What Is a Bull Market?

A bull market is a period in which prices rise over a sustained stretch, usually with improving earnings, growing economic activity and rising investor confidence. The word comes from the way a bull thrusts its horns upward. A bull run can last months or years, with small pullbacks along the way.

What Is a Bear Market?

A bear market is a sustained fall, commonly defined as a drop of 20% or more from a recent peak. The word comes from the way a bear swipes its paws downward. Bear phases are usually linked to weak growth, tight liquidity, high interest rates or loss of confidence.

Bull Market vs Bear Market: Key Differences

Feature	Bull market	Bear market
Direction	Rising prices	Falling prices
Sentiment	Optimism, rising risk appetite	Fear, falling risk appetite
Typical drivers	Earnings growth, easy money	Slowdown, rate pressure, shocks
Typical size	Large cumulative gains	Fall of about 20% or more
Investor behaviour	Fear of missing out	Panic selling or waiting

Where Does a Correction Fit?

A correction is a smaller fall, commonly around 10% from a recent high. Corrections happen often within bull markets and are part of healthy price discovery. They can be a profit booking phase after a long rise. If a correction deepens and stays low for long, it may turn into a bear phase.

A 10% fall is usually called a correction, and a 20% fall is the usual line for a bear market. A market correction rarely ends a bull run, because a market correction clears excess optimism and the market cycle then resumes. Economic growth, earnings and rates shape each market cycle, and a bull run needs all three to stay supportive.

How Long Do These Phases Last?

There is no fixed duration. Historically, bull markets have lasted longer than bear markets, and bear markets have usually ended faster than they began. But every cycle is different, and nobody can reliably call the top or the bottom in advance.

How Investors Can Respond

• Keep a SIP running in both phases, so you buy more units when prices are lower.
• Match asset allocation to your goals and rebalance when it drifts.
• Avoid putting all your money in at a market high or selling everything in panic.
• Keep an emergency fund so you do not have to sell in a downturn.
• Review quality, debt and valuation of holdings in all conditions.

Watching the broad market through an index such as the Sensex helps you see the phase, but your own goals and time horizon should guide what you do.

Common Mistakes

Many investors enter near the peak of a bull run because of fear of missing out, then sell in a bear phase because of fear. Others wait for the perfect bottom and miss the recovery. A written plan, regular investing and sensible diversification reduce the damage from both mistakes.

Keep a simple journal of what you did in each phase and why. Over a few years, the notes show whether you tend to buy on excitement or sell on worry, and that self-knowledge is often worth more than any forecast. Write down the amount you invested, the date and the reason, and review the journal once every quarter.

Frequently Asked Questions

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

Ans. A bull market is a sustained rise in prices with optimism, and a bear market is a sustained fall, commonly defined as a decline of about 20% or more from a peak. They are the two broad phases of the market cycle.

What is a market correction?

Ans. A correction is a smaller fall, commonly around 10% from a recent high. It often happens within a bull market and is seen as a healthy pause after a strong rise.

How long does a bear market last?

Ans. There is no fixed length. Bear markets have usually been shorter than bull markets, but each cycle differs. Trying to time the exact bottom is difficult even for professionals.

Should I stop my SIP in a bear market?

Ans. Usually not. A SIP buys more units when prices are lower, which can improve the average cost over time. Stopping it may be reasonable only if your income or goals have changed.

Is it a good time to invest in a bear market?

Ans. Lower prices can offer better entry points, but there is no certainty about how far prices will fall. Staggered investing and a long horizon help reduce the timing risk.

What causes a bull market?

Ans. Common drivers include strong earnings growth, stable or falling interest rates, easy liquidity and growing confidence. They often work together, but no single factor guarantees it.

Can I predict the next bull or bear market?

Ans. Not reliably. Many signals exist, but none works every time. A plan based on goals, risk tolerance and diversification is more dependable than predictions.
