The US 30 index represents the value of the 30 largest US-registered corporations, also known as the Dow Jones index. It is one of the most-watched indices in the world because of the short list of companies it represents.
The US 30 has a price-weighted average, meaning companies with the highest share price exert the most influence on the index. As of August 2022, UnitedHealth Group Inc. sits at the top with just over 10% of the index’s total weight.
What affects the US 30 price?
The US 30 price is affected by general uncertainty around major world economic influences such as energy prices, war, political unrest, and tariffs. Economic data from the US is also a major influence on the US 30. This includes decisions made by the Federal Open Market Committee (FOMC), unemployment rates, inflation, and geopolitical events that involve the US.
