10 Best Performing Stocks in May

In this article, we will look at the 10 Best Performing Stocks in May.

​May 2026 proved to be a good month for the American stock market, as the S&P 500 gained around 5.12% to top 7,500 points, and the NASDAQ Composite also gained roughly 7.8% to top 27,000 points. On May 26, Ed Yardeni, president of Yardeni Research, appeared on CNBC for an interview. Yardeni recently raised his S&P 500 year-end target from 7,700 to 8,250. He believes that the index will surpass the 10,000 mark by the end of the decade.

​He noted that the reason behind these targets is earnings growth, which he believes has been driving the markets higher. He added that it is not FOMO (Fear of Missing Out), but FEMO (Fabulous Earnings Momentum), which has been leading the markets. Yardeni also highlighted that there is still a tremendous amount of capital which is waiting to be invested in the American market. Moreover, he noted that most of the recent market pull-backs have proved to be attractive buying opportunities. Yardeni remains bullish on the overall market health and believes earnings momentum will drive growth in the future as well.

​With that, let’s take a look at the 10 Best Performing Stocks in May.

Performance in May 2026: 90.98%

Number of Hedge Fund Holders: 154
