Reading the Aschenbrenner liquidation.

I went deep on this in a video: how fund blowups actually happen, and which categories of stock stand to gain and lose once the selling stops. The episode has moved on. The mechanics have not.

Why bother with an old liquidation

The specific situation is out of date now, and I would rather say so at the top than have you discover it at minute four. What holds up is everything around it. A liquidation is one of the few moments when a fund's actual structure becomes visible from the outside — and structure is the thing that is otherwise hidden behind a tear sheet and a good letter.

So treat it as a dissection rather than a news story. The patient has been buried. The anatomy is still the anatomy.

Blowups are almost never about being wrong

This is the part that surprises people. Funds rarely die because the thesis was mistaken. They die because the position was too large for the balance sheet to survive being temporarily wrong, and because the moment that becomes obvious is exactly the moment everyone else has decided the same thing.

The sequence is remarkably consistent:

  • Concentration. Conviction and concentration are the same behaviour described by whichever word suits the outcome.
  • Leverage, often invisible. Not always borrowed cash — frequently it arrives as derivatives, financing arrangements, or simply positions whose real size only appears when they move.
  • Correlation nobody modelled. Holdings that looked like different bets turn out to have been one bet wearing several costumes.
  • A demand for liquidity. A margin call, a redemption, a counterparty getting nervous. It does not need to be large; it needs to be immediate.
  • Forced selling. And here is the cruelty: you cannot sell what is illiquid, so you sell what is liquid. Funds do not liquidate their worst positions first. They liquidate their most sellable ones.

A forced seller is not choosing what to sell. That single fact explains most of what looks irrational in the tape during a liquidation.

Which is why the damage lands where it does

Once you accept that a liquidating fund sells what it can rather than what it should, the pattern of winners and losers stops looking random.

The names that get hit hardest are frequently the crowded ones — high quality, widely held, easy to exit. They fall not because anything changed about the business but because they were the fastest source of cash for someone who needed it that afternoon. That is a mispricing with a known expiry date, which is a rare and interesting thing.

Meanwhile the genuinely impaired positions often barely move, because there is no bid to move them. Illiquidity looks like stability right up until it does not.

What I actually take from it

  • Separate the fall from the cause. When a category drops hard and together, ask whether anything was learned about those businesses or whether somebody simply needed money.
  • Watch the plumbing, not the narrative. Financing terms, counterparty exposure and redemption windows tell you more about fragility than any investor letter will.
  • Size is a risk parameter, not a conviction score. The entire genre of blowup is a position that was correct and too large at the same time.

That last one is why I keep returning to position sizing in my own work. Being right is the easy half. Being right at a size you can hold through the part where you look wrong is the whole game.
