The US30 otherwise known as the DJ30 or just Dow is a price-weighted stock market index that measures the performance of the 30 largest publicly owned companies listed on the New York Stock Exchange. Unlike most global indices that are a weighted average of the market capitalizations, the Wall Street 30 is a price-weighted average. It was founded by Wall Street Journal editor Charles Dow and was first calculated on May 26, 1896, making it one of the oldest stock indexes. The 30 stocks in its listing can dictate the movement of the entire stock market. It is considered as a strong indicator of the US economy and is one of the most monitored and regularly cited stock indexes in the world. The stocks forming the Dow Jones 30 Index range from diverse sectors including industrial, healthcare, consumer services, technology and more. The composition of the index varies with time as stocks and industries represented fall in and out of favor.
