What Is the American Stock Exchange (AMEX)?

The American Stock Exchange (AMEX) was once the third-largest stock exchange in the United States, as measured by trading volume. The exchange, at its height, handled about 10% of all securities traded in the U.S.

Today, the AMEX is known as the NYSE American. In 2008, NYSE Euronext acquired the AMEX. In the subsequent years, it also became known as NYSE Amex Equities and NYSE MKT.

Understanding the American Stock Exchange (AMEX)

The AMEX developed a reputation over time as an exchange that introduced and traded new products and asset classes. For example, it launched its options market in 1975. Options are a type of derivative security. They are contracts that grant the holder the right to buy or sell an asset at a set price on or before a certain date, without the obligation to do so. When the AMEX launched its options market, it also distributed educational materials to help educate investors as to the potential benefits and risks.

In 1993, the AMEX introduced the first exchange traded fund (ETF). The ETF, now a popular investment, is a type of security that tracks an index or a basket of assets. They are much like mutual funds but differ in that they trade like stocks on an exchange.

Over time, the AMEX gained the reputation of listing companies that could not meet the strict requirements of the NYSE. Today, a good portion of trading on the NYSE American is in small cap stocks. It operates as a fully electronic exchange.

History of the American Stock Exchange (AMEX)

The AMEX dates back to the late 18th century when the American trading market was still developing. At that time, without a formalized exchange, stockbrokers would meet in coffeehouses and on the street to trade securities. For this reason, the AMEX became known at one time as the New York Curb Exchange.

The traders who originally met in the streets of New York became known as curbstone brokers. They specialized in trading stocks of emerging companies. At the time, many of these emerging businesses were in industries such as railroads, oil, and textiles, while those industries were still getting off the ground.

In the 19th century, this type of curbside trading was informal and quite disorganized. In 1908, the New York Curb Market Agency was established in order to bring rules and regulations to trading practices.

In 1929, the New York Curb Market became the New York Curb Exchange. It had a formalized trading floor and a set of rules and regulations. In the 1950s, more and more emerging businesses began trading their stocks on the New York Curb Exchange. The value of companies listed on the exchange almost doubled between 1950 and 1960, going from $12 billion to $23 billion during that time. The New York Curb Exchange changed its name to the American Stock Exchange in 1953.

Special Considerations

Over the years, the NYSE American has become an attractive listing place for younger, entrepreneurial companies, some of whom are in the early stages of their growth and certainly not as well-known as blue chip companies. Compared to the NYSE and Nasdaq, the NYSE American trades at much smaller volumes.

Because of these factors, there could be concerns that investors would not be able to quickly buy and sell some securities in the market. To ensure market liquidity—which is the ease at which a security can be converted to cash without impacting its market price—the NYSE American offers electronic designated market makers.

Market makers are individuals or firms that are available to buy and sell a particular security as needed throughout the trading session. These designated market makers have quoting obligations for specific NYSE American-listed companies. In return for making a market for a security, market makers earn money through the bid-ask spread and from fees and commissions. So, despite the fact that the NYSE American is a smaller-volume exchange specializing in listing smaller companies, its use of market makers enables it to maintain liquidity and an orderly market.

What Is an Account Balance?

An account balance is the amount of money present in a financial repository, such as a savings or checking account, at any given moment. The account balance is always the net amount after factoring in all debits and credits. An account balance that falls below zero represents a net debt—for example, when there is an overdraft on a checking account. For financial accounts that have recurring bills, such as an electric bill or a mortgage, an account balance may also reflect an amount owed.

Understanding an Account Balance

Your account balance shows your total assets minus total liabilities. Sometimes this can be referred to as your net worth or total wealth because it subtracts any debts or obligations from positive sums. For specific accounts at a financial institution, such as a checking account or a brokerage account, your account balance will reflect the current sum of funds or value of that account. For investments or other risky assets, your account balance will tend to change over time as security prices rise and fall in the market.

Many other financial accounts also have an account balance. Everything from a utility bill to a mortgage account needs to show you the balance of the account. For financial accounts that have recurring bills, such as a water bill, your account balance usually shows the amount owed. An account balance can also refer to the total amount of money you owe to a third party, such as a credit card company, utility company, mortgage banker, or another type of lender or creditor.

In banking, the account balance is the amount of money you have available in your checking or savings account. Your account balance is the net amount available to you after all deposits and credits have been balanced with any charges or debits. Sometimes your account balance does not reflect the most accurate representation of your available funds, due to pending transactions or checks that have not been processed.

Examples of Account Balances

In the case of a credit card, you may have made various purchases of $100, $50, and $25 and returned another item costing $10. The account balance includes the purchases made, which total $175, but also the item returned for $10. The net of the debits and credits is $165, or $175 minus $10, and that amount is your account balance.

In the case of a checking account, if your starting balance is $500, and you received a check for $1,500 and also wrote a check or scheduled an automatic payment for $750, then your account balance might show $2,000 immediately, depending on the banking establishment. However, the true account balance is $1,250. It is important to keep track of account balances by recording every credit and debit and then reconciling your calculated balance with the bank statement balance each month.

Account Balance vs. Available Credit

For credit cards, account balances are the total amount of debt owed at the start of the statement date. Your account balance on a credit card also includes any debt rolled over from previous months, which may have accrued interest charges. Available credit is the term used alongside the account balance to indicate how much of the credit line you have left to spend.

For some bank accounts, deposits may not clear in whole or in part immediately, taking up to a few business days to show up in your account. In such situations the bank will usually indicate to you the current available balance alongside the unavailable amount that is waiting to clear.
