I have heard, as a loose rule, assets classes which have low volatility, generally, have low returns.
Good to hold on to close to retirement time.
Conversely asset classes which have higher volatility generally do better over the long term.
(This is assuming a buy and hold strategy)
So if I were to invest a cash gift, on behalf of a preteen child (i.e., 30-50 year outlook), what would be some assets which would go best over that period?
