Indices are a popular asset class among traders. An index is a collection of assets that provides traders with an average price to track market or industry price movements easily. The most common type is the stock index, which combines stocks based on company size, industry, or other characteristics.

There are various popular indices globally, with the U.S. hosting some of the most well-known ones, such as the benchmark S&P 500 index, Nasdaq 100, and Dow Jones Industrial 30. Outside the U.S., there are also potential opportunities.

In the U.K., the FTSE 100 and FTSE 250 are popular, focusing on multinational and domestic U.K. companies. Across Europe, traders can find many popular indices, including Germany's DAX 30, France's CAC 40, and Italy's FTSE MiB.
