What are Indexes?
Financial indices are aggregated (pooled together) statistical measures used to track the performance of a particular sector or market. An index is created by selecting a group of securities representing a particular market or industry and then measuring the overall performance of those securities over time. The value of an index is typically calculated using a weighted average of the prices of the securities included in the financial measure.
Investors use indices as a way to track the performance of a broader country or specific sectors, and to compare the performance of their own portfolios to the average performance of the index. This data can be used to provide a benchmark for the performance of a particular stock or investment, or to assess the performance of a particular market or sector.
For example, the S&P 500 index is a widely followed index in the United States that tracks the performance of the country's 500 largest publicly traded companies. By tracking the performance of the S&P 500, investors can get a sense of the overall health of the U.S. stock market.

NASDAQ Composite: includes over 2,500 stocks, mostly U.S. technology and IT companies, listed on the NASDAQ exchange.
FTSE 100: tracks the 100 largest companies by market capitalization listed on the London Stock Exchange.
Nikkei 225: represents 225 blue-chip stocks on the Tokyo Stock Exchange and serves as a barometer of the Japanese stock market.

In summary, using indices can be useful for investors, as they allow them to track the economic performance of a country or specific sectors without the need to analyze individual stocks or investments. By investing in index funds or exchange-traded funds (ETFs) that are "tied" to specific indices, investors can gain the opportunity to earn passive income with minimal effort and expense.
