Investor frameworks
Permanent capital — preservation before performance
A multigenerational frame in which the first objective is never losing capital permanently. It changes what you screen for - resilience, balance-sheet durability and dividend persistence over growth rate.
A different objective function
Most investing frameworks maximise something: return, or return per unit of volatility. This one starts somewhere else. It asks capital to survive across generations, which makes the objective avoiding permanent loss rather than maximising anything.
That is not caution dressed up. It follows from arithmetic. A portfolio down 50% needs 100% to recover; down 80% it needs 400%. Losses and gains are not symmetric, so the compounding of a long-lived pool of capital is dominated by its worst outcomes rather than its best.
Permanent loss is not volatility
The distinction is the whole framework.
Volatility is the price moving. For an investor who does not have to sell, it is mostly noise, and occasionally an opportunity.
Permanent loss is the business being worth less than you paid, forever — the balance sheet failing, the moat eroding, the dilution that follows a rescue financing. No amount of patience recovers it.
A framework built around the second one screens differently. It cares enormously about debt and hardly at all about a drawdown in a sound business.
What it screens for
- Resilience — how the price has behaved through real drawdowns, which is what beta is a rough proxy for
- Balance-sheet durability — net cash rather than net debt, and interest comfortably covered by operating profit
- Dividend persistence and coverage — a payout maintained through a recession is evidence about the business, and coverage is what makes it repeatable
- Price discipline — a free-cash-flow yield that makes sense without needing growth to arrive
Notice what is absent: growth rate, market share, addressable market. Not because they do not matter, but because they are not what determines whether capital survives.
The cost of this frame
It systematically underweights the best-performing assets of most decades. A framework that requires net cash and dividend coverage would have avoided almost every large technology compounder during the period they compounded most.
That is a real cost, and it is accepted deliberately: the frame is designed for capital that must not be lost rather than capital that must grow fastest. Applied to a portfolio with a different purpose, it is not conservative — it is simply the wrong tool, and its patience will look like paralysis.
