A dealer market (also known as an over-the-counter (OTC) market) is a financial marketplace where you don't trade with other investors directly. Instead, you buy from and sell to a dealer who acts as a middleman. Think of it less like an open auction and more like visiting a specialized shop. These dealers, often called market makers, maintain an inventory of securities and publicly post the prices at which they're willing to buy (the bid price) and sell (the ask price). They profit from the difference between these two prices, a gap known as the bid-ask spread. Unlike an auction market like the New York Stock Exchange (NYSE), there's no central trading floor or single order book. The “market” is a vast, decentralized electronic network connecting these dealers. While you might associate stock trading with frenzied auction floors, a huge portion of the financial world, including the entire bond market and the global currency market, operates this way.
Imagine you want to buy a rare comic book. You wouldn't go to a big auction house where everyone is shouting bids. Instead, you'd likely go to a specialty comic book shop. The shop owner (the dealer) has a stock of comics and a set price to sell one to you. If you wanted to sell your own rare comic, the owner would offer you a lower price to buy it from you. The dealer market works on the same principle.
The whole system is built on competition. If one dealer's spread is too wide (meaning their buy price is too low and their sell price is too high), your broker will simply take your business to another dealer with a better offer.
Understanding the difference between a dealer market and an auction market is key to knowing where your money is going. The most famous dealer market is Nasdaq, while the NYSE is the classic example of an auction market.
You might be surprised by how much of the investment world operates on the OTC/dealer model. It's the go-to structure for assets that aren't standardized or don't trade frequently enough for an auction model.
For a value investor, the unique characteristics of dealer markets present both opportunities and dangers that demand a sharp eye.
While you may spend most of your time with stocks on the NYSE or Nasdaq, understanding the dealer market is essential. It's the backbone of the bond and currency worlds and home to potential deep-value (and high-risk) stocks. Your best defense is knowledge. Before venturing into the OTC world, know the company inside and out, be acutely aware of the bid-ask spread, and understand that you may need to hold the asset for a long time.
