Bear vs Bull Stock Market: What Each Market Cycle Means
The bear vs bull stock market distinction comes down to direction and size. A bull market is a sustained rise in a broad stock index, usually measured as a gain of at least 20% from a recent low. A bear market is a sustained fall, usually measured as a decline of at least 20% from a recent high.
Hartford Funds describes the convention plainly: an index reaches bear territory when its closing price drops at least 20% from its most recent high, and a new bull market begins when the closing price gains 20% from its low. The 20% line is a market convention, not an economic law. It gives investors and journalists a shared way to separate major trends from ordinary swings.
This page explains both terms, how they differ from corrections and recessions, what the long-run history shows, and where the S&P 500 stood in October 2026. It is educational information, not investment advice.

Bear vs Bull Stock Market at a Glance
The table below sets the two market states side by side. It describes broad tendencies, not rules that hold in every cycle.
| Feature | Bull Market | Bear Market |
|---|---|---|
| Direction | Rising prices | Falling prices |
| Common threshold | Gain of 20% or more from a low | Drop of 20% or more from a high |
| Typical sentiment | Optimistic | Pessimistic |
| Typical investor behavior | Greater appetite for risk | Greater caution |
| Economic backdrop | Often expanding | Often slowing, though not always |
| Historical length | Longer on average | Shorter on average |
| Common behavioral risk | Overconfidence and chasing gains | Panic selling and mistimed re-entry |
Market direction says nothing certain about what the economy, interest rates, or any single stock will do next. The table also leaves out timing: a phase is often named only after it has run for weeks or months, once the 20% move is confirmed by closing prices. A broad index can rise while many individual companies fall, and the reverse is also true.
What Is a Bull Market?
A bull market is a period when stock prices are rising across a broad index and sentiment is generally optimistic. The common measure is a closing gain of at least 20% from the most recent low. Hartford Funds uses that rule when it dates the start of each new bull market in the S&P 500.
Analysts usually apply the label to a broad benchmark such as the S&P 500, the Dow Jones Industrial Average, or the Nasdaq Composite. A single stock climbing 20% does not put the whole market in a bull phase. The label describes the overall market, and individual sectors can move in very different directions inside it.
What Is a Bear Market?
A bear market is a period when prices are falling across a broad index and sentiment is generally pessimistic. Fidelity defines it as a drop of 20% or more from recent highs, while Hartford Funds measures the decline from peak to trough using closing prices.
Bear markets are deeper than ordinary volatility. They are also deeper than corrections, which the next section covers. Because the threshold is measured from the last high, a bear market is only confirmed after the 20% drop has happened. That timing is one reason the term often appears in headlines after much of the decline is already over.
Bear Market vs Correction
A correction is a smaller pullback. Hartford Funds defines it as a drop of 10% to 19.9% from a recent high, while a bear market starts at 20%. Corrections are part of normal market behavior and many never become bear markets.
The difference can be close. Hartford notes that the S&P 500 fell 19.9% in 1990, just short of the bear threshold, which kept the bull market that began in December 1987 alive until March 2000. A one-tenth of a point gap decided which label applied, which shows how mechanical the 20% convention is.
How Long Bull and Bear Markets Have Lasted
The most consistent finding in the history of the bear vs bull stock market cycle is that upswings have tended to last longer than declines. The exact figures depend on which index and which years a study uses.
Fidelity's Data Since 1872
Fidelity's review of market cycles, dated September 2026, counts 26 bear markets and 26 bull markets in U.S. stocks since 1872. Bear markets lasted a median of 19 months with a median drop of 33%. Bull markets lasted a median of 42 months with a median gain of 87%.
The Ranges Are Wide
Fidelity's ranges show how far any single cycle can stray from the median. Bear markets ran from 1 month to 113 months, nearly nine and a half years. Bull markets ran from 14 months to 98 months, about eight years. A median describes the middle of the record, not a timetable for the next cycle.
| Measure (Fidelity, Since 1872) | Bull Markets | Bear Markets |
|---|---|---|
| Number observed | 26 | 26 |
| Median length | 42 months | 19 months |
| Median price move | +87% | -33% |
| Shortest | 14 months | 1 month |
| Longest | 98 months | 113 months |
What Hartford Funds Found for the S&P 500
A second dataset gives similar direction with different numbers. Hartford Funds' review of bear markets uses S&P 500 data from 1928 and measures each cycle from peak to trough.
Averages Since 1928
Hartford counts 27 bear markets and 28 bull markets in the S&P 500 since 1928. The average bear market lasted 289 days, about 9.6 months, with an average loss of 35%. The average bull market lasted 988 days, about 2.7 years, with an average gain of 112%. Fidelity's medians and Hartford's averages differ because the studies use different start dates and methods.
How Often Bear Markets Arrive
Hartford puts the long-term average gap between bear markets at about 3.5 years. Between 1928 and 1945 there were 12 bear markets, about one every 1.5 years. Since 1945 there have been 15, about one every 5.1 years. Over the last 95 years, Hartford counts about 21.4 years spent in bear markets.
The 2020 Bear Market Was Unusually Fast
The COVID-19 decline shows how far one cycle can depart from the averages. FRED's daily S&P 500 data show a record close of 3,386.15 on February 19, 2020, and a close of 2,237.40 on March 23, 2020.
That is a decline of about 33.9% in just over a month, a Fin Loom calculation from those two closes. The index then recovered quickly. By August 18, 2020, it closed at 3,389.78, above the February record. A full bear market and recovery fit inside six months, far shorter than either study's typical cycle.
The 2022 Bear Market Had Different Causes
The 2022 decline followed a different path. The S&P 500 closed at a record 4,796.56 on January 3, 2022. By June 16, 2022, it had closed at 3,666.77, about 23.6% lower, which placed it in bear territory.
June was not the bottom. The index closed at 3,577.03 on October 12, 2022, about 25.4% below the January peak, based on Fin Loom calculations from FRED closing data. Inflation and rising interest rates weighed on stocks through that year. The S&P 500 did not close above its January 2022 record until January 19, 2024, at 4,839.81, roughly two years after the peak.
A Bear Market Is Not the Same as a Recession
A recession is a broad decline in economic activity. A bear market is a large decline in stock prices. The two often overlap, but one does not require the other.
Hartford Funds counts 27 bear markets since 1928 but only 15 recessions in the same period. Stock prices reflect expectations about future profits, so they can fall before economic data weaken and can start recovering while conditions still look poor. Treating the two terms as interchangeable mixes a market measure with an economic one.
What Tends to Drive Each Market Cycle
No single cause explains every bull or bear market. Each phase reflects what investors expect about future earnings, interest rates, and risk, and those expectations can change quickly.
Conditions That Have Supported Bull Markets
Rising stock prices have often been linked to growing company earnings, an expanding economy, falling or stable interest rates, easier credit, gains in productivity, and new technology. Improving investor confidence can add to these effects. Not every bull market has all of these conditions, and stock prices can rise on expectations long before results appear.
Conditions That Have Preceded Bear Markets
Falling stock prices have followed recession fears, rising interest rates, inflation shocks, financial crises, credit stress, geopolitical conflict, falling earnings, and stretched valuations. Sudden disruptions such as the 2020 pandemic can also trigger them. The trigger has varied widely from one cycle to the next, which makes it hard to generalize from any one episode.
Where the S&P 500 Stood in October 2026
The term "bear market" is often used loosely during any volatile stretch, so current data help anchor the discussion. These figures come from FRED's daily S&P 500 series, which tracks the price index without dividends.
The 2026 Price Path
The S&P 500 closed 2025 at 6,845.50. On October 21, 2026, it closed at 7,757.17, a price gain of about 13.3% for the year to date, a Fin Loom calculation. The record close for 2026 so far was 7,818.93 on October 6, so the October 21 close sat about 0.8% below that high.
The Largest Pullback of 2026
The deepest decline of the year in this series ran from a close of 6,978.60 on January 27 to 6,343.72 on March 30. That drop was about 9.1%, a Fin Loom calculation, short of the 10% correction threshold and far from a 20% bear market. These figures describe the past and do not indicate where prices will go next.
Bullish and Bearish Are Different From Bull and Bear Markets
"Bullish" and "bearish" describe a view or outlook. "Bull market" and "bear market" describe what a broad index has done. An analyst can be bearish on one sector while the S&P 500 sits in a bull market, or bullish on one company during a market-wide decline.
Mixing the two causes confusion in headlines, and it blurs the bear vs bull stock market distinction that depends on index data rather than opinion. A forecaster turning bearish does not mean a bear market has started. That label applies only after a broad index has closed at least 20% below its high. Tools that read price trends, covered in technical analysis for stocks, describe direction without settling which phase comes next.
Why Market Cycles Are Hard to Time
Bear markets often include sharp rallies, and some of the strongest single days happen during periods of heavy volatility. Hartford Funds found that 42% of the S&P 500's strongest days in the last 20 years occurred during a bear market. Another 36% came in the first two months of a bull market, before it was clear a new bull had begun.
That pattern creates a timing problem. A person who sells after a large decline has to be right twice: once about when to exit and again about when to re-enter. Missing a handful of the strongest days can change long-run results, and those days have tended to cluster near the worst ones.
How Each Market Phase Can Affect Investor Behavior
Both phases carry risks that come from behavior rather than from the market itself. Knowing the common patterns helps explain why investors often make different choices in each phase.
Risks People Report in Bull Markets
Rising balances can encourage chasing recent winners, using more borrowed money, concentrating in a few holdings, overlooking valuation, and assuming recent gains will continue. A strong market does not remove risk. Company-level fundamentals still shape outcomes, which is the focus of stock analysis fundamentals.
Risks People Report in Bear Markets
Falling balances can prompt panic selling, abandoning a long-term plan, or buying a stock only because its price has dropped. A falling price can reflect a weaker business, so a lower price is not by itself a sign of value. Dividend payers face their own questions in downturns, which highest yield dividend stocks covers through payout coverage and debt.
Comparing the Bear vs Bull Stock Market Record
Taken together, the bear vs bull stock market record shows a consistent asymmetry: rising phases have lasted longer and gained more than falling phases lost. Fidelity's medians, Hartford's averages, and the 2020 and 2022 examples all point the same way.
The record also shows wide variation. A bear market has lasted as little as a month and as long as nine years. The 20% rule is a label applied after the fact, and history offers context rather than a forecast. Understanding the bear vs bull stock market definitions makes headlines easier to read, but it does not reveal what the next cycle will look like.
