Buy at an all-time high? What happened in 76 years of S&P 500 for those who bought on a high day

According to the data, buying on a day when the S&P 500 closed at an all-time high was not worse than buying on any other day: since 1950, the year following a high day yielded an average gain of 9.9% (positive in 75% of cases), nearly identical to the year following any day (a gain of 9.4%, positive in 75% of cases). The fear of "buying at the top" is understandable, because a high feels like a point from which you can only go down. In practice, highs tend to arrive in clusters: a market in an uptrend produces high after high.

The figures in this guide were measured by us using S&P 500 data from January 1950 to October 2026: index price only, without dividends (which would have added a few percent per year to both groups), without commissions and without tax. They describe what happened, not a promise of what will happen.

What happened after high days

Out of roughly 19,300 trading days since 1950, the index closed at an all-time high on 1,538 days, about 8% of the days. For each of them we examined what the index did one, three and five years later, and compared it to the same test across all trading days.

But: the path was not smooth

An average doesn't tell you what happens along the way. In the year after a high day, the maximum drawdown from that day's price had a median of 4.8%. But in 27% of cases the index fell at some point during the year by more than 10% from the purchase price, and in 10% of cases by more than 20%. Those who bought at the high of January 1973 or March 2000 waited years before seeing that price again.

And there are long periods without any highs at all: in 27 out of the 77 years examined, the index did not close at a high even once. In other words, "the market always comes back" is true over decades, but the wait can last years.

Why highs aren't as "dangerous" as they feel

• Highs arrive in uptrends: A market that is above The 200-day moving average And continues to rise, producing new highs again and again. The high is a symptom of a trend, not its end.
• There are no sellers "waiting to break even": Below a previous high there are people who bought high and are waiting to get out at breakeven. Above the high there is no one like that, so there is no resistance natural selling from above.
• Momentum: Many studies on Momentum show that what has been strong in recent months tends to keep being strong for a while longer. Stocks and indices at highs are, by definition, the strongest.

And what about a single stock at a high?

For an individual stock the logic is similar, with one caveat: a stock at an all-time high is often Breakout above a long base, and that's a setup trend traders look for in particular. Our Fear and Greed Index, for example, measures the number of stocks at a 52-week high versus stocks at a low, because many highs indicate a healthy market.

The caveat: an individual stock can also rise without a base, in one sharp move, far above its averages. There the problem isn't the high but the distance: the logical stop is far away, and the position size should be reduced accordingly.

What to do with this in practice

• Long-term investor: "Waiting for a correction" was, according to the data, a strategy without a clear advantage, and often a missed opportunity. Those worried about timing can spread the purchase over several months.
• Swing trader: A high is "open space" with no resistance above, but it doesn't exempt you from a stop. Set the stop according to the nearest support, and the position size according to the distance to it.
• In any case: Checking the overall market condition. See also our market statistics: seasonality by month, and what happened after readings of the Fear and Greed Index.
