For example, the S&P 500 is considered a leading indicator of the US economy, and is widely followed by investors and financial analysts around the world. Similarly, the Nifty 50 is a key benchmark for the Indian stock market, and is closely watched by investors and policymakers in India.
Here's a brief overview of each index:

How Do the S&P 500, Nifty 50, STI, and NZX 50 Work?
Each of these indexes is calculated using a different methodology, but they all aim to provide a representative sample of the performance of their respective stock markets.

The STI and NZX 50 are also calculated using market-capitalization-weighted methodologies, but they have different constituent stocks and weighting schemes.
Here's a comparison of the four indexes:
| Index | Constituent Stocks | Weighting Scheme |
|---|---|---|
| S&P 500 | 500 US companies | Market-capitalization-weighted |
| Nifty 50 | 50 Indian companies | Free-float market-capitalization-weighted |
| STI | 30 Singaporean companies | Market-capitalization-weighted |
| NZX 50 | 50 New Zealand companies | Market-capitalization-weighted |
