What Is the Australian Securities Exchange (ASX)?

The Australian Securities Exchange is headquartered in Sydney, Australia. The Exchange in its current form was created through the merger of the Australian Stock Exchange and Sydney Futures Exchange in 2006. The ASX acts as a market operator, clearing house, and payments facilitator. It also provides educational materials to retail investors.

Understanding the Australian Securities Exchange (ASX)

ASX is consistently ranked among the top exchanges globally. Other major exchanges include the Tokyo Stock Exchange or TSE, the New York Stock Exchange (NYSE), the Nasdaq, and the London Stock Exchange (LSE). Each exchange has specific listing requirements that include regular financial reports and minimum capital requirements. For example, in 2021, the NYSE has a key listing requirement that stipulated aggregate shareholders equity for last three fiscal years of greater than or equal to $10 million, a global market capitalization of $200 million, and a minimum share price of $4. In addition, for initial public offerings and secondary issuers must have 400 shareholders.

Australian Securities Exchange (ASX) and Electronic Trading

As with the majority of international exchanges, ASX’s relies on a hefty data center to help connect it to leading financial hubs and facilitate electronic trading. Electronic trading gained strong traction with NYSE’s 2005 acquisition of rival market the Archipelago Exchange—a fully electronic exchange that listed new and fast-growing companies. NYSE Arca was the new name following the acquisition. Cybersecurity is an increasing concern as exchanges become more interconnected via the internet.

ASX and Education

The Australian Securities Exchange has a strong emphasis on educating visitors to its website, the investing public, and current and potential listers. For example, for first-time investors, ASX offers free resources for understanding the public markets, exploring different asset classes, and developing a personal investment strategy. Visitors can download a series of tutorials and guidebooks. In addition, ASX offers a game-version of trading where players do not have to risk real money; instead, they can learn the basics in a risk-free environment.

What Is Arbitrage?

Arbitrage is the simultaneous purchase and sale of the same or similar asset in different markets in order to profit from tiny differences in the asset’s listed price. It exploits short-lived variations in the price of identical or similar financial instruments in different markets or in different forms.

Arbitrage exists as a result of market inefficiencies, and it both exploits those inefficiencies and resolves them.

Understanding Arbitrage

Arbitrage can be used whenever any stock, commodity, or currency may be purchased in one market at a given price and simultaneously sold in another market at a higher price. The situation creates an opportunity for a risk-free profit for the trader.

Arbitrage provides a mechanism to ensure that prices do not deviate substantially from fair value for long periods of time. With advancements in technology, it has become extremely difficult to profit from pricing errors in the market. Many traders have computerized trading systems set to monitor fluctuations in similar financial instruments. Any inefficient pricing setups are usually acted upon quickly, and the opportunity is eliminated, often in a matter of seconds.

Examples of Arbitrage

As a straightforward example of arbitrage, consider the following: The stock of Company X is trading at $20 on the New York Stock Exchange (NYSE), while, at the same moment, it is trading for $20.05 on the London Stock Exchange (LSE).

A trader can buy the stock on the NYSE and immediately sell the same shares on the LSE, earning a profit of 5 cents per share.

The trader can continue to exploit this arbitrage until the specialists on the NYSE run out of inventory of Company X’s stock, or until the specialists on the NYSE or the LSE adjust their prices to wipe out the opportunity.

A More Complicated Arbitrage Example

A trickier example can be found in currencies markets using triangular arbitrage. In this case, the trader converts one currency to another, converts that second currency to a third bank, and finally converts the third currency back to the original currency.

Suppose you have $1 million and you are provided with the following exchange rates: USD/EUR = 1.1586, EUR/GBP = 1.4600, and USD/GBP = 1.6939.

With these exchange rates, there is an arbitrage opportunity:

1. Sell dollars to buy euros: $1 million ÷ 1.1586 = €863,110
2. Sell euros for pounds: €863,100 ÷ 1.4600 = £591,171
3. Sell pounds for dollars: £591,171 × 1.6939 = $1,001,384
4. Subtract the initial investment from the final amount: $1,001,384 – $1,000,000 = $1,384

From these transactions, you would receive an arbitrage profit of $1,384 (assuming no transaction costs or taxes).

The Bottom Line

Arbitrage is a condition where you can simultaneously buy and sell the same or similar product or asset at different prices, resulting in a risk-free profit.

Economic theory states that arbitrage should not be able to occur because if markets are efficient, there would be no such opportunities to profit. However, in reality, markets can be inefficient and arbitrage can happen. When arbitrageurs identify and then correct such mispricings (by buying them low and selling them high), though, they work to move prices back in line with market efficiency. This means that any arbitrage opportunities that do occur are short-lived.

There are many different arbitrage strategies that exist, some involving complex interrelationships between different assets or securities.

What Is an Auction Market?

In an auction market, buyers enter competitive bids and sellers submit competitive offers at the same time. The price at which a stock trades represents the highest price that a buyer is willing to pay and the lowest price that a seller is willing to accept. Matching bids and offers are then paired together, and the orders are executed. The New York Stock Exchange (NYSE) is an example of an auction market.

Auction Market Process

The process involved in an auction market differs from the process in an over-the-counter (OTC) market. On the NYSE, for example, there are no direct negotiations between individual buyers and sellers, while negotiations occur in OTC trades. Most traditional auctions involve multiple potential buyers or bidders, but only a single seller, whereas auction markets for securities have multiple buyers and multiple sellers, all looking to make deals simultaneously.

Double Auction Markets

An auction market also known as a double auction market, allows buyers and sellers to submit prices they deem acceptable to a list. When a match between a buyer’s price and a seller’s asking price is found, the trade proceeds at that price. Trades without matches will not be executed.

Examples of the Auction Market Process

Imagine that four buyers want to buy a share of company XYZ and make the following bids: $10.00, $10.02, $10.03 and $10.06, respectively. Conversely, four sellers wish to sell shares of company XYZ, and these sellers submitted offers to sell their shares at the following prices: $10.06, $10.09, $10.12 and $10.13, respectively.

In this scenario, the individuals that made bids/offers for company XYZ at $10.06 will have their orders executed. All remaining orders will not immediately be executed, and the current price of company XYZ will be $10.06.

Treasury Auctions

The U.S. Treasury holds auctions to finance certain government financial activities. The Treasury auction is open to the public and various larger investment entities. These bids are submitted electronically and are divided into competing and noncompeting bids depending on the person or entity who places the recorded bid.

Noncompeting bids are addressed first because noncompetitive bidders are guaranteed to receive a predetermined amount of securities as a minimum and up to a maximum of $5 million. These are most commonly entered by individual investors or those representing small entities.

In competitive bidding, once the auction period closes, all of the incoming bids are reviewed to determine the winning price. Securities are sold to the competing bidders based on the amount listed within the bid. Once all of the securities have been sold, the remaining competing bidders will not receive any securities.

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.
