Five Green Stocks That Outpaced Clean‑Energy ETFs, the S&P 500 and AI Funds in 2026

If you’ve been scrolling through market tickers all year, you might have noticed a handful of green‑energy names that just kept soaring. Bloom Energy (BE) topped the list, climbing more than 223 % so far in 2026. Its rival, FuelCell Energy (FCEL), wasn’t far behind, delivering triple‑digit returns that many tech‑heavy funds still envy.

Not to be outdone, mid‑cap players Vicor Corp. (VICR) and Enlight Renewable Energy (ENLT) logged solid jumps of roughly 97 % and 58 % respectively. Vicor, the AI‑powered power‑delivery specialist, has been busy turning electricity into sleek, efficient modules for high‑performance gear. Enlight, meanwhile, kept building solar, wind and storage projects across several markets, and the market rewarded that ambition.

On the smaller end of the spectrum, Aspen Aerogels (ASPN) surprised many observers with an 81 % gain. The company’s high‑performance aerogel materials, used in electric‑vehicle battery thermal barriers and ultra‑efficient insulation, have found a sweet spot as manufacturers chase lighter, cooler solutions.

What’s striking is how these five stocks have left the big clean‑energy ETFs trailing in their wake. The iShares Global Clean Energy ETF (ICLN) and the First Trust NASDAQ Clean Edge Green Energy Index Fund (QCLN) each managed barely 8 % growth, a stark contrast to the triple‑digit fireworks of the individual green stocks.

Even the broader U.S. benchmarks—S&P 500, Dow Jones Industrial Average and Nasdaq‑100—couldn’t keep up. And when you stack them against AI‑centric funds like the iShares Semiconductor ETF (SOXX), VanEck Semiconductor ETF (SMH) or the Global X Artificial Intelligence & Technology ETF (AIQ), the green names still hold their own, with BE, FCEL, VICR and ASPN beating all three.

Retail sentiment, as captured on Stocktwits, paints a mixed picture. While investors remain cautious on BE and FCEL, labeling them ‘bearish’ despite the price surge, enthusiasm is high for VICR (rated ‘extremely bullish’) and ENLT (‘bullish’). ASPN sits in a neutral zone, reflecting its smaller‑cap status.

All told, 2026 has been a breakout year for these green champions. Whether you’re a long‑term believer in clean tech or a trader hunting short‑term alpha, the performance gap between these stocks and traditional energy or AI funds is hard to ignore.
