Excellent article by my colleague Choey Li describing the impact of large orders in the NYSE auction during the last five minutes of trading. Hint: even about 0.5% of CADV will not have persistent price impact in the last three minutes. nyse.com/data-insights/…
My latest NYSE Data Insights article discusses who is trading all those low-prices stocks. nyse.com/data-insights/… #NYSE #StockMarket
Proud to work for the NYSE.
My colleague Choey Li shows how market quality has improved for five recent ETF transfers to the NYSE. #ETF #NYSE #StockMarket nyse.com/data-insights/…
Raising opportunity. It’s what we do.

This was an irrational decision.
See how the NYSE Russell Rebalance closing auction out performed the competition. linkedin.com/posts/nyse_nys…
Today's Russell Reconstitution lived up to expectations - NYSE traded 2.3 billion shares at the close, the 4th largest closing auction of all time.
