Index

What Is an Index?

An index is a statistical measure that tracks the performance or value of a group of assets, such as stocks, bonds, or interest rates. It is often used as a benchmark.

Why It Matters

Indexes help investors measure performance, track market trends, and make informed investment decisions. They are also used to set interest rates on certain financial products.

How an Index Works

Indexes typically:

• track a selected group of assets
• use weighted calculations
• reflect market performance
• serve as benchmarks for funds
• influence financial products (like adjustable-rate loans)

Example

The S&P 500 is an index tracking 500 large U.S. companies to reflect stock market performance.

Index vs Benchmark

• Index is a specific measurement tool.
