Whether driven by panic and fear or the thrill of riding the highs and narrowly escaping the lows, it can be alluring to attempt to try to time the market. Fear sells and panic and anxiety can place an urgency on the price tag pushing investors to make moves now without thought or discipline. Today, possibly more than ever in history, investors are being inundated with propaganda to get out of – or back into – the market. From escalating trade tensions and tariffs to fear over a recession and inflation, many investors’ sentiment is marred with uncertainty.
But history – and data – warn of the potential dangers of timing the market. And the cost of acting on impulses can be far greater than investors may realize. As Mark Matson, Founder and CEO of Matson Money says, “I don’t know if history repeats itself, but it sure rhymes.”
Missing the Market’s Best Days Can Be Devastating

Take for example, the chart above. Say you invested $10,000 in the S&P 500 and stayed invested for 20 years. By the end of that period, your investment could have grown to more than $71,750. However, if you missed just the 10 best days in the market during that same time, your investment would have grown to only $32,871, less than half.
Miss 20 of those top-performing days, and you’re looking at just $19,723. And if you were out of the market for 30 of the best days? That $10,000 shrinks to about $12,947.
The lesson? Those top days can account for the lion’s share of long-term returns. And because all the knowable and predictable information is already available, only unknowable and unpredictable information is available moving forward, markets remain impossible to predict.
Why Market Timing Is an Imprudent Strategy
Attempting to time the market is more than just a gamble – it’s a strategy without foundation. No one – not professional money managers, not economists, not financial influencers, can consistently and accurately predict when to get in and out of the market.
Yet despite its largely poor track record, market timing remains alluring because it appeals to our desire for control and certainty. But when it comes to investing, discipline and adhering to a prudent and globally diversified investing strategy – not predictions – is what can potentially yield favorable long-term results.
Stay the Course: The Case for Academic Investing
Rather than trying to time the market, we are committed to helping investors build globally diversified portfolios, grounded in empirically tested academic investing principles, so that they can have confidence in their long-term investing strategy and can stay invested over a lifetime. This approach doesn’t rely on market forecasts or emotional reactions; instead, it’s rooted in discipline, patience, and commitment to a long-term strategy.
Investing based on academic principles—rather than headlines or hunches – can give investors great opportunity to participate in the full power of the market over time. This doesn’t guarantee a profit, nor does it shield against downturns. But it does give investors an opportunity to avoid the potentially costly mistakes that come from reactionary decisions.
A Final Word: Think Long-Term, Act Long-Term
The market will rise. The market will fall. And it will likely do so many times throughout your investing lifetime. But the most dangerous move you may make isn’t riding the waves—it’s jumping ship.
Remember: it’s not about timing the market. It’s about time in the market.
Stick to your plan. Trust the strategy. And let time—and prudent investing—do its work.
