Definition of Index

The performance of a group of connected things or variables through time is tracked and compared using indices, which are numerical representations or statistical measures.
It offers a uniform method for evaluating and analyzing changes in a variety of variables, like as prices, values, or indicators, within a given context or market.

Understanding index

Imagine you have a collection of things, like trading cards or toys.
Now, let’s say you want to keep track of all the things in your collection, but it’s becoming hard to remember everything you have. That’s where an index comes in.
An index is like a special list or catalog that helps you organize and find things easily. It usually has names, numbers, or other symbols that represent the different items in your collection.
For example, you could have an index that lists all your trading cards by their names or numbers.
When you want to find a specific trading card, you can look at the index to see where it is. It tells you which page or section to go to so you can quickly find the card you’re looking for.
This way, you don’t have to search through your whole collection each time.
Indexes are used in many other places too, not just for collections. In the financial world, there are indexes that help keep track of how well different companies or industries are doing in the stock market.
These indexes use numbers to show if things are going up or down.
So, think of an index as a helpful guide that makes it easier to find things or understand how something is changing.
It’s like having a map to navigate through your collection or the world of finance!

What is an index fund?

Index funds are a special sort of mutual fund or ETF whose goal is to track the performance of a market index.
