A retail investor opens Meroshare, scans a broker’s tip sheet, and spots a stock trading at a PE of 6. Everything else on the board looks expensive by comparison, so the low number feels like a bargain hiding in plain sight. He buys. Eighteen months later the stock is down a third, the earnings that produced that low PE have collapsed, and the “cheap” number turns out to have been a warning he read as an invitation.
That is the problem with the PE ratio on NEPSE. It is the most quoted number in the market and the least understood. Every portal prints it, every tip carries it, and almost nobody using it can tell you what it actually measures or when it lies. This piece explains what the PE ratio is, how to read it on NEPSE specifically, and, more importantly, the three situations where a PE number will fool you if you take it at face value.
What the PE ratio actually measures
PE stands for price to earnings. You take the market price of one share and divide it by the company’s earnings per share (EPS) over the last year.
PE ratio = share price ÷ earnings per share.
If a stock trades at NPR 400 and earned NPR 20 per share last year, its PE is 20. The plain-English translation is this: you are paying NPR 20 today for every NPR 1 of annual profit the company currently makes. Turn it around, and it is a rough payback period. At a PE of 20, if profits never grew and were all paid out to you, it would take twenty years of earnings to get your money back.
That framing is the useful part. A PE is a price tag on a company’s current profit. A high PE means the market is paying up, usually because it expects earnings to grow. A low PE means the market is paying little, usually because it expects trouble or because the crowd has simply not noticed the stock. The ratio does not tell you which of those it is. That judgment is your job, and getting it wrong is where most of the money is lost.
Before you trust any PE figure, you have to trust the E. On NEPSE, the E is exactly where the number breaks.
The EPS trap: annualized quarterly earnings
Here is the single biggest reason the PE ratio on NEPSE misleads beginners, and it has nothing to do with the price. It is the earnings.
Nepali listed companies report unaudited results every quarter. Most data portals do not wait for the full-year audited profit to compute a PE. They take the latest quarter’s EPS and annualize it, meaning they multiply it up to a full-year figure, so they can show you a “current” number. NEPSE’s own published sector and market PE figures work off reported earnings that are updated as companies file. That sounds harmless. It is not, for two reasons that hit Nepali stocks harder than most.
First, earnings here are lumpy and seasonal. A hydropower company earns most of its money in the wet monsoon months and very little in the dry season. Annualize a strong monsoon quarter and you get a flatteringly low PE that has nothing to do with the full year. Annualize a dry-season quarter and the same stock suddenly looks wildly expensive. Neither number is real. We have written before about how monsoon and the dry season swing hydropower earnings, and the PE ratio inherits every bit of that distortion.
Second, a single unusual quarter warps the whole figure. A bank books a one-time recovery or takes a heavy write-off on bad loans in one quarter, and the annualized EPS lurches. The PE lurches with it. The company has not become cheap or expensive. The math has just been fed a bad input.
So the first discipline is simple. Before you react to any PE, ask what earnings produced it. Is it built on audited annual profit or annualized from one quarter? Is that quarter typical, or was it a monsoon peak, a dry-season trough, or a one-off? If you cannot answer that, you do not actually know the company’s PE. You know a number a website generated.
Why comparing PE across sectors is close to meaningless
The second trap is comparing PE ratios across different kinds of companies as if they were interchangeable. They are not, and on NEPSE the gaps are enormous.
Look at the spread. As NEPSE valuations ran near record highs in late 2025, the overall market PE sat around 38, well above its longer-run average nearer 31, according to figures compiled by ShareSansar from NEPSE data. Within that same market, commercial banks traded at a PE of roughly 16, the lowest of any sector, while microfinance sat far higher, in the mid-40s. Hydropower has historically traded well above the banks too.
Now think about what a naive comparison does with that. A beginner sees a commercial bank at a PE of 16 and a microfinance company at 45 and concludes the bank is “cheaper.” In one narrow arithmetic sense it is. But the two numbers are answering different questions about different businesses.
Banks are mature, heavily capitalized, tightly regulated by Nepal Rastra Bank, and their earnings grow slowly. A market that expects slow growth pays a low multiple. That is rational, not a bargain. Microfinance and many small-cap stocks carry high PEs partly because investors expect faster growth and partly because their small floats let a handful of buyers push prices far above what earnings justify. A high PE there can mean genuine growth, or it can mean a thin, speculative stock that a few players have run up.
The rule that follows is one incumbents rarely spell out. Compare a stock’s PE only against its own sector and its own history, never against the whole market and never against a company in a different business. A commercial bank at a PE of 16 is only cheap or dear relative to other commercial banks and to where that bank has traded in the past. Held up against a microfinance stock at 45, the comparison tells you nothing except that banks and microfinance are different animals. If you want to judge a bank properly, the PE is a starting point, not the analysis; you have to open the numbers, which is why it pays to know how to read a bank’s quarterly report and which banking ratios actually matter.
When a low PE is a value trap
This is the trap that costs the most, so it deserves its own section. A value trap is a stock that looks cheap on its PE but is cheap for a reason, and the reason is that its earnings are about to fall or its business is deteriorating.
The mechanism is easy to miss because it hides inside the math. PE is price divided by earnings. A stock can show a low PE in two very different ways. Either the price has fallen while earnings hold up, which can be a real opportunity, or the earnings are temporarily inflated while the market, seeing what is coming, has already marked the price down. The second case produces a low PE that is a trap.
Picture a bank whose last full year included a large, one-time recovery of a loan everyone had written off. That recovery inflated its profit, so its EPS is unusually high, so its PE looks unusually low. The market knows the recovery will not repeat and prices the stock for next year’s lower, normal earnings. To a screener, the stock looks cheap. To anyone who reads the report, the “cheapness” is an illusion created by a profit that is not coming back.
Or picture a company facing rising bad loans, a squeezed spread, or a sector in decline. Its trailing earnings still look fine, so its trailing PE looks reasonable or low. But the earnings are about to roll over, and the market has started selling ahead of the fall. The low PE is not the market being slow. It is the market being early, and the retail buyer chasing the low number is the last one in.
So how do you avoid the trap? Never buy a low PE on the number alone. Ask why it is low. Is the price depressed on fear the market has overdone, with earnings genuinely stable? That can be an opportunity. Or are the earnings propped up by something temporary or about to decline, so the low PE is really the market telling you the E is going to shrink? That is a trap. The PE cannot tell these apart. Only reading the business can. A low PE is a question, not an answer.
When a high PE is justified, and when it is just a bubble
The reverse mistake matters too, though it costs less often. A high PE is not automatically a reason to avoid a stock, and dismissing every expensive-looking company on its multiple alone will make you miss the best businesses on the board.
A high PE is justified when a company is genuinely growing its earnings fast and can keep doing so. If profits are compounding at a strong clip, paying a higher multiple today can still be sensible, because next year’s earnings shrink the effective PE for you. Growth investors pay up for this on purpose. The catch is that the growth has to be real and durable, not a single good quarter annualized into a story.
A high PE is a bubble when the price has run far ahead of any plausible earnings, usually on momentum, a thin float, or a rumor. Much of the froth in Nepal’s smaller stocks is exactly this. A handful of buyers push a low-liquidity share up, the PE balloons, and the number that gets quoted to justify buying more is the very number that should be warning people off. When an entire market’s PE sits near record highs and well above its own long-run average, as NEPSE’s did in late 2025, the honest reading is not “the market has re-rated.” It is “prices are stretched relative to the profits underneath them, and the margin for disappointment is thin.”
The verdict on high PEs is this. Pay up only for growth you can actually see in the numbers, and treat a high PE with no earnings growth behind it as a speculation, not an investment. The multiple is a claim about the future. Make the company prove the claim.
The other things a PE quietly ignores
Even used carefully, a PE leaves out things that matter on NEPSE, and you should hold them in mind.
It ignores debt. Two companies can show the same PE while one carries heavy borrowing and the other none. The leveraged one is riskier, and the PE says nothing about it.
It ignores bonus shares and capital changes. Nepali companies love issuing bonus shares, which increase the share count and mechanically dilute EPS even when total profit is unchanged. A PE computed before and after a bonus issue is not comparing like with like. Always check whether the EPS reflects the current, post-bonus share count.
It ignores the quality of earnings. A profit built on a sustainable core business is worth more than the same profit flattered by a one-off gain, a revaluation, or an accounting quirk. The PE treats every rupee of reported profit as equal. They are not.
And it says nothing about what you keep after tax. Your PE-based bet only pays off if you sell at a gain, and on that gain you owe capital gains tax, currently 10 percent on shares held under a year and 7.5 percent on shares held longer under the Finance Bill 2083 for the 2026/27 fiscal year, as reported by The Rising Nepal. None of that shows up in the ratio. If you are going to lean on valuation at all, at least know how capital gains tax on NEPSE shares eats into the return the PE implicitly promises.
The verdict: use the PE as a question, never an answer
The PE ratio is worth knowing, and it is worth ignoring in exactly the way most NEPSE investors use it. Used well, it is a fast way to ask whether the price you are paying is reasonable against the profit you are buying and to spot when a whole market or a single sector has drifted far from its own history. Used badly, as a standalone signal that a low number means cheap and a high number means expensive, it will walk you straight into value traps and out of the best-growing companies on the board.
So use it as the opening question, not the closing verdict. When you see a PE, do three things before you act. Check what earnings produced it and whether they are audited, annualized, seasonal, or one-off. Compare it only to the same sector and the stock’s own past, never to the whole market. And when the number looks unusually cheap, assume it is a trap until the business proves otherwise. The PE ratio tells you what the market is paying. It never tells you whether the market is right. That part is on you.
This is analysis, not financial advice.
