The Value of Floor Broker Executions

By Staff Reports

Electronic executions are credited with reducing transaction costs on U.S. equity markets. Now there is evidence that manual style-order handling may in some cases be better for investors. That's the conclusion of an academic study, which compares non-block trades handled by floor brokers on the American Stock Exchange, with its automated post execution reporting system (PER).

The authors are Puneet Handa, University of Iowa; Robert Schwartz, Baruch College, CUNY, and Ashish Tiwari, University of Iowa.

The study notes that, "trades handled by floor brokers have a significantly smaller realized half-spread than do PER trades (-3.06bps vs. 4.43 bps). This difference of 7.49 bps [basis points] is equivalent to a savings of 3.94 cents per share for an average priced stock on the Amex." The study contends that, based on the sample's floor trading volume, the monthly savings came to $4.36 million.
