Why Should You Understand ADR? Three Essential Reasons for Investors

For traders looking to invest internationally, ADR is the key to opening the door to overseas markets. Many investors feel unfamiliar and curious about ADRs, mainly because they offer a completely new way to invest. Rather than saying ADRs are difficult to understand, it’s better to see them as a bridge connecting global capital markets.

First, ADRs make international investing simple. Compared to directly purchasing foreign stocks, which requires opening local accounts, currency exchange, and adapting to different trading rules, with ADRs you only need to trade as if you were buying regular US stocks. Second, ADRs provide investment options far beyond the US stock market itself—you can invest in high-quality companies in China, Taiwan, Japan, and more on the same platform. Third, the reference value of ADRs lies in discovering investment opportunities through premium and discount phenomena, a common strategy among seasoned investors.

What is an ADR? A Simple Yet Powerful Custody Mechanism

ADR stands for American Depositary Receipt, issued by US depositary banks representing foreign stocks. Simply put, when foreign companies like TSMC or Hon Hai want to raise funds in the US securities market, they deposit their shares with a US depositary bank, which then issues ADR certificates for investors to trade.

This mechanism may seem complex, but it’s actually very elegant. Take TSMC (TSM.US) as an example: Taiwanese companies are already listed in their home country, but if they want to enter the US market, instead of going through a complicated secondary listing, they can use the ADR route. For investors, buying TSMC ADRs is equivalent to buying TSMC shares in the US, which can be traded directly on the NYSE under SEC regulation.

In simple terms, we can understand ADR as a proxy certificate issued by foreign companies for trading on US stock markets, with trading methods identical to regular US stocks.

Many Types of ADRs, Varying Risk Levels

Not all ADRs are the same. Based on the issuer and regulatory oversight, ADRs are divided into Sponsored ADRs and Unsponsored ADRs.

Sponsored ADRs are issued through agreements between the issuing company and the bank, with the company retaining control and paying fees to the bank. These ADRs usually comply with strict SEC regulations and regularly disclose financial information. In contrast, unsponsored ADRs may be issued without direct involvement from the company, solely by the depositary bank, and are traded only in the over-the-counter (OTC) market. Companies like Tencent (TCEHY.US), BYD (BYDDY.US), and Meituan (MPNGY.US) are examples of unsponsored ADRs, which carry higher risks.

Additionally, ADRs are categorized into three levels based on their access to the US market:

Level 1 ADRs: The least regulated, only for trading purposes, traded OTC, minimal disclosure, highest risk.

Level 2 ADRs: More regulated, full trading capabilities, listed on NASDAQ or NYSE, require filing F6 and 20-F forms.

Level 3 ADRs: The most regulated, used for both trading and fundraising, listed on major exchanges, require multiple filings, lowest risk.

Generally, Level 2 and Level 3 ADRs are more suitable for ordinary investors due to better liquidity and stricter regulation.

ADR Ratios: Key Details Investors Must Know Before Investing

Many beginners overlook a critical issue: ADR does not have a 1:1 exchange ratio with the underlying stock. For example, five shares of Taiwan’s Hon Hai (2317.TW) equal one ADR (HNHPF.US).

The ratio is usually determined based on the foreign stock’s price and exchange rates. If the stock price is too high, affecting liquidity, the company may increase the conversion ratio. Here is a reference table for major Taiwanese companies’ ADR ratios:

The Fundamental Differences Between Taiwan Stocks and Taiwan ADRs

Although they represent the same company, there are important differences between Taiwan stocks and ADRs across multiple dimensions:

Nature: Taiwan stocks are issued by the company itself; ADRs are custody receipts representing those stocks, with entirely different legal attributes.

Trading Jurisdiction: TSMC trades on the Taiwan Stock Exchange under Taiwanese regulation; TSMC ADRs trade on the NYSE under SEC regulation. This means different trading rules, disclosure requirements, and trading hours.

Ticker Symbols: TSMC’s Taiwan stock code is 2330; its ADR code is TSM.

Investor Base: Taiwan stocks are aimed at domestic Taiwanese investors; ADRs target global US investors.

Conversion Ratio: Buying one Taiwan stock equals one share; buying ADRs is subject to the ratio (e.g., 1:5).

Most importantly, the phenomenon of premium and discount: Although Taiwan stocks and ADRs tend to move in the same direction, due to exchange rates, trading volume, and market sentiment, their prices can diverge daily. For example, in early 2023, TSMC’s ADR and Taiwan stock showed similar trends, but their specific price changes and yields often differed. Savvy investors can even profit from arbitrage by exploiting these differences.

The Difference Between A-shares and A-shares ADRs

Similar to Taiwan stocks, A-shares and A-shares ADRs also have fundamental differences. BYD, for example, is listed on China’s A-share market (code 00285) and the US ADR market (BYDDY), but the exchanges, regulatory bodies, and investor groups are completely different. A-shares are for Chinese investors and traded on the Shenzhen and Shanghai exchanges; A-shares ADRs are for overseas investors and traded on NYSE, NASDAQ, or OTC.

Core Factors Investors Must Consider When Investing in ADRs

Liquidity Risk

ADR trading volume is often much lower than that of domestic stocks. For example, China Telecom (CHT.US) has an average monthly trading volume of about 145,000 shares in the US, while its Taiwan stock (2412.TW) averages 12.24 million shares per month. Insufficient liquidity means larger bid-ask spreads and difficulty in executing trades, especially problematic for frequent traders.

Company Fundamentals

Investing in ADRs is similar to investing in other stocks; it requires understanding the company’s operational status, industry outlook, policy environment, etc. Note that Level 1 ADRs do not require US financial disclosures, so investors need to proactively review the financial reports published by the company in its home country.

Arbitrage Opportunities from Premiums and Discounts

The reference value of ADRs is best understood through premium and discount analysis. For example, if TSMC’s ADR price, converted, exceeds the Taiwan stock price, it indicates a premium, reflecting stronger international investor confidence. Conversely, a discount suggests undervaluation. Smart investors can sell ADRs at a premium and buy the underlying stock, or vice versa, to profit from arbitrage.

Advantages and Disadvantages of Investing in ADRs

Main Advantages

Lower Tax Costs: Taiwanese investors can profit from ADRs without paying income tax on gains under NT$1 million. Compared to the transaction taxes and higher fees on Taiwan stocks, ADR trading costs are significantly lower. For high-frequency traders, choosing zero-commission overseas platforms to buy ADRs is more economical.

Diversified Investment Options: The US market is limited to US companies, but through ADRs, you can invest in high-quality global firms. For example, in the electric vehicle sector, you can invest in Tesla (TSLA.US) in the US or NIO (NIO.US) in China, achieving true global allocation.

Main Disadvantages

Complex Process for Non-US Investors: Taiwanese investors need to open overseas brokerage accounts, exchange NT$ to USD, deposit funds, and then trade. Compared to directly buying US stocks, this involves extra costs and steps. Using Taiwanese brokers to purchase ADRs often incurs 1-2% high handling fees.

Exchange Rate Risks: ADRs are traded in USD; fluctuations in TWD/USD directly impact returns. An investor gains 20% profit in USD, but if the USD depreciates during the period, the final converted TWD may result in no profit or even a loss. If third-country currencies are involved, exchange rate volatility becomes even more complex.

Conclusion: Rational Evaluation and Seizing ADR Investment Opportunities

As a tool connecting global capital markets, ADRs hold significant reference value for investors. They provide foreign companies with a convenient US financing channel and offer investors diversified allocation options. However, ADRs are not risk-free investments—liquidity risk, currency risk, and ratio risk all require careful consideration.

The key to investing in ADRs is: understanding their nature, mastering the premium and discount mechanisms, assessing your own risk tolerance, and choosing the appropriate ADR level. Only by deeply understanding these mechanisms can you navigate the global capital markets with confidence.
