An index is a measure that tracks the performance of a specific group of securities, such as shares, bonds, or other market instruments. Indexes give investors a single number to understand how that group is performing without looking at each company individually.

You can think of an index like a scorecard for a market or sector. When the companies in the index grow in value, the index moves up. When they fall, the index moves down. This provides a quick and trustworthy approach to assess how the market is performing.

Suppose you invest ₹4,80,000 equally across 48 separate firms. 
 

This means that the combined value of your investments grew by ₹48,000 in a year, or 10%. Also, the index representing those companies would reflect this 10% growth.
