You buy 500 shares of a hydropower company at NPR 400. That is NPR 2 lakh. You tell yourself that if it drops to NPR 360, you are out. Ten percent, no arguments.
Two weeks later it trades at NPR 365. You do not sell, because NPR 360 is not NPR 365. Then the company announces a delay at its project site. The stock opens weak, slides through the session and closes locked at the lower circuit, with sellers queued and almost no buyers. Your NPR 360 exit never happened. Now the question is not whether to take a 10 percent loss. It is whether you can find anyone to take your shares at 25 percent below what you paid.
This is how a stop loss on NEPSE usually fails. Not because investors do not know the rule (everybody knows “cut your losses”), but because the rule as taught assumes a market NEPSE is not. A stop loss is a pre-decided price, or condition, at which you sell a losing position to cap the damage. On deep markets, brokers hold that instruction and fire it automatically. On NEPSE, you are the trigger. A working stop-loss discipline in Nepal has to be built around that fact, and around the thin liquidity and circuit limits that make price stops less reliable here than textbooks suggest.
Why the textbook stop loss breaks on NEPSE

In the textbook version, you place a stop order 8 percent below your purchase price, and if the stock trades there, it converts into a sell order. You do not have to watch the screen or be brave. Three features of NEPSE undermine that picture.
There is no stop order to place
As far as any broker guide or market outlet describes it, NEPSE’s Trade Management System (TMS), the browser platform every broker uses, takes ordinary buy and sell orders. It does not offer a conditional stop order that sits dormant and fires when a trigger price is hit. Regular orders also lapse at the end of the day if they do not fill. So a “stop loss” on NEPSE is a rule in your head, a note on your phone, or a price alert on an app. The execution is manual. If you are in a meeting, on a flight, or simply unwilling to click sell, it does not happen.
That sounds like a technical gap. It is really a behavioral one. An automatic stop removes your judgment at the moment your judgment is worst. Without it, every stop is a decision you make again under pressure, and most people, faced with a red screen, decide to wait.
The circuit limit can skip right over your price
Since April 20, 2026, individual NEPSE stocks can move up to 15 percent in a session, up from 10 percent, under the Securities Trading Operation (Fourth Amendment) Regulations, according to ShareSansar’s report on the change. The pre-open band widened from 2 percent to 5 percent at the same time.
If a stock is falling hard and there are no buyers at your stop price, your sell order joins a queue and waits. If it closes locked at the lower circuit, you may not get out at all that day. Three consecutive lower-circuit sessions at 15 percent leave a stock at roughly 61 percent of its starting price (0.85 × 0.85 × 0.85). A stop you planned at minus 10 percent can, in the worst cases, turn into a forced exit at minus 30 or 40.
A circuit is a speed limit, not a floor. It slows the fall. It does not guarantee you a seat on the way down.
You cannot sell what has not arrived
NEPSE runs a T+2 settlement cycle: shares you buy land in your demat account two working days after the trade. Until they arrive, you cannot sell them. Intraday trading, where you buy and sell the same stock in the same session, is one of the reforms in SEBON’s 10-year capital market plan, but it is planned, not live.
So if a new purchase falls sharply on day one or day two, your stop is irrelevant. Size positions as if the first two days carry no exit, because they do not.
What a stop loss is actually for

Before the mechanics, it helps to be clear about the job.
A stop loss is not a prediction that the stock will keep falling. Plenty of stocks you sell at a stop will recover, sometimes the next week. That is the price of the insurance, and it is why people abandon the rule after one or two “wrong” exits.
What a stop does is cap the size of any single mistake. Losses and recoveries are not symmetric. A 10 percent loss needs an 11 percent gain to recover. A 25 percent loss needs 33 percent. A 50 percent loss needs 100 percent. Our piece on why most retail investors lose money on NEPSE makes the broader case: the damage rarely comes from being wrong once. It comes from staying wrong too long with too much money.
A stop also forces you to write down, before you buy, what would prove you wrong. If you cannot say what would make you sell, you have not made an investment decision. You have made a hope.
Three kinds of stop, and which ones work here
Price is only one way to define an exit. On a market as thin and jumpy as NEPSE, the other two are often more useful.
The price stop
This is the classic version: sell if the price falls a set percentage below your entry, or below a level that matters to you. It works best on liquid stocks, the large commercial banks and the most heavily traded names, where your sell order will almost always find a buyer near your price.
The common mistake is setting it too tight. If a stock routinely moves 3 to 4 percent in a normal session, a 5 percent stop will throw you out on noise. A reasonable rule of thumb (opinion, not regulation) is to see how far the stock typically moves over a few weeks without news, and put your stop beyond that range. For a sleepy large bank that might be 7 to 8 percent. For a volatile hydropower or microfinance stock it might need to be 12 to 15 percent, at which point the stop only makes sense if the position is small.
The thesis stop
Here you exit because the reason you bought is no longer true. You bought a hydropower company because its project was due to start commercial operation this fiscal year, and the company announces a one-year delay. You bought a bank for its dividend record, and it skips the dividend while its quarterly report shows bad loans climbing. The price may not have moved much yet. That is the point. A thesis stop gets you out on the news, before you start inventing new reasons to hold.
For long-term investors, this is the stop that matters most. A holder of a quality bank should not be shaken out by a 10 percent market-wide dip, but should sell without hesitation when the facts behind the purchase break.
The time stop
The least used and one of the most practical. If a trade has not done what you expected within a set period, say three months, you exit regardless of price. “Dead” positions on NEPSE have a way of becoming permanent residents of a portfolio.
Our view is that most NEPSE investors should use a combination: a thesis stop for every position, a price stop for anything held as a trade rather than a long-term holding, and a time stop for speculative buys. A price stop alone, on an illiquid stock, is the weakest of the three.
How to set a stop loss on NEPSE you will actually follow
The hard part is not choosing the number. It is honoring it. These are the steps that make that more likely.
1. Decide the exit before you buy
Write the stop down when you place the buy order, while you are calm. A phone note is enough: “Bought 500 at NPR 400. Price stop NPR 360. Thesis stop: COD delayed past Asar. Time stop: review on February 15.” Once the stock is falling, you will not set a rational stop. You will set a hopeful one.
2. Let the stop set the position size
This is the step that ties stops to everything else. Decide how much of your total portfolio you are willing to lose on any one idea. Many disciplined traders use something in the range of 1 to 2 percent. That is a convention, not a rule, and you can pick your own number. Then size the position so that hitting your stop costs exactly that much.
A worked example. Your NEPSE portfolio is NPR 10 lakh and you are willing to lose 1.5 percent, or NPR 15,000, on any single position. If your stop is 12 percent below entry, the maximum position is NPR 15,000 divided by 0.12, which is NPR 1.25 lakh. If the stock is calmer and an 8 percent stop is reasonable, you can hold up to NPR 1.875 lakh.
Notice what this does. Volatile, illiquid stocks automatically get smaller positions, because their stops have to be wider. And if a circuit lock blows through your stop and doubles your planned loss, NPR 15,000 becomes NPR 30,000: painful, but survivable. The same event on a NPR 6 lakh position is not.
On NEPSE, position size is the stop that cannot fail. It is the only protection that works even when the market will not let you sell.
3. Set alerts, and check them at a fixed time
Since TMS will not watch the price for you, something else has to. Use a price alert on whichever market app you rely on, and check open positions against your written stops at one or two fixed times in the session, so the decision is already made when you see the number.
4. Use AMO to act on a decision made at night
Since August 2026, TMS has accepted After Market Orders (AMO), according to ShareSansar’s report on the launch. You can enter a buy or sell outside trading hours, at a price within 15 percent of the previous day’s close. The order is valid for one trading day and is canceled if it does not execute. ShareSansar also reports that orders within 3 percent of the next morning’s opening price are forwarded into the market.
AMO is not a stop order. It does not wait for a trigger. It is a sell order that goes live the next morning. That makes it a good tool for a decision you have already made: a closing price or an evening disclosure breaches your rule, and you queue the sale near the expected open instead of negotiating with yourself at 11 am. Set the limit too far from where the stock actually opens and the order may not be forwarded, so treat it as “sell at the open,” not “sell if.”
5. Sell with a limit order a little below the market
When the stop is hit during the session, sell with a limit order priced slightly below the best bid rather than a market order into a thin queue (our guide to placing orders on TMS explains why). Then complete the EDIS (Electronic Delivery Instruction Slip) authorization in Meroshare, or the sale does not settle.
6. Never move the stop down
You can raise a stop as a stock rises, for example to your entry price once a position is comfortably in profit. You cannot lower it because you “feel” a bounce coming. A stop that moves down is not a stop. It is a delay.
The averaging-down trap

The most common way NEPSE investors defeat their own stops is by buying more. The stock falls to the stop, and instead of selling, they buy again “to bring the average down.” Now the position is bigger, the stop has disappeared, and the next leg down does twice the damage.
Averaging down can make sense for a sound company you would buy fresh at today’s price, inside a position size planned in advance (we cover when in our piece on averaging down on NEPSE). But if you are averaging down on a stock that has already hit your stop, you are not averaging. You are refusing to accept the loss.
What a stop actually costs you

Every exit has a price. Know it, so it does not become another excuse. Take the opening example. You bought NPR 2 lakh of stock and sell at the NPR 360 stop for NPR 1.8 lakh. Based on one SEBON-licensed broker’s published schedule, brokerage on trades between NPR 50,001 and NPR 5 lakh is 0.33 percent, the SEBON regulatory fee is 0.015 percent, and the DP (depository participant) charge is NPR 25 per stock per day. On the buy and the sell together, that comes to roughly NPR 1,400, or about 0.7 percent of the original position. Your total loss is about NPR 21,400, not NPR 20,000.
There is no capital gains tax on a losing sale, because there is no gain. (On a profitable short-term exit, individuals currently pay 5 percent on the gain for shares held 365 days or less, under the Ministry of Finance notice reported by ShareSansar on September 22, 2026.)
Now compare the alternative. If the stock goes on to lose 30 percent and you finally sell there, your loss is NPR 60,000 plus fees. The stop’s cost is real. It is also the cheapest outcome on the table. A few false alarms a year cost a few thousand rupees. One unmanaged collapse can cost you years.
When not to use a tight price stop
There are cases where a tight price stop does more harm than good. If you buy a large, liquid bank or an established utility to hold for its dividends over five or ten years, a 10 percent price stop will repeatedly sell you out of good holdings in ordinary corrections. Quality stocks fall with the index in a NEPSE bear phase. For that kind of holding, rely on a thesis stop and on position size. Sell when the business deteriorates, not when the market sneezes.
The same applies if you cannot check prices during the session at all. A price stop you cannot execute is worse than none, because it gives false comfort. Size small, review in the evening, and use AMO to act on what you decide.
The investors who most need hard price stops are the ones who trade on momentum, tips or chart patterns and expect to sell within weeks. For them the stop is not optional.
The verdict
A stop loss on NEPSE is less a feature of the platform than a habit of the investor. TMS will not hold the order for you, the circuit limit can skip over your price, and new purchases come with two days of no exit at all. None of that makes stops useless. It changes how you build them.
Decide your exit before you buy. Define it by thesis and time as well as price. Size every position so that hitting the stop, or even doubling through it in a circuit lock, costs a survivable slice of your portfolio. Use AMO and limit orders to execute decisions already made. And never move a stop down.
Most NEPSE investors who lose heavily did not lack information. They lacked a rule agreed before the price started falling. Write yours down tonight, for every position you hold. If you cannot say what would make you sell, that is the stock to look at first.

Frequently Asked Questions
1. What is a stop loss in the share market?
A stop loss is a plan to sell your shares when their price falls to a certain level to limit how much money you lose.
2. Does NEPSE have an automatic stop-loss feature?
No. According to the article, NEPSE’s TMS does not offer automatic stop-loss orders. Investors must monitor share prices and place sell orders themselves.
3. Why might I be unable to sell shares at my stop-loss price?
If a share price falls sharply and there are no buyers, your shares may remain unsold. This can happen when a stock hits the lower circuit limit.
4. What are the three types of stop loss?
- Price stop: Sell when the share price reaches a chosen level.
- Thesis stop: Sell when the reason for buying the shares is no longer valid.
- Time stop: Sell when the investment does not perform as expected within a set period.
5. How much money should I risk on one share investment?
Some disciplined traders risk around 1–2% of their total portfolio on a single investment. This is a guideline, not a fixed rule. Your investment amount should match the loss you can afford.
6. Should I buy more shares when their price falls?
Not automatically. Buying more shares can increase your losses if the company continues performing poorly. Consider buying more only when the company’s condition remains sound and the investment fits your risk plan.
