The data indicated that during July 5-8, program trading amounted to 55.8 percent of NYSE average daily volume of 1,501.2 million shares, or 837.1 million shares a day.
Program trading encompasses a wide range of portfolio-trading strategies involving the purchase or sale of a basket of at least 15 stocks with a total value of $1 million or more. Program trading is calculated as the sum of the shares bought, sold and sold short in program trades. The total of these shares is divided by total reported volume.
This is not the only way to measure program trading. Three alternatives for July 5-8 would be to:
- examine buy programs as a percentage of total purchases (27.8 percent);
- examine sell programs as a percentage of total sales (28.0 percent);
- examine program purchases and sales as a percentage of total purchases and sales (27.9 percent).
For the third quarter of 2005, the NYSE’s program-trading report includes profiles of program trading whenever the Dow Jones Industrial Average moves 210 points or more in a single direction during any one-hour period. During July 5-8, there were no such periods.
In all markets, program trading by member firms averaged 1,426.8 million shares a day during July 5-8. About 58.7 percent of program trading took place on the NYSE, 0.6 percent in non-U.S. markets and 40.7 percent in other domestic markets, including Nasdaq, the American Stock Exchange and regional markets.
In aggregate, program volume executed on the NYSE by firms as agent, for non-member customers, amounted to 54.3 percent during July 5-8. Program volume executed as principal, for their own accounts, amounted to 41.1 percent of program volume.
Another 4.6 percent was designated as customer facilitation, in which a member firm established or liquidated a principal position to facilitate a program order initiated by a customer.
Of the five member firms reporting the most program trading activity on the NYSE, UBS Securities, LLC. and Lehman Brothers, Inc. executed most of their program trading as principal for their own accounts. Morgan Stanley & Co. Inc., Goldman, Sachs & Co. and Deutsche Bank Securities executed most of their program trading activity for customers, as agent.
During July 5-8, 12.4 percent of program volume executed by NYSE member firms related to index arbitrage. Index arbitrage is defined as the purchase or sale of a basket of stocks in conjunction with the sale or purchase of a derivative product such as stock-index futures, to profit from the price difference between the basket and the derivative product.
Less than 0.1 percent involved derivative product-related strategies (besides index arbitrage) that are subject to Rule 80A. The rule provides that derivative-related program strategies be executed only in a stabilizing manner after the DJIA moves 210 points or more from the previous day’s close.
In addition to index arbitrage, such strategies include customer facilitations, liquidation of facilitations, index substitutions, liquidation of error accounts, risk modifications, and liquidation of exchange-for-physicals stock positions.
All other types of portfolio-trading strategies combined accounted for 87.6percent of member firms’ program-trading volume during July 5-8.
