Missing the 10 Best Days: The Hidden Cost of Fleeing a Volatile Market

Missing the 10 Best Days: The Hidden Cost of Fleeing a Volatile Market

May 05, 2025

When markets get rough, the instinct to “get out before it gets worse” can feel almost irresistible. Volatility breeds fear, and fear often leads to hasty decisions. But one of the most costly mistakes investors can make during a downturn is trying to time the market, especially if it means missing out on its best-performing days.

Volatility: A Double-Edged Sword

Market volatility can be unnerving. Whether triggered by economic uncertainty, interest rate changes, geopolitical tensions, or global crises, sharp price swings create an atmosphere of panic and unpredictability. But here’s the catch: the market’s best days often come right on the heels of its worst.

The Price of Missing Out

History has shown that trying to sidestep losses by exiting the market during turbulent times often leads investors to miss the recovery, which can come suddenly and powerfully. Missing even a handful of the best days can drastically reduce long-term returns.

Let’s look at some numbers. If you invested $10,000 in the S&P 500 index in 2003 and stayed fully invested for the next 20 years, you could have earned an average annual return of over 9%, growing your investment significantly.

But what if you missed the 10 best days during those 20 years?

Your returns could be cut in half.

Miss the 20 best days? Your portfolio could have grown by only a fraction of what it might have otherwise.

Why Do the Best Days Follow the Worst?

Markets are forward-looking. When pessimism is priced in, even a small positive shift, like a better-than-expected economic report or a hint of a central bank pause, can trigger sharp rallies. These snapback days are hard to predict and often happen when investor sentiment is at its lowest.

The irony? Many investors are on the sidelines during these moments, having sold out during the downturn.

Staying Invested vs. Timing the Market

Trying to time the market means you must get two decisions right:

  1. When to get out
  2. When to get back in

That’s incredibly difficult, even for professionals. Most retail investors who try to time the markets end up buying high and selling low.

Instead, staying invested, even when it feels uncomfortable, ensures you don’t miss the eventual rebound. Market history favors patience, not perfection.

What Can You Do Instead?

  • Stick to Your Plan: Investment plans are designed to weather market cycles. Let them.
  • Diversify: Spread your investments across asset classes to reduce overall risk.
  • Automate Investments: Dollar-cost averaging helps you stay consistent, buying more shares when prices are low.
  • Rebalance Periodically: Use volatility as a chance to adjust your portfolio back to target allocations, without emotional decision-making.

The Bottom Line

Volatile markets test your discipline, but reacting emotionally can lead to costly missteps. Missingthe 10 best days is a reminder that market timing can turn short-term fear into long-term regret.

By staying the course, you give your investments the best chance to benefit from both the storms and the sunshine that follow.
