Capital Allocation in Uncertain Markets

Uncertainty is not a regime; it is the default condition of capital allocation. To organise a firm around the assumption that uncertainty will eventually clear — that the next quarter, or the next year, will reveal the answer — is to construct an institution that is consistently and predictably surprised.

We are writing this letter against a market backdrop whose principal characteristic is not the direction of any single variable but the breadth of plausible outcomes across several. Interest rates may compress, hold, or rise. Inflation, having moderated, may stabilise or accelerate in a second wave. Geopolitical configurations that appeared settled two decades ago are in flux. We do not propose to forecast the resolution of any of these. We propose, instead, to describe how a firm ought to be operated when the dispersion of plausible outcomes is unusually wide.

“Allocation discipline matters most when the temptation to abandon it is highest.”

The first principle is the most uncomfortable to articulate. Allocation discipline matters most when the temptation to abandon it is highest. In benign environments, almost any reasonably constructed thesis works. In conditions of dispersion, the cost of an undisciplined commitment compounds quickly, and the cost of a disciplined absence — the foregone return on the transaction not done — is comparatively cheap.

We hold three convictions about allocation in conditions like the present.

(One) Optionality has a price, and the price is worth paying. Holding capital available, against the temptation to deploy it on a calendar, is itself a position. The institutions that will look strongest in 2030 are not those that deployed most aggressively into the present uncertainty; they are those that retained the capacity to deploy materially into whatever clarity emerges. This is a position we have held, and continue to hold, with conviction.

(Two) Diversification across thesis architecture, not across asset count. The mistaken form of diversification — owning many things that share an underlying exposure — is the principal source of portfolio fragility in conditions of dispersion. We are more concerned with whether our investments share a common assumption about interest rates, sovereign posture, or sector cycle than with whether they share a common label. Two industrial businesses with similar economics are less concentrated, in our view, than two superficially different businesses that both depend on cheap capital and orderly markets.

(Three) The institution itself is part of the allocation. The capital structure, the governance posture, and the cultural composition of an investment firm are themselves bets — on the future that the firm will be operating into. A firm that is staffed and structured for a benign decade is, in conditions of dispersion, mis-positioned regardless of the quality of its individual investments.

A practical observation about pace. In our experience, the temptation in uncertain conditions is to accelerate. The reasoning is that uncertainty is temporary; one must move while the window is open. We hold the opposite posture. Uncertainty is the condition under which a disciplined firm earns the relative outperformance that compounds over decades. Acceleration, in conditions of dispersion, is more often a confession of impatience than an expression of conviction.

“Patience is not paralysis.”

There is, however, a careful distinction to be drawn here. Patience is not paralysis. The firms that look strongest in 2030 will be those that were able to act decisively, in size, when the right opportunity emerged — and the ability to act decisively in size is itself a function of the discipline maintained in the intervening period. The two postures are not opposed. They are sequential.

A second observation, about narrative. In conditions of dispersion, the institutions that suffer most are those that have committed publicly to a particular forecast. The reputational cost of being wrong about a single variable is small; the structural cost of having organised a firm around a wrong forecast is large. We do not publish forecasts. We do not orient the firm around them. We orient the firm around the conditions of plausibility and around the postures that perform across a range of them.

A closing point. The most useful question, in conditions like the present, is not what is going to happen. It is: what would I do, with what capital, under each of the plausible outcomes. If the answer is the same across most of them, the position is robust. If it varies materially, the position is fragile, regardless of how compelling the central case appears.

We construct positions to be robust across the range of plausible 2030s. We hold them with the patience required to allow the resolution of that range to occur. We will not always be early. We do not need to be.

We need only, in the long counting, to have been correct.
