The US 30 is based on the leading US benchmark share market index, which contains 30 major companies. These include blue-chip stocks like Apple, Coca-Cola, Goldman Sachs, Microsoft and Visa. The index is one of three major indices within the US and one of the most popularly traded assets worldwide, where each constituent represents a benchmark standard for its industry. It's not calculated by market capitalisation; instead, it’s price-weighted, meaning that the total value of the index reflects the sum of each share of stock, divided by the divisor. Therefore, all components have the same influence on the index’s value. Spread bet or trade CFDs on US 30 - Cash.
