What Was the American Stock Exchange (AMEX)?

Let me tell you about the American Stock Exchange, or AMEX as it's commonly known. It used to be the third-largest stock exchange in the United States based on trading volume. At its peak, it managed around 10% of all securities traded in the U.S.

These days, you'll find it operating under the name NYSE American. Back in 2008, NYSE Euronext bought it out, and over the years, it went through names like NYSE Amex Equities and NYSE MKT.

Key Takeaways on AMEX

The American Stock Exchange started out as the New York Curb Exchange and played a big role in bringing new financial products to the market, such as options and ETFs. After its acquisition by NYSE Euronext in 2008, it's now NYSE American, which mainly deals with small-cap stocks on a fully electronic trading system.

Its history ties directly into the growth of American financial markets, beginning with informal trading on the streets in the late 18th century. NYSE American stands out by offering a venue for younger, entrepreneurial companies that don't qualify for the tougher standards of bigger exchanges like the NYSE.

Even with its emphasis on smaller-cap stocks and lower trading volumes, NYSE American uses designated market makers to keep things liquid and stable.

Exploring the Role and Innovations of the AMEX

Over time, the AMEX built a solid reputation for introducing and trading new products and asset classes. Take options, for instance—it launched its options market in 1975. Options are derivative securities, basically contracts that give you the right, but not the obligation, to buy or sell an asset at a fixed price by a certain date. When AMEX started this, they even provided educational materials to explain the benefits and risks to investors.

You should know that AMEX was once a strong rival to the New York Stock Exchange (NYSE), but eventually, Nasdaq took over that competitive spot. In 1993, AMEX brought out the first exchange-traded fund (ETF), which has become a go-to investment. ETFs track an index or a group of assets, similar to mutual funds, but they trade like stocks on an exchange.

AMEX got known for listing companies that couldn't meet the NYSE's stricter rules. Today, much of the trading on NYSE American involves small-cap stocks, and it runs entirely electronically.

The Evolution of the American Stock Exchange (AMEX)

AMEX traces its roots back to the late 18th century as the American trading market was developing. Without a proper exchange, stockbrokers did their business in coffeehouses and right on the streets, which is why it was once called the New York Curb Exchange.

Those early traders, known as curbstone brokers, focused on stocks from emerging companies in growing industries like railroads, oil, and textiles. In the 19th century, this curbside trading was pretty informal and chaotic. Then, in 1908, the New York Curb Market Agency stepped in to set some rules and regulations.

By 1929, it became the New York Curb Exchange with a formal trading floor and established guidelines. In the 1950s, more emerging businesses started listing there, and the value of listed companies nearly doubled from $12 billion to $23 billion between 1950 and 1960. The name changed to the American Stock Exchange in 1953.

Key Factors and Advantages of Listing on NYSE American

Through the years, NYSE American has become a go-to spot for younger, entrepreneurial companies in their early growth stages, often not as established as blue-chip firms. It handles much smaller trading volumes compared to the NYSE or Nasdaq.

This setup might worry you about how quickly you can trade certain securities. To handle liquidity—the ability to convert a security to cash without affecting its price—NYSE American uses electronic designated market makers.

These market makers are individuals or firms ready to buy and sell specific securities during trading hours. They have obligations to quote prices for NYSE American-listed companies, and in exchange, they profit from the bid-ask spread plus fees and commissions. So, even as a smaller exchange focused on lesser-known companies, NYSE American keeps the market liquid and orderly through these makers.
