US30The Dow Jones Industrial Average (US30) is a stock market index that tracks 30 of the largest and most established blue-chip companies in the United States. Unlike the NAS100 and SPX500, which are market-cap-weighted, the US30 is price-weighted, meaning stocks with higher prices have more influence on the index. It includes major corporations like Apple, Boeing, Goldman Sachs, and Microsoft, covering industries such as finance, technology, healthcare, and manufacturing. The US30 is considered a key indicator of economic health, often reacting to macroeconomic data, Federal Reserve policies, and geopolitical events.
