Your phone buzzes with a news alert: 'Stocks Plunge!' Is that a crash? A correction? Just a bad Tuesday? These words get thrown around loosely, but they actually mean different things — and knowing the difference can keep you from making a panicked decision with your money.
What Counts as a Correction?
A correction is a drop of 10% to 20% from a recent high. It's normal, common, and happens roughly once a year on average in the stock market.
Think of it like your favorite sneakers going on sale after being overpriced — the market sometimes gets ahead of itself, and a correction brings prices back toward a more reasonable level. Corrections usually last a few weeks to a few months, and most investors barely notice them if they're not checking their accounts daily.
The key move during a correction: do nothing dramatic. If you're investing for the long run, a 10-15% dip is just noise in the bigger picture.
What Counts as a Crash?
A crash is a sudden, sharp drop — often 20% or more in a very short period, sometimes just days. Crashes are dramatic and often tied to a specific shock: a financial crisis, a pandemic, or a bubble bursting.
Famous examples include the 1929 crash that kicked off the Great Depression, the 2008 financial crisis, and the brief but brutal COVID crash in March 2020 when markets fell about 34% in just over a month.
Crashes trigger a bear market (a longer stretch of falling prices), but not always — the 2020 crash recovered fast. Crashes feel terrifying because they're fast and the news coverage is nonstop, which makes them psychologically harder to sit through than slow corrections.
Why Do Crashes and Corrections Happen?
Markets are driven by human emotion as much as math. When prices get pushed up by excitement, eventually reality catches up — earnings disappoint, interest rates rise, or an unexpected crisis hits, and fear spreads fast.
Fear is contagious: when some investors sell, others see the price drop and panic-sell too, which pushes prices down even further. This is sometimes called a "panic sell-off." It's rarely rational, which is exactly why staying calm gives long-term investors an edge.
What Should You Actually Do?
If you're investing money you won't need for years (which should be true for almost all teen investors), the best move during a crash or correction is usually... nothing. Or better: keep contributing if you can.
Selling during a crash locks in your losses permanently. Staying invested gives your money a chance to recover when the market eventually turns around, which it has after every single crash in U.S. history so far — though nobody can promise that pattern continues forever.
This is also exactly why diversification matters: spreading your money across many companies and sectors softens the blow of any single crash.
Try It: Stress-Test Your Mindset
Before you invest real money, use our simulator to fast-forward through a simulated crash. Watch how it feels when your pretend balance drops 20% in a week.
If that makes you want to sell everything, that's useful information — it means you should keep more money in safer places and invest less aggressively. Knowing your own panic threshold before a real crash happens is one of the smartest things a young investor can do.
