What is a Bull Market and Bear Market? Explained Simply
Bull vs bear market: A bull market is when stock prices rise 20%+ from a recent low. A bear market is when prices fall 20%+ from a recent high. Bull markets are significantly more common and longer than bear markets — the S&P 500 has spent approximately 75% of the past century in bull market conditions.
THE SPORTS SEASON ANALOGY
A bull market is a winning season — momentum is building, confidence is high, each week brings new highs. A bear market is a relegation battle — results are poor, morale is low, everyone doubts the team's future. But just as even great clubs have bad seasons, even the best economies have bear markets. The key is not panicking and selling the squad at the bottom of the table.

MAJOR BEAR MARKETS IN HISTORY
Dot-com crash (2000-2002): S&P 500 fell ~49%. Recovery: 7 years to new highs.
Financial crisis (2007-2009): S&P 500 fell ~57%. Recovery: 4 years.
The most important rule: do not sell in panic. Every bear market in history has been followed by a recovery to new highs. Selling at the bottom locks in permanent losses. Investors who continued buying during 2008-2009 and 2020 generated their best long-term returns.
Be fearful when others are greedy, and greedy when others are fearful. — Warren Buffett
FREQUENTLY ASKED QUESTIONS
How long does a bear market last?
The average bear market lasts approximately 9 months, though this varies widely. The 2020 COVID bear market lasted just 33 days. The 2000-2002 dot-com bear market lasted nearly 3 years. Bear markets associated with recessions tend to be longer and deeper than those caused by temporary shocks.
What causes a bear market?
Bear markets are typically caused by: economic recessions, rising interest rates reducing the present value of future earnings, bursting asset bubbles (like the dot-com or housing bubbles), major geopolitical shocks, or loss of investor confidence for psychological reasons. Often multiple causes combine.
Should I sell stocks in a bear market?
Historically, selling stocks during a bear market and waiting to reinvest has been worse than simply holding through. The challenge is that nobody knows when the bottom has been reached until after the recovery has begun. Research shows investors who stayed invested through bear markets consistently outperformed those who tried to time the exit and re-entry.
