NYX Nyse Euronext

Program trading grew last week on the New York Stock Exchange, according to the subsidiary of NYSE Euronext (NYX), although total volume declined slightly.

The daily program-trading volume average was 635.8 million, or 28.4% of the average total of 2.24 billion shares changing hands. Those figures were up from 623.3 million, or 27.4% of the 2.28 billion average volume posted a week earlier.

The most active NYSE member for program trading was Goldman Sachs Group Inc. (GS). It was followed by Morgan Stanley (MS), Deutsche Bank AG (DB, DBK.XE) and Barclays PLC (BCS, BARC.LN).

Program trading encompasses a wide range of portfolio-trading strategies involving the purchase or sale of a basket of at least 15 stocks.
