Every coin these funds hold was bought at some price. Setting what was paid against what it is worth now gives the position of the whole holder base in the plainest terms available, with no modelling in between.

Where the entry-price view reports a level, this reports an amount. That makes it directly comparable with other sums of money and with very little besides, which is a narrower use than it first appears to be.

What it actually measures

The sign is the reading most of the time. Whether this cohort sits collectively ahead or behind is a straightforward fact about how much pressure the holder base is currently carrying.

The size grows with the complex, so a large figure today and a large figure two years ago are not the same statement about anything at all, however similar the headlines read.

Being underwater is the condition worth watching for. A holder base collectively behind is one in which any redemption crystallises a loss for somebody rather than a gain.

The figure moves without anyone acting. Price alone changes it every day, which is why a large swing here says more about the market than about the funds.

A large gain is a statement about size, not about performance

A figure in the billions reads as success and is mostly a statement about how much money sits in the funds. A complex ten times the size will show a gain ten times as large from an identical move, having done nothing differently.

The percentage version of the same quantity sits on the neighbouring view for precisely this reason. Read together the two answer both questions; read alone, this one flatters scale and quietly mistakes it for skill.

Return on Capital: fresh money changes the number without anything changing

The reading is scale-free, so it can be set against any other asset’s return on identical terms. That is a genuinely rare property among the figures quoted about this market.

A percentage falling looks for all the world like performance deteriorating. Here it happens routinely for an entirely different reason: new money arriving at today’s price pulls the average entry upward and the return downward with it.

That is a mechanical effect rather than a bad sign. Telling it apart from a genuine deterioration means checking whether flows were arriving over the same stretch, which is one view away and worth the detour.

What it does not tell you

It values everything at a single price, so it says nothing at all about the spread of entry points sitting behind the average that produced it.

Unrealised is the operative word. Nothing here has been crystallised, and a position can move from one side of the line to the other without anyone acting.

It reflects the funds’ holdings rather than their investors’. Anyone who bought and sold inside a fund leaves no trace here at all.

It is measured against a cost basis built from reported flows, so every revision to those flows moves this figure too.

How to read it

In profit. The complex is collectively ahead of what it paid.

Underwater. The complex is collectively behind what it paid.

Common questions

What exactly is set against what?

What the funds paid for the coin they hold, against what that same coin is worth now, expressed as an amount of money rather than as a price level.

Why does the size grow over time?

Because the complex grows. A larger set of holdings produces a larger figure from the same move, which is one reason the size is a poor guide to how well anyone has done.

Why does being underwater matter?

Because a holder base collectively behind is one where any redemption crystallises a loss for somebody. It is a different pressure from a base sitting on gains.

Does this show individual investors’ positions?

No. It reflects what the funds hold and what the funds paid, so an investor who bought and sold inside a fund leaves no trace here.

Is anything realised?

Nothing at all. A position can cross from one side of the line to the other with nobody having done a thing, which is worth holding onto before reading any of this as behaviour.

Why express it as a share?

Because doing so removes size from the comparison entirely. A large complex up modestly and a small one up sharply become directly comparable, which the money figure can never make them however it is presented.

Does it say how long the money has been in?

No. It measures profit against capital and not against time, so a quick gain and a slow one of the same size read identically.
