英文摘要：
We study dynamic optimal portfolio allocation for monotone mean--variance preferences in a general semimartingale model. Armed with new results in this area we revisit the work of Cui, Li, Wang and Zhu (2012, MAFI) and fully characterize the circumstances under which one can set aside a non-negative cash flow while simultaneously improving the mean--variance efficiency of the left-over wealth. The paper analyzes, for the first time, the monotone hull of the Sharpe ratio and highlights its relevance to the problem at hand.

中文摘要：
研究了一般半鞅模型中单调均值-方差偏好下的动态最优投资组合分配问题。借助这一领域的新成果，我们重新回顾了崔、李、王和朱（2012，MAFI）的工作，并充分描述了在何种情况下可以留出非负现金流，同时提高剩余财富的均值-方差效率。本文首次分析了夏普比的单调壳，并强调了它与当前问题的相关性。
