Asset allocation by decade: matching risk to the time you have

How the mix between stocks, bonds, cash, and ownership should shift as your earning years shorten and your obligations change.

Allocation is a statement about time. The question is not 'how much risk can I tolerate' in the abstract, but 'how many years until this specific money has a job to do'.

Early years: human capital is your bond allocation

When decades of earnings sit ahead of you, the biggest asset on your balance sheet is your future income. That argues for equity-heavy portfolios and for investing in skills, credentials, and reserves before optimizing fund selection.

Fund the emergency reserve first; it is what keeps you from selling investments in a bad month.
Capture any employer retirement match before taxable investing.
Volatility during accumulation is a feature — you are buying at those prices.

Middle years: obligations arrive faster than income

Housing, children, aging parents, and business ownership stack in the same decade. Allocation decisions here are mostly about liquidity and insurance, not about squeezing out another half point of return.

Money needed within five years generally does not belong in equities.
Term life and disability coverage protect the human capital your plan assumes.
If you own a business, treat it as a large, illiquid, concentrated equity position when measuring your total mix.

Pre-retirement: sequence risk becomes the main threat

A poor market in the first years of withdrawals does far more damage than the same market a decade later, because you are selling into it. Building a few years of stable assets is a defense against that sequence.

A common approach holds two to five years of planned withdrawals in cash and short bonds.
Review Social Security claiming timing and pension elections well before the year you need to decide.
Model withdrawals against realistic taxes, not just gross balances.

Rebalancing keeps the plan honest

Drift is silent. A portfolio set at 70/30 can become 85/15 after a long bull market, leaving you with more risk than you chose.

Rebalance annually or when a band (say five percentage points) is breached.
Prefer rebalancing with new contributions in taxable accounts to limit realized gains.
Document the target so future-you knows what present-you decided and why.
