Understanding the Weighted S&P 500 Index

The S&P 500 Index, introduced in 1957, comprises 500 of the largest publicly traded companies in the United States. Unlike other market-capitalization-weighted indices, the Weighted S&P 500 Index employs a unique weighting scheme that gives greater prominence to larger companies.

Calculation Methodology

Each company’s weighting is determined by its market capitalization, which is calculated by multiplying its share price by its number of outstanding shares. Larger companies, such as Apple, Amazon, and Microsoft, carry a more significant weight within the index. This weighting scheme ensures that the index’s performance is primarily influenced by the behemoths of the U.S. stock market rather than smaller companies.
