You’re staring at a red screen. Everything is down. Your portfolio looks like a crime scene, and suddenly, everyone on the news is talking about "bears." Then, three months later, the green bars return, people are shouting about "bulls" on Twitter, and you're left wondering if the financial world just really likes forest animals.
It's messy.
Basically, the bear market vs bull market definition comes down to direction and sentiment, but it’s never as clean as the textbook says. You’ve probably heard the 20% rule. If the market drops 20% from its recent peak, it's a bear. If it rises 20% from the lows, it's a bull. Simple, right? Honestly, it's more about the vibe and the underlying economy than just a specific number on a spreadsheet.
The Bull Market: Running on adrenaline and cheap debt
Think of a bull. It attacks by thrusting its horns upward. That’s the visual you need. A bull market is characterized by rising prices, investor optimism, and a general belief that the "good times" are going to keep rolling.
Money is easy to find.
Companies are hiring, people are spending, and even your cousin who knows nothing about finance is suddenly a "pro trader." We saw a massive example of this during the post-2008 recovery, which became the longest bull market in American history, lasting until the 2020 COVID crash. During that decade-plus run, the S&P 500 grew by over 400%. It wasn't just a slow climb; it was a sustained period where every "dip" in the stock price was seen as a buying opportunity.
People get greedy here.
In a bull market, the psychological "fear of missing out" (FOMO) takes over. You see Tesla or Nvidia skyrocketing, and even if the valuation makes zero sense based on actual earnings, people keep buying because they expect the price to be higher tomorrow. This creates a feedback loop. High demand leads to higher prices, which leads to more media coverage, which leads to even more demand.
But bull markets aren't just about stocks. They usually coincide with a strong Gross Domestic Product (GDP) and low unemployment. When people feel secure in their jobs, they put more money into their 401(k)s. This constant inflow of cash acts like fuel for the fire.

When the Bear Wakes Up: Fear, loathing, and the 20% cliff
Now, picture the bear. It swipes its paws downward.
A bear market is the grim reaper of Wall Street. Formally, it’s a 20% drop, but it feels like a slow, agonizing slide into the basement. If a bull market is a party, a bear market is the 3:00 AM hangover when the lights come on and you realize you spent too much money.
Investors get terrified.
They stop looking at their accounts. They sell their "risky" assets and move into cash or gold. This is what we call "risk-off" behavior. The 2022 bear market is a prime example. Inflation started ripping, the Federal Reserve began hiking interest rates, and suddenly, those high-flying tech stocks that looked like geniuses in 2021 were falling 50%, 60%, or even 80%.
Bear markets are actually much shorter than bull markets on average. Since World War II, the average bear market has lasted about 289 days, or roughly 10 months. Compare that to the average bull market, which sticks around for nearly three years.
It feels longer, though.
The psychological pain of losing money is twice as powerful as the joy of gaining it. Psychologists call this "loss aversion." Because of this, bear markets are filled with "relief rallies" or "dead cat bounces." This is when the market jumps up 5% in a week, making everyone think the bottom is in, only for it to crash to new lows the following Monday. It’s exhausting.
Why the distinction actually matters for your wallet
If you’re just "indexing and chilling," the bear market vs bull market definition might seem like academic noise. But for anyone trying to manage their own risk, the differences dictate your entire strategy.

In a bull market, "growth" is the king. You want the companies that are expanding fast, even if they aren't profitable yet. You’re looking for capital appreciation. You want to be aggressive because the wind is at your back.
When the bear takes over, "value" and "defensive" stocks become the heroes. People flock to boring companies—the ones that sell toilet paper, electricity, and canned soup. Think Procter & Gamble or Duke Energy. These companies don't grow 50% a year, but they don't disappear when the economy hits a wall, either.
Key differences at a glance
- Market Sentiment: Bulls are driven by optimism and greed; bears are driven by fear and pessimism.
- Economic Indicators: Bull markets usually see high GDP and low unemployment. Bear markets often precede or accompany recessions.
- Price Action: Bulls feature "higher highs" and "higher lows." Bears feature "lower highs" and "lower lows."
- Duration: Bulls are marathons. Bears are short, violent sprints to the bottom.
The "Gray Area" nobody likes to talk about
Sometimes the market isn't a bull or a bear. It's a "sideways" market, often called a kangaroo market because it just bounces up and down without going anywhere.
You also have "corrections."
A correction is a 10% drop. It’s not quite a bear market, but it’s a healthy—albeit painful—pullback that keeps the bull market from getting too overheated. Think of it like a safety valve. If markets only went up, bubbles would form every single year. Corrections pop the tiny bubbles before they become systemic disasters.
Then there’s the "secular" vs. "cyclical" distinction. A secular bull market can last 20 years, even if it has a few small bear markets tucked inside it. It’s the long-term trend. Understanding where we are in the secular cycle is arguably more important than worrying about the headlines this week.
Real-world evidence: The 1970s vs. the 1990s
To really get the bear market vs bull market definition, you have to look at history.
The 1970s were a secular bear market. Between 1966 and 1982, the Dow Jones Industrial Average basically went nowhere. It would rally, then crash, then rally, then crash. Inflation was eating everyone alive. Even though there were "bullish" years in there, the overall era was bearish because the real value of stocks was declining.

Contrast that with the 1990s. That was a classic secular bull. The internet was being born. Productivity was exploding. You could have thrown a dart at a list of stocks and made 20% that year. It was a period of unbridled optimism that didn't end until the Dot-com bubble finally burst in March 2000.
Surviving the cycle: Actionable steps
You can't control the market, but you can control your reaction to it. Most people lose money because they buy at the top of a bull market (greed) and sell at the bottom of a bear market (fear). That is the literal opposite of what you should do.
1. Rebalance when things are good.
When the bull market has been running for three years and your stock portfolio has grown from 60% of your net worth to 80%, sell some. Move it into bonds or cash. This isn't "timing the market"; it's maintaining your risk profile.
2. Have a "Bear Market Fund."
This isn't your emergency fund for a broken water heater. This is a pile of cash sitting on the sidelines specifically to buy stocks when they are 20% off. When everyone else is panicking, you want to be the one with the dry powder.
3. Ignore the "Perma-Bears."
There are people who have predicted 50 of the last two recessions. They are always bearish. While they sound smart, they usually miss out on the massive gains of the bull cycles. Betting against human ingenuity and economic growth is a losing game over the long term.
4. Check your time horizon.
If you need your money in two years, a bear market is a catastrophe. If you need your money in twenty years, a bear market is a gift. It allows you to accumulate more shares at a lower cost-basis.
5. Diversify beyond the S&P 500.
Sometimes US stocks are in a bear market while international stocks or commodities are in a bull market. Don't put all your eggs in one geographic basket.
The reality is that these cycles are inevitable. They are the breathing of the financial system. Inhale (bull), exhale (bear). You can't have one without the other. The goal isn't to avoid the bear; it's to survive it so you're still standing when the bull eventually returns.
Next Steps for Your Portfolio
- Audit your current asset allocation: Determine if your recent gains have made your portfolio too "top-heavy" in risky stocks.
- Set "Buy Triggers": Decide now—while you are calm—at what percentage drop you will move extra cash into the market.
- Review your fixed-income holdings: Ensure you have enough liquidity to last 12-18 months without selling stocks if a bear market starts tomorrow.
