This guide will delve into the significance, types, and the impact of these indices on the global economy.
What Are World Equity Indices?
World equity indices are composite measures of the performance of a selected group of stocks from different countries. They are designed to reflect the overall movement of the stock market and are used as benchmarks for investment performance. Some of the most well-known global equity indices include the S&P 500, the FTSE 100, the Nikkei 225, and the MSCI World Index.

The S&P 500 is a stock market index that tracks the performance of 500 large companies listed on the stock exchanges in the United States. It is widely regarded as a proxy for the U.S. stock market and is a key indicator of the broader economic health of the country.
The FTSE 100: The UK's Flagship
The FTSE 100 is a stock market index that represents the 100 largest and most liquid companies listed on the London Stock Exchange. It provides a gauge of the UK's economic health and is often considered a benchmark for the British stock market.

Case Study: The 2008 Financial Crisis
The 2008 financial crisis is a prime example of how world equity indices can impact the global economy. As the crisis unfolded, major indices like the S&P 500 and the FTSE 100 plummeted, leading to widespread panic and a global economic downturn.
