Drukenmiller recounts buying $6 billion in tech stocks near the dot-com peak and losing $3 billion in six weeks.
Drukenmiller recounts buying $6 billion in tech stocks near the dot-com peak and losing $3 billion in six weeks.

Those who have done our Well 2 course will recognise this story. This is Stanley Drukenmiller, one of the world's greatest investors. Groupthink can be so powerful that even the best get caught in the fever. As Robert Shiller said, it spreads like a virus. It is contagious.

The most famous contrarian who can resist is Warren Buffett. But even Munger admitted that years before the GFC they bought into a "great" office furniture company, only to realise too late that the great numbers were partly a product of the property bubble bleeding into commercial real estate.

We appreciate valuation as a simple but effective tool. As Buffett says: price is what you pay, value is what you get.

Don't get sucked into the orbit of those who have already benefitted from being early participants, whether by luck or skill, in a boom or bubble.

This week's themes span global trade fragmentation, Australian property, defence spending, the compounding framework, and the commodities story unfolding around the Strait of Hormuz.

Geopolitics

Joan Robinson's 1937 prediction is playing out in real time. Beijing has introduced sweeping new regulations targeting foreign companies that move supply chains away from Chinese suppliers. Trade wars are moving beyond reversibility.

The Oz Economy

Auction clearance rates are at their lowest since 2018. WA just introduced a 2% deposit scheme for homes up to $860,000. And a 3-bedroom house in Rosebery sold for $3.63 million at 90% LVR. We are supposed to believe this is not a bubble.

Special Topics: Don't Lose Money + Commodities

Two extended pieces this week. A framework for thinking about compounding properly using CAPE across market cycles, and the sulfur story: why the Hormuz disruption is not just an oil crisis, but a chokepoint for copper, semiconductors, and defence production.
