Bull Market
Bull Market
Quick Definition
A bull market is a sustained period during which asset prices rise at least 20% from recent lows and are generally expected to continue rising. Bull markets are characterized by investor optimism, strong economic fundamentals, rising corporate earnings, and increased buying activity.
What It Means
The term "bull market" comes from the way a bull attacks, thrusting its horns upward, symbolizing rising prices. The opposite is a bear market (bear swipes downward with its paws).
A bull market is not a single good day or week. It is a prolonged upward trend that typically persists for months or years. While there is no official body that declares bull markets (unlike recessions, which the NBER dates), the conventional threshold is a 20% rise from the most recent bear market low.
Bull markets reflect a virtuous cycle: rising stock prices make investors feel wealthier, which encourages spending, which boosts corporate revenues, which lifts earnings, which justifies higher stock prices. This wealth effect and confidence loop can sustain bull markets for years.
The Current Bull Market: 2022 to Present
The bull market that began in late 2022 has been one of the strongest in nearly a century. According to Goldman Sachs, the S&P 500 has climbed roughly 95% since the bull market began near the end of 2022. Looking back to 1928, that places this rally within the top 10% of all bull markets at a comparable point in the cycle.
| Bull Market After Roughly 3.5 Years | S&P 500 Return |
|---|---|
| Median historical bull market | ~35% |
| Top 25% of historical bull markets | ~50% |
| Current bull market (2022-present) | ~95% |
What sets this bull market apart from speculative manias is that the gains have been driven by real earnings growth, not just valuation expansion. Goldman Sachs notes that much of the market's appreciation has come alongside improving profit expectations and heavy investment in AI infrastructure. Companies including Nvidia, Microsoft, Amazon, Meta, and Broadcom have translated AI enthusiasm into actual revenue growth, expanding cash flow, and record capital spending.
As of mid-July 2026, the S&P 500 holds a 22% year-to-date gain. The index has broadened beyond technology: the equal-weighted S&P 500 has outperformed the Nasdaq by 130 basis points during the recent tech pullback. Market breadth, measured by the percentage of S&P 500 stocks trading above their 200-day moving average, remains healthy at 68%, substantially higher than the 45% reading during periods of narrow leadership in early 2025.
Perhaps the most striking feature of this bull market is investor sentiment. Even with stocks up close to double digits in 2026, the AAII survey has shown more bears than bulls throughout the year. Sentiment is nowhere near euphoric. Historically, bull markets end when investors are exuberant, not when they are fearful. This "wall of worry" suggests the rally may have further to run.
Historical U.S. Bull Markets
| Bull Market Period | Duration | S&P 500 Gain | What Drove It |
|---|---|---|---|
| 1949-1956 | ~7 years | +267% | Post-WWII economic expansion |
| 1982-1987 | ~5 years | +229% | Volcker's inflation victory, tax cuts |
| 1990-2000 (dot-com era) | ~10 years | +417% | Technology revolution, deregulation |
| 2002-2007 | ~5 years | +101% | Housing boom, low rates |
| 2009-2020 | ~11 years | +401% | Longest on record; post-crisis recovery |
| 2020-2022 | ~2 years | +114% | COVID stimulus, tech dominance |
| 2022-present | Ongoing | +95%+ | AI boom, resilient economy, earnings growth |
The 2009-2020 bull market was the longest in modern U.S. stock market history, spanning nearly 11 years from the March 2009 bottom to the February 2020 COVID peak.
The Psychology of a Bull Market
Bull markets move through predictable psychological phases:
| Phase | Investor Sentiment | Market Signal |
|---|---|---|
| Disbelief | "This recovery can't last" | Early gains dismissed as temporary |
| Caution | "Maybe the worst is over" | Gradually increasing participation |
| Acceptance | "The economy is recovering" | Broad market participation |
| Optimism | "Things are looking great" | Strong momentum, new highs |
| Enthusiasm | "I'm missing out!" | FOMO buying, rising valuations |
| Euphoria | "Stocks only go up" | Dangerous peak; maximum risk |
The current bull market is notable for spending an unusually long time in the "disbelief" and "caution" phases. Even in mid-2026, with the S&P 500 up 95% from the lows, investor sentiment surveys show more bears than bulls. This persistent skepticism has historically been a bullish signal.
By the time most retail investors become enthusiastic about a bull market, the best gains have often already occurred. This is why "buying when everyone is fearful" has historically been more profitable than buying when everyone is excited.
Bull Market vs. Secular vs. Cyclical
| Type | Duration | What It Is |
|---|---|---|
| Secular bull market | 10-20+ years | Long-term structural uptrend; secular bull markets contain smaller bear markets within them |
| Cyclical bull market | Months to ~5 years | Shorter uptrend within a broader secular trend |
The 1982-2000 period is considered a secular bull market. The 2000-2009 period was a secular bear market (with two cyclical bear markets embedded). The post-2009 era has characteristics of a new secular bull market, and the current 2022-present rally may be a cyclical bull within that longer secular trend.
What Drives Bull Markets
| Driver | Mechanism |
|---|---|
| Low interest rates | Cheaper borrowing spurs investment; bonds less attractive vs. stocks |
| Strong earnings growth | Rising profits justify higher valuations |
| Economic expansion | GDP growth, low unemployment, high consumer confidence |
| Technological innovation | New industries create new wealth (railroads, electrification, internet, AI) |
| Easy monetary policy | Central bank stimulus via QE or low rates |
| Tax cuts | Higher after-tax earnings; more corporate buybacks |
| Global peace and stability | Reduced risk premiums |
In 2026, the drivers are primarily earnings growth and AI investment. The Federal Reserve has maintained rates at 3.5% to 3.75%, and inflation has re-accelerated to 4.1% due to the Middle East conflict. Despite these headwinds, corporate profits continue to grow. S&P 500 earnings rose 28% year over year in the first quarter of 2026, and analysts expect profit growth to exceed 20% for the full year, according to Fidelity.
Key Bull Market Statistics
| Metric | Average (Post-WWII) |
|---|---|
| Duration | ~4.5 years |
| Gain | ~152% |
| Longest ever | 11 years (2009-2020) |
| Largest gain ever | +417% (1990-2000 dot-com era) |
| Current bull market gain | ~95% (as of mid-2026) |
Bear markets, by contrast, average about 13 months and -36% in decline. This asymmetry, where bull markets last longer and gain more than bear markets last and lose, is why long-term investors are rewarded for staying invested.
Real-World Example: The 2009-2020 Bull Market
The longest bull market in U.S. history started on March 9, 2009, when the S&P 500 bottomed at 666.79.
- March 2009: S&P 500 = 666
- February 2020: S&P 500 = 3,386
- Gain: +408% over ~11 years
$10,000 invested at the March 2009 bottom grew to approximately $50,800 by the February 2020 peak.
The challenge: most investors did not buy at the bottom. The news in March 2009 was catastrophic (bank failures, 10% unemployment, housing collapse). The investor psychology was full fear. Those who stayed the course or bought in were richly rewarded.
Valuation Concerns in 2026
The current bull market has pushed valuations to elevated levels. The S&P 500 trades at roughly 20 times projected 2026 earnings, and the Shiller CAPE ratio sits near historical highs. The S&P 500's price-to-book ratio reached a record 5.63x in April 2026.
However, valuations look different from the dot-com era. At the peak of the late 1990s bubble, the largest technology firms in the S&P 500 traded at more than 125 times estimated earnings. Today's mega-cap technology leaders have substantial earnings growth to justify higher multiples. Capital expenditures among U.S. technology companies remain relatively low as a percentage of free cash flow, meaning they are funding investments from a position of strength rather than burning cash.
Rich valuations have historically translated into more modest future returns, even if they have not necessarily marked immediate market tops. The key question is whether earnings continue to grow fast enough to justify current prices.
Key Points to Remember
- A bull market is defined as a 20% rise from the most recent bear market low, sustained over months or years
- The current bull market (2022-present) has gained ~95%, placing it in the top 10% of all rallies since 1928
- Bull markets average ~4.5 years and ~152% gains in post-WWII history
- The 2009-2020 bull market was the longest in modern history at ~11 years
- Euphoria near market peaks is a warning sign, not a buying signal
- Investor sentiment remains cautious in 2026 despite strong gains, which historically suggests room to run
- Long-term investors benefit most from bull markets by staying invested rather than timing entries and exits
Common Mistakes to Avoid
- Becoming overconfident during prolonged bull markets: Extended bull markets can lead investors to take excessive risk, take on too much debt, or abandon diversification.
- Confusing a bull market with investment skill: In a strong bull market, nearly everything rises. True skill shows in bear markets. Read our guide on dollar-cost averaging for a strategy that works regardless of market direction.
- Holding too much cash waiting for a pullback: "Waiting for a correction to buy" often means missing significant gains. In 2026, investors who waited for a pullback missed a 22% year-to-date gain.
- Ignoring valuation: Even in a bull market driven by earnings, paying 20x or 30x earnings means future returns may be modest. Understand the P/E ratio of what you are buying.
- Chasing the hottest sector: The current bull market has seen sharp rotations. Semiconductor stocks fell 11% in July 2026 while bank stocks rose 8%. Chasing last month's winner often means buying at the top.
Frequently Asked Questions
Q: How do you know when a bull market starts? A: Only in retrospect. A 20% gain from a recent low confirms the bull market started at that low. In real time, it is impossible to know with certainty whether a market bounce is the start of a new bull market or a temporary recovery within a bear market.
Q: Can a bull market happen in bonds too? A: Yes. The 1981-2020 period was a four-decade bull market in bonds, as interest rates fell from ~15% to near 0%, driving bond prices up continuously. Rising rates since 2022 have reversed this trend, and the bond market has been in a bear market since mid-2020. See our bond definition for more.
Q: What typically ends a bull market? A: Rising interest rates (which increase the cost of capital and reduce the present value of future earnings), recession, external shocks (pandemic, war, financial crisis), or excessive valuations that can no longer be sustained by earnings growth.
Q: Is the current bull market a bubble? A: According to Goldman Sachs and Fidelity, the current rally is supported by real earnings growth rather than speculative excess. S&P 500 earnings rose 28% year over year in Q1 2026. Valuations are elevated by historical standards but below dot-com era extremes. However, rich valuations historically lead to more modest future returns, even if they do not signal an immediate top.
Q: Should I invest now or wait for a dip? A: Historically, time in the market beats timing the market. The current bull market has gained 95% from its lows. Investors who waited for a pullback have missed those gains. A strategy of regular investments (dollar-cost averaging) removes the need to time the market. Use our investment return calculator to model different scenarios.
