A company that sells products involving sophisticated technology. Commonly, high-technology companies deal in electronics, computers and scientific research. Investing in high-technology companies is high risk because the market is stiffly competitive, but it may yield a high return, particularly if a technology suddenly becomes very popular. This was the case in the 1990s when the Internet became a part of daily life. Many high-technology stocks trade on NASDAQ. See also: Dot-com bubble.
