英文摘要:
We analyze a proprietary dataset of trades by a single asset manager, comparing their price impact with that of the trades of the rest of the market. In the context of a linear propagator model we find no significant difference between the two, suggesting that both the magnitude and time dependence of impact are universal in anonymous, electronic markets. This result is important as optimal execution policies often rely on propagators calibrated on anonymous data. We also find evidence that in the wake of a trade the order flow of other market participants first adds further copy-cat trades enhancing price impact on very short time scales. The induced order flow then quickly inverts, thereby contributing to impact decay.

中文摘要:
我们分析单个资产管理公司的专有交易数据集,将其价格影响与市场其他交易的价格影响进行比较。在线性传播模型的背景下,我们发现两者之间没有显著差异,这表明影响的大小和时间依赖性在匿名电子市场中都是普遍存在的。这一结果很重要,因为最佳执行策略通常依赖于在匿名数据上校准的传播器。我们还发现,有证据表明,在一次交易之后,其他市场参与者的订单流首先增加了进一步的抄袭交易,从而在很短的时间范围内增强了价格影响。然后,诱导的有序流迅速反转,从而导致冲击衰减。
