What Is the P/E Ratio? Is Aman's Bakery Too Expensive?

2.1 — "Good business" and "good investment" are not the same sentence

The question from the meeting wouldn't leave her alone. Riya put it to Raj directly: how do you tell whether a share price is too high, when the accounts only tell you what the company earns?

"By comparing the two," he said. "That's the entire trick, and it's a division sum. A price on its own means nothing. A ₹150 share isn't cheaper than a ₹3,000 one — you don't know what you're getting for either number until you ask what the company earns behind it."

2.2 — The division sum

**P/E** stands for **Price-to-Earnings**. Take the share price and divide it by the company's **earnings per share** — its profit, divided across every share in existence. What comes out is how many rupees investors are currently paying for each rupee of annual profit.

Raj worked the example on the back of the meeting agenda. A ₹150 share, a company earning ₹10 per share in a year. 150 ÷ 10 = 15. "Investors are paying fifteen rupees for every one rupee of yearly profit. Hold it long enough and, at that rate of earnings, it takes fifteen years of profit to add up to what you paid."

"That sounds like a lot."

"Compared to what?" He let the question stand. "That's the only sensible response to any P/E. It's a comparison tool. It tells you nothing in isolation."

2.3 — Two bakeries, identical profit, double the price

Suppose a rival chain also lists, at ₹300 a share, and earns the same ₹10 per share. Its P/E is 30 — investors are paying exactly twice as much for an identical rupee of profit.

"So the rival is overpriced," Riya said, reaching for her phone.

"Or the market thinks it's about to grow much faster, and is paying in advance for profits it expects in three years rather than this one." Raj shrugged. "A high P/E is an expectation. It might be right. What you can say for certain is that a company priced for rapid growth has further to fall if the growth doesn't arrive — because the price wasn't supported by today's earnings in the first place."

This is why a P/E only means something *against* something: a direct competitor, the same company's own history, or the broader market. A P/E of 30 might be alarming for a mature, slow-growing bakery chain and entirely unremarkable for a fast-growing technology business.

2.4 — Riya checks her own holding for the first time

It took her about four minutes, that evening, to do a thing she had never done in four years of owning the stock.

She took Aman's current share price. She took the earnings per share from the accounts she'd finally read. She divided one by the other.

The number was a great deal higher than 15. It had been 15 once — around the time she'd first bought, which she'd assumed was a coincidence of timing rather than the reason her holding had done so well. Every month since, she had bought more, at a steadily rising price, against earnings that had grown more slowly than the price had.

She sat with that for a while. Then she did something she'd later find difficult to defend.

2.5 — The rationalisation

She checked the rival chain's P/E. It was higher than Aman's.

That settled it, she decided. Relatively speaking, the bakery was the cheaper of the two. She had compared it to something, which was the rule Raj had given her, and the comparison came out favourable. She closed the laptop.

It is worth being precise about what she'd just done, because it is extremely common. She had used a real tool, correctly, and then chosen the single comparison most likely to produce a comfortable answer. She had not compared the bakery to its own P/E three years ago. She had not compared it to the market. She had not asked whether both bakeries might be expensive at the same time. She had gone looking for permission, and found some.

She did not mention any of this to Raj, which she would also, later, find difficult to defend.

2.6 — The cheap stock she nearly bought instead

A month later she found something with a P/E of 4. Four. A fraction of anything else on her screen, in a company that sounded perfectly ordinary.

This time — and this genuinely was progress — she didn't call Raj to ask whether to buy it. She went and found out *why* it was cheap first. It took an hour and the answer was on the second page of the company's own filings: its main product had been comprehensively overtaken by a competitor's, and its largest customer had not renewed.

The market hadn't mispriced it. The market had priced in profits that were about to fall off a cliff, and the P/E looked low only because it was still dividing by last year's earnings.

She told Raj about it, rather pleased. He was pleased too — genuinely. It didn't occur to either of them, in that conversation, that she had just done careful diligence on a company she didn't own while skipping it entirely on the one holding most of her money.

2.7 — What the ratio can't see

One more limit, which matters. A P/E says nothing about debt, nothing about cash flow, and nothing about how the profit was earned. Remember the three statements from the last chapter: each hides something the others catch. The P/E sits on top of only one of them — the income statement. A company with a comfortable P/E and a dangerous balance sheet will look perfectly reasonable on this one number alone.

2.8 — The problem of too much money

The call from Aman, a few weeks later, was about a problem Riya initially struggled to take seriously.

The five branches had opened. They were working. The bakery had paid down its borrowings, funded the expansion out of its own takings, and was now sitting on roughly ₹2 crore of cash with nothing immediate to spend it on.

"I have a board meeting on Thursday," Aman said, "and apparently this is a decision. It doesn't feel like a decision. It feels like a good year."

"What's the argument?"

"Half of them want to send it to the shareholders. The other half want to use it to buy our own shares back off the market." A pause. "Riya, you're a shareholder. Which would you rather I did?"

She realised she had no idea, and worse, no idea why anyone would prefer the second one.

2.9 — The real world translation
