摘要翻译:
本文描述了一个具有Barra极端风险的缺口优化问题的实证研究。我们使用Barra风格因子(价值、增长、动量等)比较美国、英国和日本股票市场的最小缺口和最小方差投资组合。我们发现,在1985-2010年期间,最小化缺口通常比最小化方差改善业绩,尤其是在市场低迷时期。亏空的表现优于亏空是由于直觉上倾向于价值等保护性因素,而远离增长和势头等侵略性因素。衡量总体不对称性而不是极端损失的缺口是最大的表现。

英文摘要:
This paper describes an empirical study of shortfall optimization with Barra Extreme Risk. We compare minimum shortfall to minimum variance portfolios in the US, UK, and Japanese equity markets using Barra Style Factors (Value, Growth, Momentum, etc.). We show that minimizing shortfall generally improves performance over minimizing variance, especially during down-markets, over the period 1985-2010. The outperformance of shortfall is due to intuitive tilts towards protective factors like Value, and away from aggressive factors like Growth and Momentum. The outperformance is largest for the shortfall that measures overall asymmetry rather than the extreme losses.
