I watched the market go haywire on this day. Attentive people made a cool buck or two as dislocations arose. What's crazy is that there were already rules in place to prevent stuff like this from happening - namely the Market Access Rule https://www.sec.gov/news/press/2010/2010-210.htm https://www.sec.gov/news/press/2010/2010-210.htm which was in place in 2010. When the dust settled, Knight sold the entire portfolio over via a blind portfolio bid to GS. Was a couple $bn gross portfolio. I think they made a pretty penny on this as well.
