Decrypting US Stock Advantages: The Underlying Logic of Institutional Dividend, Global Capital, and Long-Term Returns

In recent years, global capital has continued to pour into the US stock market, making Wall Street a "safe haven" and a source of returns for global investors. From the record-breaking performance of the S&P 500 index to the AI revolution led by tech giants, the appeal of the US stock market stems not only from its massive scale but also from its unique institutional dividend and long-term stable return logic. This article will unravel the underlying logic of US stock market advantages from dimensions such as market mechanisms, investment products, and return performance, providing investors with in-depth references. ## I. Mature Market Mechanisms: The "New Metabolism" System of Winners and Losers One of the core advantages of the US stock market is its efficient exit mechanism and strict regulatory system. Compared to the A-share market, the exit system in the US market is more market-oriented, with an average exit rate exceeding 8%, far higher than the A-share market's around 1%. This "winners and losers" mechanism ensures the optimal allocation of market resources, allowing high-quality companies to receive more funding while eliminating lagging capacity. For example, in 2025, over 300 companies in the US market exited, most due to poor performance or regulatory violations, while over 500 new listings occurred, keeping the market vibrant. Furthermore, the regulatory transparency of the US market is another advantage. Strict regulation by the SEC (Securities and Exchange Commission) ensures the timeliness and accuracy of information disclosure, allowing investors to obtain the true operating status of companies. For instance, in 2026, the SEC's antitrust investigation into tech giants, although causing short-term market fluctuations, enhanced market fairness and transparency in the long run, protecting the interests of small investors. This regulatory environment instills confidence in investors, encouraging long-term participation. ## II. Rich Investment Products: The "Toolbox" Satisfying Diverse Needs The investment products in the US stock market are extremely rich, ranging from stocks, ETFs, options to futures, covering almost all investment needs. The popularization of ETFs (Exchange-Traded Funds) lowers the barrier to entry for investors, allowing retail investors to easily invest in specific sectors or indices. For example, the S&P 500 ETF (SPY) is one of the largest ETFs globally, tracking the S&P 500 index. Investors can purchase SPY to achieve diversified investment and reduce single-stock risk. The convenience of this tool allows investors to share in overall market returns without needing to conduct in-depth research on individual stocks. Moreover, the options market in the US is highly developed, allowing investors to use options for hedging or speculation. For example, in 2026, with increased volatility in tech stocks, many investors used put options to hedge against stock price declines. The activity in the options market not only provides investors with risk management tools but also injects liquidity into the market. Statistics show that option trading volume in the US market increased by 15% year-over-year in the first half of 2026, reaching a new historical high. ## III. Long-Term Stable Returns: The "Compound Engine" Crossing Cycles The long-term return performance in the US stock market is a key factor in attracting global capital. According to historical data, the average annual return of the S&P 500 index over the past 50 years is approximately 9.2%, significantly higher than other major global markets. This stability in long-term returns stems from the resilience of the US economy. For example, despite the COVID-19 pandemic in 2020 and inflationary pressures in 2022, the S&P 500 index maintained an upward trend in the long term. This ability to cross market cycles allows investors to ignore short-term fluctuations and focus on long-term returns. In addition, stock buyback culture in US stocks is also an important source of returns. Many companies increase earnings per share by buying back stocks, thereby driving stock prices up. For example, Apple's buyback amount in 2025 exceeded $100 billion, and Microsoft's buyback amount also exceeded $80 billion. This shareholder return culture provides investors with additional returns. According to statistics, in 2025, the total amount of buybacks by US companies reached $12 trillion, a historical high, accounting for over 30% of net income. ## Four, Liquidity and Global Capital: A Year-Round "Money Pool" The liquidity in the US stock market is the strongest globally, with huge trading volumes, small bid-ask spreads, and investors can buy or sell stocks at any time. For example, the average bid-ask spread for S\&P 500 constituent stocks is only 0.05%, far lower than in other markets. This high liquidity allows investors to quickly enter and exit the market, reducing trading costs. Furthermore, the "all-weather" trading mechanism in US stocks allows global investors to participate in the market. For example, the T+0 trading system (for some stocks) and overnight trading windows allow investors to trade outside of regular market hours, meeting the needs of different time zones. This mechanism makes the US stock market a "money pool" for global capital, attracting investors from Asia, Europe, the Middle East, and other regions. Continuous inflow of global capital is also a major support for the US stock market. According to data from the Federal Reserve, in the first half of 2026, foreign investors purchased US stocks totaling over $500 billion, with Asian investors accounting for about 30%. This inflow of global capital not only drives stock price increases but also enhances market stability. For example, in July 2026, foreign net purchases of S\&P 500 constituent stocks exceeded $20 billion, driving the index to a new historical high. ## Five, Investment Strategy Recommendations: A "Practical Guide to Seizing Advantages" For investors, it is necessary to take appropriate strategies to fully utilize the advantages of US stocks. First, long-term holding is key. US stocks offer stable long-term returns, but short-term volatility is high; long-term holding can avoid emotional trading and achieve compound returns. For example, Warren Buffett's investment philosophy is to hold quality companies long-term and enjoy the dividends of business growth. Statistics show that Berkshire Hathaway, under Buffett's umbrella, has an average annual return of about 20% over the past 50 years, far exceeding the market average. Second, diversification is necessary. By purchasing ETFs or investing in different sectors, investors can reduce individual stock risk. For example, investors can hold technology ETFs, healthcare ETFs, and consumer ETFs simultaneously to diversify industry risk. This diversification prevents the fluctuation of a single sector from affecting the overall investment portfolio. For example, in August 2026, technology stocks experienced a pullback, but consumer ETFs remained stable, diversifying investor risk. Finally, focus on core assets. Core US stocks, such as tech giants (Apple, Microsoft, Google), consumer leaders (Coca-Cola, McDonald's), and financial giants (JPMorgan, Goldman Sachs), have stable performance and growth potential, making them good choices for long-term investment. For example, Apple's service revenue proportion is continuously increasing, reaching 25% in 2025, becoming a new growth engine. Such core assets possess a strong moat that can withstand market fluctuations. In summary, the advantages of the US stock market lie in its mature mechanisms, rich variety, stable returns, and its attractiveness to global capital. For investors, understanding these advantages and adopting appropriate strategies is necessary to achieve long-term returns in the US stock market. In the future, with the continued development of the American economy, the US stock market will remain the first choice for global investors.
