The SEC approved an options trading experiment.

The SEC gave permission for a one-year pilot program allowing options trading on six highly active over-the-counter stocks, beginning Oct. 1. The National Assn. of Securities Dealers will be allowed to trade in both options and their underlying stock. The experiment was approved on condition that the six stock exchanges be permitted the same right, even though the six stocks are not listed on those exchanges. The stocks were not specified in the decision.
