S&P 500 vs. Dow Jones Industrial Average
While both the S&P 500 and the Dow Jones Industrial Average (DJIA) are prominent U.S. stock market indices, they differ in several aspects:
- Number of Constituents: The S&P 500 includes 500 companies, whereas the DJIA comprises only 30.
- Weighting Methodology: The S&P 500 is market-cap-weighted, giving more influence to larger companies. The DJIA is price-weighted, meaning companies with higher stock prices have more impact.
- Sector Representation: The S&P 500 offers broader sector representation, while the DJIA focuses on established blue-chip companies.
These differences make the S&P 500 a more comprehensive reflection of the U.S. stock market.
