What to Do When the Stock Market Drops

At some point after you start investing, the market will fall hard. Not might, will. Your account balance will shrink week after week, headlines will use words like "bloodbath" and "worst since," and a voice in your head will say get out before it goes to zero.

This article exists for that exact moment. Read it now, while things are calm, so future-you has something to hold onto.

Drops are a feature, not a glitch

Here is the rough historical rhythm, based on a century of S&P 500 data:

Drop size	How often it has happened
10%+ (correction)	About every 1-2 years
20%+ (bear market)	Every 4-6 years on average
40-50% (crash)	A few times per generation

Every single one so far has eventually been followed by a recovery to new highs. Every one. The 2008 crisis, the 2020 pandemic crash, the dot-com bust, all of them look like blips on a 30-year chart.

A crash is the market doing the thing it periodically does, and it is precisely why stocks pay better long-run returns than savings accounts. The volatility is the price of admission.

The math of panic selling

Selling during a crash converts a temporary decline into a permanent loss. That is the whole mechanism of how ordinary investors lose money in downturns. They lock it in, then wait "for things to feel safe" to buy back, and safe feelings only return after prices already recovered. Sell low, buy high, the exact opposite of the plan.

Missing the rebound is shockingly expensive too. The market's best single days cluster tightly around its worst ones, and studies keep finding that missing just the 10 best days over a couple decades slashes your total return. To catch the recovery you have to be present for it, which means staying in.

The actual playbook

So the market is down 25% and your stomach hurts. Here are the steps, in order. Keep contributing on your normal schedule, since your automatic investments are now buying shares at a discount. This is dollar-cost averaging's finest hour. Do not sell, unless your actual life circumstances changed, since a scary chart is not a circumstance. Check your account less. The portfolio does not heal faster under observation, and every look is a fresh invitation to do something dumb. If you have spare cash beyond your emergency fund, adding some is historically great, though it is optional, since staying the course is the main event.

And if you genuinely cannot sleep, that is real information, not about this crash, but about your allocation. It means your stock percentage was too aggressive for your nerves. The fix is adjusting your target mix after the recovery, calmly, not dumping everything mid-panic.

What this money is for

One caveat underneath all of this. The stay-the-course advice applies to long-term money, invested for goals 5, 10, or 30 years out. Money you need next year for tuition or a house down payment never belonged in stocks in the first place, and that is what high-yield savings is for. If a crash catches money that was mis-parked, the lesson is about parking, not about markets.

The investors who end up wealthy are not the ones who dodged every crash, since nobody reliably does that, not even professionals. They are the ones who were unremarkably, boringly present through all of them. Your only real job during a crash is to keep being one of those people.
