Key Takeaways:
- CTEX returned 40% YTD through June 3, quadrupling the S&P 500's 11% gain
- AI data center power demand and a June tax credit deadline drove the rally
- The fund's $5.4M AUM and concentrated holdings amplify both upside and downside risk

CTEX surges 40% YTD, quadrupling the S&P 500 in a cleantech rally
A $10,000 stake in the ProShares S&P Kensho Cleantech ETF on Jan. 2 was worth about $14,000 by June 3, while the same money in the S&P 500 returned about $11,100 — a gap that reflects a structural repricing of clean energy as critical infrastructure rather than a policy bet.
"AI data centers need watts now, not in 2031, and the only watts available on a 2026 timeline come with solar panels and battery racks attached," Michael Williams, an analyst covering thematic ETFs, said in a June 7 note. "The fund's entire five-year return of 25% was compressed into the last 18 months from a depressed base."
CTEX opened the year at about $35 and closed June 3 at about $49, a 40% gain. The SPDR S&P 500 ETF Trust went from about $682 to about $754, an 11% return. The one-year window is starker: CTEX traded at about $19 on June 3, 2025, and now sits at $49.29, a 154% surge against SPY's 27%. Over five years, however, CTEX is up about 25% while SPY returned about 78%. The fund spent most of its life since its September 2021 inception trailing a balanced portfolio of bonds and cash.
Three forces are running simultaneously. The Energy Information Administration's May 2026 Short-Term Energy Outlook shows renewable supply growth accelerating across solar and wind through 2027. Goldman Sachs Asset Management noted in its 2026 outlook that over 90% of new US power generation capacity in the first five months of 2025 came from renewable sources, with renewables winning on cost and deployment speed against natural gas turbines facing long backlogs. The Department of Energy projects data centers will consume up to 12% of US electricity by 2028, up from 4.4% in 2023.
Energy storage has become the highest-velocity buildout in the US grid. The EIA's Electric Power Monthly for May 2026 lists battery storage projects coming online almost every month across Texas, California, and the Midwest, including utility-scale installations at 150 MWh and 200 MWh. Storage transforms solar into baseload-adjacent power, and the companies inside CTEX that build inverters, racking, and battery chemistry are the direct beneficiaries.
The third driver is policy timing. A June 2026 clean energy tax credit deadline created urgency among developers racing to qualify projects, pulling equipment orders into the first half of the year. That pull-forward demand shows up as a price spike in a concentrated, small-AUM thematic fund. CTEX held only $5.4 million in assets as of January 2026 coverage, meaning modest flows move the price hard in either direction. Add a turnaround story like SolarEdge Technologies beating Q4 2025 revenue on cost cuts, and an AI-cleantech crossover like T1 Energy securing a 50MW grid allocation from Norway's Statnett, and the portfolio reads like a list of stocks designed for exactly this moment.
The Concentration Trade Cuts Both Ways
CTEX is a focused bet on a handful of names tied to a specific policy window, a specific power-demand surge, and a specific storage buildout — not a diversified bet on the energy transition. The same playbook applied to the iShares Global Clean Energy ETF returned far less because ICLN's holdings are spread across more names and more geographies. Concentration produced the 40% YTD number, and concentration means a single bad print from a high-risk, unprofitable holding like Plug Power can take a meaningful bite out of the fund on any given day.
The fund cooled this week. CTEX fell about 4% on June 3 and is essentially flat over the past seven trading days, while SPY continued grinding higher. That lines up with the calendar: the clean energy tax credit deadline arrives this month. Once it passes, the marginal buyer shifts from developers racing to qualify projects to investors who believe the next leg of grid buildout, AI power demand, and storage economics is still ahead of itself in the prices.
Three indicators are worth watching. The EIA's monthly Electric Power Monthly report will show whether new battery storage and solar capacity additions hold or accelerate after the tax credit deadline expires. The Short-Term Energy Outlook's residential electricity price trajectory, which forecasts 4.9% nominal price growth in 2026 before decelerating, will signal whether sustained electricity inflation keeps utilities incentivized to deploy the cheapest available generation — currently renewable. And fund flows into CTEX itself: a $5.4 million AUM base means flows show up in the price within days, and a sudden expansion in shares outstanding would indicate the trade has been institutionalized rather than left to retail speculation.
The five-year track record argues this fund is a regime-dependent vehicle that prints heroic numbers when the regime is right and prints losses otherwise. The 2026 number on the screen is the regime working in favor. The question for investors is whether they want to own a $5.4 million concentrated fund as the policy catalyst rolls off, or whether a broader, more diversified version of the same trade does the job with less daily volatility. CTEX trades at a level that assumes most of the move is already in the price.
