New York Stock Exchange officials are considering whether to reorganize the world's largest security exchange by creating a holding company that would own as subsidiaries the stock exchange, the new futures exchange and any other trading floors that the Big Board might add.

Officially, the NYSE has no comment on Wall Street Journal report that a special committee of the NYSE board might recommend creation of a holding company. Former General Motors Chairman James Roche, chairman of the committee set up last spring, said the group is still "gathering facts" and that reports of any recommendations are "purely speculative."

But sources familiar with the committee said the group has studied the holding company concept as a way of more intelligently managing Big Board operations as it adds other trading markets to its long-standing securities exchange.

The futures exchange is expected to open about April 1 and will be a subsidiary of the nonprofit NYSE. The exchange, which rejected establishing an options trading floor in 1972, also hopes to add options trading if it gets approval of the Securities and Exchange Commission.

The holding company concept is hardly a new one to American business.

Many corporations are parent companies to a host of independent subsidiaries. If the NYSE became a holding company, members of the futures exchange likely would have a voice in overall exchange policy.

Sources said each trading subsidiary would have its own rules and that individuals or other equities buyers and sellers would see no difference in the way business is transacted if the Big Board should reorganize.
