Eight Rules Revisited #5: The rule i got half wrong

This one is different. Of all the rules in the series, Rule 5 is the first where Stuart admits he has genuinely changed his mind, not refined a nuance, but rethought the core idea.

In Investopoly, he taught the textbook approach: blend negatively correlated assets to smooth out portfolio volatility, the classic diversification playbook most investors are told to follow. Eight years and a lot of evidence later, Wealth by Design makes a different case. The real risk controls, he now argues, aren't clever correlations at all—they're quality and price. Own high-quality assets, avoid overpaying, and you've addressed risk at its source rather than papering over it with offsetting volatility.

He reframes the role of defensive assets too. Rather than acting as a permanent volatility damper that quietly drags on long-term returns, they work best as a targeted one-to-three-year spending buffer, enough to ride out a downturn without being forced to sell growth assets at the wrong time. And he explains why long-term returns are far more predictable from starting valuations than most investors appreciate.

An honest, evidence-driven episode about updating your thinking when the data demands it.
