考虑买卖价差交易成本的期货最优交易

文章 arXiv papers · 作者: Theodoros Tsagaris

总结

本文构建了离散时间下期货投资者终端财富期望效用最大化问题,并将其置于布朗市场框架中,介绍保证金、杠杆和滑点等期货交易实务概念。价格变化被表示为离散随机序列,而收益过程则由不可观测的漂移和布朗运动驱动。

交易成本通过买卖价差纳入模型;论文称其推导出显式的最优投资组合过程,并用对数效用说明该结果。论文还初步讨论了统计套利策略。所提供的描述没有给出推导过程、参数估计假设、数值示例或表现证据,因此有助于理解模型设定,却不足以判断解的稳健性或现实盈利能力。特别是,对不可观测收益驱动因素和价差成本的处理,可能限制该结果直接应用于实盘市场的程度。

核心观点

  • 该问题旨在离散时间期货市场中最大化终端财富的期望效用。
  • 模型使用不可观测的漂移和布朗运动表示期货收益。
  • 交易成本通过买卖价差建模。
  • 文中介绍保证金、杠杆和滑点等期货市场相关概念。
  • 论文给出了显式投资组合解,并以对数效用为例,但摘要未提供具体细节。

# Statistical Arbitrage and Optimal Trading with Transaction Costs in Futures Markets









We consider the Brownian market model and the problem of expected utility maximization of terminal wealth. We, specifically, examine the problem of maximizing the utility of terminal wealth under the presence of transaction costs of a fund/agent investing in futures markets. We offer some preliminary remarks about statistical arbitrage strategies and we set the framework for futures markets, and introduce concepts such as margin, gearing and slippage. The setting is of discrete time, and the price evolution of the futures prices is modelled as discrete random sequence involving Ito's sums. We assume the drift and the Brownian motion driving the return process are non-observable and the transaction costs are represented by the bid-ask spread. We provide explicit solution to the optimal portfolio process, and we offer an example using logarithmic utility.
