What Is the Advance/Decline (A/D) Line?

The advance/decline line (or A/D line) is a technical indicator that plots the difference between the number of advancing and declining stocks on a daily basis. The indicator is cumulative, with a positive number being added to the prior number, or if the number is negative it is subtracted from the prior number.

The A/D line is used to show market sentiment, as it tells traders whether there are more stocks rising or falling. It is used to confirm price trends in major indexes, and can also warn of reversals when divergence occurs.

The Formula for Advance/Decline (A/D) Line Is:


$\begin{aligned} &\text{A/D} = \text{Net Advances} + \begin{cases} \text{PA, if PA value exists} \\ \text{0, if no PA value} \\ \end{cases} \\ &\textbf{where:} \\ &\text{Net Advances} = \text{Difference between number of daily} \\ &\text{ascending and declining stocks} \\ &\text{PA} = \text{Previous Advances} \\ &\text{Previous Advances} = \text{Prior indicator reading} \\ \end{aligned}$​A/D=Net Advances+{PA, if PA value exists0, if no PA value​where:Net Advances=Difference between number of dailyascending and declining stocksPA=Previous AdvancesPrevious Advances=Prior indicator reading​

How to Calculate the A/D Line

1. Subtract the number of stocks that finished lower on the day from the number of stocks that finished higher on the day. This will give you the Net Advances.
2. If this is the first time calculating the average, the Net Advances will be the first value used for the indicator.
3. On the next day, calculate the Net Advances for that day. Add to the total from the prior day if positive or subtract if negative.
4. Repeat steps one and three daily.

What Does the A/D Line Tell You?

The A/D line is used to confirm the strength of a current trend and its likelihood of reversing. The indicator shows if the majority of stocks are participating in the direction of the market. 

If the indexes are moving up but the A/D line is sloping downwards, called bearish divergence, it’s a sign that the markets are losing their breadth and may be about to reverse direction. If the slope of the A/D line is up and the market is trending upward, then the market is said to be healthy.

Conversely, if the indexes are continuing to move lower and the A/D line has turned upwards, called bullish divergence, it may be an indication that the sellers are losing their conviction. If the A/D line and the markets are both trending lower together, there is a greater chance that declining prices will continue.

Difference Between the A/D Line and Arms Index (TRIN)

The A/D line is typically used as a longer-term indicator, showing how many stocks are rising and falling over time. The Arms Index (TRIN), on the other hand, is typically a shorter-term indicator that measures the ratio of advancing stocks to the ratio of advancing volume. Because the calculations and the time frame they focus on are different, both these indicators tell traders different pieces of information.

Limitations of Using the A/D Line

The A/D line won’t always provide accurate readings in regards to NASDAQ stocks. This is because the NASDAQ frequently lists small speculative companies, many of which eventually fail or get delisted. While the stocks get delisted on the exchange, they remain in the prior calculated values of the A/D line. This then affects future calculations which are added to the cumulative prior value. Because of this, the A/D line will sometimes fall for extended periods of time, even while NASDAQ-related indexes are rising.

Another thing to be aware of is that some indexes are market capitalization weighted. This means that the bigger the company the more impact they have on the index’s movement. The A/D line gives equal weight to all stocks. Therefore, it is a better gauge of the average small to mid-cap stock, and not the fewer in number large or mega-cap stocks.

What Is an American Depositary Receipt (ADR)?

The term American depositary receipt (ADR) refers to a negotiable certificate issued by a U.S. depositary bank representing a specified number of shares—usually one share—of a foreign company’s stock. The ADR trades on U.S. stock markets as any domestic shares would.

ADRs offer U.S. investors a way to purchase stock in overseas companies that would not otherwise be available. Foreign firms also benefit, as ADRs enable them to attract American investors and capital without the hassle and expense of listing on U.S. stock exchanges.

How American Depositary Receipts (ADRs) Work

American depositary receipts are denominated in U.S. dollars. The underlying security is held by a U.S. financial institution, often by an overseas branch. These securities are priced and traded in dollars and cleared through U.S. settlement systems.

In order to begin offering ADRs, a U.S. bank must purchase shares on a foreign exchange. The bank holds the stock as inventory and issues an ADR for domestic trading. ADRs list on either the New York Stock Exchange (NYSE) or the Nasdaq, but they are also sold over-the-counter (OTC).

U.S. banks require that foreign companies provide them with detailed financial information. This requirement makes it easier for American investors to assess a company’s financial health.

Types of American Depositary Receipts

American depositary receipts come in two basic categories:

Sponsored ADRs

A bank issues a sponsored ADR on behalf of the foreign company. The bank and the business enter into a legal arrangement. The foreign company usually pays the costs of issuing an ADR and retains control over it, while the bank handles the transactions with investors. Sponsored ADRs are categorized by what degree the foreign company complies with Securities and Exchange Commission (SEC) regulations and American accounting procedures.

Unsponsored ADRs

A bank also issues an unsponsored ADR. However, this certificate has no direct involvement, participation, or even permission from the foreign company. Theoretically, there could be several unsponsored ADRs for the same foreign company, issued by different U.S. banks. These different offerings may also offer varying dividends. With sponsored programs, there is only one ADR, issued by the bank working with the foreign company.

One primary difference between the two types of ADRs is where they trade. All except the lowest level of sponsored ADRs register with the SEC and trade on major U.S. stock exchanges. Unsponsored ADRs will trade only over the counter. Unsponsored ADRs never include voting rights.

ADR Levels

ADRs are additionally categorized into three levels, depending on the extent to which the foreign company has accessed the U.S. markets.

Level I

This is the most basic type of ADR where foreign companies either don’t qualify or don’t want to have their ADR listed on an exchange. This type of ADR can be used to establish a trading presence but not to raise capital.

Level I ADRs found only on the over-the-counter market have the loosest requirements from the Securities and Exchange Commission (SEC) and they are typically highly speculative. While they are riskier for investors than other types of ADRs, they are an easy and inexpensive way for a foreign company to gauge the level of U.S. investor interest in its securities.

Level II

As with Level I ADRs, Level II ADRs can be used to establish a trading presence on a stock exchange, and they can’t be used to raise capital. Level II ADRs have slightly more requirements from the SEC than do Level I ADRs, but they get higher visibility and trading volume. 

Level III

Level III ADRs are the most prestigious. With these, an issuer floats a public offering of ADRs on a U.S. exchange. They can be used to establish a substantial trading presence in the U.S. financial markets and raise capital for the foreign issuer. Issuers are subject to full reporting with the SEC.

American Depositary Receipt Pricing and Costs

An ADR may represent the underlying shares on a one-for-one basis, a fraction of a share, or multiple shares of the underlying company. The depositary bank will set the ratio of U.S. ADRs per home-country share at a value that they feel will appeal to investors. If an ADR’s value is too high, it may deter some investors. Conversely, if it is too low, investors may think the underlying securities resemble riskier penny stocks.

Because of arbitrage, an ADR’s price closely tracks that of the company’s stock on its home exchange. Remember that arbitrage is buying and selling the same asset at the same time in different markets. This allows traders to profit from any differences in the asset’s listed price. 

ADR Fees

Investing in an ADR may incur additional fees that are not charged for domestic stocks. The depositary bank that holds the underlying stock may charge a fee, known as a custody fee, to cover the cost of creating and issuing an ADR.

This fee will be outlined in the ADR prospectus, and typically ranges from one to three cents per share. The fee will be either deducted from dividends, or passed on to the investor’s brokerage firm.

ADRs and Taxes

Holders of ADRs realize any dividends and capital gains in U.S. dollars. However, dividend payments are net of currency conversion expenses and foreign taxes. Usually, the bank automatically withholds the necessary amount to cover expenses and foreign taxes.

Since this is the practice, American investors would need to seek a credit from the IRS or a refund from the foreign government’s taxing authority to avoid double taxation on any capital gains realized.

Advantages and Disadvantages of American Depositary Receipts

As with any investment, there are distinct advantages and disadvantages of investing in ADRs. We’ve listed some of the main ones below.

Advantages

As noted above, ADRs are just like stocks. This means they trade on a stock exchange or over the counter, making them fairly easy to access and trade. Investors can also easily track their performance by reviewing market data.

Purchasing ADRs is easy because they’re available directly through American brokers. This eliminates the need to go through foreign channels to buy stock in a company in which you may be interested. Since they’re available domestically, shares are denominated in U.S. dollars. But that doesn’t mean you avoid any direct risks associated with fluctuations in currency rates.

One of the most obvious benefits of investing in ADRs is that they provide investors with a way to diversify their portfolios. Investing in international securities allows you to open your investment portfolio up to greater rewards (along with the risks).

Disadvantages

The main problems associated with ADRs are that they may involve double taxation—locally and abroad—and how many companies are listed. Unlike domestic companies, there are a limited number of foreign entities whose ADRs are listed for the public to trade.

As noted above, some ADRs may not comply with SEC regulations. These are called unsponsored ADRs, which have no direct involvement by the company. In fact, some companies may not even provide permission to list their shares this way.

Although investors can avoid any of the direct risks that come with currency exchange, they may incur currency conversion fees when they invest in ADRs. These fees are established in order to directly link the foreign security and the one traded on the domestic market.

History of American Depositary Receipts

Before American depositary receipts were introduced in the 1920s, American investors who wanted shares of a non-U.S. listed company could only do so on international exchanges—an unrealistic option for the average person back then.

While easier in the contemporary digital age, there are still drawbacks to purchasing shares on international exchanges. One particularly daunting roadblock is currency exchange issues. Another important drawback is the regulatory differences between U.S. and foreign exchanges.

Before investing in an internationally traded company, U.S. investors have to familiarize themselves with the different financial authority’s regulations, or they could risk misunderstanding important information, such as the company’s financials. They might also need to set up a foreign account, as not all domestic brokers can trade internationally.

ADRs were developed because of the complexities involved in buying shares in foreign countries and the difficulties associated with trading at different prices and currency values. J.P. Morgan’s (JPM) predecessor firm Guaranty Trust pioneered the ADR concept. In 1927, it created and launched the first ADR, enabling U.S. investors to buy shares of famous British retailer Selfridges and helping the luxury depart store tap into global markets. The ADR was listed on the New York Curb Exchange.

A few years later, in 1931, the bank introduced the first sponsored ADR for British music company Electrical & Musical Industries (also known as EMI), the eventual home of the Beatles. Today, J.P. Morgan and BNY Mellon, another U.S. bank, continue to be actively involved in the ADR markets.

Real-World Example of ADRs

Between 1988 and 2018, German car manufacturer Volkswagen AG traded OTC in the U.S. as a sponsored ADR under the ticker VLKAY. In August 2018, Volkswagen terminated its ADR program. The next day, J.P. Morgan established an unsponsored ADR for Volkswagen, now trading under the ticker VWAGY.

Investors who held the old VLKAY ADRs had the option of cashing out, exchanging the ADRs for actual shares of Volkswagen stock—trading on German exchanges—or exchanging them for the new VWAGY ADRs.

The Bottom Line

American Depositary Receipts, or ADRs, allow Americans to invest in foreign companies. Although these companies do not ordinarily trade on the U.S. stock market, an ADR allows an investor to buy these stocks as easily as they would invest in any domestic stock. The arrangement also benefits foreign firms, allowing them to raise capital from the U.S. market.

Correction—Jan. 24, 2023: A previous version of this article wrongly stated that foreign currency exchange rate fluctuations do not affect the price of ADR and therefore ADR holders avoid any direct risks associated with fluctuations in currency rates. Actually, ADR have exchange rate risk and the price of an ADR is affected by the movements of both the company’s local share price and the national currency rate of exchange against the U.S. dollar.

What Is an Acquisition Premium?

An acquisition premium is a figure that’s the difference between the estimated real value of a company and the actual price paid to acquire it. An acquisition premium represents the increased cost of buying a target company during a merger and acquisition (M&A) transaction.

There is no requirement that a company pay a premium for acquiring another company; in fact, depending on the situation, it may even get a discount.

Understanding Acquisition Premiums

In an M&A scenario, the company that pays to acquire another company is known as the acquirer, and the company to be purchased or acquired is referred to as the target firm.

Reasons For Paying An Acquisition Premium

Typically, an acquiring company will pay an acquisition premium to close a deal and ward off competition. An acquisition premium might be paid, too, if the acquirer believes that the synergy created from the acquisition will be greater than the total cost of acquiring the target company. The size of the premium often depends on various factors such as competition within the industry, the presence of other bidders, and the motivations of the buyer and seller.

How Does An Acquisition Premium Work?

When a company decides that it wants to acquire another firm, it will first attempt to estimate the real value of the target company. For example, the enterprise value of Macy’s, using data from its 2017 10-K report, is estimated at $11.81 billion. After the acquiring company determines the real value of its target, it decides how much it is willing to pay on top of the real value so as to present an attractive deal to the target firm, especially if there are other firms that are considering an acquisition.

In the example above an acquirer may decide to pay a 20% premium to buy Macy’s. Thus, the total cost it will propose would be $11.81 billion x 1.2 = $14.17 billion. If this premium offer is accepted, then the acquisition premium value will be $14.17 billion – $11.81 billion = $2.36 billion, or in percentage form, 20%.

Arriving at the Acquisition Premium

You also may use a target company’s share price to arrive at the acquisition premium. For instance, if Macy’s is currently trading at $26 per share, and an acquirer is willing to pay $33 per share for the target company’s outstanding shares, then you may calculate the acquisition premium as ($33 – $26)/$26 = 27%.

Using our price-per-share example, let’s assume that there was no premium offer on the table and the agreed-upon acquisition cost was $26 per share. If the value of the company drops to $16 before the acquisition becomes final, the acquirer will find itself paying a premium of ($26 – $16)/$16 = 62.5%.

Acquisition Premiums in Financial Accounting

In financial accounting, the acquisition premium is known as goodwill—the portion of the purchase price that is higher than the sum of the net fair value of all of the assets purchased in the acquisition and the liabilities assumed in the process. The acquiring company records goodwill as a separate account on its balance sheet.

Goodwill factors in intangible assets like the value of a target company’s brand, solid customer base, good customer relations, healthy employee relations, and any patents or proprietary technology acquired from the target company. An adverse event, such as declining cash flows, economic depression, increased competitive environment and the like can lead to an impairment of goodwill, which occurs when the market value of the target company’s intangible assets drops below its acquisition cost. Any impairment results in a decrease in goodwill on the balance sheet and shows as a loss on the income statement.

An acquirer can purchase a target company for a discount, that is, for less than its fair value. When this occurs, negative goodwill is recognized.
