Lesson 3: Investing During Market Crashes

Introduction: When The Market Tanks

Imagine waking up and seeing your portfolio down 30%. 

Would you stay the course, or panic and sell? 


Every investor faces this moment. What matters is how you respond. 


Market crashes feel rare and extreme, but they’re a normal part of long-term investing. 

Understanding them helps you avoid costly mistakes and even spot opportunities. 


In this lesson, you’ll learn: 

  • What causes crashes, and how markets historically recover
  • What strategies have worked (and what hasn’t worked)
  • How to stay steady when emotions run high

Historical Examples of Market Crashes

Market crashes may feel shocking, but they happen more often than you think - and recovery often comes sooner than expected. 


The Dot-Com Bust (2000-2002)

  • Triggered by overvalued tech stocks and hype around internet startups
  • Nasdaq nearly fell 80% from its peak
  • Recovery took years, but solid companies like Amazon survived and thrived


The Great Financial Crisis (2008-2009)

  • Rooted in risky mortgages and a collapsing banking system
  • S&P 500 dropped over 50%
  • Many who stayed invested saw full recovery between 4-5 years 


The COVID-19 Crash (2020)

  • Global panic led to a 34% drop in just over a month
  • Markets recovered incredibly fast, reaching new highs by late 2020
  • Example of how timing the market can backfire


Every crash is different, but one thing stays the same: long-term investors who held on came out ahead.

What Worked During Crashes

While panic is common, history shows that calm and disciplined strategies often perform best in downturns. 


Staying Invested

  • Investors who didn’t sell during crashes saw their portfolios rebound
  • Markets tend to recover faster than expected


Dollar-Cost Averaging

  • Continuing to invest at regular intervals buys more shares when prices are low. 
  • Smooths out the ride and reduces regret


Buying Quality on Sale

  • Blue-chip companies and index funds often bounce back strongest
  • Crashes are chances to buy great assets at discounted prices

What Didn't Work

Crashes tempt investors into reactionary moves, but history shows these often hurt more than help.


Panic Selling

  • Locking in losses guarantees you miss the rebound
  • Many who sold in March 2020 never got back in, missing the fastest recovery in history. 


Trying to Time the Market

  • Getting out “before it drops” or “back in at the bottom” sounds smart
  •  But timing both exit and reentry correctly is almost impossible


Chasing Trends Too Late

  • During crashes, some rush into “safe” or “hot” assets (gold, crypto, defensive stocks)
  • These may already be overpriced or volatile


Emotional decisions can feel right in the moment, but they usually backfire. Having a plan beats reacting in real-time. 


Behavioral Lessons: Emotions vs. Strategy

  • Crashes are at least as psychological as they are emotional. 

    Understanding your emotions is key to making smarter decisions. 


    Fear Amplifies Risk

    • When markets fall, it’s tempting to believe ‘this time is different’
    • Fear leads to rash decisions like selling at a loss or abandoning your plan


    Loss Aversion

    • Losing money feels twice as painful as gaining it feels good
    • This bias can push you to act defensively, even when it hurts your long-term goals


    Plans > Predictions

    • Investors who follow a clear, written plan are less likely to panic
    • Having predefined rules (e.g., "rebalance annually") helps you stay grounded when markets shake


    In a crash, your biggest enemy is not the market, but your own reaction to it.

    • History shows recovery is often faster and stronger than expected. 
    • Investors who stayed the course, kept investing, or rebalanced smartly, came out ahead.
