Market History

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.

Why a 10% Average Return Tells You Almost Nothing About Any Single Year

If someone told you that the U.S. stock market has finished a given calendar year higher than it started roughly seventy-three times out of the last ninety-nine, you might reasonably conclude that stocks are a fairly comfortable bet. If someone then told you the long-run average annual return over roughly a century is about 10%, you might imagine a market that quietly compounds wealth every year, like a savings account with slightly better manners. Neither impression survives contact with the actual year-by-year record.

When the Market Looks Expensive: What History Really Says About Long, Flat Decades

Every few years, someone points at market valuations and warns that stocks are too expensive. Prices keep rising anyway. Eventually, the warning starts to sound like background noise — the financial equivalent of a boy crying wolf. The uncomfortable possibility, though, is that a warning can be wrong for years and still turn out to matter, just on a longer clock than anyone wanted to wait for.

When the Biggest Bet Isn’t the Smartest One

A prediction market feels like it should be honest by construction: real money changes hands, so surely only people who actually know something would risk it. That intuition is comforting, and it is also the exact assumption a new study puts under the microscope — with results that should make any investor pause before treating “big money” as a synonym for “good information.”

Two Founders, One Debate: What 250 Years of American Debt Teaches Investors About Risk

Every time a headline warns that the national debt has hit a fresh record, it’s worth remembering that the United States was born broke. In 1776, the newly declared nation had no power to tax, a currency worth little more than the paper it was printed on, and defaulted loans owed to European lenders. That founding fact — often lost in modern debt panic — is the starting point for a more useful investor question than “is this the crisis that finally breaks the system?” The better question is: how has this system historically behaved under stress, and what does that behavior actually tell us about risk today?

Record Margin Debt Isn’t a Crash Signal — It’s a Fragility Gauge

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.

The AI IPO Wave Is Not the Signal — What Comes After Is

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. But for investors trying to make sense of what a concentrated wave of AI mega-IPOs actually means for markets, the debut day excitement is probably the least important part of the story.
