Stocks rose for a third month in May, fueled by an explosive rally in chipmakers and artificial intelligence.
The S&P 500 briefly dipped below its April low but quickly rebounded to end the month up 0.2 percent. The Nasdaq-100 surged 8 percent, its third monthly gain above 5 percent this year. The technology-heavy index, home to AI stocks like Nvidia (NVDA) and Microsoft (MSFT), hit a new 52-week high while the S&P 500 remained below last summer’s high.
The AI frenzy came to a peak on May 24 when NVDA forecast revenue 53 percent above Wall Street’s estimates. That briefly lifted its market capitalization above $1 trillion. Alphabet (GOOGL) also introduced new AI tools on May 10.
Last month saw anxiety over the national debt ceiling and mixed economic data. Fitch Ratings placed the AAA credit rating of the U.S. on negative watch as politicians fought over the the borrowing limit. The economic reports showed inflation slowing, employment stabilizing and industrial activity improving.
Assuming the debt ceiling passes Congress, attention will likely focus on some big economic numbers. First comes the employment report on Friday. May’s inflation report is on June 13. The Federal Reserve will announce interest rates and its outlook on June 14. Those headlines could potentially shape sentiment for months into the future.
