Thursday was one of those days where it felt like everything went right. U.S. stocks climbed higher across the board, with the Dow Jones index gaining more than 300 points as investors found plenty of reasons to be optimistic.

Leading the charge was FuelCell Energy Inc. (FCEL), which posted the kind of earnings beat that makes analysts scramble to revise their models. Shares rocketed 31.4% to $10.38 after the company reported quarterly results that weren't just better than expected—they were substantially better.

The clean energy company saw revenue climb 12% year over year to $55.0 million, crushing analyst estimates of $44.752 million by more than $10 million. But the really impressive part was on the bottom line: the net loss per share narrowed dramatically to 85 cents from $2.21 in the prior-year period. On an adjusted basis, the loss per share improved to 83 cents from $1.85, handily beating the consensus estimate for a loss of $1.04.

Big Movers Across Multiple Sectors

While FuelCell grabbed headlines, it wasn't even the day's biggest gainer. That distinction went to Sable Offshore Corp (SOC), which absolutely exploded 65% to $8.73. The catalyst? The Pipeline and Hazardous Materials Safety Administration confirmed Wednesday that it agrees with Sable's conclusion that its pipeline linking the Santa Ynez Unit to the Pentland Station terminal in Kern County, California, qualifies as an interstate pipeline facility under the Pipeline Safety Act, according to an SEC filing. For a pipeline company, federal regulatory approval is about as good as news gets.

Trump Media & Technology Group Corp (DJT) surged 35.2% to $14.16 after announcing a merger agreement with TAE Technologies. The deal sent shares of the Truth Social parent company sharply higher as investors weighed the implications of the combination.

Cannabis Stocks Light Up

The cannabis sector enjoyed a strong session, with multiple names posting double-digit gains. Canopy Growth Corp (CGC) climbed 20.6% to $2.32, while Village Farms International Inc (VFF) rose 16.2% to $4.86. Tilray Brands Inc (TLRY) added 15.3% to $14.85, rounding out a solid day for marijuana stocks.

Clean Energy and Tech Rally

Plug Power Inc (PLUG) jumped 15.3% to $2.49 after announcing it installed a 5MW GenEco electrolyzer for the Cleanergy Solutions Namibia green hydrogen project. The system supports Africa's first fully integrated commercial green hydrogen facility in Walvis Bay, marking a significant international expansion milestone for the company.

But the real action in tech was happening in semiconductors. Micron Technology Inc (MU) led the sector higher with a 14.4% surge to $258.07 following strong quarterly earnings and upbeat guidance that had analysts rushing to raise their price targets. The chip maker's optimism about future demand rippled through related stocks.

Western Digital Corp (WDC) gained 8.3% to $180.01, while Lam Research Corp (LRCX) added 7.9% to $167.25. Seagate Technology Holdings PLC (STX) climbed 7.3% to $297.91, as the entire storage and semiconductor equipment sector caught a bid from Micron's positive outlook.

Other Notable Gainers

Day One Biopharmaceuticals Inc (DAWN) rose 13.2% to $9.92, continuing its recent momentum.

Ondas Holdings Inc (ONDS) jumped 10.8% to $8.17 after naming Brigadier General Patrick Huston as Chief Operating Officer. The appointment of military leadership can signal strategic shifts, particularly for companies operating in defense-adjacent sectors.

Almonty Industries Inc (ALM) gained 8.3% to $8.48, while Hut 8 Corp (HUT) rose 8.3% to $43.51. Canaccord Genuity analyst Joseph Vafi maintained a Buy rating on Hut 8 and raised his price target from $54 to $62, providing additional fuel for the cryptocurrency mining company's rally.

Lululemon Athletica Inc (LULU) jumped 6.9% to $222.27 after reports emerged that Elliott Management took a $1 billion stake in the athletic apparel company. When an activist investor with Elliott's reputation puts that kind of money to work, the market tends to take notice.

GE Vernova Inc (GEV) gained 6% to $650.68 after Jefferies upgraded the stock from Hold to Buy and raised its price target from $736 to $815. The energy equipment spinoff continues to attract positive attention from Wall Street analysts as it establishes itself as an independent entity.

All in all, it was a day where the bulls were firmly in control, with gains spanning clean energy, cannabis, semiconductors, and consumer discretionary sectors. When that many different areas of the market are working simultaneously, it's usually a sign that investor confidence is running high.
