摘要

从 2021 年 12 月到 2022 年 6 月,我们在六个零售经纪账户中进行了 85,000 笔零售交易,以验证 Boehmer 等人的算法,该算法使用亚笔交易价格来识别和签署零售交易。该算法将 35% 的交易识别为零售交易,错误地签署了 28% 的识别交易,并对 30% 的股票进行了无信息的订单不平衡测量。我们修改了算法,使用报价价差中点来签署交易。报价中点法不会影响识别率,但会将签约错误率降至 5%,并为所有股票提供信息丰富的订单不平衡度量。

A (Sub)penny for Your Thoughts: Tracking Retail Investor Activity in TAQ

We placed 85,000 retail trades in six retail brokerage accounts from December 2021 to June 2022 to validate the Boehmer et al. algorithm, which uses subpenny trade prices to identify and sign retail trades. The algorithm identifies 35% of our trades as retail, incorrectly signs 28% of identified trades, and yields uninformative order imbalance measures for 30% of stocks. We modify the algorithm by signing trades using the quoted spread midpoints. The quote midpoint method does not affect identification rates but reduces the signing error rates to 5% and provides informative order imbalance measures for all stocks.
