Program Trading Averaged 44.9 Percent of NYSE Volume During June 17-21, 2002

Date 27/06/2002

The New York Stock Exchange today released its weekly program-trading data submitted by its member firms. The report includes trading in all markets as reported to the NYSE for June 17-21, 2002.

The data indicated that during June 17-21, program trading amounted to 44.9 percent of NYSE average daily volume of 1,422.5 million shares, or 638.6 million shares a day. This included program trading associated with the June 21 quarterly expiration of stock-index options and futures.

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 June 17-21 would be to:

  • examine buy programs as a percentage of total purchases (23.2 percent);
  • examine sell programs as a percentage of total sales (21.7 percent);
  • examine program purchases and sales as a percentage of total purchases and sales or twice total volume (22.4 percent).
For the second quarter of 2002, 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 June 17-21, there were no such periods.

In all markets, program trading averaged 1,145.2 million shares a day during June 17-21. About 55.8 percent of program trading took place on the NYSE, 13.5 percent in non-U.S. markets and 30.7 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 56.5 percent during June 17-21. Program volume executed as principal, for their own accounts, amounted to 34.0 percent of program volume.

Another 9.5 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, Deutsche Banc Alex Brown executed most of its program trading activity for its customers, as agent. Morgan Stanley, UBS Warburg and Credit Suisse First Boston executed most of their program trading as principal, for their own accounts. Goldman Sachs split its activity between its own accounts and those of its customers.

During June 17-21, 13.9 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.

Another 0.1% 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 86.0 percent of member firms' program-trading volume during June 17-21.
