The true size of the global stock market can be hard to quantify, although the total market cap of all publicly traded companies in 2020 was approximately $93 trillion.
Interestingly, the global stock market is home to both indices and individual stocks, the former which enable you to invest in an entire basket of equities and achieve instant diversification (minimising your exposure and immediate risk in the process.
But what’s the combined size of the stock index marketplace, and what are the leading three indices for investors to consider?
How Big is the Stock Index Marketplace?
Not only do stock market indexes enable investors to target a diverse selection of equities in different industries and countries, but they also serve as powerful and insightful indicators for global and country-specific economies.
In the US alone, there are approximately 5,000 individual indexes, including three of the most widely followed in the form of the S&P 500, Dow Jones Industrial Average and the Nasdaq Composite.
In total, the total market capitalisation value of these US stock indexes is thought to be in the region of $48 trillion, at least during the first quarter of 2021.
One of the best gauges of the cumulative market is the Wilshire 5000 Index, which includes all stocks from the US market and is widely followed through the MT4 platform in the Forex market.
