Is the era of the human trading pit finally coming to an end?

While most exchanges have transitioned to algorithmic systems, the NYSE still maintains open outcry floor trading. This video examines the debate over whether human floor brokers are essential or merely obsolete.

The video explores two contrasting academic perspectives on market efficiency. One study, "Vestigeral Tails" by Edwin Hu and Dermot Murphy, suggests that the NYSE's 4 p.m. auctions ran more smoothly after the floor closed, though the NYSE has challenged these findings.

Conversely, research by Brogaard, Ringgenberg, and Rösch suggests that removing floor traders degrades market quality. Their analysis indicates that the suspension of floor trading correlates with increased volatility, higher effective spreads, and more frequent pricing errors, even in an age dominated by electronic trading.
