ADR is like an entry ticket for foreign stocks in the U.S. market, allowing you to buy and sell stocks of companies from China or other countries directly in USD on U.S. exchanges. You don’t need to open an overseas account or deal with complex foreign currency exchanges. When you check depositary receipt quotes, all information is displayed in USD, making it easier for you to compare and decide on your investments.
American Depositary Receipt (ADR) is a security issued by a U.S. bank. You can think of ADR as a “ticket” representing the stocks of a foreign company. When you purchase an ADR, you actually hold a security issued by a U.S. bank, not the foreign company’s stock directly. The U.S. bank first purchases the foreign company’s stocks, stores them in a custodian bank overseas, and then issues ADRs based on those stocks. You can buy and sell these securities in USD on U.S. exchanges without opening an overseas brokerage account or dealing with currency exchanges.
You can buy and sell ADR directly in USD on major U.S. exchanges like the New York Stock Exchange (NYSE) or NASDAQ, with a process as simple as trading U.S. domestic stocks.
The primary function of ADR is to allow you to invest in non-U.S. company stocks easily. You don’t need to handle complicated cross-border transfers or worry about currency settlements. You can buy and sell directly in the U.S. market with USD, enjoying the same trading convenience as U.S. stocks.
The liquidity and popularity of ADR are very high. Take TSMC ADR as an example:
You can see that ADR not only makes it convenient to invest in foreign companies but also offers high liquidity and market recognition. These features make ADR a vital tool for U.S. investors to participate in global markets.

You can imagine the birth of an ADR as a rigorous process. First, a bank in the U.S. or Hong Kong purchases the stocks of a designated company on a foreign stock market. These stocks are then held by a professional custodian bank (e.g., JP Morgan) to ensure safety and legality. Afterward, the bank issues a corresponding number of ADRs to investors like you based on the number of foreign stocks held.
Here’s a specific process example:
This process ensures that when you trade ADR in the U.S. market, there are real foreign stocks backing it, safeguarding your investment rights.
How many foreign stocks does each ADR represent? This ratio is called the “exchange ratio.” Different companies and banks set different ratios based on actual circumstances. For example:
You can refer to the table below for common ADR exchange ratios:
| Company Name | ADR Exchange Ratio | Exchange |
|---|---|---|
| ASLAN Pharmaceuticals | 29:1 | NASDAQ |
| TSMC (TSMC) | 5:1 | NYSE |
| Alibaba (Alibaba) | 1:8 | NYSE |
This ratio affects the number of foreign stocks you actually hold. For example, if you buy 100 ASLAN ADRs, you effectively hold 2,900 shares of ASLAN common stock. When trading ADRs, you must pay attention to the exchange ratio, as it impacts your investment scale and dividend distribution.
When you trade ADR in the U.S. market, all prices and dividends are calculated in USD. This allows you to trade directly in USD without currency exchange and without worrying about immediate exchange rate fluctuations affecting the trading process.
This USD pricing makes it more convenient for you to invest in foreign companies and manage your funds and profits. However, you still need to be mindful of exchange rate changes, as the foreign company’s dividends are initially calculated in local currency, converted to USD by the bank, and then paid to you.
You can directly check depositary receipt quotes on major U.S. exchanges, such as the New York Stock Exchange (NYSE) or NASDAQ. Depositary receipt quotes are displayed in USD, making them clear at a glance. You only need to enter the ADR ticker code on a brokerage platform to see real-time depositary receipt quotes. These quotes include the latest transaction price, bid-ask spread, volume, and other information. You can also look up depositary receipt quotes on financial websites or mobile apps. Depositary receipt quotes fluctuate based on market supply and demand, just like U.S. domestic stocks. Some ADRs are quoted on the OTC market (over-the-counter market), and these depositary receipt quotes are also calculated in USD. You can compare depositary receipt quotes across different platforms to choose the best time to buy or sell.
Tip: When checking depositary receipt quotes, remember to note the exchange ratio, as the number of foreign stocks represented by each ADR may differ.
The process of buying and selling ADR is almost the same as trading U.S. stocks. You only need to open a U.S. brokerage account, select the ADR you want to invest in, enter the quantity and price, and place the order. Depositary receipt quotes are reflected in real-time on your trading platform. After you place the order, the system matches the trade based on the depositary receipt quotes. You can choose a market order or a limit order to flexibly control your buying and selling timing. The dividends you receive will be paid in USD, making it easy to manage your funds. You don’t need to handle currency exchanges or overseas accounts, and the entire process is simple and straightforward. You can check depositary receipt quotes anytime to stay updated on market trends and make informed decisions.

When learning about ADR, you’ll often encounter another term—ADS. In fact, ADR (American Depositary Receipt) and ADS (American Depositary Share) are closely related but distinct concepts. You can understand them as follows:
When you trade in the U.S. market, you are actually buying and selling ADR. Each ADR corresponds to a certain number of ADS. For example, if you buy 1 TSMC ADR and its exchange ratio is 5:1, you effectively hold 5 shares of TSMC ADS.
Tip: When checking ADR quotes, remember to also note the number of ADS and the exchange ratio, as this will affect the number of foreign company shares you ultimately hold.
You can think of the relationship between ADR and ADS as similar to the relationship between a theater ticket and seats. ADR is like the ticket in your hand, giving you the right to enter the theater (U.S. market) to watch the performance of a foreign company (investment). ADS are the seats inside the theater, with each ticket (ADR) corresponding to one or more seats (ADS), depending on the theater’s rules (the exchange ratio set by the bank).
This metaphor can help you better understand the difference between ADR and ADS. When you trade in the U.S. market, you mainly focus on the price and quantity of ADR, but you actually hold ADS, which are the shares of the foreign company. Remember that the bank will calculate your final investment value and dividend distribution based on the number of ADS and the exchange rate (e.g., 1 USD = 7.8 HKD).
Investing in ADR offers several clear advantages, allowing you to easily participate in global markets:
Investing in ADR is not only convenient but also helps you diversify your portfolio, reducing the risk of relying on a single market.
Despite the multiple advantages of ADR, you still need to be aware of the following risks:
Tip: Before investing in ADR, carefully research the financial condition and market performance of the related company, and understand any fees that may be involved.
Exchange rate fluctuations are a factor you cannot ignore when investing in ADR. Although you trade in USD, the dividends paid by foreign companies are typically calculated in local currency. The bank will convert these dividends into USD and distribute them to you. If the local currency depreciates against the USD, the dividends you receive may decrease.
For example, if you hold TSMC ADR and TSMC pays dividends in New Taiwan Dollar (TWD), if the exchange rate changes from 1 USD = 30 TWD to 1 USD = 35 TWD, the USD dividends you receive will decrease.
Reminder: Exchange rate fluctuations not only affect dividends but may also impact ADR prices. When the local currency depreciates, the ADR price may decline, further affecting your investment returns.
If you want to participate in ADR trading, you first need to open a U.S. brokerage account. You can choose to open an account directly with a U.S. online broker (e.g., Interactive Brokers, Charles Schwab) or through the overseas securities services of a Hong Kong bank. The account opening process generally includes the following steps:
Tip: You can pre-establish a designated account with a Hong Kong bank to facilitate future regular transfers to the U.S. broker, reducing processing time.
After completing account opening and funding, you can start buying and selling ADR. The general operation process is as follows:
You can refer to the table below to compare the trading process and costs of TSMC Taiwan stocks and TSMC ADR:
| Item | TSMC Taiwan Stock (2330) Trading Process and Costs | TSMC ADR Trading Process and Costs |
|---|---|---|
| Buy Commission | Approx. 0.1425% of transaction amount, about 14 USD (at 1 USD = 30 TWD) | 0 commission |
| Sell Commission | Approx. 0.1425% of transaction amount, about 14 USD | 0 commission |
| Stock Transaction Tax | 0.3% payable on sale, about 60 USD | No stock transaction tax |
| Dividend Income Tax | Combined tax approx. 13 USD, separate tax approx. 104 USD | Withholding tax 21%, about 78 USD |
| Wire Transfer Fees | None | Outgoing and incoming fees approx. 33 USD each, totaling about 66 USD |
| Other Notes | Eligible for dividend distribution and voting rights | ADR exchange ratio 1:5, suitable for high-frequency traders |
You can see that trading ADR is not only simple, but some brokers also offer zero-commission benefits. However, wire transfer and tax costs need special attention. Popular ADRs include Alibaba (BABA), Tencent (TCEHY), and TSMC (TSM), which are familiar choices for Hong Kong investors.
American Depositary Receipts (ADR) provide you with a simple way to invest in companies from China or other countries in the U.S. market. Its convenience and USD pricing features allow you to participate in global markets without handling currency exchanges or overseas accounts.
However, when investing in ADR, you need to be aware of some key risks. For example, exchange rate fluctuations may affect your dividend income, and some foreign companies may have lower information transparency, increasing investment uncertainty.
Tip: Before deciding whether to invest in ADR, carefully assess your risk tolerance and investment goals. This will allow you to better utilize ADR to expand your portfolio and achieve financial growth.
ADR is suitable for investors who want to invest in foreign companies without dealing with currency exchanges or overseas accounts. If you seek a simple trading process and the convenience of USD pricing, ADR is an ideal choice. However, you need to consider risks related to exchange rate fluctuations and information transparency.
The bank will convert the dividends paid by the foreign company into USD and distribute them to you. The dividend amount depends on the original stock’s dividend and the ADR exchange ratio. For example, if the exchange ratio is 5:1, you can receive dividends for 5 shares per 1 ADR you hold.
You may need to pay bank management fees, such as dividend distribution fees or custody fees. Some brokers may offer zero-commission trading, but wire transfer fees to a U.S. brokerage account are typically around 33 USD.
The price of ADR is usually related to the price of the original stock but may differ due to exchange rate fluctuations or market supply and demand. For example, when the local currency depreciates, the ADR price may decline. Additionally, differences in trading hours can affect price synchronization.
You can enter the company name on a U.S. brokerage platform or financial website to look up the ADR ticker code. For example, TSMC’s ADR ticker is TSM. Quotes are displayed in USD, including the latest transaction price, bid-ask spread, and volume.
