Market Cycles: Bull and Bear Markets, Drawdowns and Staying Invested

How bull and bear markets behave, what drawdowns really cost, and why staying invested wins.

Markets do not move in a straight line — they cycle between bull markets, where optimism and rising prices feed each other, and bear markets, where fear does the same in reverse. In 2026, the S&P 500 has cycled through three bear markets in a generation, and each one convinced a cohort of investors to sell. The math of cycles is unforgiving but simple: the recovery from a drawdown always requires more percentage gain than the drawdown you just suffered, and history says the investors who stayed invested through the pain captured almost all the returns.

Anatomy of a cycle: bull, peak, bear, trough

A bull market is typically defined as a 20%+ rise from a low; a bear market as a 20%+ fall from a high. Bulls last longer and climb more; bears are shorter and faster. Since 2000 the US market has lived through several complete cycles, each with its own trigger — speculation, credit, a pandemic, an inflation shock — and the same shape every time.

Recent S&P 500 bear markets, with time to recover the old high
Bear marketPeak to troughYears to new high
2000-2002 (dot-com) -49% About 7 years
2007-2009 (financial crisis) -57% About 5 years
2020 (pandemic) -34% About 6 months
2022 (inflation, rates) -25% About 2 years

Drawdown math: what -40% really costs

The asymmetry of drawdowns is the first number every investor should memorize. A 20% loss needs 25% to recover; a 40% loss needs 67%; a 50% loss needs 100% — a full doubling just to get back to even. This is why bear markets punish the sellers: they convert a temporary price drop into a permanent capital loss at exactly the wrong time.

The recovery ladder

                -20% → need +25% to break even
-33% → need +50%
-40% → need +67%
-50% → need +100%
Sell at -40% and buy back at the top: the missing 67% is paid in cash, not time
              

Staying invested: the cost of missing the best days

The classic study of US market history keeps arriving at the same conclusion: a handful of days produces most of the return. Over the 20 years to 2021, $10,000 in the S&P 500 grew to roughly $64,000 — but missing just the 10 best days left about $33,000, and missing the 30 best days left under $20,000. The best days cluster around market bottoms, exactly when fear tells you to be out. You cannot reliably skip the worst days without skipping the best ones, because they arrive in the same weeks.

The market's worst days and best days happen within days of each other. Being out for the panic means being out for the recovery.

Dollar-cost averaging, rebalancing and the cycle

Cycles are unforecastable in advance, which is exactly why mechanical rules beat predictions. Dollar-cost averaging buys more shares when prices are low and fewer when they are high, so a bear market quietly becomes a buying opportunity if your contributions continue. Rebalancing forces you to sell what went up and buy what went down — the contrarian discipline in a single rule. The lump sum vs DCA calculator quantifies the tradeoff, and the investment return calculator shows what an unchanged contribution schedule does across any cycle.

None of this means ignoring bear markets. They are when risk shows its true price: a 25% drawdown on a 100% stock portfolio is a $25,000 hole on $100,000, while the same portfolio at 60% stocks takes a $15,000 hit. Cycle planning is mostly asset allocation — sizing the downside you can hold through, because the only strategy that reliably loses in a cycle is the one that sells at the bottom. The CAGR article shows why the average return you see quoted is usually higher than the return you actually pocket through volatility.

Frequently asked questions

How long do bear markets typically last?
US bear markets since World War II have averaged roughly 14 months from peak to trough, though some run longer — the 2007-2009 bear lasted 17 months. Recoveries are the variable part: from weeks (2020) to years (2000-2002), which is why time horizon matters more than timing skill.
Should I sell everything in a bear market?
History says no. Selling locks in the loss, and the recovery's best days cluster near the bottom — investors who missed the 10 best days in a 20-year period kept barely half the ending value. If a drawdown genuinely threatens your plans, the portfolio was too aggressive; fix allocation, not timing.
How much do stocks drop in an average bear market?
The S&P 500's modern bear markets have ranged from about -20% to -57%, with an average decline near -35%. The depth depends on the cause: valuation-driven bears tend to be deeper and longer, while event-driven bears (like 2020) reverse fastest.
How do I profit from market cycles?
Not by predicting them — even professionals cannot time tops and bottoms consistently. The dependable edge is mechanical: keep contributing through downturns (dollar-cost averaging), rebalance annually to buy the losers, and never let a drawdown exceed what your sleep and your spending plan can tolerate.
