Educational reviews of historical market scenarios, crises, bubbles, recoveries, and long periods of weak returns. History is used as a source of context, not as a reliable forecast of the future.
Every few months a headline arrives warning that stock-market borrowing has hit a new record, and every few months investors ask the same question: does this mean a crash is coming? The honest answer is less satisfying than the headline. Record leverage tells you a great deal about how exposed individual portfolios have become to a downturn — and almost nothing about when, or whether, that downturn will arrive.
A string of trillion-dollar listings would be a spectacle by any measure. SpaceX, Anthropic, OpenAI — the names alone carry enough narrative weight to dominate financial headlines for months.

Every few years, a wave of credible, well-credentialed voices warns that markets have gone too far. They marshal data, draw historical parallels, and raise legitimate concerns about concentration, valuation, and speculative excess.

Yet the uncomfortable truth that rarely makes headlines is this: even a correct bubble call is almost never sufficient to make you money, or to protect you at the right moment.
