A no-nonsense guide to understanding why markets go up and down — and why that’s actually okay
Let’s Start With a Simple Truth
Markets are scary sometimes. They drop. They swing wildly. Headlines scream. Your stomach drops with them. Every instinct tells you to do something — pull your money out, wait until things “calm down,” and get back in when it feels safer.
Here’s the thing though: that instinct, while totally human and completely understandable, is also one of the most financially costly moves you can make.
Let’s talk about why — using real numbers, real history, and zero financial jargon (okay, maybe a little, but we’ll keep it friendly).
The Big Picture: $10,000 and 56 Years of Chaos
Imagine you invested $10,000 in a broad U.S. stock market index fund back in 1970. Not a genius pick. Not a hot tip. Just a simple, boring, diversified investment in 500 of America’s biggest companies — what’s known as the S&P 500.
Now here’s the wild part: over the next 56 years, the world went absolutely sideways. We’re talking:
- The resignation of a U.S. president (Nixon, 1974)
- Oil crises, recessions, and runaway inflation
- The Cold War and its end
- 9/11 terrorist attacks
- The 2008 financial collapse (Lehman Brothers going bankrupt — the worst financial crisis since the Great Depression)
- A global pandemic that shut down the entire world economy in 2020
- Wars, natural disasters, political turmoil, bank collapses, and yes — even today’s tariff headlines
Every single one of those events caused panic. Every single one of them made investors want to run for the hills.
And yet.
That $10,000 investment? By March 2026, it had grown to approximately $3,372,574.
That’s not a typo. Three million, three hundred and seventy-two thousand dollars — from a single $10,000 investment — simply by staying put.
The average annual return over that entire period? 10.9% per year.
“But What About All That Scary Stuff?”
Great question. Let’s zoom in a little, because this is where it gets really interesting.
Every single year — yes, every year — the stock market experiences what’s called an “intra-year decline.” That’s a fancy way of saying: at some point during the year, the market drops. Sometimes a little. Sometimes a lot.
Here’s how it actually looks in the data:
- Since 1980, the S&P 500 has dropped an average of about -14% at some point during each calendar year
- In some years, those drops were brutal: -49% in 2008, -34% in 2020 (COVID), -34% in 2002 (dot-com bust)
- But here’s the kicker — in most of those same years, the market still ended the year positive
Think about that for a second. The market might be down 20% in the middle of the year, and by December 31st it’s back up and then some. If you panicked and sold when it was down 20%, you locked in that loss and missed the recovery.
In 2020, for example, the market dropped -34% in a matter of weeks when COVID hit. Terrifying. And yet, the calendar year ended +16%. Those who stayed invested made money that year. Those who bailed in March? They didn’t.
The Two Hardest Questions You’ll Ever Answer
Here’s the problem with trying to be clever and “get out before it gets worse”:
You now have to make two perfect decisions, not one.
- When do I get out?
- When do I get back in?
Markets don’t ring a bell at the top or the bottom. Nobody knows. Not your cousin who watches CNBC every morning. Not the talking heads on financial TV. Not the guy at the barbershop who seems very confident about everything.
And here’s what makes it even trickier: the biggest recovery days in the stock market often happen right in the middle of the worst times. Miss just a handful of those big up-days — because you were sitting on the sidelines waiting for things to “calm down” — and your long-term returns get absolutely crushed.
So by trying to avoid the scary dips, most people accidentally miss the big rebounds too. It’s a lose-lose.
Stocks vs. Everything Else: The Numbers Don’t Lie
“Okay,” you might be thinking, “but what if I just put my money in something safer? Gold? Bonds? Real estate? Cash under the mattress?”
Fair question. Let’s look at what happened to different types of investments starting right before the 2008 financial crash — arguably the scariest financial event most of us have ever lived through — and running through early 2026:
| Investment Type | Annualized Return |
| Stocks (S&P 500) | 10.3% |
| Gold | 10.4% |
| Home Prices | 3.9% |
| 10-Year Treasury Bonds | 2.8% |
| Inflation (CPI) | 2.5% |
| Cash | 1.5% |
| Oil | -1.2% |
A few things jump out here:
- Stocks and gold were neck and neck over this period — but gold is notoriously unpredictable and doesn’t pay dividends
- Bonds and home prices barely kept up with inflation
- Cash actually lost purchasing power in real terms after inflation
- Oil lost money outright
The takeaway isn’t that stocks are perfect. They’re not. They’re bumpy, they’re stressful, and they require patience. But over time, they’ve consistently outperformed nearly everything else — especially when you need that money to actually grow for retirement, education, or long-term goals.
So What Should You Actually Do?
Here’s the honest, simple answer: stay invested, stay diversified, and think long-term.
That might sound almost too simple. But simple doesn’t mean easy. Especially when markets are dropping and the news is terrible. Here’s a practical framework to keep in mind:
1. Zoom Out
When things feel scary, look at the long-term chart. Not the daily chart. Not even the yearly chart. The long-term chart. Zoomed out, every single crash in history looks like a small blip on the way to a much higher level.
2. Don’t Put All Your Eggs in One Basket
Diversification is just a fancy word for “don’t bet everything on one thing.” A mix of stocks, bonds, and other assets means that when one thing drops hard, the others help cushion the blow. It’s not glamorous, but it works.
3. Time in the Market Beats Timing the Market
This phrase gets thrown around a lot, but the data backs it up completely. Consistent, long-term investing beats the “get in and get out” approach almost every single time.
4. Don’t Let Emotions Drive Financial Decisions
Fear and greed are the two biggest enemies of a good investment strategy. When things crash, fear makes you sell. When things are booming, greed makes you go all in. Both are usually wrong moves at exactly the wrong times.
5. Talk to a Financial Professional — For Real
Not to get talked into something. But to have a plan before markets get scary. Because when they do get scary (and they will), having a plan already in place means you don’t have to make big, emotional decisions in the heat of the moment.
The Uncomfortable Truth About “Safe”
Here’s something that doesn’t get said enough: doing nothing with your money isn’t actually “safe.”
Inflation — the slow, steady rise in the cost of everything from groceries to rent — quietly erodes the value of cash that’s just sitting there. Money under the mattress, or even in a typical savings account, loses buying power every single year.
Real safety, over the long run, often means being willing to accept some short-term discomfort in exchange for long-term growth. That’s what a diversified, long-term investment approach is designed to do.
The Bottom Line
The stock market is volatile. It always has been. It always will be. Wars, pandemics, political drama, bank failures, natural disasters — none of it is going away. And every single time one of those things happens, there will be a very loud chorus of voices telling you to get out, stay out, and wait for clarity.
But the data — 56 years of it — tells a different story.
The people who stayed invested through Nixon’s resignation, through 9/11, through the 2008 financial collapse, through COVID, through all of it? They’re the ones sitting on life-changing wealth today.
The people who kept jumping in and out, trying to outsmart the chaos? Most of them missed the best recovery days and ended up with far less to show for it.
So here’s the simple message:
Make a plan. Diversify. Think long-term. Don’t panic. And when things get rocky — because they will get rocky — resist the urge to “do something” just to feel like you’re in control.
Sometimes the smartest move is the boring one: stay the course.
