The difference is direction: a bull market is a sustained period of rising prices and optimism, while a bear market is a sustained period of falling prices, commonly defined as a drop of roughly 20 percent or more from a recent high. Both describe a trend over weeks or months, not a single noisy day. They are normal, recurring phases of the market cycle, and every bull has eventually given way to a bear and vice versa. This is general education, not personalized advice, so confirm your own circumstances before making decisions.
How each is defined
A bull market does not have one rigid threshold; it is generally understood as a broad, lasting upward trend. A bear market has a rougher rule of thumb: a decline of about 20 percent or more from a recent peak in a major index. A smaller dip, often around 10 percent, is usually called a correction rather than a bear.
The names come from how each animal attacks: a bull thrusts its horns upward, a bear swipes its paws down.

What drives the switch
Bull markets are usually fed by growing earnings, confidence, and demand for shares. Bears are typically triggered by some mix of slowing growth, rising fears, shocks, or stretched valuations unwinding. The exact cause differs every cycle, which is precisely why predicting the turn is so hard. For beginners, it helps to first understand how to invest in stocks before worrying about timing cycles at all.
How long-term investors should respond
- Decide your plan before a downturn arrives, when you can think clearly.
- In a bull market, avoid assuming gains continue forever; rebalance if one area grows out of proportion.
- In a bear market, resist panic selling, which locks in losses; downturns have historically recovered over time.
- Keep an emergency fund separate so you are not forced to sell investments at a low point.
What to skip
- Skip trying to call the exact top or bottom. Even professionals rarely time it, and missing a few of the best rebound days can hurt long-run returns.
- Skip making big, emotional bets based on headlines. Sentiment is loudest right when it is least reliable.
- Skip checking your balance obsessively in a bear market; it tends to amplify fear without improving decisions.
FAQ
How much does the market have to fall to be a bear market?
The common rule of thumb is a decline of about 20 percent or more from a recent peak. A smaller drop, around 10 percent, is usually called a correction.
How long do bull and bear markets last?
It varies widely. Historically bull markets have tended to last longer than bear markets, but there is no fixed schedule and past patterns do not guarantee the future.
Should I sell everything in a bear market?
For long-term goals, selling in a panic locks in losses and risks missing the recovery. Many investors do better sticking to a plan, but your own situation matters.
Can a bull and bear market happen in different assets at once?
Yes. Stocks, bonds, and other assets can move in different directions, which is one reason diversification helps.
