英文摘要:
We report on the occurrence of an anomaly in the price impacts of small transaction volumes following a change in the fee structure of an electronic market. We first review evidence for the existence of a master curve for price impact on the Johannesburg Stock Exchange (JSE). On attempting to re-estimate a master curve after fee reductions, it is found that the price impact corresponding to smaller volume trades is greater than expected relative to prior estimates for a range of listed stocks. We show that a master curve for price impact can be found following rescaling by an appropriate liquidity proxy, providing a means for practitioners to approximate price impact curves without onerous processing of tick data.

中文摘要:
我们报告了电子市场费用结构发生变化后,小交易量的价格影响出现异常。我们首先回顾了约翰内斯堡证券交易所(JSE)存在价格影响主曲线的证据。在尝试在费用减少后重新估计主曲线时,发现与一系列上市股票的先前估计相比,小交易量交易对应的价格影响大于预期。我们表明,在通过适当的流动性代理进行重新缩放后,可以找到价格影响的主曲线,这为从业者提供了一种近似价格影响曲线的方法,而无需繁琐地处理刻度数据。
