Term over-the-counter market Definition: A market that trades corporate stocks and other securities using a computerized network of dealers rather than an organized exchange. Over-the-counter market is most often used in reference to the National Association of Securities Dealers. Stocks traded over the counter tend to be smaller, less well-known, technology based firms. Start-up firms often begin offering their stock over the counter, then once established they move to organized exchanges, especially the New York Stock Exchange or the American Stock Exchange.
