World market indices are a set of stock market indices that measure the value of the stock markets in different countries around the world. These indices are used to compare and analyze the performance of global markets, and can be used as a benchmark for investors to make buying and selling decisions for their portfolio.

The major world indices include the Dow Jones Industrial Average, S&P 500, NASDAQ Composite Index, MSCI World Index, and FTSE Global Markets Index. These indices track stocks from different countries and regions across the globe, providing investors with an overview of market conditions in comparison to other markets.

Investors use these indices to identify potential opportunities in different markets and make informed decisions about their investments. For example, if one index is performing better than another, this could indicate that there may be more potential for growth in that particular market. Additionally, these indices can provide insight into global economic trends and help investors understand how different countries are performing compared to each other.

Always do your own research before investing in any assets, whether this is stocks, futures, bonds, forex or cryptocurrencies.
