Criteria for Selecting Companies

Role of Stock Market Indices in Investing
Investors utilize stock market indices as a crucial tool for evaluating the performance of their portfolios and comparing them to the overall market trends. By tracking these indices, investors can make informed decisions about their investments based on the market’s direction.
Benchmarking Portfolios
One common way investors use stock market indices is to benchmark their portfolios against the performance of these indices. By comparing their portfolio returns to the returns of a relevant index, investors can assess how well their investments are performing relative to the broader market.
Investing in Index Funds or ETFs
Investing in index funds or exchange-traded funds (ETFs) that track specific market indices is a popular strategy among investors. These funds offer diversification across a wide range of securities, mirroring the composition of the underlying index. This strategy allows investors to gain exposure to the overall market performance without having to pick individual stocks.
Correlation with Economic Indicators
The performance of stock market indices is often closely linked to various economic indicators, such as GDP growth, inflation rates, and interest rates. Investors pay attention to these indicators to gauge the overall health of the economy and make informed decisions about their investments. A strong correlation between index performance and economic indicators can help investors anticipate market movements and adjust their investment strategies accordingly.
