Investment Readiness — The Five Conditions That Must Come First

The shortcut: "markets go up over time, so the sooner I invest, the better." True on average, and incomplete in a way that hurts real households. Whether you should invest now is not a market question — it's a question about the structure around the portfolio. Five conditions, in order. Skip one and the whole structure is fragile.

1. A funded emergency buffer

Invested money earns long-run returns only if it is never sold at a forced moment. Your buffer — the household-specific months of fixed expenses in accessible cash — is what makes that possible. Investing without one means your portfolio doubles as your emergency fund, and emergencies have a documented habit of coinciding with drawdowns.

2. No expensive debt

Any debt costing more than a realistic long-run investment return is a guaranteed negative-yield asset you already own. Repaying it is a risk-free return no portfolio offers. (Swiss mortgages at low fixed rates are a different calculation — the point is expensive debt: consumer credit, card balances, some vehicle financing.)

3. A recurring surplus

Investing is a flow, not a gesture. A one-off lump sum invested while monthly spending exceeds income is a countdown, not a strategy. Condition three is a positive savings rate you've observed for several months — because it means market falls are met with continued buying rather than a stopped plan.

4. No near-term claim on the money

Money needed within roughly five years — a property deposit, a planned career break, school fees — has a date attached, and equity markets do not respect dates. This is the condition high earners skip most often: investing the deposit "meanwhile," then meeting a 20% drawdown eighteen months before the purchase. Near-term money belongs in cash-like instruments; that's horizon-matching, not cowardice.

5. A written plan you'll hold in a fall

Not a thesis — a paragraph: what you're investing for, the target allocation, the monthly amount, and what you will do when the portfolio is down 25% (the honest answer must be "keep buying" or the allocation is too aggressive). Written before you need it, because deciding during the fall is how returns get destroyed. See our Investment Policy Statement article.

The sequence is the point

The conditions are ordered because each protects the next: the buffer protects the portfolio, the surplus protects the plan, the horizon check protects the goals. Working on condition five while condition one is empty is optimising the roof of a house with no foundation.

And a word for the opposite failure: a household that met all five conditions three years ago and is still "waiting for the right moment" isn't being prudent — it's paying an unpriced cost every year. Readiness is the gate; once through it, delay is the risk.

What are you optimising for?

Control questions: Which of the five conditions does your household meet today — checked, not assumed? Which single condition fails? That one — not the portfolio question — is your actual next action.
