What is a P/E Ratio? Explained Simply (2026)
Investing explained in plain English, through sports.
The P/E ratio is one of the first numbers serious investors look at. But most explanations make it more confusing than it needs to be. Here's the simple version.
THE PLAIN ENGLISH DEFINITION
P/E stands for Price-to-Earnings. It tells you how many years of current profits you're paying for the company.
A P/E of 20 means you're paying 20 times what the company currently earns in a year. A P/E of 50 means you're paying 50 years' worth.
THE SPORTS ANALOGY: TRANSFER FEES
Think of it exactly like a football transfer fee.
If a striker scores 20 goals a year and you pay £40m for them, you're paying £2m per goal — a P/E of 2. If you pay £80m, the P/E doubles to 4. The question is whether future performance justifies the premium.
A high transfer fee (high P/E) says: "I believe this player will produce even more goals in the future." A low transfer fee (low P/E) might mean the player is undervalued — or that the market sees something wrong that you don't.
HIGH P/E vs LOW P/E — WHICH IS BETTER?
| TYPE | TYPICAL P/E | WHAT IT SIGNALS | EXAMPLE |
|---|---|---|---|
| High-growth tech | 40-100x+ | Market expects massive future growth | NVDA (72x), PLTR (90x) |
| Steady blue chip | 20-35x | Reliable, predictable, priced fairly | AAPL (29x), MSFT (32x) |
| Mature/value | 10-20x | Slower growth, cheaper entry | JPM (12x), KO (22x) |
| Turnaround/troubled | Single digits | Market is sceptical about earnings | INTC (12x), PFE (14x) |
| No P/E (N/A) | — | Company isn't profitable yet | RIVN, RBLX, PLTR |
WHAT P/E DOESN'T TELL YOU
P/E is backwards-looking — it uses last year's earnings. A high-growth company with a 60x P/E might look cheap in two years if earnings triple. A low P/E company might be a trap if earnings are about to collapse.
This is why investors also look at the PEG ratio (P/E divided by growth rate) — it adjusts the P/E for how fast the company is growing.
QUICK EXAMPLES FROM THE PLATFORM
- NVDA at 72x P/E — eye-wateringly expensive. But 265% revenue growth means the earnings denominator is growing fast. The question is whether it stays that high.
- V (Visa) at 27x P/E — reasonable for a company growing 10-12% with a near-monopoly business model.
- JPM at 12x P/E — cheap for the best-run bank on earth. Cyclical, but if you think the economy stays strong, this is a bargain.
