英文摘要:
Both the scientific community and the popular press have paid much attention to the speed of the Securities Information Processor, the data feed consolidating all trades and quotes across the US stock market. Rather than the speed of the Securities Information Processor, or SIP, we focus here on its accuracy. Relying on Trade and Quote data, we provide various measures of SIP latency relative to high-speed data feeds between exchanges, known as direct feeds. We use first differences to highlight not only the divergence between the direct feeds and the SIP, but also the fundamental inaccuracy of the SIP. We find that as many as 60 percent or more of trades are reported out of sequence for stocks with high trade volume, therefore skewing simple measures such as returns. While not yet definitive, this analysis supports our preliminary conclusion that the underlying infrastructure of the SIP is currently unable to keep pace with the trading activity in today\'s stock market.

中文摘要:
科学界和大众媒体都非常关注证券信息处理器的速度,这是整合美国股市所有交易和报价的数据馈送。与其说是证券信息处理器(SIP)的速度,不如说是它的准确性。根据交易和报价数据,我们提供了与交易所之间的高速数据馈送(称为直接馈送)相关的各种SIP延迟度量。我们使用第一个差异不仅强调了直接馈送和SIP之间的差异,而且还强调了SIP的根本不精确性。我们发现,对于成交量较高的股票,多达60%或更多的交易是按顺序报告的,因此偏离了回报等简单指标。虽然尚未确定,但该分析支持我们的初步结论,即SIP的基础设施目前无法跟上当今股市的交易活动。
