What Should You Do When the Stock Market Crashes?
The stock market is falling. Every headline is about losses. Your portfolio is down 20%. Colleagues are talking about going to cash. This is the moment that defines long-term investment outcomes more than any bull market will. What you do in the next few weeks and months matters enormously — and the counterintuitive answer is often the right one.

Slow the First Reaction
The stock market is falling. Every headline is about losses. Your portfolio is down 20%. Colleagues are talking about going to cash. This is the moment that defines long-term investment outcomes more than any bull market will. What you do in the next few weeks and months matters enormously — and the counterintuitive answer is often the right one. The first goal is not to be brave or clever. It is to avoid letting a single price print make the decision for you. Fast moves create urgency, and urgency creates bad process. Slowing yourself down by even one review cycle usually improves the quality of the decision because you can separate the headline, the catalyst, and the actual thesis risk instead of treating them as the same thing.
Example: During the March COVID crash, the S&P 500 fell 34% in 33 days — the fastest bear market in history. Investors who sold at the bottom locked in maximum losses. Investors who held or added at the lows saw the index fully recover in just 5 months, and go on to return 100%+ by the end of .
What to watch for: VIX above 35–40 historically signals that fear is at or near peak. This is when the best long-term buying opportunities often appear — which is exactly why they feel the worst emotionally.
Diagnose the Real Problem
Once the emotion settles, the useful question is simple: did the business break, did the market environment change, or did the tape simply become disorderly for a while? Those are different problems and they deserve different responses. Investors usually make mistakes when they try to solve a structural problem with patience or a temporary liquidity problem with a permanent exit.

Use Rules Instead of Feelings
Good decisions under stress are usually pre-committed, not improvised. That means using written sell conditions, position-size limits, and a simple checklist for whether the thesis has changed. The market will happily supply urgency. Your process has to supply discipline. That is especially true when social pressure, financial media, and your own P&L are all telling you to do something immediately.

What the Historical Example Actually Teaches
Historical examples matter because they show how bad decisions cluster around discomfort, not around objective analysis. Investors often sell near fear peaks and buy back after the hard part is already over. Studying the timeline forces you to respect how quickly markets can reverse once the panic is fully priced. It also reminds you that not every sharp decline deserves rescue. Some really do break the thesis.

How to Use This as an Investor
The investors who build the most wealth in the long run are not the ones who avoided every crash. They're the ones who were prepared for crashes in advance — both financially and psychologically — so that when one arrived, they could act from a plan rather than from fear. Build the plan before you need it. The practical edge is not perfect timing. It is staying process-driven while other people become headline-driven. If you can classify the move, write down the reason for your decision, and wait for actual evidence instead of emotional relief, you will already be acting more like a professional than most of the market.
