英文摘要:
  For a functionally generated portfolio, there is a natural decomposition of the relative log-return into the log-change in the generating function and a drift process. In this note, this decomposition is extended to arbitrary stock portfolios by an application of Fisk-Stratonovich integration. With the extended methodology, the generating function is represented by a structural process, and the drift process is subsumed into a trading process that measures the profit and loss to the portfolio from trading.

中文摘要:
对于功能生成的投资组合,相对对数收益自然分解为生成函数中的对数变化和漂移过程。在本文中,通过应用Fisk-Stratonovich积分,将此分解扩展到任意股票组合。在扩展的方法中,生成函数由一个结构过程表示,漂移过程被包含到一个交易过程中,该交易过程衡量投资组合的交易损益。
