All-weather investing

What all-weather investing is

All-weather investing is a way of building a portfolio so that it can hold up across a range of economic environments, rather than depending on any single one. The starting observation is simple: asset returns are driven mostly by two forces — growth and inflation — and specifically by whether each comes in above or below what markets had already priced. Cross those two forces and you get four regimes: growth rising, growth falling, inflation rising, inflation falling. Most assets are built to win in one of them and to struggle in another.

An all-weather construction holds assets matched to each of those regimes at the same time. In broad terms, equities tend to do well when growth is strong and inflation contained; commodities when growth and inflation rise together; government bonds when growth and inflation fall; and assets such as gold and inflation-linked bonds when inflation runs alongside weak growth. Because no single environment dominates the whole book, the portfolio is designed to be resilient without retreating to cash and without simply playing defence.

Why it matters: prepare rather than predict

The appeal of the approach is what it lets you stop doing. You do not need a confident macro forecast — a correct call on the next recession, the next inflation print, or the next rate decision — for the portfolio to function. As the pioneers of the all-weather approach put it, you do not need to bet on knowing how it will all turn out. You prepare for a range of environments instead of predicting one.

That matters more at some moments than others. When a conventional portfolio is heavily concentrated — when, for example, the bulk of its risk sits in equities at a demanding starting valuation — a single adverse regime can do lasting damage. Balancing across regimes is the structural answer to that fragility: it spreads the dependence on any one outcome, so an environment you did not forecast is less likely to dictate the result.

Balancing risk, not capital

A crucial detail separates a genuine all-weather book from a conventional balanced one. A traditional 60/40 portfolio is balanced by capital, but because equities are far more volatile than high-grade bonds, most of its risk still comes from the equity side — it is closer to an equity bet wearing a diversified costume. All-weather construction instead aims to balance the contribution to risk across its sleeves, so that each economic regime carries a comparable share. We have written more on why this distinction matters in a high yield is not diversification: real diversification is a risk source you do not already own, not simply another asset label.

The same instinct runs through the wider posture we describe in the quiet consensus — that the most respected investors across very different styles are not sharing a forecast but a posture: hold quality, keep diversification genuine, and prepare for the regime to change rather than predict its timing.

How B.U.Y. uses it

All-weather construction is the backbone of our Basic Strategy. The portfolio is built around a regime map of the four growth-and-inflation quadrants and sized so that exposures are balanced by risk across them, with the aim of institutional-grade diversification aligned to the prevailing economic environment. Its valuation-disciplined equity sleeve, Equity Holdings, is one component of that wider balance, not the whole of it.

The 2022 market behaves as a worked example of the principle, using only our already-public NAV series. Over that calendar year a conventional 60/40 reference portfolio fell by roughly 10%, as both equities and bonds dropped together under rising rates, while the Basic Strategy finished the year modestly higher — the regimes that hurt a capital-balanced book were partly offset by exposures built for an inflationary, rising-rate environment. Past performance is not indicative of future results, and any single year is illustration, not proof of a repeatable outcome.

All-weather investing does not try to know which environment is coming. It tries to be ready whichever one does.
