If you’ve been in the stock market for a while, congratulations. Now that the market has reached a new peak, you’ve probably made some money.

And if the news of a new market peak is enticing you to dip a toe back into the stock market — or perhaps drawing you in for the first time — this is a good moment to reflect on whether you have the emotional and financial resources to get in and stick with it for the long run.

The S&P 500 on Friday surpassed the peak it reached on Jan. 3, 2022. After a miserable performance in 2022, the stock market had a fabulous run. Bond prices rose, too. These increases lifted investment portfolios around the world. Celebrate, by all means.

But then get past it. If you are a long-term investor, this particular market peak isn’t likely to matter.
