英文摘要：
  We introduce a pathwise approach to analyze the relative performance of an equity portfolio with respect to a benchmark market portfolio. In this energy-entropy framework, the relative performance is decomposed into three components: a volatility term, a relative entropy term measuring the distance between the portfolio weights and the market capital distribution, and another entropy term that can be controlled by the investor by adopting a suitable rebalancing strategy. This framework leads to a class of portfolio strategies that allows one to outperform, in the long run, a market that is diverse and sufficiently volatile in the sense of stochastic portfolio theory. The framework is illustrated with several empirical examples.

中文摘要：
我们引入一种路径方法来分析股票投资组合相对于基准市场投资组合的相对表现。在这个能量熵框架中，相对绩效被分解为三个组成部分：波动率项、衡量投资组合权重与市场资本分布之间距离的相对熵项，以及投资者可以通过采取适当的再平衡策略来控制的另一个熵项。这一框架引出了一类投资组合策略，从长远来看，它能让一个人超越一个在随机投资组合理论意义上具有多样性和足够波动性的市场。通过几个实证例子说明了该框架。
