A linkage between related information. Hypertext is the foundation of the World Wide Web, enabling users to click on a link to obtain more information on a subsequent page or from a Web site anywhere in the world. Hypertext is the umbrella term for all links, whether appearing as text (word, phrase or sentence) or as an icon or other graphical element, the latter technically called a "hypergraphic." The terms "hypertext," "hyperlink" and "link" are also used synonymously. See hypermedia, live link and virtual hypertext.

The term was coined by Ted Nelson in 1963. However, his vision was much more expansive than the one-way links of today's Web. Nelson proposed two-way linking and support for non-hierarchical organization (for more information, visit www.xanadu.com).

Linkage occurs when an investor is able to purchase a security on one financial exchange and sell it on another. Certain depositary receipts, such as American Depositary Receipts (ADRs), allow for linkage, which means that an investor can purchase shares of a company on a foreign exchange, such as the Toronto Stock Exchange, and then sell those shares on a domestic exchange, such as the New York Stock Exchange.

Investopedia Says:
Linkage should not be confused with arbitrage situations where an investor looks to profit from price discrepancies for equivalent securities trading on different exchanges. As financial markets progress, specifically with the growth of electronic exchanges spreading, the phenomenon of linkage will become more relevant and useful for investors in the future.
