1.7What is a share?

1What is it?

A share is one single unit of ownership in a company. If a company is divided into 1,000 equal pieces, each piece is one share.

2Why does it exist?

Dividing ownership into equal units makes it simple to calculate who owns how much, to share profits fairly and to trade small pieces.

3Real-life example

Think of a pizza cut into 8 equal slices. Each slice is one share. If you own 2 slices, you own 2/8 = 25% of the pizza. If the pizza becomes more valuable (say a famous chef signs it), each slice becomes more valuable too.

4Stock market example

Reliance Industries has over 1,300 crore shares. If you own 10 shares, you own a tiny fraction of Reliance, but you still legally own part of it.

A pizza with 8 slices: owning 2 slices = 25% ownership.
6Calculation
Ownership % = Your shares ÷ Total shares × 100
  1. Your shares = 2, total = 8
  2. 2 ÷ 8 = 0.25
  3. 0.25 × 100 = 25%
You own 25%.
