Market crashes are terrifying. Headlines scream “WORST DAY SINCE 2008.” Your portfolio drops 20-30%. Everyone is panicking.

But here’s the truth: every market crash in history has been followed by a recovery. Every single one.

The investors who profit most from crashes aren’t the ones who sell at the bottom — they’re the ones who stay calm and buy more.

Market crash strategy — timeline, buy zones, and crash playbook

The Crash Timeline

PhaseWhat HappensWhat You Should Do
Week 1-2Panic selling, headlines everywhereDo nothing. Turn off notifications
Month 1-3Fear peaks, “this time is different”Start buying if you have cash
Month 3-6Recovery begins, investors still scaredKeep buying — best opportunity
Month 6-12New highs, missed opportunityStay invested, wait for next pullback

The Crash Playbook: DO

1. Stay Invested

The worst thing you can do is sell at the bottom. History shows:

2020 COVID Crash-34%5 months+120% by 2021
2022 Bear Market-25%2 years+40% by 2024
2018 Correction-20%4 months+50% by 2019

2. Buy More at Lower Prices

If you have cash on hand, crashes are sales events:

Market DropBuy Signal
-10% from topStart watching closely
-20% from topBegin buying (moderate)
-30% from topStrong buy opportunity
-40%+ from topOnce-in-a-decade chance

3. Rebalance Your Portfolio

If stocks dropped and bonds stayed stable:

4. Dollar-Cost Average

Instead of investing $12,000 all at once, invest $1,000/month for 12 months:

MonthPriceShares Bought
1$10010 shares
2$8511.8 shares
3$7513.3 shares
4$8012.5 shares
5$9011.1 shares
6$9510.5 shares

Result: Average cost = $87.50 vs. original $100. You bought 69.2 shares instead of 60.

The Crash Playbook: DON’T

1. Don’t Panic Sell at the Bottom

MistakeCost
Selling at -30%Lock in 30% loss
Missing 10% recoveryLose 10% gain
Missing 20% recoveryLose 20% gain
Total damage50% worse than holding

2. Don’t Try to Time the Market

Even professional fund managers can’t consistently time the market. Studies show:

3. Don’t Check Your Portfolio Daily

Daily checking leads to emotional decisions. Instead:

FrequencyBenefit
WeeklyEnough to stay informed, not enough to panic
MonthlyBetter for long-term investors
QuarterlyBest for hands-off investors

4. Don’t Change Your Strategy

Your investment plan was made during calm times. Don’t change it during a crisis. The plan accounts for crashes — that’s why you have bonds and diversification.

The Psychology of Crashes

Why We Panic

-20% drop”I’m losing everything""I’m buying at a discount”
Bad news”It’s going to zero""Companies still operate”
Friends selling”I should sell too""They’re making a mistake”
Headlines”This time is different""It never is”

How to Stay Calm

  1. Remember the math: Every crash has recovered
  2. Focus on companies: You own businesses, not ticker symbols
  3. Turn off notifications: Don’t watch CNBC during crashes
  4. Talk to a rational friend: Someone who’s been through crashes before
