On April 9th, the S&P 500 surged an impressive +9.52%, putting it in the top 10 largest single-day percentage gains in the index’s history. That kind of rally turns heads — it’s rare air, the kind usually reserved for moments investors remember for decades.
But before breaking out the champagne, it’s worth considering the broader context. Historically, the biggest up days in the market don’t tend to show up during periods of calm or stability. Instead, they tend to appear right in the middle of extreme stress.
Take a closer look at the dates surrounding the best days in S&P history: March 2020, October 2008, October 1987. These weren’t times of investor confidence and steady growth — they were some of the most volatile and emotionally charged periods in market history. In other words, outsized gains are often a counterpunch to outsized fear.
The Catch: The Best Days Come During the Worst Times
A common misconception among investors is that they can simply sit out the tough stretches and jump back in once things “feel better.” But that’s not how markets work.
The data is clear: missing just a handful of the market’s best days can do serious damage to long-term portfolio returns. The challenge? Those best days often occur right in the middle of the worst ones. If you’re not in the market during those moments — even if they feel terrifying — you’re likely to miss the rebound entirely.
Markets don’t schedule their recoveries. They don’t send out alerts. They just move. Often when it feels least comfortable to stay invested.
So, What’s the Playbook?
In times of uncertainty, the answer isn’t to time the market — it’s to trust your strategy. That means:
- Diversification: Across asset classes, sectors, and geographies. Don’t let your portfolio hinge on the success or failure of any single theme.
- Discipline: Resist the temptation to react emotionally to headlines or daily market swings.
- Patience: Investing is a long game. Staying the course through volatility is not easy, but it’s often where the most meaningful gains are made.
It’s natural to feel uneasy when markets are swinging wildly — up or down. But history tells us that these extremes are part of the process. They don’t mean the system is broken. They’re simply part of how markets recalibrate.
So yes, celebrate the big up days — they’re nice to see. But recognize them for what they are: moments that only reward those who had the discipline to endure the turbulence.
In times like these, your greatest advantage isn’t predicting the next move. It’s having a plan, sticking with it, and trusting that over time, patience and diversification tend to win.
As always, if you have any questions about your own plan or strategy, do not hesitate to reach out.
