Bear markets are among the most psychologically testing experiences an investor can face. Portfolios shrink, headlines darken, and every instinct urges action. Yet the investors who emerge best from bear markets are almost always those who understood what was happening — and chose discipline over panic.
What Is a Bear Market?
A bear market is defined as a decline of 20% or more from a recent peak in a broad market index, sustained over at least two months. This distinguishes it from a "correction" (a 10–20% pull-back, often short-lived) and from a one-day crash.
The 20% threshold is conventional, not regulatory. What matters practically is that a bear market represents a sustained deterioration in investor sentiment, often accompanied by worsening economic fundamentals.
Historical Bear Markets: How Long Do They Last?
Since 1928, the US S&P 500 has experienced around 27 bear markets. The average peak-to-trough decline has been approximately 35%, and the average duration from peak to the eventual recovery of losses has been around 14 months — though this masks significant variation.
Notable examples include:
- The Great Depression (1929–1932): A catastrophic 86% decline. Recovery to prior highs took over 25 years for a nominal investor not reinvesting dividends.
- The Dot-Com Crash (2000–2002): The Nasdaq fell around 78% from peak. Recovery took over a decade for tech-heavy investors.
- The Global Financial Crisis (2007–2009): The S&P 500 fell 57%. Full recovery took about four years.
- The COVID Crash (2020): Exceptional in its brevity — a 34% decline in 33 days, followed by full recovery in roughly five months, aided by massive fiscal and monetary stimulus.
UK markets tell a similar story. The FTSE 100 has experienced comparable bear markets, though its heavier weighting toward commodities, financials, and energy gives it somewhat different dynamics from the US market.
The key takeaway: bear markets end. Not always quickly, but they end. Investors who remain invested capture the recovery; those who sold typically do not.
The CAPE Ratio as a Valuation Signal
The Cyclically Adjusted Price-to-Earnings (CAPE) ratio, developed by Nobel laureate Robert Shiller, smooths earnings over ten years to reduce cyclical distortion. It is one of the more reliable long-run valuation indicators, though it is a poor market-timing tool.
A high CAPE — above 30 for the S&P 500 — has historically preceded periods of below-average real returns over the following decade. It does not, however, tell you when a bear market will begin or how deep it will be.
As of 2026, the CAPE ratio for US equities remains elevated by historical standards. This does not mean a crash is imminent, but it does suggest that investors should temper long-run return expectations and ensure they are not over-concentrated in expensive markets.
What Not to Do in a Bear Market
Selling in Panic
The single most destructive act most investors take in a bear market is selling after a large decline. Studies consistently show that retail investors buy near tops and sell near bottoms — capturing losses rather than recoveries. Missing even the ten best trading days in a decade can cut long-term returns by half.
Holding 100% Cash Waiting for the Bottom
The temptation to wait for the market to "bottom out" before re-entering is equally damaging. Bottoms are only visible in hindsight. Investors who sell and wait for the "all-clear" typically miss the most violent part of the recovery — which historically occurs in the early months after a trough, often before any positive economic news.
Overreacting to Financial Media
Bear markets attract relentless negative coverage. Headlines confirm the fear. Switching off the financial news and sticking to your plan is often the most valuable thing you can do.
Strategies That Work
Not Selling
For a long-term investor with a horizon of ten years or more, the dominant evidence-based strategy is simply: do not sell equity. Ride out the bear market. This requires emotional resilience, adequate cash reserves so you are not forced to sell, and genuine conviction that diversified markets recover over time.
Pound-Cost Averaging In
If you have cash — whether from regular savings or a recent liquidity event — a bear market is precisely when you should be deploying it. Pound-cost averaging (investing a fixed sum at regular intervals) means you buy more units when prices are lower, reducing your average cost base. Investors who added to portfolios in March 2009 and March 2020 generated exceptional returns.
Tax-Loss Harvesting
A bear market creates opportunities to crystallise losses for tax purposes. In the UK, capital losses can be offset against capital gains in the same tax year or carried forward indefinitely. For an investor with embedded gains elsewhere — in property, for instance — realising equity losses during a bear market to offset those gains can have meaningful tax value. Investors should take care not to repurchase the same asset within 30 days (the "bed and breakfast" rules) without using an ISA or SIPP wrapper to shelter the re-entry.
Rebalancing
If your asset allocation calls for, say, 70% equities and 30% bonds, a bear market will push you below target in equities. Systematic rebalancing — selling bonds and buying equities to restore target weights — forces the counterintuitive but mathematically sound act of buying more of what has fallen. See the article on portfolio rebalancing for the evidence base behind this discipline.
Reviewing Asset Allocation
A bear market is a useful diagnostic: if watching your portfolio fall 30% is causing acute anxiety, your allocation may have been too aggressive relative to your actual risk tolerance (not your stated risk tolerance). Adjusting at the bottom is still costly; but a genuine reassessment of how much equity risk is appropriate can be done at any time.
Bear Market Traps
The Dead Cat Bounce
After a sharp decline, markets often stage a brief but sharp recovery — sometimes 10–15% over a few weeks — before resuming the downtrend. This is known as a dead cat bounce. Investors who sold near the top, watched the initial decline, and then re-entered on the bounce can find themselves buying at an elevated point only to see renewed falls. The dead cat bounce feeds the misguided conviction that the bear market is over before it is.
Catching Falling Knives
Similarly, individual stocks or sectors that have declined sharply can look like "bargains." Sometimes they are. Sometimes they are companies in structural decline, or sectors facing permanent disruption — and the decline continues to zero. Concentration into single names during bear markets is one of the riskier strategies available.
How Bonds Behave in Bear Markets — It Depends
The popular wisdom that bonds rise when equities fall is true in some bear markets but not all. In a demand-shock recession (such as 2008), investors flee to government bonds (gilts, US Treasuries), pushing yields down and prices up — bonds do their job as a diversifier.
However, in a supply-shock or inflation-driven bear market (as in 2022), central banks raise rates to tackle inflation. Both equities and bonds fall simultaneously — a so-called "correlation breakdown" that caught many diversified portfolios off guard. In 2022, the classic 60/40 equity-bond portfolio suffered its worst year in decades.
The implication: bond duration (interest-rate sensitivity) and bond quality (credit risk) matter enormously. Short-duration, high-quality bonds provide more resilience in inflationary environments. In a recession-driven equity sell-off, long-duration government bonds typically perform better.
Practical Steps Before and During a Bear Market
- Maintain an adequate cash buffer. Three to six months of living expenses — more for retirees drawing from their portfolio. If you are not forced to sell, you cannot be forced to crystallise losses.
- Review your asset allocation honestly. Can you stomach a 40% draw-down without changing plan? If not, reduce equity exposure in calmer times, not during a panic.
- Continue regular contributions. If you have a regular savings plan into a pension or ISA, keep it running. You are buying more units at lower prices.
- Consider tax opportunities. Loss harvesting, ISA contributions, pension top-ups.
- Read less daily financial news. Check quarterly, not daily.
