What history tells us about investing at market highs

The market has just hit another all-time high. You’re sitting on cash, wondering, “Is it too late to buy? Should I wait for a correction?”
This dilemma paralyzes countless investors. But here’s a surprising truth: Since 1950, the S&P 500 has spent roughly 7% of trading days at all-time highs—and 31% of those highs marked a new market floor. That’s why smart investors don’t obsess over market peaks. Instead, they follow strategies that help them build wealth regardless of where the market stands. Let’s break down how.
The psychology behind market highs
It’s understandable to fear buying at market peaks. Loss aversion makes potential losses feel far more painful than equivalent gains feel rewarding (source). When combined with recency bias (our tendency to overweight recent market volatility) we convince ourselves to wait for the “perfect” entry point (source).
But this perfectionism comes at a cost. For example, an investor who stayed out of the market during 2021’s frequent all-time highs would have missed a 28% total gain that year alone (source), while their idle cash likely earned less than 1% in a savings account. The opportunity cost of trying to time the S&P 500 often outweighs the risk of buying at a peak.
What history tells us
History reveals that all-time highs often signal strength, not weakness. Analysis of the S&P 500 from 1929 onward reveals that new all-time highs typically occur in clusters, sometimes lasting for months or even years, reflecting underlying momentum rather than isolated peaks. After a new high, the S&P 500 was higher one year later about 81% of the time, and higher five years later about 86% of the time.

Take March 2013, for example, when the S&P 500 first surpassed its 2007 peak. Many investors feared another crash, but the market went on to gain another 22% over the following year. Similarly, in 2017, the index hit record highs 62 times and still delivered strong returns.
More importantly, market highs do not mean all individual stocks are overvalued. Even during market peaks, careful analysis can reveal opportunities. For instance, in late 2015, when markets were reaching new highs, Chipotle’s stock had plummeted from around $14 (post-split) to around $9.60following the E. coli crisis. Despite the broader market’s strength, investors who focused on Chipotle’s strong brand, loyal customer base, and who believed food safety was a temporary issue were rewarded handsomely as the stock eventually climbed back to over $68 in 2024.
Even during market highs, individual companies can become undervalued due to temporary issues, missed earnings, or bad news.
Strategic approach: Build your watchlist
Ultimately, it all comes back to fundamentals. Instead of trying to predict market crashes, smart investors focus on preparation and maintaining a watchlist of high-quality companies. This preparation-over-prediction mindset ensures you’re ready to act when opportunities arise, whether the market is climbing or correcting.
Start by identifying companies with durable economic moats, consistent earnings growth, and manageable debt levels. Then, set target price ranges using valuation metrics such as price-to-earnings ratios, price-to-book values, or discounted cash flow models. When a stock reaches your target, regardless of where the broader market stands, you’re ready to invest with confidence.
While headlines may scream about the S&P 500 hitting another record high, savvy investors remain focused on the fundamentals. A stock trading at 15× P/E with 20% growth potential is still attractive, no matter the market backdrop. This principle applies whether you’re buying or selling. Disciplined investors base their decisions on company-specific factors, not market sentiment or short-term noise.
The index ETF advantage: When timing doesn’t matter
For investors focused on broad market exposure, dollar-cost averaging (DCA) into index exchange-traded funds (ETFs) removes the stress of market timing altogether. By investing consistently, whether at market highs, lows, or anywhere in between, DCA helps smooth out volatility over time.
If you’re investing $500 monthly into an S&P 500 index ETF, stick with it regardless of market conditions. Even if you buy through multiple all-time highs, your disciplined, long-term approach is likely to outperform someone who tries to time the market perfectly.
The fifth perspective
Investing during market highs requires discipline over emotion. Focus on company fundamentals, not market sentiment. Be prepared: build your watchlist before you need it. If you’re dollar-cost averaging into index funds, timing becomes far less relevant.
Most importantly, remember: time in the market typically beats timing the market. So when the market hits a new high, don’t freeze. Think like a smart investor, return to the fundamentals and ask yourself: Are any companies on my watchlist telling a different story?
