Betting against Beta with Bonds: Worry or Love the Steepener?

摘要

Although "betting against beta" with government bonds (BABgov) seems profitable, questions remain. First, to what extent are BABgov profits an anomaly? Previous studies do not address routine valuation frameworks, such as term-structure models or principal components analysis. Second, "low" in low-risk investing refers to the second, not third, moment of returns, and prior research does not address coskew preferences. To consider the third question breadth I examine 20 non-US markets. On balance, BABgov is found to produce alpha, but primarily for the United States and with substantial systematic risk. Investors should follow BABgov cautiously.
