Market Crash

A crash is a sudden, severe drop in prices over days, driven by panic, not fundamentals alone.

Using it in practice

Build your portfolio so a crash is survivable before one happens: avoid leverage, hold a cash buffer, and keep an allocation you can hold through a 30% drop. A crash is the price of admission to equity returns — the plan is what makes it payable.

Where people go wrong

Crashes are obvious only after; trying to time them is futile for most.

Example in numbers

Why investors care

It is the event that tests whether your plan was real.

In the real market

On a single Monday in 1987, the market fell 22% with no warning. Investors who were leveraged were wiped out by Tuesday; those who owned diversified holdings and did nothing were back to even within two years. In 2020, the market fell 34% in five weeks — then completed the fastest recovery in history, making new highs in under six months. The scenario that separates outcomes in every crash is not prediction; it is whether the investor could hold, and whether leverage forced them not to.

Key takeaway

A crash is a fast, violent, broad plunge driven by panic and forced selling — impossible to time and survivable only with a plan. They hit when confidence is highest, they are shorter than bears but far more brutal, and history shows markets eventually recover for those who can hold. Leverage is the difference between a painful drawdown and a wiped-out account. Build the portfolio so a crash is survivable before it arrives, because prediction will not save you; preparation will.
