Core Viewpoint - The article discusses the differences between direct investment in U.S. common stocks and indirect investment through American Depositary Receipts (ADRs), highlighting the significance of understanding these differences for investors. Group 1: Differences in Issuance and Ownership - U.S. common stocks are issued directly by U.S. or foreign companies to investors, representing direct ownership, while ADRs are issued by U.S. depositary banks and represent shares of foreign companies, leading to indirect ownership [1]. - Common stocks are listed on U.S. exchanges like the NYSE or NASDAQ, whereas ADRs are traded on U.S. exchanges but are based on foreign stocks [1]. Group 2: Transaction Costs and Mechanisms - Investors in U.S. common stocks incur standard transaction costs such as commissions and regulatory fees, while ADRs may involve additional fees from depositary banks, including deposit service fees and dividend conversion fees [2]. - ADRs are categorized into different levels (Level 1, Level 2, Level 3), each with varying trading scopes and disclosure requirements, unlike common stocks which do not have such classifications [2]. Group 3: Shareholder Rights - Shareholders of U.S. common stocks can directly exercise their voting and dividend rights, while ADR holders must go through depositary banks to exercise these rights, making the process more complex [2]. Group 4: Regulatory and Disclosure Requirements - U.S. common stocks are subject to strict regulations by the SEC and must disclose financial reports according to GAAP, while ADRs must comply with both U.S. regulations and those of their home countries [3]. - Disclosure requirements for ADRs vary by level, with Level 3 ADRs needing to submit comprehensive reports similar to U.S. companies, while Level 1 ADRs have simplified disclosure requirements [3]. Group 5: Liquidity Performance - The liquidity of U.S. common stocks is determined by their market activity, with larger companies typically having better liquidity [3]. - The liquidity of ADRs depends on the market recognition, size, and trading demand of the corresponding foreign companies, with some leading companies' ADRs having liquidity comparable to common stocks, while smaller companies' ADRs may have lower liquidity [3].
