英文摘要:
We model the impact costs of a strategy that trades a basket of correlated instruments, by extending to the multivariate case the linear propagator model previously used for single instruments. Our specification allows us to calibrate a cost model that is free of arbitrage and price manipulation. We illustrate our results using a pool of US stocks and show that neglecting cross-impact effects leads to an incorrect estimation of the liquidity and suboptimal execution strategies. We show in particular the importance of synchronizing the execution of correlated contracts.

中文摘要:
通过将之前用于单一工具的线性传播模型推广到多元情况,我们对交易一篮子相关工具的策略的影响成本进行了建模。我们的规范允许我们校准没有套利和价格操纵的成本模型。我们使用一组美国股票来说明我们的结果,并表明忽视交叉影响会导致对流动性的错误估计和次优执行策略。我们特别说明了同步执行相关合同的重要性。
