Volatility Is the Admission Price, Not the Risk

The uncomfortable truth is that my instincts cannot tell a falling share price from actual danger. The job is to build a portfolio and a mind that can tell the difference.

Chain Bridge and the Hungarian Parliament, Budapest. April 2025.

In April 2025, I was in Budapest, meant to be on holiday, and instead spent an indecent amount of time staring at falling prices on my screen. I felt the drawdown in the only way that matters: as real money, in my own account, disappearing by six figures while every instinct in my body suggested that doing something, anything, would feel better.

Budapest is a beautiful city, which is not especially helpful when tariffs hit. More important than the trades I did or did not make was the thing going on in my own head: I felt fear, I felt regret, and I felt the very human urge to convert uncertainty into certainty, even at a bad price.

The problem is that my instincts do not distinguish particularly well between actual danger and falling share prices. Falling share prices are not automatically danger. They are information, and the job is to work out what kind. The market was not telling me my thesis was wrong. It was telling me sentiment had turned.

I did not sell, though, and the reason was not that I am some sort of monk in a linen shirt who has transcended loss aversion. I am not. The reason was simpler and less glamorous: I knew what I owned, I knew why I owned it, and I knew what I thought it was worth.

What is volatility, and what is it not?

Howard Marks made the distinction plainly in “Risk Revisited Again“: what investors actually fear is not price movement but the possibility of permanent loss. Volatility became the academic proxy because it was quantifiable, but it was always the wrong measure.

I agree with Marks — but I want to take the distinction one step further, because in my own portfolio the useful question is not what volatility is but when it becomes dangerous. The answer, as far as I can tell, is: through only two mechanisms. Either my structure forces me to sell, or my psychology does. Permanent loss itself is narrower than most drawdowns suggest — fraud, obsolescence, terminal competitive decline, or regulatory destruction. Four ways a business becomes permanently worth less. If none of them is in play, the price is moving without the business moving, and moving prices are noise, however unpleasant.

The first mechanism is structural. This is where a lot of institutional pain comes from, and it is also why private capital with the right design has a real edge. If you are running leverage, a drawdown can become a margin call. If you are managing outside money, a drawdown can become a redemption. If you are judged quarterly on relative performance, a temporary decline can become a career problem long before it becomes an investment problem. Time horizon is not a decorative preference in investing. It is often the whole game.

That is why my own portfolio is built to eliminate forced selling. My living expenses are covered by income-generating assets. I do not use leverage. I do not manage external capital. That removes the first channel almost entirely.

The second mechanism is psychological, and this is the harder one because it follows you around. You can design away leverage. You cannot design away being human. If I sell simply because I cannot bear the discomfort of seeing prices down another 10%, even though my underlying thesis is intact, then I have voluntarily converted volatility into permanent loss. Nobody forced me. I did it to myself.

Part of what makes the psychological channel so difficult is that the fear feels rational. A falling price appears to carry information — the market is selling, so it must know something you do not. That instinct is not stupidity; it is pattern recognition misfiring. Price movement is not the same as informational superiority. When the market sells, it tells you about the constraints of the people selling — not about the business.

What actually constitutes permanent loss?

In my experience, most drawdowns have the same basic explanation: the market is selling off for reasons that are only loosely connected to the underlying business. I don’t buy stocks — I buy tiny pieces of what I believe to be great companies, at prices below my estimate of intrinsic value. When prices fall but the business hasn’t changed, that’s not a warning. That’s a price decline worth sitting through, not running from.

When a position I own is in a genuine drawdown, I run four questions before I touch anything. Has management integrity changed — because I have been wrong about management before, and it is usually the first thing I am too optimistic about. Has the industry structure worsened, not cyclically, but in a way that permanently favours someone else. Has regulation impaired the model — not inconvenienced it, impaired it. Has the balance sheet become a real problem, or am I just watching a line item worry me. If none of the four has shifted, I am almost certainly looking at volatility, not impairment.

Why does homework create holding power?

Deep research creates holding power because conviction anchored in business reality can survive a falling share price, whereas conviction anchored in price action cannot. If I understand the industry, the competitive position, and a sensible fair value range, then a drawdown changes my emotional state, not my estimate of intrinsic value.

This is the bit that gets romanticised in investing books and then brutalised by actual markets. People say “just hold through volatility” as if that was a personality trait. Like being tall. It is not.

Holding power is downstream of preparation.

If I have done the work properly, a 30% decline tells me the market’s mood has changed. It does not automatically tell me the business has deteriorated by 30%. Those are wildly different statements, but markets present them in the same font, which is unhelpful. The screen says the bid is lower. Fine. The screen does not tell me whether the bid is rational.

That, to me, is the real reason most investors cannot hold through a continued decline: they do not truly understand what they own. If your conviction is anchored in price action, a further decline dissolves it. If it is anchored in the business, the decline is just the price changing, which is a different thing entirely.

I should be honest about the obvious objection: the diagnostic is only as good as the analyst running it. If I have spent months building a thesis, I am not a neutral examiner of the evidence — I am a motivated one. The risk is not that I ignore the checklist but that confirmation bias shapes what I see when I run it. I do not have a risk committee to overrule me. What I have is the discipline to name, in advance, the specific evidence that would change my mind — and to write it down before the drawdown arrives, when my judgement is not yet compromised by the desire to be right. It is not a guarantee against self-deception, but it is the best structural defence I have found so far.

The time to do the work is in calm weather — deciding what I want to own, at what price, in what size. A GTC limit order is exactly that: a standing instruction placed before the storm that fires automatically when the price arrives, without requiring my emotional state at 3am to agree. When the sell-off arrives, the calm-weather version of you is already at the desk.

Familiarity, Not Heroics

Budapest tested whether that preparation held. The episode mattered because I did not just endure it; I used it as deliberate psychological training. The useful skill in a sell-off is not emotional numbness but the ability to observe fear, regret, and the urge to act without automatically obeying them.

The Budapest drawdown felt awful. I did not enjoy it. I was not floating above it in enlightened detachment, whispering about intrinsic value while the minibar mocked me from across the room.

What I did differently was pay attention. Most investors respond to a sell-off in one of two ways. They either stop looking entirely, or they stare at the screen in a state of rising panic and let each downtick rewrite their beliefs. I tried to do neither.

I watched the losses accumulate. I named what I was feeling: fear, regret, frustration, the desire for relief. And then I separated those feelings from the actual state of the businesses I owned. That gap — between what I felt and what I knew — was the whole exercise. My feelings were screaming catastrophe. My research was saying, in effect, “the market is upset; the businesses are still the businesses.”

Budapest was not my first sell-off. The first time a position of mine dropped 30% I spent three weeks second-guessing every decision that led to the buy. By Budapest I spent a lot less time doing that. The gap is not willpower. It is evidence. My subconscious has seen enough of these chapters to know how they usually end.

I want to be honest about this: it is genuinely difficult. Anyone who tells you they feel nothing when watching large drawdowns accumulate on real money — not paper money, not a simulation, and with no salary arriving at the end of the month to soften the edges — is either exaggerating or has not yet been tested with enough capital at stake. The goal is not to feel nothing. The goal is to feel it, understand it, and choose not to act on it. That, to me, is the real edge of lived experience.

Not heroics. Familiarity. The first major drawdown feels like an emergency. By the fifth, it starts to feel more like weather.

Where I Paid the Admission Price Most Recently

China equities are where the admission price is highest — and where confusing it with risk is most expensive. Sentiment swings are amplified by policy headlines, geopolitical friction, and Western media narratives that default to catastrophe. If you conflate that volatility with risk, you will never hold through the drawdowns that create the best entry points.

In April 2026, when the Iran headlines hit and the Hang Seng sold off, I noticed the familiar sequence almost immediately. The screen made everything feel more urgent than the facts justified. The impulse was the same as in Budapest: do something, reduce the discomfort, convert uncertainty into action.

So I ran the checklist before I let myself touch the order ticket. Had anything changed about the businesses I was watching? Had the competitive position worsened? Had the policy structure shifted? The answers were no, no, and no. What had changed was sentiment.

That distinction matters because the psychological danger in a sell-off is not fear by itself. It is fear smuggling itself into the analysis and pretending to be new information. Once I could see that happening, the job was simple, if not pleasant: slow down, go back to the work, and act only if the gap between price and value had genuinely widened.

That was the setup with Kingdee. I had done the homework months earlier, when I traced how Beijing’s binding factory-automation KPIs were creating a mandate-backed upgrade cycle for enterprise software. The thesis was ready. The fair value range was set. When the Iran sell-off pushed the price into that range, I bought. Same with Hesai — the production wins were already in the work, the certification path was already in the work, and the question in front of me was not whether the headlines felt alarming but whether the business had changed. It had not.

The important part, though, is not that I bought them. It is that the decision did not come from adrenaline. It came from homework done in calm weather, checked again under pressure, and executed only after I had separated what I felt from what I knew. That is the admission price in practice.

If you’re new to Cohong Lane, that is the whole point of the publication: I invest my own capital from Hong Kong and publish the process, the pressure, and the mistakes in public so readers can inspect the reasoning, not just the conclusion.

I have sat through drawdowns that lasted quarters, not days — the 2022 China panic ground on for quarters while every Western headline declared the market uninvestable. I ran the same diagnostic then. I held. The framework held.

Volatility is the admission price. Risk is what happens if I have built a portfolio, or a mind, that cannot afford to pay it.
