A bull market and a bear market describe two opposite directions the same market can move in over time. This guide covers where the terms come from, how each one is identified, and why the label describes what already happened rather than what comes next.
What is a bull market and what is a bear market?
What is a bull market and what is a bear market?
A bull market is a sustained period of rising prices across a market, and a bear market is a sustained period of falling prices across that same market. The terms describe the general direction of an entire market, such as a stock market or a crypto market, rather than the price of one company or one asset. A market earns either label only after the move has lasted for a while, not the moment prices first shift.
The names come from how each animal attacks. A bull thrusts its horns upward, which is used as an image for prices pushing higher over time. A bear swipes its paw downward, which is used as an image for prices being pushed lower. The terms have been used in financial writing for a very long time, long before crypto markets existed, and they were later adopted by crypto commentary because the same up-and-down pattern shows up there too.
Because a bull or bear market describes a whole market, it is usually identified by looking at a broad index rather than a single company's share price. A stock index tracks a basket of companies together, so a steady rise across that basket points to a bull market and a steady decline points to a bear market. A single stock can fall while the wider market is still in a bull phase, and it can rise while the wider market is in a bear phase.
There is no single official rule for exactly when either one begins or ends, but a decline of roughly 20% from a recent high is a commonly cited rule of thumb for calling a bear market. A bull market has no equivalent fixed threshold and is generally recognised by a sustained climb over weeks or months. Either way, the label is applied looking backward at a move that has already happened. It describes what a market has done, not what it will do next.
Labels describe the past, not the future
A market is only called a bull or bear market once a sustained move has already taken hold. The name explains what happened, it is not a signal for what happens next.
How does sentiment differ between a bull market and a bear market?
How does sentiment differ between a bull market and a bear market?
Sentiment tends to run differently in each. A bull market is generally associated with optimism among market participants, more new buyers taking part, and prices climbing in a fairly steady way over an extended stretch. Trading activity in a bull market often builds gradually as more people join in.
A bear market is generally associated with caution or pessimism, and it can include sharper swings in both directions even while the overall trend points down. A single bear market can contain days or weeks where prices bounce higher before continuing to fall. That volatility is part of why a bear market is usually harder to sit through than a bull market, even though both are simply periods defined by price direction.
Neither label is permanent. A long bull market can include a short, sharp downturn without the whole trend being reclassified, just as a long bear market can include a short rally. Analysts sometimes use a separate term, such as a correction, for these shorter moves inside a bigger trend, which is one more reason the bull and bear labels are best read as a description of a broad, sustained direction rather than a day-to-day scorecard.
Do bull and bear markets apply to crypto markets too?
Do bull and bear markets apply to crypto markets too?
Bull and bear market language did not start with crypto, but it applies there in the same way. A crypto market can be described as a bull market during a sustained climb across major crypto assets, and as a bear market during a sustained decline, using the same broad, whole-market definition described above. Traditional stock markets and crypto markets are covered by the same two words because both move through extended up and down phases.
Because the bull or bear label only gets applied once a move has already been sustained for a while, it is not a signal that tells anyone what to do next. Prices in either type of market can still move against expectations, and a bear market can turn or a bull market can stall without warning. That uncertainty is exactly why understanding how to manage risk matters in both kinds of markets, not just one.
This is true across both stock and crypto markets. Whatever a market is currently labelled, prices can still move in ways that are hard to predict, which is why a plan for managing risk matters in a bull market and a bear market alike.

FAQ
How long does a bull market or a bear market usually last?
There is no fixed length for either. A bull market can run for months or years, and the same range applies to bear markets. Because the label only gets applied once a move has already been sustained, how long a current move will run cannot be known while it is happening.
Is a 20% decline the official definition of a bear market?
No. It is a widely cited rule of thumb rather than an official rule, and different analysts sometimes use a different threshold or apply it to one sector rather than a whole market. The core definition is a sustained decline in prices, the percentage is just a common shorthand.
Do these terms only apply to the stock market?
No. Bull and bear market language is used to describe any market with widely tracked prices, including crypto markets, not just stocks. The same idea, a sustained rise or a sustained fall across a whole market, applies either way.
