非流动性市场中的最优交易执行

Optimal Trade Execution in Illiquid Markets

Erhan Bayraktar, Mike Ludkovski

摘要:

本文研究了具有离散订单流的金融市场的最优交易执行策略。代理人有一个有限的清算期限,必须尽量减少价格的影响,给定一个随机数量的传入交易对手。在订单流$N$为Poisson过程的假设下,对最优动态执行策略的性质和计算进行了全面的分析。扩展,其中(a)$N$是一个完全观察到的政权切换泊松过程;和(b)$N$是一个马尔可夫调制的复合泊松过程驱动的隐马尔可夫链,也被认为是。我们推导并比较了这三种情况下的性质,并用计算实例说明了我们的结果。

英文摘要:

We study optimal trade execution strategies in financial markets with discrete order flow. The agent has a finite liquidation horizon and must minimize price impact given a random number of incoming trade counterparties. Assuming that the order flow $N$ is given by a Poisson process, we give a full analysis of the properties and computation of the optimal dynamic execution strategy. Extensions, whereby (a) $N$ is a fully-observed regime-switching Poisson process; and (b) $N$ is a Markov-modulated compound Poisson process driven by a hidden Markov chain, are also considered. We derive and compare the properties of the three cases and illustrate our results with computational examples.
