Market Crash

A crash differs from a bear market mainly in speed. Bear markets tend to develop over months; crashes happen in days or weeks. Famous crashes include Black Monday (October 19, 1987, -22.6% in one day), the dot-com implosion (2000–2002, -78% in Nasdaq), the 2008 financial crisis, and the COVID-19 crash (March 2020, -34% in 33 days).

Crashes are almost impossible to predict precisely, but they share common preconditions: excessive valuations, high leverage, speculative euphoria, and then a catalyst that breaks confidence. Once panic sets in, margin calls and forced selling can accelerate the decline far beyond what fundamentals justify.

Example: During the 2008 financial crisis, major bank stocks like Citigroup fell over 90% from peak to trough. A $100,000 investment became $10,000. For investors with cash ready, the same crisis offered the buying opportunity of a generation — the S&P 500 rose over 400% in the next decade.

The BMInsider Fear & Greed Index tracks multiple market signals in real time — during crashes, it reliably hits 'Extreme Fear' levels that historically have marked or been near major market bottoms.
