What Are PER, PBR & ROE? Learn Stock Fundamentals Through a Game

Published: July 9, 2026

01

What Are Fundamentals?

Fundamentals are a way of judging whether a stock is cheap or expensive, and whether a company is financially stable, based on its earnings and financial statements. Where technical analysis reads price charts for timing, fundamental analysis looks at the substance of the company itself.。

It sounds intimidating, but really you only need to know a handful of core metrics. Once you grasp what they mean and roughly what a 'normal' value looks like, you'll have far more to go on when picking stocks.。

The Key Metrics, Explained

PER (Price-to-Earnings Ratio)

How many times a company's annual profit the current share price represents. Lower generally means cheaper; for Japanese stocks, around 15x is often cited as a rough benchmark, though it varies a lot by industry.。

PBR (Price-to-Book Ratio)

Compares the share price to the net assets that would theoretically be returned to shareholders if the company were liquidated today. Below 1x means the stock trades below its 'liquidation value' — a common signal of being undervalued.。

ROE (Return on Equity)

How efficiently a company turns shareholders' capital into profit. Higher is generally better, with 8–10% or above often cited as a healthy benchmark.。

Equity Ratio

The share of a company's total assets funded by equity rather than debt. A higher ratio suggests less reliance on borrowing and a more stable balance sheet; 40% or above is often seen as relatively solid.。

Dividend Yield

The annual dividend as a percentage of the share price. A higher yield looks attractive for income-focused investors, but a very high yield can also signal risk of a future dividend cut if earnings deteriorate.。

Market Cap

Share price multiplied by shares outstanding — the market's total valuation of the company. Larger market caps tend to move more calmly; smaller ones tend to swing more.。

PBR1x is the cheap/expensive threshold
ROE8–10%+ signals good efficiency
Equity Ratio40%+ is relatively stable
Dividend YieldHigher is attractive, but watch for cut risk
Market CapLarger caps tend to move more calmly

Why 'Learning by Using' Beats Memorizing

Definitions alone rarely make these numbers click. It's only when you compare PER or PBR across several companies and ask 'is this one cheap relative to its peers?' that the numbers start to mean something.。

Fundamentals are rarely judged from a single metric in isolation — you weigh several together. That's exactly why comparing real numbers side by side is the fastest path to real understanding.。

FAQ

Which matters more, PER or PBR?

Neither alone is enough — combining several metrics for an overall judgment is the recommended approach.

How long does it take to learn to read these metrics?

It varies, but comparing real numbers across companies typically builds a working intuition within a few weeks for most people.
