Risk and Return in Fixed-Income Arbitrage: Nickels in Front of a Steamroller?
分析了几种常用固定收益套利策略的风险与回报特征，发现需要更多智力资本的策略在控制市场风险后仍能产生显著正阿尔法，且回报呈正偏态，表明套利并非简单的“压路机前捡镍币”。
We conduct an analysis of the risk and return characteristics of a number of widely used fixed-income arbitrage strategies. We find that the strategies requiring more “intellectual capital” to implement tend to produce significant alphas after controlling for bond and equity market risk factors. These positive alphas remain significant even after taking into account typical hedge fund fees. In contrast with other hedge fund strategies, many of the fixed-income arbitrage strategies produce positively skewed returns. These results suggest that there may be more economic substance to fixed-income arbitrage than simply “picking up nickels in front of a steamroller.”
