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 Are Assets Under Management (AUM)?

Assets under management (AUM) is the total market value of the investments that a person or entity manages on behalf of clients. Assets under management definitions and formulas vary by company.

In the calculation of AUM, some financial institutions include bank deposits, mutual funds, and cash in their calculations. Others limit it to funds under discretionary management, where the investor assigns authority to the company to trade on their behalf.

Overall, AUM is only one aspect used in evaluating a company or investment. It is also usually considered in conjunction with management performance and management experience. However, investors often consider higher investment inflows and higher AUM comparisons as a positive indicator of quality and management experience.

Understanding Assets Under Management

Assets under management refers to how much money a hedge fund or financial institution is managing for their clients. AUM is the sum of the market value for all of the investments managed by a fund or family of funds, a venture capital firm, brokerage company, or an individual registered as an investment advisor or portfolio manager.

Used to indicate the size or amount, AUM can be segregated in many ways. It can refer to the total amount of assets managed for all clients, or it can refer to the total assets managed for a specific client. AUM includes the capital the manager can use to make transactions for one or all clients, usually on a discretionary basis.

For example, if an investor has $50,000 invested in a mutual fund, those funds become part of the total AUM—the pool of funds. The fund manager can buy and sell shares following the fund’s investment objective using all of the invested funds without obtaining any additional special permissions.

Within the wealth management industry, some investment managers may have requirements based on AUM. In other words, an investor may need a minimum amount of personal AUM for that investor to be qualified for a certain type of investment, such as a hedge fund. Wealth managers want to ensure the client can withstand adverse markets without taking too large of a financial hit. An investor’s individual AUM can also be a factor in determining the type of services received from a financial advisor or brokerage company. In some cases, individual assets under management may also coincide with an individual’s net worth.

Calculating Assets Under Management

Methods of calculating assets under management vary among companies. Assets under management depends on the flow of investor money in and out of a particular fund and as a result, can fluctuate daily. Also, asset performance, capital appreciation, and reinvested dividends will all increase the AUM of a fund. Also, total firm assets under management can increase when new customers and their assets are acquired.

Factors causing decreases in AUM include decreases in market value from investment performance losses, fund closures, and a decrease in investor flows. Assets under management can be limited to all of the investor capital invested across all of the firm’s products, or it can include capital owned by the investment company executives.

In the United States, the Securities and Exchange Commission (SEC) has AUM requirements for funds and investment firms in which they must register with the SEC. The SEC is responsible for regulating the financial markets to ensure that it functions in a fair and orderly manner. The SEC requirement for registration can range between $25 million to $110 million in AUM, depending on several factors, including the size and location of the firm.

Why AUM Matters

Firm management will monitor AUM as it relates to investment strategy and investor product flows in determining the strength of the company. Investment companies also use assets under management as a marketing tool to attract new investors. AUM can help investors get an indication of the size of a company’s operations relative to its competitors.

AUM may also be an important consideration for the calculation of fees. Many investment products charge management fees that are a fixed percentage of assets under management. Also, many financial advisors and personal money managers charge clients a percentage of their total assets under management. Typically, this percentage decreases as the AUM increases; in this way, these financial professionals can attract high-wealth investors.

Real-Life Examples of Assets Under Management

When evaluating a specific fund, investors often look at its AUM since it functions as an indication of the size of the fund. Typically, investment products with high AUMs have higher market trading volumes making them more liquid, meaning investors can buy and sell the fund with ease.

SPY

For example, the SPDR S&P 500 ETF (SPY) is one of the largest equity exchange-traded funds on the market. An ETF is a fund that contains a number of stocks or securities that match or mirror an index, such as the S&P 500. The SPY has all 500 of the stocks in the S&P 500 index.

As of Mar. 11, 2022, the SPY had assets under management of $380.7 billion with an average daily trading volume of 113 million shares. The high trading volume means liquidity is not a factor for investors when seeking to buy or sell their shares of the ETF.

EDOW

The First Trust Dow 30 Equal Weight ETF (EDOW) tracks the 30 stocks in the Dow Jones Industrial Average (DJIA). As of Mar. 11, 2022, the EDOW had assets under management of $130 million and much lower trading volume compared to the SPY, averaging approximately 53,000 shares per day. Liquidity for this fund could be a consideration for investors, meaning it could be difficult to buy and sell shares at certain times of the day or week.

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 an Auditor’s Report?

An auditor’s report is a written letter from the auditor containing their opinion on whether a company’s financial statements comply with generally accepted accounting principles (GAAP) and are free from material misstatement.

The independent and external audit report is typically published with the company’s annual report. The auditor’s report is important because banks and creditors require an audit of a company’s financial statements before lending to them.

How an Auditor’s Report Works

An auditor’s report is a written letter attached to a company’s financial statements that expresses its opinion on a company’s compliance with standard accounting practices. The auditor’s report is required to be filed with a public company’s financial statements when reporting earnings to the Securities and Exchange Commission (SEC).

However, an auditor’s report is not an evaluation of whether a company is a good investment. Also, the audit report is not an analysis of the company’s earnings performance for the period. Instead, the report is merely a measure of the reliability of the financial statements.

The Components of an Auditor’s Report

The auditor’s letter follows a standard format, as established by generally accepted auditing standards (GAAS). A report usually consists of three paragraphs.

• The first paragraph states the responsibilities of the auditor and directors.
• The second paragraph contains the scope, stating that a set of standard accounting practices was the guide.
• The third paragraph contains the auditor’s opinion.

An additional paragraph may inform the investor of the results of a separate audit on another function of the entity. The investor will key in on the third paragraph, where the opinion is stated.

The type of report issued will be dependent on the findings by the auditor. Below are the most common types of reports issued for companies.

Clean or Unqualified Report

A clean report means that the company’s financial records are free from material misstatement and conform to the guidelines set by GAAP. A majority of audits end in unqualified, or clean, opinions.

Qualified Opinion

A qualified opinion may be issued in one of two situations: first, if the financial statements contain material misstatements that are not pervasive; or second, if the auditor is unable to obtain sufficient appropriate audit evidence on which to base an opinion, but the possible effects of any material misstatements are not pervasive. For example, a mistake might have been made in calculating operating expenses or profit. Auditors typically state the specific reasons and areas where the issues are present so that the company can fix them.

Adverse Opinion

An adverse opinion means that the auditor has obtained sufficient audit evidence and concludes that misstatements in the financial statements are both material and pervasive. An adverse opinion is the worst possible outcome for a company and can have a lasting impact and legal ramifications if not corrected.

Disclaimer of Opinion

A disclaimer of opinion means that, for some reason, the auditor is unable to obtain sufficient audit evidence on which to base the opinion, and the possible effects on the financial statements of undetected misstatements, if any, could be both material and pervasive. Examples can include when an auditor can’t be impartial or wasn’t allowed access to certain financial information.

Example of an Auditor’s Report

Excerpts from the audit report by Deloitte & Touche LLP for Starbucks Corporation, dated Nov. 15, 2019, follow.

Paragraph 1: Opinion on the Financial Statements

“We have audited the accompanying consolidated balance sheets of Starbucks Corporation and subsidiaries (the ‘Company’) as of September 29, 2019, and September 30, 2018, the related consolidated statements of earnings, comprehensive income, equity, and cash flows, for each of the three years in the period ended September 29, 2019, and the related notes (collectively referred to as the ‘financial statements’).

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of September 29, 2019, and September 30, 2018, and the results of its operations and its cash flows for each of the three years in the period ended September 29, 2019, in conformity with accounting principles generally accepted in the United States of America.”

Paragraph 2: Basis for Opinion

“We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (PCAOB). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks.

Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.”
