Dual Listing A company's securities are listed on more than one exchange for the purpose of adding liquidity to the shares and allow investors greater choice in where they can trade their shares. Investopedia Says: Dual listing is not a widely used technique though it is thought to improve the spread between the bid and ask prices which helps investors obtain a better price for their security. Hewlett-Packard (HP), for example, is listed on both the NYSE and Nasdaq. Related Terms: Ask Bid Bid-Ask Spread Exchange Market Nasdaq New York Stock Exchange - NYSE |
