General Automation Stock in New Trading System

General Automation Inc., an Anaheim producer of multi-user business computer systems, said that starting today, the company’s common stock will start trading on the National Market System of the National Assn. of Securities Dealers Automated Quotation.

The company’s stock, which had been traded on NASDAQ’s over-the-counter system, will continue to be traded under the symbol “GENA,” the company said Monday.

Under the new system, investors can buy stock on margin, which means they can use a broker’s credit as partial payment for stock. The company has 4.8 million common shares outstanding.
