How Market Crashes Work — and Why They're Not the Problem

Staying invested through a crash is live below your means under pressure. The gap between what comes in and what goes out has been building, compounding, and working in your favor for months. A crash is the moment that tests whether you let it keep working — or whether you stop it yourself.

The financial news industry runs on urgency. A declining market is a good market for ratings — it gives anchors something to say and advertisers a reason to buy time. Every selloff arrives with a narrative that explains why this one is different from the last one. A pandemic. A banking failure. An interest rate error. A geopolitical rupture. The specifics change every cycle. The underlying behavior — investors making permanent decisions based on temporary information — stays remarkably consistent.

The market recovers. It always has. And the investors who get permanently hurt aren't the ones who lived through the crash. They're the ones who sold during it.

Morningstar's Paul Kaplan compiled monthly U.S. stock market returns going back to January 1886 — 140 years of data across every panic, depression, war, and recession the country has experienced.

The finding is not subtle: every single market crash in that 150-year record recovered and went on to new highs. Without exception. (Morningstar, March 2026 — morningstar.com)

$100 invested at the start of 2000 — through the dot-com crash, 2008, COVID, and the 2022 bear market — is worth more than $300 as of February 2026. $100 invested in 1870 would be worth $3,508,200 today.

That distinction — temporary versus permanent — is the only one that matters when a crash is happening. A market that has dropped 34% and will recover in four months is a completely different situation than a market that has dropped 34% and will never recover. One requires patience. The other requires action. The historical record makes clear which category every crash since 1886 has fallen into. Every single one has been the first kind.

Speed varies considerably. The COVID crash recovered in four months — the fastest in 150 years of data. The Great Depression took more than a decade. Here's the full picture across major crashes: (Morningstar/Ibbotson Associates SBBI, data through December 31, 2025)

Average recovery from any bear market (20%+ decline): 37 months.
Average large-blend index fund recovery: ~6 months.

The average bull market lasts 69 months. The average bear market lasts far shorter. Which means for every month spent in a downturn, investors who stay in collect many more months of upside on the other side. (Schwab Center for Financial Research, data through December 31, 2024 — schwab.com)

A $100,000 portfolio crashes 34% — the same magnitude as COVID-19 in 2020. The account shows $66,000.

Two investors are looking at that same number. One sells. One holds.

The investor who sells locks in a $34,000 loss permanently. That money is gone. The only way to recover is to get back into the market at the right time — and then compound from a smaller base. Most people who sell during crashes don't get back in at the bottom. They get back in after the recovery has already happened, buying high after having sold low.

The investor who holds does nothing. Four months later the account is back above $100,000. The $34,000 loss was real on paper and temporary in practice.

The crash didn't cause the permanent loss. The decision to sell during it did.

Take 2024 specifically. The S&P 500 returned 25.02%. The average equity investor took home 16.54%. That 8.48 percentage point gap wasn't the result of picking bad funds or paying excessive fees — it came from pulling money out at the wrong moments. Withdrawals happened in every quarter of 2024, with the largest outflows arriving right before the market surged.

The 20-year picture is more damning. Averaged out since 2004, the typical equity investor has earned 8.7% annually while the market returned 9.7%. On a million dollars, that single percentage point compounds to a $1,066,053 difference over two decades — not from bad funds, not from high fees, from the timing of when people got scared and made a move. (Gap verified: $1M at 8.7% for 20 yrs = $5,303,846 vs $1M at 9.7% = $6,369,899)

Market timing fails for a reason that goes beyond difficulty — it fails because the best days and the worst days cluster together. The explosive recovery sessions that drive most of a decade's total return tend to arrive in the weeks immediately following the scariest moments, before anyone has declared the crash officially over. An investor who sells to stop the bleeding frequently exits right before those sessions occur, and re-enters the market only after the recovery is well underway and widely reported.

Missing 10 days — out of 5,000 trading days over 20 years — cuts the final value by more than half. Missing 30 days out of 5,000 turns $73,662 into $13,206.

The investor who sold during the COVID crash in March 2020 and waited to get back in "when things settled down" missed most of a 4-month recovery. The ones who stayed collected all of it.

This is the issue the whole series has been building toward.

The emergency fund from Issue #2 isn't just about car repairs. It's what keeps you from being forced to sell investments when the market is down. When a $1,000 emergency hits someone with no cash buffer, they liquidate at the worst possible time — not because they made a bad investing decision, but because they had no financial runway.

The debt decision from Issue #4 works the same way. Someone carrying $20,000 in credit card debt at 19.58% APR is bleeding $3,916 per year in interest. During a market downturn, that monthly drain makes holding far harder psychologically — and sometimes forces liquidation to cover obligations.

The sequence — emergency fund, high-interest debt, then invest consistently — isn't just an optimization. It's what gives you the financial stability to do nothing during a crash. And doing nothing during a crash is the most valuable thing a long-term investor can do.

Historically, bear markets occur on average every 5 to 6 years since World War II — and roughly once a decade over the past 150 years. (Charles Schwab Center for Financial Research / Morningstar Historical Market Data)

They are not anomalies. They are not signs that the system is broken. They are the price of admission for capturing the long-term returns that make investing worth doing. You cannot have the 10% historical average without the years where it drops 34% or 50%. They are the same asset.

The question is never "will there be a crash?" There will be. The question is whether your financial foundation is solid enough that you can hold through it — and whether you understand the data well enough not to make the decision that turns a temporary loss into a permanent one.

Pull up your investment account and look at its current value. Then ask yourself honestly: if that number dropped 30% tomorrow — which has happened before and will happen again — would you sell?

If the answer is yes, the problem isn't your investment strategy. It's that you don't have enough financial runway underneath it yet. Emergency fund first. High-interest debt next. Then invest with a time horizon long enough to hold through what's coming.

If the answer is no — you already understand the most important thing about long-term investing. The rest is just staying consistent.

Issue #9 is the paycheck automation playbook — direct deposit splitting, auto-invest setup, and building a money system that executes the right decisions every month without requiring you to make them. After eight issues building the framework, Issue #9 is about removing yourself from the equation.

Reply and tell me: have you ever sold during a market crash? What happened? I read every reply.

Staying invested through a crash is live below your means under pressure. Everything built over the last eight issues — the emergency fund that keeps you from being forced to sell, the paid-off high-interest debt that stops the monthly bleeding, the index fund sitting in a low-cost account earning the market's return — all of it exists so that when the account drops 34% and the headlines say this time is different, you can do the most valuable thing available to a long-term investor.

Nothing. Just let it run.
