Bear Markets vs. Bull Markets: Key Differences Explained

Bull markets and bear markets describe the two primary directional phases of a stock market cycle. A bull market is a sustained period of rising stock prices, while a bear market is a deeper, fundamentally driven market decline, commonly associated with a drop of approximately 20% or more from a prior high.

While bull and bear markets are normal parts of investing, they can create very different market conditions and emotional pressures for investors.

Understanding the difference between a bull market and a bear market can help investors place short-term market volatility in context without assuming every decline or rally indicates a lasting change in direction. In this article, we explain what bull and bear markets are, compare their key differences, review common causes, and discuss what each phase may mean for long-term investors.

What Is the Difference Between a Bull Market and a Bear Market?

The basic difference between a bull market and a bear market is the direction of stock prices.

A bull market is a prolonged period—often years—when stock prices trend upward. A bear market is a sustained decline in stock prices, typically driven by deteriorating fundamentals such as weak corporate earnings or slowing economic activity. While a drop of 20% from a previous market high is a common threshold, the percentage alone does not explain the cause or duration of the decline.

However, neither bull markets nor bear markets move in a straight line. Bull markets can include pullbacks, corrections and periods of sharp negative volatility along the way. Similarly, bear markets may include short rallies while trending downward overall. Short-term volatility is expected in stock markets and does not necessarily signal a broader market cycle change.

What Are the Characteristics of a Bull Market?

While bull markets are associated with a sustained upward trend in the stock market, they have other characteristics that are important for investors to understand. One important characteristic of bull markets is that they do not rise in a straight line. Short-term volatility, including pullbacks and corrections, can occur without ending the broader bull market. Pullbacks are sentiment-driven declines of 5% to 10% and are relatively common within a bull market. A correction is generally a short, steep, sentiment-driven market downturn of around 10% to 20%, while a bear market is a deeper, more extended decline typically tied to deteriorating fundamentals.

Common bull market characteristics include:

A bull market can begin before economic conditions appear strong. Because stock prices are forward-looking, the market may start rising during periods of pessimistic sentiment, as reality turns out better than investors feared. An economic recovery, stronger consumer spending or improving corporate earnings can help reinforce the bull market as it matures.

Market leadership can also shift between different styles, sectors and countries. For example, growth stocks or Tech stocks may lead during one period, while value or defensive stocks may lead later. These leadership shifts, along with short-term volatility, are part and parcel of a bull market. By themselves, they do not indicate a bull market is ending.

What Are the Characteristics of a Bear Market?

Bear markets can be understandably unsettling for investors because they are market declines of at least 20% from prior peaks. But what should investors know about bear market characteristics, and how can that knowledge help them better understand these downturns?

When it comes to bear markets, investors should understand that unlike corrections, which typically feature sharp, steep drops, bear markets often start gradually, with the worst declines usually coming late.

Weakening economic activity and deteriorating corporate profits amid euphoric investor sentiment—or an unforeseen event capable of causing broad, deep economic harm—are common causes of bear markets. Investor confidence often declines as losses accumulate, and negative market sentiment can add to short-term selling pressure.

Common bear market characteristics include:

A bear market is not the same as a recession. A recession describes a broad contraction in economic activity, while a bear market describes a deep decline in asset prices. They can overlap, but the stock market tends to move before backward-looking economic data confirm a change.

Bear markets can also include sharp rallies that are usually driven by investor sentiment rather than improving fundamentals. These increases may be substantial, but they do not necessarily change the broader downward market trend and can create a head fake for investors anticipating a market recovery. This is one reason investors can struggle to identify the beginning or end of a bear phase in real time.

What Causes Bull Markets and Bear Markets?

At Fisher Investments, we evaluate three broad market drivers: economics, politics and sentiment. These forces interact, and markets often respond to the difference between expectations and reality rather than whether a development appears positive or negative in isolation.

A bull market typically begins while expectations are low. Investors may remain pessimistic after a prior downturn, but stock prices can rise if economic and/or political conditions prove less negative than feared. As the market advances, economic expansion, corporate earnings growth and improving investor confidence can support further gains.

A bear market can begin when fundamentals deteriorate relative to exceedingly high investor expectations to the point that reality can no longer keep pace. High asset prices or strong sentiment alone do not cause a bear market, but they can make the market more sensitive to disappointing results.

Strong economic data can disappoint if investors expected more. Weak data can support stock prices if conditions are better than feared. This expectations-versus-reality gap helps explain why market behavior does not always match current headlines.

Bear markets can also begin when a large, unexpected shock strikes the broader economy. These “wallops” would need to be both unexpected and powerful enough to remove several trillion dollars from global economic output. Causes of wallops can include severe government policy errors, major global conflicts or sudden decisions that shut down large portions of the economy. Most risks perceived as having wallop potential do not meet the scale or surprise factor required to cause a bear market on their own.

How Long Do Bull Markets and Bear Markets Last?

There is no set duration for either bull or bear markets, but there are historical trends we can use as references. Historically, bull markets have tended to last longer than bear markets. In fact, since 1946, bull markets have, on average, lasted 61 months, while bear markets have had an average duration of 14 months during the same period.^[i]

Some investors look to these averages to see if they can predict when a bull or bear market may be reaching its end. But market age alone does not determine when this turning point will arrive. Selling because a bull run appears old can mean missing additional gains. Those bull market gains are often vital for an investor trying to reach their long-term goals and objectives.

Conversely, waiting for a bear market to feel clearly in the rearview mirror can mean returning after stock prices have already experienced a good chunk of their recovery. So, while historical averages can help investors understand how past bull and bear markets behaved, averages alone aren’t predictive of how the current or next market phase may unfold.

Bull and Bear Markets in the Market Cycle

Bull markets and bear markets are the two broad directional phases of the stock market cycle. Investor sentiment typically changes as the market cycle progresses.

Legendary investor Sir John Templeton famously described this progression by saying, “Bull markets are born on pessimism, grow on skepticism, mature on optimism and die on euphoria.” Early in a bull market, investors may remain focused on the prior bear market. As stock prices rise, skepticism can gradually shift toward optimism and greater confidence.

Near the later stages of a bull market, euphoria can make investors less attentive to rising risk or deteriorating fundamentals. If fundamentals deteriorate or a major unforeseen event causes economic damage, a bear market may follow. Pessimism can then deepen as prices fall.

This framework describes common patterns, but not a market-timing formula. For example, euphoric sentiment can last for years and does not, in and of itself, signal a bear market is imminent. Turning points in both bull and bear markets, along with those shifts in investor sentiment, are often obvious only after they occur.

What Bull and Bear Markets Mean for Investors

Bull and bear markets create different behavioral risks that investors should be aware of. During a bull market, rising prices may encourage investors to chase popular assets or take more risk than may be prudent within their long-term investment strategy. These instances of greed, or “heat chasing,” can be counterproductive to an investor reaching their long-term goals.

During a bear market, falling prices may prompt investors to sell after losses have already occurred. Exiting the market creates a second, potentially costly decision: when to return. Waiting for economic conditions or investor confidence to improve can mean missing strong gains from an early recovery because the stock market often begins to improve before sentiment does.

Instead of solely reacting to market developments to guide their strategy, in our view, investors are better served evaluating how to adjust to market conditions within the context of their long-term goals, risk tolerance and investment time horizon. That does not mean ignoring market developments. It means avoiding investment decisions based primarily on short-term price movement, headlines or emotion.

Long-term stock returns come with the risk of market declines, but the truth remains that historically, bull markets have been longer and stronger than bear markets—something that benefits disciplined, long-term investors. Understanding the importance of discipline, along with bull and bear market phases, can help investors interpret price movement without assuming every rally or decline requires a change in strategy.
