What Is a Bear Market?
A bear market is a prolonged period of falling prices accompanied by deteriorating sentiment, usually declared when a broad index closes 20 percent or more below its recent peak. It is more severe than a correction, which is a decline of 10 to 20 percent.
The name reflects the bear's downward swipe, the opposite of the bull's upward thrust. Bear markets often overlap with recessions, but not always; markets can fall 20 percent on rate shocks, bubbles deflating, or crises even while the broader economy keeps growing.
How Bear Markets Behave
Bear markets tend to be shorter and sharper than bull markets, historically lasting on the order of a year or so versus multi-year expansions. Declines are punctuated by violent rallies, sometimes called bear market rallies, that lure investors back in before prices roll over again.
Selling pressure feeds on itself as margin calls force liquidations, funds face redemptions, and volatility spikes. Bottoms usually form when valuations are depressed and the news is still bleak, which is precisely when buying feels hardest.
Example
Suppose an index peaks at 5,000 and slides to 4,000, a 20 percent decline that officially marks a bear market. A portfolio worth 100,000 dollars at the top would be down to 80,000 dollars, and if the slide deepens to 35 percent, to 65,000 dollars.
Recovery math is unforgiving: a 35 percent loss requires roughly a 54 percent gain just to break even, since 65,000 x 1.54 is about 100,000. This asymmetry is why risk management and diversification matter so much before the decline starts.
Why It Matters
Bear markets transfer wealth from forced sellers to patient buyers, and for long-horizon investors they are historically the best moments to deploy capital. They also reshape the industry itself, freezing IPO markets, slowing M&A, and triggering layoffs across banking and asset management.
For traders and analysts, bear markets are where short selling, hedging, and credit analysis earn their keep, and navigating one early in a career is a formative professional experience.
