Bull Market vs Bear Market: How to Tell Which One You’re In

The short version: a bull market means prices are broadly rising, and confidence is high. A bear market means prices have fallen sharply, usually 20% or more from a recent peak, and pessimism dominates. Here’s how to actually recognise which one you’re in.

The technical definitions

Analysts generally call it a bear market once a broad index falls 20% or more from its recent high. A bull market is the opposite — a sustained rise, usually also measured from a prior low, without a strict percentage threshold.

These definitions are useful, but they’re backward-looking. By the time a 20% drop is confirmed, a lot of the damage is already done. That’s why sentiment and momentum indicators matter too, not just the raw percentage.

What actually distinguishes the two, beyond price

Bull markets tend to feature rising trading volumes on up days, improving corporate earnings, and generally optimistic news coverage. Investors are willing to pay higher prices for the same future earnings.

Bear markets often show the opposite: falling volumes on rallies, deteriorating earnings outlooks, and a general unwillingness to take risk. Even good news tends to get a muted market reaction during a bear phase.

Why the difference matters for your decisions

In a bull market, the temptation is to chase momentum, and pile into whatever’s rallying hardest. That can work for a while, but it also means paying the highest prices right before a possible turn.

In a bear market, the temptation is to panic-sell near the bottom, locking in losses just before conditions eventually improve. Both instincts push you toward buying high and selling low, which is the opposite of what actually builds wealth.

How long do these phases usually last?

Bull markets have historically lasted considerably longer than bear markets, often for years. Bear markets, while sharper and more painful, have tended to be shorter, frequently resolving within a year or two.

This asymmetry is a big part of why staying invested through downturns, rather than trying to perfectly time an exit and re-entry, has historically rewarded patient investors more than it’s punished them.

A practical way to think about it

Rather than trying to precisely call the top or bottom, focus on your own asset allocation and time horizon. If your goals and risk tolerance haven’t changed, a bear market is rarely a reason to abandon a sound long-term plan.

Frequently asked questions

What percentage drop officially defines a bear market?

Analysts generally use a 20% or greater decline from a recent high as the threshold for calling a downturn a bear market.

How long do bear markets usually last?

Historically, bear markets have tended to be shorter than bull markets, often resolving within a year or two, though every cycle differs.

Is it a good idea to sell everything during a bear market?

Most advisors caution against this, since panic-selling near a bottom locks in losses right before conditions have historically tended to improve.

Can you have a bull market in some sectors and a bear market in others?

Yes — this is common, and it’s why looking at a single broad index can sometimes miss meaningful divergence across sectors.

What’s the best way to prepare for the next bear market?

Having a clear asset allocation matched to your goals and risk tolerance ahead of time, rather than reacting emotionally once a downturn starts.
