If you invest for long enough, you will see your portfolio fall sharply. Global stock markets have dropped by a third or more several times in recent decades — in 2000–2002, 2008–2009 and briefly in 2020 — and smaller falls of 10–20% are routine.
What matters isn’t avoiding crashes. It’s not letting them push you into decisions you’ll regret.
What usually happens
- Falls feel faster and scarier than rises. Headlines get louder at exactly the wrong moment.
- Some of the strongest days often come shortly after the worst ones. Investors who sell in panic frequently miss the rebound.
- Broad, diversified markets have historically recovered and gone on to new highs — though recovery can take years, and in single countries it has sometimes taken decades.
The mistakes that make losses permanent
- Selling after the fall. A paper loss becomes a real one, and you then face the impossible choice of when to get back in.
- Stopping your monthly investing. Crashes are when your fixed amount buys the most units.
- Investing money you’ll soon need. If you’re forced to sell in a crash to pay rent, the crash wins.
- Using leverage. Margin and CFDs can turn a temporary fall into a wiped-out account.
- Checking prices constantly. It turns normal volatility into stress.
A crash plan, written in advance
Write this down while markets are calm:
- My emergency fund covers ___ months of expenses, outside the market.
- My investing horizon is ___ years.
- If markets fall 30%, I will: keep my monthly investment going, not sell, and not check my account more than once a month.
- I will only change my plan if my life situation changes — not because of the news.

Talking to other long-term investors during a crash helps. So does remembering why you invested in the first place. Join the shoal.
The short version
Crashes are the price of long-term returns. Keep an emergency fund, invest only money you won’t need for years, keep investing through the falls, and don’t sell in a panic.
