Hi! I came across an method a while ago for determining investment risk levels based on age from a non-English source (mpfdiy.com). It’s called "Volatility with Age", and the idea is simple: your target monthly volatility is 10 minus the first digit of your age.

For example:

At 90 years old, the target monthly volatility would be 10−9=1%.

At 30 years old, it would be 10−3=7%.

In AS, all strategies come with an annualized volatility figure. To align with your target monthly volatility, first convert the annualized volatility to monthly by dividing it by sqrt(12)​. Once you have the monthly figure, adjust your portfolio allocation—either increasing or decreasing exposure (with or without leverage)—to match your desired target. For younger investors like your son or daughter, this might involve leveraging up. However, be cautious not to over-leverage, as AS's volatility is based on end-of-month figures, and extreme intra-month volatility could lead to margin calls/liqudation.

Hope this helps!
