Volatility, Explained

How mixing different investments changes the size of the swings.

Volatility is the size of an investment's typical ups and downs — not which direction it goes. Because different investments don't all move together, a mix usually swings less than its pieces suggest. That gap is the diversification benefit.

The interactive version lets you build a mix of stocks, bonds, commodities, alternatives, and cash, then shows the mix's assumed average year, its volatility, the diversification benefit, what a typical year looks like, the odds of a down year, and what the swings cost in compounded growth — with the correlation between each pair of asset classes in plain English, and, on a hypothetical portfolio value you enter, what one year of those swings looks like in dollars. The return figures are the same long-term planning assumptions behind the full platform: assumptions, not forecasts. Diversification does not ensure a profit or protect against loss.
