NYSE Trading Floor re-opening improves market quality

May 28, 2020

The NYSE Trading floor partially re-opened on Tuesday, May 26, allowing Floor Brokers an opportunity to resume their business operations (with reduced headcount and restrictions in place to enforce social distancing and other safety protocols).

Floor Broker D Orders are Back in the Closing Auction

Floor Brokers have fueled the success of the NYSE Closing Auction, resulting in unrivaled liquidity and execution quality. Investors have swiftly resumed trading with Floor Brokers: D Orders, a flexible order type available only via the Floor, accounted for 30% of total Closing Auction volume on May 27.

Auction Consistency

As auctions once again include this valuable source of liquidity, we have seen improvement in auction execution quality. NYSE Closing Auctions regularly price stocks near their end-of-day volume-weighted average trading price, and the percentage of Closing Auctions doing so have gone up even further this week with the return of Floor Brokers.

NYSE’s Opening Auction quality has also seen an uptick this week, with the return of the Floor. Given the first minutes of trading after the open are usually the most volatile time of day, auction quality can be measured by how closely the open price tracks in line with subsequent trading. NYSE consistently excels at open pricing, and the Floor’s return has only improved this metric.

Why This Matters

The Trading Floor is quickly resuming its critical function in the NYSE Market Model. This will help improve market quality and liquidity, particularly during critical trading events such as the MSCI index rebalances this Friday, May 29.

In 2022, floor traded a higher put premium relative to call but a much lower put premium in 2023.
