Bear Markets: How Deep They Go, How Long They Last, and What Recovers
A bear market (a fall of 20% or more from a peak) is not a malfunction; it is a recurring feature of owning stocks. US large caps have seen roughly a dozen of them since World War II, arriving every half decade or so on average, wildly irregularly in practice.
What separates investors who come through them intact is mostly rehearsal: knowing, in numbers, what bears have looked like, so the real one feels like weather instead of an ending. Here is the anatomy, and a way to rehearse on your own portfolio.
The historical shape of a bear
Every bear is different, but the historical envelope is well documented. Approximate figures for notable US bear markets, peak to trough:
| Bear market | Depth | Fall lasted | Back to prior peak |
|---|---|---|---|
| 1973 to 1974 (oil shock) | about -48% | about 21 months | several years |
| 2000 to 2002 (dot-com) | about -49% | about 31 months | about 7 years |
| 2007 to 2009 (financial crisis) | about -57% | about 17 months | about 5.5 years |
| 2020 (pandemic) | about -34% | about 1 month | under 6 months |
| 2022 (rate shock) | about -25% | about 9 months | about 2 years |
What the table actually teaches
Three patterns matter more than any single number:
- •Typical bears fall roughly 25% to 50%; the catastrophic half-off outcomes have come from bubbles or systemic crises, not ordinary recessions.
- •The fall is usually faster than the recovery, and the recovery timeline is the number that should size your cash cushion and your nerves.
- •Recoveries begin while the news is still terrible, which is why the timing guide's missed-best-days problem is really a bear-market problem.
A diversified portfolio is not the index
Headlines quote the stock index; you own a portfolio. A 60/40 stock/bond mix historically fell far less than stocks alone in most bears (2022 was the painful exception, when bonds fell alongside stocks), and single stocks can behave far worse than any index: some never recover at all. Diversification does not dodge bears; it narrows the range of what one can do to you and shortens the road back.
That is also the honest warning about concentration: an index has always eventually recovered so far; an individual company carries no such tendency (see the concentration guide).
Rehearse before it happens
The productive response to bear-market fear is specific numbers about YOUR portfolio: what would it have lost in 2008, in 2020, in 2022; how many months underwater; what the recovery looked like with dividends reinvested. Run the stress test, look at the drawdown chart, and decide in calm weather whether the mix passes the sleep test. If it does not, adjust the allocation now, at full prices, rather than at the bottom.
Rules complete the rehearsal: automated contributions keep buying through the trough, and scheduled rebalancing mechanically buys the fallen asset. Both convert a bear from a threat into a discount, without requiring courage in the moment.

FAQ
- How long does an average bear market last?
- Historically, the falling phase of US bear markets has commonly run several months to a couple of years, with full recoveries ranging from months (2020) to the better part of a decade (after 2000). Averages hide that spread; plan for the range, not the average.
- How far do stocks usually fall in a bear market?
- Roughly 25% to 40% has been common historically, with severe crises reaching about 50% or more. A diversified stock/bond portfolio has usually fallen materially less than the stock index alone (2022 being a notable exception).
- Should I sell when a bear market starts?
- By the time a bear is official, much of the damage is often done, and re-entering requires a second correct call at maximum fear (see the timing guide). The durable fix is holding an allocation whose bear-case you can survive, decided in advance. Education, not advice.
- Do all portfolios recover from crashes?
- Broad diversified indexes have always eventually made new highs so far, though sometimes only after many years. Individual stocks carry no such tendency, which is a core argument for diversification.
