The half that gets left out
A share price is what one slice costs. How big the whole thing is depends on how many slices there are — and companies choose wildly different numbers of slices.
Bharat Foods trades at ₹500 with one crore shares. That makes the whole company worth ₹500 crore. Now take a company whose shares cost eight times as much, ₹4,000, but which only ever issued two lakh of them. The whole of that company is worth ₹80 crore.
- Bharat Foods Ltd
- ₹500 × 1,00,00,000 shares
- The other company
- ₹4,000 × 2,00,000 shares
The cheaper share belonged to the company six times larger.
Why the slice count varies so much
Nothing forces a company towards a particular price. A business can split each share into ten, and the price falls to a tenth overnight — same company, same assets, same profits, ten times the shares.
If Bharat Foods did that tomorrow, its shares would trade near ₹50 and there would be ten crore of them. Nothing about the business would have changed. Anyone reading the ₹50 as a sign of decline would simply be wrong.
Hold the price still and change the company
The share price below never moves. Drag the share count and watch the company grow and shrink underneath it.
This is why comparing two companies by share price is meaningless. You are comparing one factor out of two.
None of this makes price useless. It tells you exactly what one share costs you today, and that is the number you hand over. It just cannot be compared across companies.
Company A trades at ₹80 and Company B at ₹1,600. Which is bigger?
The multiplication that fixes this has a name, and it is the number quoted in every headline about a company's size.
