What should the split aim for?

Best return per unit of risk Leans towards whatever paid best for the risk it carried.

The lowest possible risk The calmest mix. It only needs how much each holding moves and how they move together.

Least risk for a target return Name a yearly return and see the least risky way to have reached it. Left empty, it uses the return of splitting equally. Return a year

Equal weight Estimates nothing. The yardstick the others are judged against.
