How the S&P 500 is Calculated

The S&P 500 Index is calculated using a market-capitalization-weighted formula, meaning larger companies have a bigger influence on the index’s movements.

S&P 500 Calculation Formula:

$$\text{Index Value} = \frac{\sum \text{Market Cap of 500 Stocks}}{\text{Divisor}}$$

✔ Market Cap: Stock price × Outstanding Shares
✔ Divisor: Adjusted for stock splits, dividends, and index rebalancing

📌 Example: If Apple’s market cap rises, it significantly impacts the index compared to smaller companies like Ford or McDonald’s.
