In short: What bull and bear markets mean, how long they have tended to last, and how to stay steady in both.
You will hear two animals a lot in finance. Both describe the direction of the market.
Bull market
A bull market is a sustained rise in prices, often described as a rise of 20 percent or more from a recent low. Confidence is high and investors are optimistic.
Bear market
A bear market is commonly defined as a drop of 20 percent or more from a recent high. Fear rises and prices fall, sometimes for months.
They both end
Markets have moved through many bull and bear cycles over time. Past patterns do not guarantee future ones, but they show that neither lasts forever.
How to stay steady in a bear market
- Keep your emergency fund separate so you are not forced to sell.
- Stick with your plan and regular investing schedule.
- Do not make big decisions in a panic.
- Review companies for what has really changed, not what the price did.
How to stay steady in a bull market
Do not let rising prices push you into bigger positions than your plan allows. Excitement is when many people take too much risk.
The bigger point
Your plan should work in both. Build it on a calm day and follow it on every day.
Definitions
A bull market is a long period when stock prices rise broadly, often defined as a gain of 20 percent or more from a low. A bear market is a drop of 20 percent or more from a recent high. Corrections are smaller drops of 10 percent or more.
What causes them
Economic growth, interest rates, profits and investor mood all play a part. No one reliably predicts the turns.
How investors respond
Long-term investors keep investing through both. Bear markets can feel scary but have historically been followed by recoveries, though timing varies and nothing is guaranteed. Panic selling often locks in losses.
Prepare ahead
Build an emergency fund, size positions with limits and keep a plan. Regular buying through dollar cost averaging helps.
Frequently asked questions
Can I time the market?
Almost nobody does it consistently. Having a plan matters more.

The math of a drop and a recovery
One thing that surprises new investors is that losses and gains are not symmetrical. Say an index falls from 5,000 to 4,000. That is a 20% decline, which is the usual bear market line. To get back to 5,000, it needs to rise from 4,000, and that is a 25% gain, not 20%. The deeper the fall, the bigger the climb needed. A 50% drop needs a 100% gain to get even.
This is not meant to scare you. It explains why people care so much about steady habits and sensible position sizes. It also shows why selling after a big drop can feel so painful. The recovery needs to be bigger than the loss, and it takes time.
What a drop looks like in your own account
Numbers on a screen can feel abstract. Try it with dollars. If you hold $20,000 in a broad stock fund and the market has a 10% correction, your balance falls by about $2,000 to $18,000. In a 20% bear market, it falls by $4,000 to $16,000. If you add $300 a month during this period, those new dollars buy more shares at the lower prices. That is the thinking behind dollar cost averaging, and you can run your own numbers there.
Do bear markets and bull markets run on a clock?
No. Historically, bull markets have lasted longer than bear markets on average, and bear markets have often been shorter and sharper. But averages hide wide ranges. Some bear markets lasted a few months. Others lasted years. Nobody has a reliable way to call the start or end of either one. Be careful with anyone who claims they do.
Why it is hard in practice
In a bear market, news is loud and gloomy, and the urge to “do something” is strong. In a bull market, friends brag about gains, and the urge to add more is just as strong. Both urges are human. A written plan helps because you made it when you were calm. It might say how much you invest each month, what share of your money can sit in stocks, and when you will review things. Then you follow the plan rather than the headlines.
Common mistakes
- Selling everything after a 20% drop and then waiting for “the all clear,” which often comes after prices have risen.
- Putting in extra money at the top of a rally because it feels safe.
- Holding money you need within a year or two in stocks.
- Checking the account every day and treating small moves as signals.
What to do next
Look at your current mix of stocks and other holdings and ask a plain question. If stocks fell 30%, would I still be able to pay my bills and keep investing? If the honest answer is no, that is useful to learn before the drop, not during it. You can see how your holdings are split using the portfolio allocation calculator. For ideas on structure, read how to build a stock portfolio. The aim is a plan you can live with in both kinds of markets, not a perfect forecast.
Questions people ask about bull and bear markets
How long do bear markets last?
It varies. Some have lasted a few months and others more than a year or two. A common definition is a drop of 20 percent or more from a recent high. Past patterns do not tell us how any future decline will go.
Should I stop investing during a bear market?
That is a personal choice, and the answer depends on your goals, time frame and cash needs. Many long-term investors keep a steady plan, since stopping can mean missing recoveries. Money you need soon is usually kept out of stocks.
Can anyone tell when a bull or bear market starts?
Not reliably. Markets are usually labeled after the fact. Even professionals miss turning points. This is why many people rely on a written plan and diversification instead of trying to guess the next move.
Quick recap
Bull markets rise and bear markets fall, and both are a normal part of investing. No one can time them with confidence. A written plan, spread-out holdings and a realistic time frame can help you stay calm in either one.
