Bull vs Bear Market: What They Mean and How Each Looks on a Chart
A bull market is a sustained rise in stock prices with optimistic sentiment, generally 20% or more in a broad index. A bear market is a sustained fall of 20% or more with pessimistic sentiment. Here is where the line comes from, how corrections differ, how long each tends to last, what each looks like on a chart and what changes for a trader.
Bull vs bear market, in plain terms. A bull market is a stretch where stock prices keep rising and the mood is optimistic. A bear market is the reverse, prices keep falling and the mood turns pessimistic. Investor.gov puts a number on it. Generally, a bull market is a rise of 20% or more in a broad market index over at least a two-month period, and a bear market is a fall of 20% or more over at least a two-month period.
Most explainers stop there because they're written for people holding funds for twenty years. I trade intraday, so this one spends more time on what each regime looks like on a chart and what actually changes when you're the one clicking buy or sell.
Quick Answer
What is a bull market? A sustained rise in stock prices with optimistic sentiment, generally 20% or more off a low in a broad index. What is a bear market? A sustained fall with pessimistic sentiment, generally 20% or more off a high. The bull vs bear market difference is direction and mood. On a chart, a bull market prints higher highs and higher lows, and a bear market prints lower highs and lower lows. The 20% line is a convention, and it only confirms a regime after the move is well underway.
This is education, not advice. The Harborline 500, the index in the examples, is made up, and so are its levels.
What Is a Bull Market vs a Bear Market?
What is a bull market in stocks, beyond the one-liner? It's a period where prices across the market trend up for months or years, dips get bought, and people are broadly confident about earnings and the economy. A bear market is a period where prices trend down, rallies get sold, and people expect things to get worse before they get better.
The 20% figure is a convention, not a rule anyone enforces. Look at the wording on Investor.gov: "Generally, a bear market occurs when a broad market index falls by 20% or more over at least a two-month period." That "generally" is doing real work. Nobody rings a bell at 19.9%. Markets can feel bullish or bearish for months without crossing the line, and plenty of people describe a weak stretch as bearish long before the official count gets there.
Two details matter when people argue about whether it "counted". First, it's measured on a broad index such as the S&P 500, not on one stock. Second, the count is usually done on closing prices. An index can trade below the 20% mark intraday, bounce, and close above it, and then you get a week of headlines arguing about whether it was a bear market or not. The definition hasn't changed. People are just measuring from different prints.
Sentiment feeds itself
Both regimes are self-reinforcing. In a bull market, rising prices make people feel richer and more confident, so they buy, which pushes prices higher, which pulls in more buyers. In a bear market the loop runs the other way. Falling prices make people nervous, they sell, prices fall further, and more people sell to avoid the next leg down. Under the hood it's supply and demand. When more people want to buy than sell, price rises, and the reverse when sellers outnumber buyers. Sentiment just decides which side shows up.
The economy, with one big caveat
Bull markets tend to line up with economic growth, rising company profits and low unemployment. Bear markets tend to line up with slowdowns, falling profits and rising unemployment. But a bear market is not a recession. The stock market looks ahead, so it often falls before the economy weakens and recovers before the economy feels better. Hartford Funds, in its summary of bear market history, counts 27 bear markets since 1928 against 15 recessions over the same period, citing the National Bureau of Economic Research for the recession count. Plenty of bear markets happened without one.
What usually starts a bear market
No single cause, but the usual suspects:
- Fear and uncertainty.Investors stop paying up for future earnings when they can't see the future.
- A bubble bursting. Prices that ran far ahead of reality come back down, often fast.
- Shocks. A pandemic, a war, a financial crisis. Things nobody priced in.
- Inflation and rising interest rates. Higher rates make borrowing more expensive and make future profits worth less today.
Bull markets tend to start from the opposite set: fear fading, rates easing, profits recovering.
Correction or Bear Market? How Deep Is Deep Enough
Not every drop is a bear market. A fall of roughly 10% to just under 20% from a recent high is usually called a correction. If it keeps going and reaches 20%, the correction gets upgraded to a bear market. Smaller dips of about 5% to 10% get called pullbacks. None of these smaller labels come from a regulator. They're market convention, and you'll see sources draw the edges slightly differently.
So "the market is down 12%" is a correction, not a bear market. The ladder on the made-up Harborline 500:
| Label | Usual depth | What the chart tends to show | Harborline 500 example |
|---|---|---|---|
| Pullback | Roughly 5% to 10% off a recent high | Usually just a dip inside the uptrend. Higher lows often survive. | A drop from 5,000 to about 4,700 |
| Correction | Roughly 10% to just under 20% | Deeper. Can break the last higher low, but the bigger trend may still hold. | 5,000 down to 4,500 (down 10%) |
| Bear market | 20% or more, on a broad index, generally over at least two months | Lower highs and lower lows. Rallies keep stalling below the last high. | 5,000 down through 4,000, bottoming at 3,600 (down 28%) |
The chart point most explainers skip: a lot of corrections stop short of 20% and the bigger uptrend carries on. What tends to separate a correction from the start of a bear market isn't the first 10%, it's what happens on the next bounce. If the bounce makes a new high, the uptrend is intact. If it stalls below the old high and the next drop goes lower, the structure has flipped.
How Long Does a Bear Market Last?
How long does a bear market last? Historically, a lot less time than a bull market. Bear markets have tended to run for months, bull markets for years. Hartford Funds, citing Ned Davis Research data as of 3/31/25, puts the average S&P 500 bear market since 1928 at 289 days, about 9.6 months, and the average bull market at 988 days, about 2.7 years.
Treat any single number with suspicion, including that one. Other studies from different brokers and research shops land somewhere between roughly 9 and 16 months for the average bear, because they start the clock in different years, use different indexes and count the start and end points differently. Averages also hide a wide spread. Some bear markets have been over in weeks, others dragged on for years. None of it tells you how long the next one lasts.
You only know for sure in hindsight
The 20% rule confirms things late by design. A bear market is dated from the prior peak, but you only know it was the peak once the index is already down 20%. A bull market is dated from the bottom, but it only gets the label after a 20% rise off that bottom, so by the time it's official the move is well underway. In real time, the low looks like just another down day.
That's why nobody reliably times the turns. Plenty of smart people try every cycle. The investor advice that follows from this (stay diversified, don't panic sell) is a different post. For a trader, the takeaway is narrower: don't wait for the label to tell you what the chart already shows.
Why Is It Called a Bull vs Bear Market?
So why is it called a bull and bear market? The usual explanation is how each animal attacks. A bull thrusts its horns up. A bear swipes its claws down. Up market, down market.
There's a competing story. An old proverb warned against selling the bear's skin before you'd caught the bear. Traders who sold shares they didn't own yet, hoping to buy them back cheaper, got tagged with the bear name. In that version, "bull" got picked up as the natural opposite. The terms themselves are usually dated to the 1700s. Honestly, it's folklore. The origin is debated and no source settles it, so take whichever version you like at parties.
What a Bull and a Bear Market Look Like on a Chart
The 20% count is an investor's yardstick. Traders read trend straight off the structure, and on a bull vs bear market chart the difference is visible without any math.
- Bull market structure: higher highs and higher lows. Each rally clears the last high, each dip holds above the last low.
- Bear market structure: lower highs and lower lows. Each rally stalls below the last high, each drop breaks the last low.
- The turn:after a run of lower lows, the first higher low followed by a higher high is the earliest structural sign that the bear may be over. It's also where most false starts happen.
If you mark those swings with lines, the guide to drawing trendlines and the primer on support and resistance cover the mechanics. If reading swing highs and lows is new to you, the beginner's guide to reading stock charts covers candles and structure from scratch. This is the whole cycle on the made-up Harborline 500:
One bull to bear to bull cycle on a made-up index
Walk through it. The index climbs in higher highs and higher lows to a peak at 5,000. The first drop reaches 4,500, down 10%, a correction. The bounce stalls at 4,800, below the peak. That lower high is the warning. The next leg closes below 4,000, the 20% line, which makes it a bear market by the usual count, and that leg bottoms at 3,900, down 22% from the top. A 9% rally to 4,250 fails below the prior lower high, and price drops to the bottom at 3,600, down 28% from the peak.
Then the turn. A 14% bounce to 4,100 isn't a bull market by the 20% count, but the pullback after it holds at 3,800, above the bottom. That's the first higher low. The next push clears 4,100 for a higher high and keeps going to 4,400, crossing 4,320 on the way, which is 20% off the bottom. Only then does the bull label apply, and by that point the index is already up 22% from the low. The structure flagged it earlier, with more risk of being wrong.
The long moving average rule of thumb
The other common read is price against a long moving average, often the 200-day. Price holding above a rising long average is the classic bullish read. Price living below a falling one is the bearish read. It's a heuristic, not a definition, and it lags for the same reason the 20% rule does, because it's built from past prices. You can see that in the diagram. The dotted average keeps sliding well after the bottom and is only just turning up at the right edge. The explainer on how a simple moving average is calculated covers why it trails price, and the post on the 50-day and 200-day crossover signals covers what happens when two averages cross. If you want a whole framework built on price versus a long average, the four-stage cycle from Stan Weinstein maps closely onto bull and bear phases.
What is a bear market rally?
What is a bear market rally? A sharp counter-trend bounce inside a bear market. They can be violent, and on individual stocks even more so, partly because short sellers rush to cover. They feel like the bottom. Many of them fail at a lower high, like the 4,250 rally in the diagram, and the downtrend resumes.
The tell on a chart is the rally that doesn't take out the prior high. A bull market is a sustained uptrend that keeps making new highs. A bear market rally is a burst that runs out of buyers below the last lower high. Breakouts in that zone fail a lot, which is the same mechanic behind the false breakouts that trap traders on both sides. And if you're tempted to buy every flush on the way down, the difference between a healthy dip and a falling knife is worth reading first.
Timeframes nest
A stock can be in an intraday uptrend inside a daily downtrend inside an index bear market. All three are true at once. A five-minute chart can print beautiful higher highs while the daily chart is a staircase down. Checking the timeframe above the one you trade, before you trade it, is the cheapest habit there is. The walkthrough of reading trend across timeframes goes deeper on that.

The full bull vs bear market comparison, including the trader rows that investor guides leave out:
| Topic | Bull market | Bear market |
|---|---|---|
| Investor.gov wording | Generally a rise of 20% or more in a broad index over at least two months | Generally a fall of 20% or more in a broad index over at least two months |
| Mood | Optimistic. Buying tends to feed more buying | Pessimistic. Selling tends to feed more selling |
| Chart structure | Higher highs and higher lows | Lower highs and lower lows |
| Price vs a long moving average | Mostly above a rising one (rule of thumb, not a definition) | Mostly below a falling one (same caveat) |
| Dips and rallies | Pullbacks and corrections that tend to find buyers | Sharp rallies that often fail at a lower high |
| Typical economic backdrop | Growth, rising profits, low unemployment | Slowdown, falling profits, rising unemployment. Not the same thing as a recession |
| Length | Historically much longer | Historically much shorter, usually months rather than years (figures vary by source) |
| When you know for sure | After a 20% rise off the low, well after the bottom | After a 20% drop off the high, well after the top |
| Day-to-day ranges | Often calmer | Often wider, with more gaps |
| For a short-term trader | Long setups have the wind behind them more often | Longs fight the tide, targets shrink, shorts and failed rallies matter more, size comes down |
A day trader doesn't need the official label. You're in and out within the session, so what matters is the trend on the timeframe you trade and the one above it. Still, the broad regime leaks into every intraday chart, mostly in four ways.
Trend direction and long setups
In a bull tape, a lot of stocks drift up with the index, pullbacks tend to find buyers, and breakouts follow through more often. In a bear tape, longs are swimming against the current. More breakouts fail, moves run out of steam sooner, and targets that would have been reasonable a few months ago start looking greedy. That doesn't mean no longs. Stocks with their own catalyst still run. It means the bar for a long goes up, and a setup that's only so-so is easier to skip.
Shorts become more relevant
Failed rallies and breakdowns are where short setups live, and a bear market produces a lot of both. If you've only ever traded long, the breakdown of going long versus going short is a good starting point. Shorting has its own mechanics: you need a margin account, you need shares available to borrow, and the loss on a short has no ceiling if price keeps climbing. The step-by-step guide to shorting a stock covers borrowing, costs and the risks before you try it. Bear market rallies are exactly what squeezes shorts, so the same chart that gives you short setups also gives you violent bounces against them.
Wider ranges, smaller size
Bear markets tend to come with bigger daily ranges and more gaps. Wider ranges mean your stop has to sit further away to survive normal noise, and a wider stop at the same share count means a bigger loss when you're wrong. The fix is to hold your dollar risk fixed and let the share count shrink. The guide to volatility and position size walks through that math, and the rundown of the different gap types covers what an opening gap can do to a stop.
Holding period changes how much it matters
The longer you hold, the more the regime matters. A scalper in and out in ten minutes mostly cares about the next few bars. Someone holding for several days carries overnight gaps and the broader drift, so the regime shows up directly in their results. If that's you, the primer on swing trading covers how multi-day holds work. Whatever your timeframe, the setups themselves don't change much between regimes. How often they work does, which is why the momentum trading playbook leans so hard on only taking the clean ones.
What a Chart Grade Sees, and What It Doesn't
SnapPChart grades one chart screenshot for momentum continuation, long or short. It reads the candles, EMAs, VWAP, MACD and volume visible in the image, and it can read the ticker label on the chart. So it can tell whether the chart in front of it is making higher highs and higher lows, where price sits against its moving averages, and whether volume backs the move. When a setup qualifies, you get an entry, a stop with the reasoning behind it, and targets.
What it doesn't know: whether the broad index is in a bear market, where the index is trading, what's in the news, or anything about the economy. It doesn't call tops or bottoms and it doesn't predict when a bear turns into a bull. Nothing does that reliably, and a tool claiming to would be lying to you.
So the split is simple. You check the regime yourself: index chart, structure, which side of the long average price is on. Then grade the setup on your own chart before you take it. The trade worth skipping is usually the C-grade long you talked yourself into while the tape was falling.

Frequently Asked Questions
Can a single stock be in a bear market?
People say it loosely, as in "this stock is in bear territory" after it falls 20% from its high. Strictly, the bull and bear market labels describe a broad index, not one company. A single stock can fall 40% while the index climbs, so treat the phrase as shorthand for "this stock is in a deep downtrend", not as a statement about the market.
Are we in a bull or bear market right now?
This post doesn't make calls, and the label only settles in hindsight anyway. You can check the mechanical version yourself: pull up a daily chart of a broad index, find its last major closing high, and see how far the latest close sits below it. Down 20% or more is bear market territory by the usual convention. Then look at structure: is it still printing lower highs, or has it made a higher low and a higher high?
Does a bear market mean I should only take short trades?
No. Plenty of individual stocks run hard on their own news while the index is falling, and bear markets produce some of the sharpest rallies there are. What tends to change is how picky you are with longs, how far you expect them to run, and how big you size. Shorting also needs a margin account and carries its own risks, so it isn't an automatic switch.
What's the difference between a secular and a cyclical bull or bear market?
Cyclical describes the regular swings that last months to a few years, the kind this post is about. Secular describes a much longer stretch, often a decade or more, where the overall direction holds even though cyclical bull and bear markets happen inside it. For a day trader, the secular label is background trivia. The cyclical regime and the trend on your own timeframe are what show up in your fills.
Does SnapPChart tell me whether it's a bull or bear market?
No. SnapPChart grades the one chart screenshot you upload for momentum continuation, long or short, by reading the candles, EMAs, VWAP, MACD and volume in the image. It can read the ticker label on the chart. It doesn't know index levels, the news, the economy or whether a bear market is official, and it doesn't call tops, bottoms or regime changes. Checking the regime is your job. Grading the setup in front of you is its job.
