英文摘要:
This paper investigates the dependence of functional portfolio generation, introduced by Fernholz (1999), on an extra finite variation process. The framework of Karatzas and Ruf (2017) is used to formulate conditions on trading strategies to be strong arbitrage relative to the market over sufficiently large time horizons. A mollification argument and Komlos theorem yield a general class of potential arbitrage strategies. These theoretical results are complemented by several empirical examples using data from the S&P 500 stocks.

中文摘要:
本文研究了Fernholz(1999)提出的函数投资组合生成对额外有限变分过程的依赖性。Karatzas和Ruf(2017)的框架用于制定交易策略的条件,以便在足够大的时间范围内相对于市场进行强套利。一个缓和论证和Komlos定理产生了一类普遍的潜在套利策略。这些理论结果通过使用标准普尔500指数股票数据的几个实证例子加以补充。
