What Is a Bull Market vs a Bear Market?

If you follow the news for even a week, you will hear that the market is “bullish” or that fears of a “bear market” are growing. These two animals are the oldest shorthand on Wall Street for the two directions a market can travel: up or down. A bull market is a long stretch of rising prices and optimism. A bear market is a deep, sustained fall, usually a drop of 20% or more from a recent high. This guide explains what each one really means, why markets swing between them, and, most importantly, how a beginner should think and behave in each phase.

What a Bull Market Is

A bull market is a prolonged period in which prices across the broad market are rising and investor confidence is high. The phrase is usually applied once a major index has climbed roughly 20% from its most recent low and keeps trending upward. The name is often traced to the way a bull attacks by thrusting its horns upward, a fitting image for a market pushing higher.

Bull markets tend to travel with a healthy economy. Companies are growing their profits, unemployment is usually low, and households feel comfortable spending. That confidence feeds on itself: as prices rise, more people want to buy, which pushes prices higher still. For a newer investor, a bull market is the easy, encouraging phase. Account balances climb, the headlines are cheerful, and investing feels straightforward. The hidden danger is that the good mood can tempt you into taking more risk than you should, chasing whatever has gone up the most, or believing the rise will simply continue forever. It never does.

What a Bear Market Is

A bear market is the opposite phase: a deep and sustained fall in prices. The widely used definition, including by the regulator FINRA, is a decline of 20% or more in a broad market index from its recent high. The bear imagery fits too, since a bear swipes its paws downward. A shallower slide of between 10% and 20% has its own name, a correction, and corrections are far more common and usually pass quickly.

Bear markets often arrive when the economy is weakening. Consumer spending slows, company earnings shrink, unemployment can rise, and the confidence that powered the bull run drains away. Fear takes over, more investors sell than buy, and prices fall further. This is the genuinely hard phase, because watching your balance drop is uncomfortable and the news will be relentlessly gloomy. Yet a bear market is a normal, recurring part of investing, not a sign that the system is broken. Understanding that in advance is half the battle.

Bull and Bear at a Glance

The two phases are mirror images across price direction, mood, and the economic backdrop. The table below sums up the typical features of each, though no two cycles are identical.

Why Markets Swing Between the Two

Markets do not rise or fall forever. They move in cycles, and bull and bear markets are simply the up and down legs of that cycle. A long bull market eventually reaches a peak, often when optimism and prices have run ahead of what the economy can support. From that peak, a bear market sets in as reality catches up and sentiment turns. The decline eventually reaches a low point, the trough, where pessimism is deepest and prices are cheapest. From there, often while the news still feels bleak, a new bull market quietly begins and the cycle repeats.

What drives the swings is a blend of two forces: the real economy and human emotion. Profits, interest rates and employment set the underlying direction, while fear and greed push prices to extremes in both directions. That emotional layer is exactly why markets overshoot on the way up and overshoot on the way down, and why trying to guess the precise turning points is so difficult. Our fear and greed index tracks this shift in mood day by day.

How Long They Last, and the Bigger Picture

There is no fixed timetable. Some bear markets are over in a few months, others grind on longer, and every cycle has its own character. The one pattern worth holding onto is this: across long stretches of market history, bull markets have tended to last considerably longer than bear markets, and the broad market has trended upward over time despite repeated downturns along the way.

This is the single most useful idea for a beginner. A bear market feels permanent while you are living through it, but historically it has been a temporary setback inside a much longer upward journey. The investors who have done well are rarely the ones who guessed the turns. They are the ones who kept their money invested, kept contributing, and let the long run trend do the heavy lifting. Past performance never guarantees the future, but the shape of that history is a powerful argument against panic.

What a Bull or Bear Market Means for You

Here is the part that actually matters for your money. In both phases, the most damaging thing a beginner can do is let emotion drive the decisions. In a bull market, that means resisting the urge to pour everything into whatever is soaring and to take wild risks because it feels easy. In a bear market, it means resisting the much stronger urge to sell in a panic and crystallise your losses.

A steadier approach works in either phase. Keep investing a regular amount on a schedule, which means you automatically buy fewer shares when prices are high and more when they are low. Stay broadly diversified rather than betting on a single hot idea. And measure your progress in years, not days, so a bad week does not derail a good plan. A bear market, viewed calmly, is not only survivable but is the time when your regular contributions buy the most.

How to Prepare Before a Bear Market Arrives

The best time to get ready for a bear market is long before one shows up, while you are calm and prices are high. Preparation is far more useful than prediction, because it does not require you to know when the next downturn will come, only that one eventually will. A few simple steps make the difference between riding a bear market out and being forced into a bad decision at the worst possible moment.

First, keep an emergency fund of cash separate from your investments, so that if you lose income during a downturn you never have to sell shares at low prices just to pay the bills. Second, hold a mix of investments you can actually stomach, since a portfolio that feels fine in a bull market but terrifies you in a bear market is the wrong portfolio for you. Third, automate your contributions, so that investing keeps happening on schedule even when fear makes you want to stop. Finally, write down your plan in advance, including exactly what you will do when prices fall, because a decision made calmly on paper is far better than one made in a panic. None of this stops a bear market from happening, but it turns one from a crisis into a manageable, and even useful, part of being an investor.

Common Mistakes People Make

The market phase is rarely the real problem. These four habits are what turn a normal cycle into a costly experience.

Panic selling in a bear market

Why it backfires: Selling after a big fall locks in the loss and often means missing the recovery, which can begin while the news still feels frightening.

Do this instead: Keep your regular contributions going and leave the holdings alone. Treat a bear market as a sale on shares, not a reason to flee.

Piling in at the top of a bull run

Why it backfires: Throwing extra money at whatever has risen most, just as optimism peaks, is how people buy at the worst prices right before a downturn.

Do this instead: Invest steadily on a schedule regardless of the mood, so you are never making one big bet at the top.

Trying to time the exact turn

Why it backfires: Guessing the precise peak or bottom is something even professionals fail at consistently, and being wrong is expensive in both directions.

Do this instead: Accept that you cannot time it. Staying invested through the cycle has beaten jumping in and out for most people.

Watching your balance every day

Why it backfires: Daily checking turns normal volatility into a stream of small frights that tempt you into needless, usually harmful, changes.

Do this instead: Check rarely. Automate your investing so good decisions happen without you staring at the screen.

Frequently asked questions

What is the difference between a bull market and a bear market?

A bull market is a sustained period of rising prices and optimism, while a bear market is a sustained fall of 20% or more from a recent high, usually with caution and fear. They are the two opposite phases of a normal market cycle.

What exactly counts as a bear market?

The common rule is a decline of 20% or more in a broad market index from its recent peak, sustained rather than a brief dip. A fall of 10% to 20% is usually called a correction, not a bear market.

How long do bear markets usually last?

There is no fixed length, but historically bear markets have tended to be shorter than bull markets, often measured in months rather than years. Every cycle is different, so the past is a guide rather than a promise.

Should I sell my investments in a bear market?

Selling in a bear market locks in your losses and can mean missing the recovery, which often begins before the news feels better. For most long term investors, staying invested and continuing to contribute has been the steadier approach.

Can you make money in a bear market?

For a long term investor, a bear market lets you buy at lower prices, so regular contributions buy more shares. Trying to profit directly from falling prices, through short selling or leveraged products, is risky and not suitable for beginners.

What causes a bull or bear market?

Both are driven by a mix of the economy and investor sentiment. Bull markets tend to align with growth, low unemployment and confidence, while bear markets often arrive with a slowing economy, rising unemployment and fear.
