Understanding the rhythm of financial markets is essential for any investor—whether active in public equities or private ventures. The terms bear market and bull market are more than just Wall Street jargon; they represent powerful phases in the economic cycle that influence everything from stock prices to consumer confidence. In this guide, we’ll break down the core differences between bear and bull markets, explore their causes and effects, and examine how these cycles impact both public and private investors.

Market Cycles Explained
Financial markets don’t move in straight lines—they ebb and flow in cycles. These cycles are broadly categorized into two types: secular and cyclical.
- Secular market cycles span long periods, typically lasting 10 to 20 years. Within a long-term bull market, for example, there can be shorter downturns or corrections that resemble bearish conditions—but the overall trend remains upward.
- Cyclical market cycles, on the other hand, are shorter in duration, lasting from a few weeks to several months. These are often driven by immediate economic data, policy changes, or global events.
Historically, bull markets tend to last longer than bear markets. On average, a bull market persists for about 3.8 years, while a bear market lasts approximately 289 days (just under 10 months). This asymmetry reflects the general long-term growth trajectory of economies, even amid periodic setbacks.
The 20% Rule: Defining Bull and Bear Markets
A widely accepted benchmark for identifying these market phases is the 20% rule:
- A bear market is confirmed when major stock indexes—such as the S&P 500 or Dow Jones Industrial Average—decline by more than 20% from recent highs.
- A bull market is declared when those same indexes rise over 20% from their most recent lows.
This threshold helps distinguish between temporary corrections (typically 10% drops) and full-fledged shifts in market direction.
What Defines a Bear Market?
Characteristics of a Bear Market
A bear market signals a prolonged period of declining investor confidence and economic weakness. Key indicators include:
- Sustained drop in stock prices
- Rising unemployment
- High inflation or erratic price swings
- Increasing interest rates
- Reduced consumer spending
Even before hitting the official 20% threshold, markets may exhibit “bearish” sentiment—reflecting growing pessimism among investors and analysts.
Causes of a Bear Market
Bear markets rarely stem from a single cause. Instead, they often result from a combination of macroeconomic shocks, such as:
- Geopolitical conflicts
- Pandemics
- Bursting financial bubbles
- Tight monetary policy
One notable example occurred at the onset of the COVID-19 pandemic. Research indicates that the U.S. entered a bear market on February 26, 2020, triggered by widespread economic disruptions—13 days before the World Health Organization officially classified it as a global pandemic.
Results of a Bear Market
During bear markets, investor behavior shifts dramatically:
- Panic selling in public markets
- Liquidity crunches
- Business closures and layoffs
- Declining asset valuations
Consumers also feel the impact through higher grocery prices, reduced job security, and tighter credit conditions.
What Defines a Bull Market?
Characteristics of a Bull Market
In contrast, a bull market reflects optimism and expansion. Key traits include:
- Rising stock prices across sectors
- Falling unemployment
- Stable or low inflation
- Positive investor sentiment
- Strong corporate earnings
These conditions often encourage risk-taking and increased investment activity.
Causes of a Bull Market
Bull markets can emerge from policy interventions (like interest rate cuts), technological innovation, or recovery from previous downturns. Sometimes, the causes and effects reinforce each other: rising prices boost confidence, which drives further investment—a self-sustaining cycle.
For instance, after the 2020 bear market, aggressive fiscal stimulus and vaccine rollouts helped reignite growth. By mid-2023, the S&P 500 had climbed more than 20% from its October 2022 low—officially marking the start of a new bull phase.
Bear Rally: A Temporary Uptick
A bear rally refers to a short-term upward movement within an ongoing bear market. It can mimic early signs of recovery but doesn’t signal a sustained turnaround. During the 2020 crisis, markets experienced such rallies—brief rebounds amid continued uncertainty—before stabilizing into a true bull trend.
Are We in a Bull Market Now?
As of late 2024, many analysts believe we are still within a bull market that began in late 2022. Several indicators support this view:
- Annual inflation has cooled to 2.5%, the lowest since early 2021
- The Federal Reserve cut interest rates by 0.5 percentage points in September 2024—the first cut since the pandemic began
- Labor markets, while showing signs of softening, remain resilient
These moves aim to sustain economic momentum without triggering overheating. However, prices remain 21.2% higher than pre-pandemic levels in February 2020, underscoring lingering inflationary pressures.

Impact on Private Market Investors
While private market investors aren’t directly exposed to daily stock swings, they’re not immune to broader trends.
In bear markets, capital becomes scarcer. Investors may pull back from new commitments and seek liquidity through secondary sales—potentially creating discounted entry points for savvy buyers.
Conversely, bull markets often fuel startup valuations and IPO activity. With abundant capital flowing into venture ecosystems, companies may delay going public or raise larger funding rounds at higher multiples.
