Risk literacy
Volatility, drawdowns and the different meanings of risk
Risk is not a single number. Different decisions can be exposed to different kinds of uncertainty.
Volatility
Volatility describes how widely prices move over a period. It is useful, but it does not capture every form of financial risk.
Drawdowns
A drawdown measures a decline from a previous peak. Its size and duration can matter differently depending on liquidity needs and time horizon.
Concentration
Narrow exposure can make outcomes more dependent on one sector, issuer, geography or factor.
