The Importance of the S&P 500

By tracking these companies, investors can gain insights into the broader economic trends and market conditions.
How Companies Are Selected
The S&P 500 index is carefully curated to ensure it represents a broad cross-section of the U.S. economy. Companies are selected based on several criteria, including their market capitalization, liquidity, and financial stability. The index is reviewed and rebalanced periodically to reflect changes in the market.
