Bull vs Bear Market — Understanding Market Cycles

Definition

A bull market is a period of sustained rising asset prices, typically defined as a 20% or greater increase from recent lows, accompanied by widespread investor optimism and strong economic fundamentals. A bear market is the opposite — a decline of 20% or more from recent highs, marked by pessimism and often economic weakness.

These are not precise scientific terms but rather widely adopted conventions that help investors communicate about market conditions.

How It Works

The Classification Framework

Market Condition          Typical Threshold     Duration
────────────────          ─────────────────     ────────
Pullback/Dip              −5% to −10%          Days to weeks
Correction                −10% to −20%         Weeks to months
Bear market               −20% or more         Months to years
Bull market               +20% from low        Months to years
Secular bull/bear          Multi-year trend     5-20 years

Characteristics Compared

Historical Context

S&P 500 bear markets since 2000:

• 2000-2002 (Dot-com): −49%, lasted 30 months
• 2007-2009 (GFC): −57%, lasted 17 months
• 2020 (COVID): −34%, lasted 1 month (fastest recovery ever)
• 2022 (Inflation/rates): −25%, lasted 10 months

WIG20 bear markets:

• 2007-2009: −68% (deeper than S&P 500 due to emerging market sell-off)
• 2020 (COVID): −38%
• 2022: −30%

Average bull market duration (S&P 500): ~5.5 years Average bear market duration (S&P 500): ~13 months

The asymmetry is important: bulls last much longer than bears, which is why the market trends upward over time.

Example

A Polish investor started with 200,000 PLN in a global equity ETF (VWCE) in January 2020. Here is what happened through a full bear-and-bull cycle:

Jan 2020:  200,000 PLN (starting value)
Mar 2020:  132,000 PLN (−34%, COVID bear market bottom)
Dec 2020:  220,000 PLN (+67% from bottom, +10% from start)
Dec 2021:  290,000 PLN (+45% total from start)
Oct 2022:  225,000 PLN (−22% from peak, 2022 bear)
Dec 2023:  310,000 PLN (new all-time high)
Dec 2025:  380,000 PLN (+90% total from start, +188% from 2020 bottom)

Key takeaways from this real-world sequence:

1. Staying invested through the 2020 bear turned −34% into +90% over 6 years
2. Selling at the March 2020 bottom and waiting for "stability" would have missed the fastest recovery in history
3. The 2022 bear was slower and more psychologically grinding — no V-shaped recovery
4. Time in the market beat timing the market

The Cost of Missing the Best Days

If the investor panicked and went to cash during the 2020 crash, missing just the 10 best trading days:

Fully invested 2020-2025: +90% (380,000 PLN)
Missing best 10 days: approximately +35% (270,000 PLN)
Cost of panic: ~110,000 PLN

Research consistently shows that the best market days often occur during bear markets, clustered near the worst days.

Why It Matters for Investors

Emotional Preparation

Knowing that bear markets are normal (they occur every 3-5 years on average) and temporary (averaging 13 months) helps you avoid panic selling. The greatest threat to long-term returns is not bear markets themselves but investor behavior during them.

Investment Strategy Implications

During bull markets:

• Continue regular investing (DCA) rather than trying to time the top
• Rebalance by selling overweight equities and buying underweight bonds
• Resist FOMO-driven concentrated bets on the "hottest" sectors

During bear markets:

• Continue or increase regular investments (you are buying at lower prices)
• Harvest tax losses on positions held outside IKE/IKZE
• Avoid checking your portfolio daily — it serves no purpose and increases anxiety

Opportunity Recognition

Bear markets create the best long-term buying opportunities. The WIG20 bought at the 2009 low more than doubled within 2 years. But this requires having cash available and psychological fortitude — both of which require advance planning.

Polish-Specific Considerations

The GPW (Warsaw Stock Exchange) is classified as an emerging market by FTSE and a developed market by MSCI. This hybrid status means Polish bear markets can be more severe than developed market bears (higher beta to global risk sentiment) but also more rewarding on the upside.

Risks and Pitfalls

1. Declaring a bear market too early — A 15% drop feels like a bear market in real-time but may be just a correction. Acting on premature bear market declarations (selling everything) often means selling near the bottom.

2. Recency bias — After a long bull market, investors forget that bear markets exist. After a bear market, investors become too conservative and miss the recovery. Both reactions are harmful.

3. "This time is different" — Every bear market feels unique and potentially permanent. COVID in 2020 felt like the end of the economy. The 2022 inflation shock felt like a regime change. Both were followed by strong recoveries. Bear markets always end — though the timing is unpredictable.

4. Sector rotation confusion — Individual sectors can be in bear territory while the broad market is bullish. Polish bank stocks dropped 40% in 2015-2016 (CHF loan crisis) while the S&P 500 was near all-time highs.

5. Leveraged positions in bear markets — A bear market that drops 30% can wipe out a leveraged investor entirely. Margin calls force selling at the worst possible time.

6. Cash drag in permanent waiting — Some investors sit in cash "waiting for the bear market" for years, missing bull market gains that far exceed what they would save by buying lower.

FAQ

How do I know if we are in a bull or bear market? You only know for certain in retrospect. The 20% threshold is arbitrary. Focus on your investment plan and time horizon rather than labeling market conditions.

Should I sell everything when a bear market starts? Almost certainly not. By the time a bear market is officially declared (20% decline), selling locks in losses and you must decide when to re-enter — a decision most investors get wrong. Historically, staying invested has outperformed market timing in the vast majority of cases.

Are bear markets good or bad? For someone accumulating wealth (working and investing regularly), bear markets are good — you buy more shares at lower prices. For someone in retirement withdrawing from their portfolio, bear markets are dangerous due to sequence-of-returns risk. Your life stage determines whether a bear market is friend or foe.

What is a "bear trap"? A temporary price decline that looks like the start of a bear market but quickly reverses. Investors who sell get "trapped" outside the market as prices recover. Similarly, a "bull trap" is a temporary rally within a bear market that sucks investors back in before prices resume falling.
