Volatility is often used as a proxy for risk, but they aren't the same. A quiet stock that quietly goes to zero has low volatility; a great long-term investment can have very high volatility on the way up.
Long time horizons soak up volatility — decades of 30% down years and 40% up years still average out to strong compound returns for broad diversified portfolios.
