Usage
What does aftermarket mean? An aftermarket is a market for parts, accessories, or equipment used to maintain or improve an existing product, usually relating to machinery, especially automobiles. The aftermarket is a market for goods that can be used to repair, improve, or change a product that was already made on a primary, or standard, market. For example, when you buy a replacement power cable for your laptop from a company other than the computer manufacturer, you’re buying it on the aftermarket. Aftermarket is often paired with parts, as in The aftermarket parts for my car are actually of a better quality than the original parts. In the context of a stock exchange, aftermarket is used to mean a secondary market. The secondary market is the situation where investors buy and sell shares that are already owned. In contrast, the primary market is the situation where a company first sells its shares to investors. Before that, the company was owned privately. National markets like the New York Stock Exchange and the NASDAQ are aftermarkets. Example: Because her new car didn’t come with good-quality speakers, Libby searched the aftermarket for better speakers.
