A quoted price describes one share. Comparing that price alone ignores how many shares are outstanding. A fictional two-company calculation shows why a larger unit price can accompany a smaller aggregate market value.

Write both inputs with their units
Assume two imaginary public companies each have a single class of comparable ordinary shares. Company A has a price of 50 currency units per share and two million outstanding shares.
Company B has a price of 10 units per share and twenty million outstanding shares. Use the same currency and observation time so the arithmetic compares like with like.
Multiply before comparing the totals
In this simplified model, A's market capitalisation is 50 × 2,000,000 = 100,000,000 currency units. B's is 10 × 20,000,000 = 200,000,000.
A's per-share price is five times B's, but A's market capitalisation is half B's. The share-count ratio reverses the conclusion that would come from looking only at the quotes.
Check the direction of the calculation
Dividing the fictional aggregate values by their respective outstanding counts recovers the original per-share figures: 100 million divided by two million is fifty, and 200 million divided by twenty million is ten.
This is a useful unit check. Multiplying currency per share by shares produces currency; it does not produce annual revenue or a cash balance. Those measures would need their own information.
Keep the conclusion narrow
The calculation compares one aggregate measure for two fictional companies. It does not establish which business is better, whether a share is attractive or what its future price will be. Real comparisons also require reliable definitions and data, especially where share classes or reporting dates differ.
