dual listing investment & finance definition

The listing of a security on more than one exchange. Many stocks are traded on the New York or the American stock exchanges and on one or more of the regional exchanges. For example, the common stock of General Motors is listed on the New York Stock Exchange, but it also enjoys a large amount of activity on regional exchanges. Although dual listing theoretically should improve the liquidity of a stock thereby benefiting investors, most dual listed securities trade chiefly on one exchange.
