Investing at all-time highs doesn’t seem like a logical strategy when investors’ instincts say, “Buy low, sell high.”
But, the S&P 500 hit new all-time highs 28 times this year (through 9/30/25), following the historical pattern of new highs clustering together.
📊 Chart 1: All-time highs that set a “market floor” since 1950 were followed by further growth in the S&P 500.
📊 Chart 2: Going back to 1988, we see comparable, or even higher, average S&P 500 total returns when investing at a new high compared to investing on any day.
So, what does this mean?
If investing for the long term, history indicates entering the market near all-time highs can still present opportunities. However, we always stress the importance of a disciplined investment approach focused on fundamentals.
