What risk really means

7 min read

In finance, risk is often defined as volatility, how much returns swing. For a real investor it is more useful to ask two questions: could I lose money permanently, and could I be forced to sell at a bad moment?

Volatility versus permanent loss

  • Volatility: prices fall and recover. If you can wait, it is uncomfortable but temporary.
  • Permanent loss: a business fails, or you sell after a fall. The loss is then locked in.

Three kinds of risk capacity

  • Ability: how much loss you can absorb given your income, savings and obligations.
  • Need: the return you require to reach your goals. A bigger goal may force bigger risks.
  • Willingness: how you actually feel and behave when a portfolio falls 25%.

The honest allocation sits at the lowest of the three. High willingness does not help if you will need the money in two years.

Risks beyond the market

  • Inflation risk: money that does not grow loses purchasing power.
  • Concentration risk: too much in one stock, sector or fund.
  • Liquidity risk: not being able to sell when you need to.
  • Behaviour risk: the damage we do to ourselves by reacting to fear and excitement.

Key takeaways

  • Distinguish temporary volatility from permanent loss.
  • Match risk to your ability, need and willingness, and take the lowest.
  • Behaviour is a risk too.
