find the long Treasury sector to be the most efficient way to capture rates exposure, and short-duration corporate bonds maximize risk-adjusted returns for credit exposure. Second, the authors time the allocation to rates and credit factors, along with changing high-yield and mortgage exposures. Third, the authors use style factors to select securities. They incorporate a value tilt in Treasuries and value and quality factors in investment-grade and high-yield sectors. Incorporating factors in these ways and building an optimized portfolio to control for deviations relative to the market index resulted in an information ratio of 1.67 over the period of January 2007 to March 2021.
