Liquidity as a First-Order Investment Risk in NEPSE

First published 23 Aug 2026 · Last verified 29 Aug 2026

In the hills above the Trishuli valley, a man once inherited two ropani of land from his grandfather. On paper, by the going rate that a neighbour's similar plot had fetched the year before, it was worth twelve lakh rupees. He told people this figure with some pride. Then his son needed money urgently — a hospital bill in Kathmandu, payable in three days. The father went looking for a buyer. There was no buyer. Not at twelve lakh, not at nine lakh, not at six. The only person willing to move that fast was a relative who offered four lakh, take it or leave it, because he knew the family had no other option and no other clock. The land had not become less valuable in any economic sense. What had been exposed, brutally and suddenly, was that the twelve-lakh figure had never really been a price — it was a rumour, an estimate, a story the family told itself because nobody had ever actually tried to sell it fast.

This is the story of liquidity, and it is also, structurally, the story of a very large number of NEPSE portfolios. An investor holds a small hydropower counter, sees it quoted on the app at a certain price, multiplies by the number of shares, and feels rich or feels invested. What that number rarely tells them is: could I actually turn this into cash, in a hurry, without giving away a third of it in the process? Part X of this book examined the psychology of the investor — the biases, the emotional loops, the behavioural traps that distort judgment. Part XI turns to something colder and more mechanical: the structure of the market itself, and the ways that structure can hurt you even when your judgment about value was entirely correct. This chapter, the opening chapter of that part, deals with the most underestimated of those structural risks — liquidity.

Lesson 54.1 — What Liquidity Actually Means

Liquidity, in its plain financial sense, is the ability to convert an asset into cash quickly, at a price close to its last-known or fair value, without that act of selling itself pushing the price down. Notice that this definition has three parts, and all three have to hold for an asset to be called genuinely liquid. Speed — you can sell today, not in three weeks. Price integrity — you get something close to the price you expected, not a fire-sale price. And size — this holds true for the amount you actually want to sell, not just for one or two shares.

Cash itself is the only asset with perfect liquidity — one rupee is always worth one rupee, instantly, to anyone. Everything else sits somewhere on a spectrum below that. A fixed deposit at a commercial bank is highly liquid but not perfectly so — break it early and you lose some interest. A share in a large NEPSE-listed commercial bank, actively traded every session, is close to cash for a retail-sized position — you can usually sell a few hundred or a few thousand shares within minutes at a price within a rupee or two of what you saw on the screen. A plot of land in a district headquarters town is far less liquid — it might take weeks or months to find a serious buyer, and the price you eventually agree on could be materially below your asking price. And a plot of land in a remote village with no road access, like the one in the opening story, may be barely liquid at all — it has value in principle, buyers exist in theory, but converting it to cash on a tight timeline can cost you half its "worth."

The mechanism that produces liquidity — or fails to — is the order book. When you place a sell order on NEPSE through your broker, that order does not simply "happen" at the last traded price. It gets matched against buy orders that other people have already placed and are waiting in the queue, at various price levels. If there is a thick stack of buy orders close to the current price — many buyers, in size, bidding just below the last trade — then your sell order gets matched quickly and at a price close to what you expected. This thick stack is called market depth. If there is only a thin scatter of buy orders, or none at all near the current price, your sell order either sits unfilled, waiting for a buyer who may never show up that day, or it has to "walk down" the order book — accepting progressively lower bids — to get filled at all. That walk down the book is where value quietly evaporates. It is invisible on your portfolio statement, because your portfolio statement uses the last traded price, not the price your order would actually have to accept to execute in size.

This is the single most important mechanical fact in this chapter, and it is worth stating plainly before we go further: the price you see on your trading app is the price at which the last trade happened, usually for a small quantity, sometimes minutes or hours ago. It is not a promise that you can sell your entire position at that price right now. For a handful of NEPSE's largest, most actively traded counters, the gap between the quoted price and the realistically achievable sale price for a normal retail position is small enough to ignore. For a very large number of NEPSE's roughly two hundred and fifty-plus listed companies, that gap can be enormous, and it grows sharply — not gradually, but sharply — once the size of the position you're trying to sell exceeds what the day's normal buyers can absorb.

Lesson 54.2 — NEPSE's Liquidity Pyramid: A Market of Extremes

If you sat down and ranked every counter on the Nepal Stock Exchange by how much of it actually changes hands on a typical day, you would not get a smooth, gently sloping distribution. You would get something closer to a pyramid with an extremely narrow tip and an extremely broad base. A small number of large commercial banks, a handful of the biggest hydropower and life insurance names, and a few large finance and microfinance companies account for a hugely disproportionate share of daily turnover. Beneath them sits a long tail — hundreds of smaller commercial and development banks, mid-tier finance companies, and above all the enormous population of small and mid-sized hydropower and manufacturing counters — where many sessions pass with only a few hundred or a few thousand shares changing hands, sometimes across only two or three actual trades.

Some context on scale helps here. In fiscal year 2025/26, NEPSE's total annual turnover was roughly NPR 1,601.87 billion, averaging about NPR 7.18 billion in trades per day across the entire exchange — itself down sharply, about 22 percent, from the prior year's average of roughly NPR 9.20 billion a day, a reminder that even the aggregate liquidity of the whole market expands and contracts with sentiment. On the day of NEPSE's biggest rallies, single-day turnover has spiked past NPR 16 billion. But that headline number is deeply misleading if you take it as evidence that "the market is liquid," because it is not spread evenly across roughly 250-plus listed companies. A large share of it is concentrated in a small cluster of names — mainly commercial banks and a handful of the biggest hydropower and insurance counters — while hundreds of smaller companies barely register in that total on any given day. Hydropower as a sector alone generated close to 44 percent of total exchange turnover in FY 2025/26, but that aggregate figure hides a sharp internal split: it is driven overwhelmingly by five or six large, well-known hydropower names with genuine trading activity, plus the cumulative churn of speculative day-trading across dozens of smaller counters, while a great many other listed hydropower companies — often with only a few hundred thousand shares in free float — go largely untouched for days at a stretch.

The table below is illustrative rather than a live snapshot of any single trading day — floorsheet activity on NEPSE shifts constantly — but it reflects the general shape of the market that any investor who has watched the floorsheet for more than a few weeks will recognise.

The point of this table is not the exact rupee figures — those will shift with every market cycle — but the order-of-magnitude gap between the tiers. A position that a Tier 1 stock's order book can absorb without a ripple can represent many months' worth of normal trading volume in a Tier 3 stock. If you own NPR 500,000 worth of a large commercial bank, you are, for practical purposes, holding something close to cash with upside. If you own NPR 500,000 worth of a Tier 3 hydropower counter, you may be holding something closer to that remote village land — nominally worth a figure, but genuinely difficult to convert to that figure on your own schedule.

It is worth being precise about why this concentration exists, because it is not an accident or a flaw that will fix itself. Commercial banks and the largest hydropower and insurance names have large numbers of shares outstanding, broad and diversified shareholder bases built up over years of rights issues and bonus shares, institutional participation (mutual funds, insurance companies, and increasingly some foreign and diaspora interest), and consistent analyst and media coverage that keeps a steady stream of buyers and sellers active every single day. Small hydropower and manufacturing counters, by contrast, often have a small public float (a large portion of shares locked up with promoter groups who rarely trade), a narrow, retail-only shareholder base concentrated in the specific district or community connected to the project, and long stretches with no news flow at all to bring in new buyers. These are structural features of the company and its ownership, not temporary conditions of a particular week. A stock that is thin today was very likely thin last year and will very likely be thin next year too, cheap valuation or not.

Lesson 54.3 — Paper Value Versus Realizable Value

Every NEPSE investor is intimately familiar with one number: the current value of their portfolio, calculated by multiplying the last traded price of each holding by the number of shares held, and summing across all holdings. This is mark-to-market value — literally, marking your holdings "to the market," meaning to the latest observed transaction price. It is the number your broker's app shows you, the number that determines your margin position if you are trading on a loan, and the number most investors quote when they tell a friend how their portfolio is doing.

Mark-to-market value has one enormous, unstated assumption baked into it: that the last traded price is a price at which you, the holder, could also transact — and not just for one share, but for your entire position, right now, if you needed to. For Tier 1 stocks with deep order books, that assumption is close enough to true most of the time that it causes little harm. For Tier 3 stocks, that assumption is frequently false, sometimes wildly so.

The number that actually matters when you need cash is realizable value — what you could genuinely collect in hand, after commissions, after the bid-ask spread, and after walking down the order book to fill your full quantity, within whatever time frame you actually have. Realizable value is always less than or equal to mark-to-market value, and for illiquid stocks under time pressure, it can be dramatically less.

Two mechanics widen the gap between paper value and realizable value, and every investor should be able to name both.

The first is the bid-ask spread — the gap between the highest price a buyer is currently willing to pay (the bid) and the lowest price a seller is currently willing to accept (the ask, or offer). For a heavily traded Tier 1 counter, this spread is often just a rupee or two on a share price of several hundred or a few thousand rupees — a rounding error. For a thinly traded Tier 3 counter, the spread can be five, ten, sometimes twenty rupees or more on a similarly priced share, simply because so few people are actively quoting prices on either side that the gap between the nearest willing buyer and the nearest willing seller never gets competed down to a sliver. Every time you buy and later sell such a stock, you cross that spread twice, and it is a real, permanent cost — not a paper cost, not a "maybe" cost.

The second, and the larger effect for anyone holding a meaningful position, is order-book depth, or the lack of it. Picture a simplified order book for a thin counter:

If the last traded price was 500 and you want to sell 3,000 shares, your first 150 shares might fill near 498. To fill the next 300, the price you receive drops to 495. To fill the next 600, it drops to 490. By the time your full 3,000-share order is filled, you have sold well below 500 on average, and roughly a third of your shares went for 465 or worse — nearly 7 percent below where the stock was "quoted" moments before you started selling. This is not a hypothetical mispricing or an unfair broker fee. It is simply what happens when a sell order larger than the available nearby demand meets a market with few active participants. The deeper and more crowded the order book, the smaller this effect; the thinner it is, the larger.

There is a broader, more philosophical point buried in this mechanical discussion, and it deserves to be stated directly: a portfolio's mark-to-market value is a useful accounting fiction, not a guaranteed cash number. It tells you what your holdings were worth to somebody, for some quantity, at some recent moment. It does not tell you what your holdings are worth to you, for your full position, right now. Institutional investors who manage large sums learn this distinction early, often the hard way, because their position sizes are large enough that the gap between the two numbers shows up on every single trade. Retail NEPSE investors, trading in smaller sizes in the more liquid names, can go years without the gap ever mattering — right up until the day it does, usually in a small-cap counter, usually at the worst possible moment.

Lesson 54.4 — The Liquidity Trap: Why Illiquidity Stays Hidden Until You Need It

Here is the cruelest feature of liquidity risk, and the reason this chapter insists on treating it as a first-order risk rather than a footnote: illiquidity is completely invisible under normal, favourable conditions, and it reveals itself only under exactly the conditions where you can least afford the surprise.

Think about why. In a rising market, or in a stock that is rising on its own good news, almost nobody is trying to sell in size. Everybody who holds the stock is happy to hold it, because the price keeps going up and there is no urgent reason to exit. The handful of people who do sell — perhaps to book a profit, perhaps for an unrelated cash need — sell small quantities that the thin order book can easily absorb without any visible strain. The stock's chart looks smooth. Its bid-ask spread looks tight enough. Everything about it, on the surface, resembles a perfectly normal, tradeable stock. This is what we might call the dormant phase of illiquidity: the underlying thinness of the market is real and unchanged, but nothing in the investor's daily experience exposes it, because demand and supply happen to be roughly matched at low volumes.

Now change the conditions. A sector-wide correction hits, or bad news breaks about the specific company, or a margin call forces leveraged holders to raise cash immediately, or simply broad market sentiment sours and everyone who has been quietly uneasy about a position decides, more or less simultaneously, that today is the day to get out. Suddenly the number of people wanting to sell is far larger than the number of people willing to buy at anything near the recent price. The very same order book that absorbed small, occasional sell orders without a ripple during the calm phase is now facing a wave of sell orders it was never built to handle. Prices gap down, not smoothly but in jumps, because there simply isn't a buyer sitting at every price level between where the stock was and where it eventually finds one. This is the revealed phase, and it always arrives at the worst possible time — precisely when the investor most urgently wants or needs to sell, and precisely when everyone else wants to sell too.

This asymmetry — calm and forgiving in good times, brutal and unforgiving in bad times — is precisely why liquidity risk is so easy to dismiss and so dangerous to dismiss. Investors naturally judge risk by recent, lived experience. If a stock has never given them trouble selling a few thousand rupees' worth here and there, they generalise that experience to "this stock is fine to trade," without noticing that they have only ever tested it under the one condition — calm, low-urgency, small-size selling — where illiquidity does not show up. The test that actually matters — can I sell a meaningful position, fast, during a period when many others want the same thing — simply never gets run until circumstances force it. And circumstances that force it tend to be exactly the circumstances — panics, sector shocks, margin-call cascades, personal financial emergencies — in which the cost of failing that test is highest.

There is a useful analogy here to insurance and to fire drills. A building can go decades without a fire, and during those decades, the quality of its fire exits, sprinkler systems, and evacuation routes is completely irrelevant to anyone's day-to-day experience of the building. Nobody who works there for those thirty quiet years learns anything about whether the fire exits actually work. The one moment those systems matter is also the one moment it is far too late to go back and install better ones. Liquidity in a thinly traded NEPSE counter works the same way. The "exits" — the depth of the order book, the number of active buyers — are irrelevant on every calm day, and then suddenly, catastrophically relevant on the one day there is an actual fire.

Lesson 54.5 — The Liquidity Premium NEPSE Often Forgets to Charge

In a fully efficient, textbook capital market, illiquid assets are supposed to trade at a discount to what an otherwise identical, fully liquid asset would fetch — and correspondingly, an investor who buys the illiquid asset is supposed to demand a higher expected return to compensate for the extra risk and inconvenience of being unable to exit easily. This compensation is called the liquidity premium (sometimes described from the other direction as an illiquidity discount). It is a completely standard, well-documented feature of nearly every capital market in the world: private equity investors demand higher expected returns than public equity investors for exactly this reason; small, thinly traded bonds yield more than large, actively traded government bonds of similar credit quality; and small-cap stocks on major global exchanges typically trade at somewhat lower valuation multiples than otherwise comparable large-cap stocks, precisely because the market prices in the extra difficulty of moving size.

On NEPSE, this liquidity premium exists in principle but is frequently mispriced or entirely ignored in practice, for reasons that are worth understanding rather than simply lamenting. A large share of NEPSE's trading volume comes from retail investors who are, quite reasonably, focused overwhelmingly on the questions that dominate financial media, brokerage chat groups, and social media stock discussion: is this stock cheap relative to earnings? Is there a good news story — a new project, a dividend announcement, a bonus share proposal? Is the price chart pointing up? These are legitimate and important questions. But they are almost never accompanied, in ordinary retail conversation, by a parallel question: if I need to sell this in a hurry, six months or two years from now, will there be anyone on the other side of that trade? Because that second question rarely gets asked, it rarely gets priced. A small hydropower counter with a genuinely exciting growth story can trade at the same or even a richer valuation multiple than a much larger, much more liquid commercial bank with a duller but steadier outlook — not because the market has rationally decided the illiquidity risk is worth taking on for free, but because most of the participants setting that price simply never factored illiquidity into their decision at all.

This mispricing cuts in a specific, exploitable-but-dangerous direction. It means that, at any given moment, some of NEPSE's small-cap counters are trading as if they carried no more exit risk than a large commercial bank, when in fact they carry substantially more. An investor who buys such a stock purely on the strength of its valuation story, without separately asking "and what is the liquidity discount I should be demanding here, that the current price is not offering me," is implicitly accepting Tier 3 exit risk while being compensated as though they were holding a Tier 1 asset. That gap between the risk actually being carried and the compensation actually being received is, in a very real sense, uncompensated risk — the worst kind, because there is no expected-return benefit sitting on the other side of it to justify taking it on.

It is worth being fair to the other side of this picture, too. There are moments — usually during periods of broad market euphoria — when small, illiquid counters can actually trade at a liquidity premium in the wrong direction, meaning investors bid them up further precisely because their thinness makes them easier to move sharply on small volumes of buying, which in turn generates the kind of dramatic percentage gains that attract attention and momentum-driven buying. This is, if anything, a more dangerous version of the same mispricing: not merely a failure to charge for illiquidity risk, but an active, if usually unconscious, reward for it — right up until the buying stops and the same thinness that inflated the stock on the way up accelerates its collapse on the way down.

Lesson 54.6 — Circuit Breakers: When the Exit Door Locks Itself

Everything discussed so far in this chapter assumes that, however unfavourable the price, a market for your shares exists at all — that somewhere, at some price, a willing buyer can be found if you are patient or desperate enough. NEPSE has a mechanism, however, that can remove even that assumption for a period of time: the circuit breaker.

A circuit breaker is a rule that automatically halts trading — either in an individual stock or across the entire exchange — once price movement exceeds a defined threshold within a session. The stated purpose is protective: to slow down panic, prevent disorderly price discovery, and give participants a cooling-off period before trading resumes. As of the most recent rule changes, effective from April 2026 under the Securities Trading Operation (Fourth Amendment) Regulations, NEPSE operates a two-layer system.

The mechanism most relevant to this chapter is the individual-scrip daily price band. Once a stock hits its lower limit for the day — a 15 percent fall from the previous close, under the current rule — trading in that specific scrip does not simply become expensive or wide-spread; it can effectively stop. Sell orders can still be placed, but if there are far more shares offered for sale at or below the limit-down price than there are buyers willing to take them, trades simply do not execute in the quantity sellers want, or at all. The stock can sit "locked" at its lower circuit for that entire session — and if the underlying selling pressure has not eased, it can gap down and lock again the next day, and the day after that.

This is the point at which liquidity risk and circuit-breaker mechanics compound into something genuinely dangerous, and it deserves to be stated as plainly as possible: a circuit breaker does not create liquidity risk out of nothing — it takes liquidity risk that was already present in a thinly traded counter and turns it, for a period, into a hard stop. In a Tier 1 stock, the deep pool of buyers usually means the stock rarely even approaches its daily limit except in genuinely extreme, market-wide events, and when it does, the sheer number of active participants means the order backlog tends to clear relatively quickly once trading resumes or the limit resets the next day. In a Tier 3 stock — the exact kind of small hydropower or manufacturing counter this chapter has focused on — a single piece of bad news, or simply a broader risk-off mood among the retail base that dominates its shareholder registry, can be enough to send it straight to its lower limit with a comparatively small number of sell orders, because there was never much buying depth to absorb selling pressure in the first place. Once locked there, with far more shares offered than bid for, the investor who wanted to exit discovers that the market has not merely become expensive to exit — it has become, for practical purposes, temporarily closed to them.

This is precisely why liquidity risk cannot be treated as a purely technical detail to be handled by execution mechanics — a "just use a limit order" problem. It is a risk that changes the character of an investment. A stock that is fundamentally cheap, well-managed, and genuinely undervalued can still impose a real, painful cost on its holder if that holder needs cash during the exact window in which the stock is thinly traded and circuit-locked. The valuation case for owning the stock and the liquidity case for being able to exit it on your own terms are two separate questions, and NEPSE investors — retail and institutional alike — have a strong, understandable tendency to do rigorous work on the first question and almost no work at all on the second. Chapter 58, later in this part, will return to circuit breakers in far greater depth — how they are triggered, how experienced NEPSE participants navigate limit-locked sessions, and what an investor can and cannot do once a position is frozen at the daily band. For now, the essential point is narrower and more urgent: circuit breakers turn ordinary illiquidity into episodic illiquidity's more dangerous cousin — total, if temporary, unavailability of an exit, arriving precisely when the desire to exit is at its peak.
