The three major US indices — the Dow Jones Industrial Average (DJIA), the S&P 500, and the Nasdaq Composite — are important barometers for global stock markets. These indices not only reflect the overall performance of the US economy but also have a profound impact on global financial markets. For investors, keeping an eye on the movements of these indices helps to grasp market trends and formulate more effective investment strategies.
The Dow Jones Industrial Average is one of the oldest stock market indices in the US, comprising 30 representative blue-chip industrial stocks. The index is calculated using a price-weighted method, meaning that companies with higher stock prices have a greater influence on the index. Representative companies include Apple, Goldman Sachs, and Visa. The DJIA primarily reflects the performance of traditional industries, making it suitable for investors focused on economic outlooks.
The S&P 500 includes the 500 largest companies by market capitalization in the US, and it is calculated using a market-capitalization-weighted method. The index covers a wide range of industries, including technology, healthcare, finance, and energy, and is considered a representative index of the US stock market. Institutional investors often use the S&P 500 as a benchmark for investment performance due to its high representativeness and stability.
The Nasdaq Composite includes all the stocks listed on the Nasdaq exchange, totaling over 3,000 companies, with a strong emphasis on technology stocks. The index’s high volatility and growth potential attract many investors. Representative companies include Apple, Amazon, Meta, Tesla, and NVIDIA. The Nasdaq index is suitable for investors focusing on emerging industries and technological innovation trends.

The volatility of the three major U.S. indices has a pull effect on global markets. For example, major economic data releases (such as CPI, employment data) or policy changes (such as interest rate hikes or tax cuts) can impact the performance of the indices, which in turn affects other markets like Taiwan and Asia. Furthermore, sharp declines in the indices may trigger market risk aversion, pushing assets like gold, U.S. Treasuries, and the U.S. dollar to strengthen.
