Diversification

Spreading money across assets so no single failure ruins you.

Diversification lowers the damage any one holding can do. It cannot lower risk that affects everything at once, which is why "diversified" portfolios still fall in a general crash.

There is a tension worth naming: concentration builds fortunes and diversification preserves them. Most people who become wealthy did so concentrated - in one business - and then diversified hard afterwards.
