OSAKA — An Osaka Securities Exchange delegation left for the United States on Monday for talks with managers of the Nasdaq stock index to enhance business tieups and offer more financial products to Japanese investors, OSE officials said.

The delegation, led by OSE President Goro Tatsumi, will exchange proposals with the top managers of the U.S. National Association of Securities Dealers, the parent of the U.S. tech-laden Nasdaq over-the-counter stock market, during a one-week stay, the officials said.

The delegates will travel to New York, Chicago and other U.S. destinations, they added.

The OSE launched the Nasdaq Japan market, the Japanese version of the U.S. Nasdaq, on June 19 by teaming up with the NASD and Internet investor Masayoshi Son’s Softbank Corp.

The NASD and Softbank own Nasdaq Japan 50-50, and the OSE is accommodating the new bourse on its premises.

The OSE wants to arrange for leading companies whose shares trade on U.S. and European bourses to list on Nasdaq Japan, they said.

The Osaka bourse also wants to offer a greater variety of derivatives and financial products in collaboration with the U.S. Nasdaq, they said.

The U.S. Nasdaq appears ready to agree to upcoming OSE proposals to boost ties on derivatives trading, as it wants to prevent investors from shifting from the OTC market to external computerized trading systems, industry sources said.
