Bear Markets Bite 35%-But History Says Staying Put Still Wins

Behavioral mistakes, not market mystery, do most of the damage

The bigger risk in a down market is not another dip. It is trying to time one when nerves are already frayed. DALBAR's investor-behavior research shows that investors often underperform market indexes not because markets are unknowable, but because pressure leads them to jump in and out, with outcomes shaped by buying, selling, switching, and timing decisions. This behavior gap is not new. In 2024, the performance gap widened to 848 basis points. In 2025, it narrowed to 72 basis points even as equity investors still withdrew 6.91% of assets, including a record monthly withdrawal rate of 2.30% in July 2025. In plain English, emotions drive trades, and trades can drag down realized returns.

A balanced portfolio can still test patience

That matters even more when investors are already dealing with a rough mixed-asset backdrop. Earlier this year, the 60/40 portfolio only recovered to its previous high in June 2025 after one of the worst bond markets in recent history. That does not mean diversification failed when it counted; it does mean a "balanced" portfolio can still feel uncomfortable for a long time. Selling in that kind of environment increases the risk that a temporary setback becomes a permanent one.

History does not promise a quick rebound. The post-2021 bear market took 18 months to recover; the 2020 crash bounced back in four months. What the record does show is that the market has recovered from these episodes and moved on to new highs. That is why staying invested can matter so much: selling to avoid pain also risks missing the sessions that do most of the recovery.

Bear markets are painful, but they have usually been the short chapter

The definition is simple, and the upside recovery is steeper

By definition, a bear market appears when prices fall at least 20% from the most recent high. That is enough to shake confidence, sharpen the headlines, and make staying invested feel foolish. But emotions do not change the long-run tape. In S&P 500 history, there have been 27 bear markets since 1928 and 28 bull markets. Stocks lose an average of 35% in bear markets and gain an average of 112% in bull markets. Bear markets also tend to be shorter, averaging 289 days, while bull markets average 988 days. The message is simple: the painful parts can be sharp, but they have usually not been the long part.

That is why waiting for "clarity" can be costly. In the last 20 years, about 42% of the S&P 500's strongest days came during a bear market, and another 36% appeared in the first two months of a bull market. In practice, some of the biggest upside days arrive before investors feel safe getting back in.

The long run still compounds through volatility

The long-run record still makes the case for patience. The S&P 500's long-run return is roughly 10% in nominal terms, or about 6.5% to 7% after inflation. That is not a promise of a smooth ride. It is evidence that equities have kept compounding through recessions, inflation spikes, bubbles, and crashes.

The long-term example is striking. A $100 investment in 1957 grew to over $98,000 by May 2026, even with all of the ugly stretches investors had to endure. In real terms, that is still about $8,400 in 2026 purchasing power.

So the mechanism is straightforward: bear markets create fear, fear can lead to bad timing, and bad timing can do much of the lasting damage. For investors today, the opportunity is to stay in the market and keep compounding rather than paying a timing tax out of self-defense.

Simplicity still has the better odds

A simpler approach can work well precisely because market cycles keep resetting. A bear market begins when prices fall at least 20% from the most recent high; a bull market begins when they rise 20% from the low. You do not need to predict which phase is coming in order to stay constructively invested. If you stay in, you avoid the classic mistake of turning a normal reset into a permanent loss by selling at the wrong time.

Fewer trades usually beat more drama

The case for simplicity is behavioral as much as it is mathematical. Retail investors have the worst trading record. That is a useful clue that many investors do not need a more elaborate strategy; they need fewer trades. A plain, diversified portfolio that sticks around gives investors a better chance of benefiting from the same long-run compounding that turned a $100 investment in 1957 into over $98,000 by May 2026.

Lower future returns would make discipline more important

Skeptics are not wrong to worry about lower future returns. McKinsey argues the next two decades could see lower US and European equity and bond returns after an unusually strong recent period. If asset-class returns are lower, complex trading becomes even less attractive, because the margin for error shrinks and fees, mistiming, and taxes matter more. In that setting, discipline matters more, not less.

What investors really need to avoid is not missing every dip. It is selling near the bottom and turning volatility into a lasting mistake.
