Reading PER and PBR together: priced low, or low for a reason

PER measures the share price against earnings and PBR against net assets. Read together they reveal more than either alone, and a stock that looks priced low often has a reason for it.

Valuation reads the price tag, not the company

If the grade asks whether a company's finances are sound, valuation asks whether the current share price is high or low relative to that company. A good company and a low price are different questions: a good company can trade at a high price, and an ordinary company can trade at a low one.

PER (price to earnings ratio) and PBR (price to book ratio) are the best-known valuation metrics. Both express the share price as a multiple of something; PER measures it against earnings, PBR against net assets.

This is why Jupick does not include either in the overall grade and shows them separately on the stock page. Mixing financial strength (the grade) and price level (valuation) into one number blurs which story is being told.

PER: how many times earnings

PER is the share price divided by earnings per share. A PER of 10 means the current price is about 10 times the net income the company earns in a year.

A lower value means paying less for the same earnings, but it can also be a sign that the market expects weaker future earnings from the company. That is why a low PER cannot be taken as proof that a stock is priced below its worth.

Loss-making companies have negative earnings, so PER cannot be calculated, and when net income is inflated by a one-off gain such as a property disposal, PER can look misleadingly low. So the quality and trend of earnings need to be checked as well.

PBR: how many times net assets

PBR is the share price divided by net assets (equity) per share. A PBR of 1 means the price equals the company's net assets on the books; below 1 means it trades for less than its net assets.

It means the most at banks and manufacturers, where assets are the basis of earnings, and it is hard to judge by PBR alone at companies with few assets whose core is a brand or technology.

A low PBR does not automatically mean a stock is priced below its worth. When the real value of the book assets is lower than stated, or those assets do not produce adequate earnings, the market puts a price below net assets.

What the pair shows together

Reading PER and PBR together reveals traits that one metric alone misses. If both are low, the market rates the company low across the board; if both are high, high expectations are already reflected in the price.

A low PER with a high PBR can mean a company that earns well on few assets; a low PBR with a high PER can mean a company with plenty of assets but weak recent earnings.

That is why Jupick shows PER and PBR side by side on the stock page. Looking at the relationship between two numbers rather than one gives a fuller understanding of the current price.

When a stock looks priced low

When a metric is low and a stock looks priced low, there is often a reason. The market tends to price in known bad news and low growth expectations first. Judging a stock as priced low from the metric alone and then getting burned is commonly called a value trap.

Valuation is not the final answer on high or low but a starting point for asking why the price is what it is. The numbers gain meaning only alongside a comparison with the sector average, the trend in earnings, and whether financial strength (the grade) backs them up.

Jupick's theme lists such as “low PER stocks” are simply sorted by the metric from lowest up; they are not trading advice. Checking why a value is low is the user's own job. This content is for information only and is not investment advice.

Frequently asked questions

What does PER measure?
PER is the share price divided by earnings per share; a PER of 10 means the current price is about 10 times the net income the company earns in a year. A lower value means paying less for the same earnings, but it can also signal that the market expects weaker future earnings from the company. Loss-making companies have negative earnings, so PER cannot be calculated.
What does PBR measure?
PBR is the share price divided by net assets per share; a PBR of 1 means the price equals the company's net assets on the books, and below 1 means it trades for less than its net assets. It means the most at banks and manufacturers, where assets are the basis of earnings, and is hard to judge alone at companies whose core is a brand or technology. A low value does not automatically mean the stock is priced below its worth.
Does a low PER or PBR mean the stock is priced below its worth?
Not necessarily. When a metric is low and a stock looks priced low, there is often a reason, such as known bad news or low growth expectations already priced in. Judging a stock as priced low from the metric alone and then getting burned is called a value trap. Valuation is not the final answer on high or low but a starting point for asking why the price is what it is.
