May was basically the market’s redemption arc. After a rough start to the year, the Nasdaq and S&P 500 decided to remind everyone why they’re the cool kids, posting their best month since November 2023. We’re talking 9.6% for the Nasdaq and 6.1% for the S&P 500—not too shabby.
Here’s the thing though: the winners weren’t your typical suspects. Energy stocks, which everyone had written off as yesterday’s news, came roaring back. NRG Energy absolutely crushed it with a 42.3% jump in May. The catalyst? They scooped up LS Power’s natural gas portfolio and virtual power plant operations, basically doubling their energy generation capacity. That’s the kind of move that gets Wall Street’s attention. NRG is up 75% year-to-date and analysts think there’s still 10% more upside.
Constellation Energy wasn’t far behind, jumping 37% in May. The Baltimore-based utility got a boost from solid Q1 earnings, but the real magic came from Trump’s executive order pushing nuclear energy acceleration. Constellation is America’s nuclear energy heavyweight, so they’re basically sitting on a goldmine. The stock is up 28% YTD with analysts seeing another 3% of upside.
But here’s where it gets interesting: tech stocks also had a moment. AppLovin, an AI-powered advertising software company, soared 45.9% after selling off its mobile gaming business for $400 million while keeping a 20% stake. Smart move—they’re doubling down on their fast-growing ad tech business. The Trade Desk, which helps companies target digital ads, skyrocketed 40.3% on a massive earnings beat and new product launches. These aren’t household names, but they’re the kind of companies that actually move markets.
On the blue-chip side, Disney led the Dow with a 24.3% May surge, while NVIDIA and Microsoft also posted solid double-digit gains. Disney’s bounce-back is particularly interesting given all the streaming wars drama—sometimes the old guard still knows how to deliver.
The broader picture? Information technology led the charge with 11.3% returns, followed by industrials at 9.5% and communication services at 9.3%. Only healthcare and energy were negative for the month overall, though obviously energy’s story is more nuanced given those stellar individual performers.
What’s really happening here is that the market is finally getting comfortable with the idea that the economy might actually be okay. After months of recession fears and tariff anxiety, May felt like investors collectively exhaled. Energy stocks benefited from infrastructure plays and nuclear enthusiasm. Tech stocks rode the AI wave. And the old-school dividend payers like Disney reminded everyone that sometimes boring can be beautiful.
The takeaway? May proved that diversification still matters. Whether you were betting on nuclear power, AI advertising, or streaming entertainment, there was something for everyone. The market’s not just about the Magnificent Seven anymore—it’s finally spreading the wealth around.
