ACCE AI Infrastructure vs ACCE Clean Energy

Head-to-head: performance, risk profile, and constituent overlap between two ACCE indices.

Companies building the AI compute, data, and software layer that powers artificial intelligence. This index captures firms across the AI infrastructure stack: semiconductor companies designing GPUs and AI accelerators like NVIDIA and AMD, cloud infrastructure providers scaling AI workloads, networking specialists building high-bandwidth interconnects for data centers, and AI-native software platforms enabling machine learning operations. From chips to cloud to the applications reshaping every industry, these companies form the foundation layer that makes AI possible. The index focuses on US-listed companies deriving over 30% of revenue or strategic growth from AI infrastructure, excluding pure consumer AI applications and generic enterprise software with basic AI features.

ACCE Clean Energy →

Energy transition infrastructure: solar, wind, storage, and grid modernization. Policy tailwinds meet declining unit economics.

ACCE Verdict

ACCE AI Infrastructure has crushed Clean Energy since inception, delivering 11.39% returns versus Clean Energy's -9.91% loss—a devastating 21.3 percentage point gap that highlights the stark difference between AI's momentum and clean energy's policy-dependent struggles.

The risk profiles tell two different stories: AI Infrastructure runs at 26.6% volatility with a healthy 1.30 Sharpe ratio, while Clean Energy's brutal 39.9% volatility paired with a -0.75 Sharpe ratio shows investors getting punished for higher risk. Clean Energy's slightly deeper -19.2% drawdown versus AI's -16.5% adds insult to injury.

These indices share virtually nothing beyond their thematic focus on transformative infrastructure, with AI Infrastructure targeting the compute and software stack powering artificial intelligence while Clean Energy bets on solar, wind, and grid modernization.

**Verdict:** AI Infrastructure suits growth investors willing to ride semiconductor cycles and cloud infrastructure expansion at 1.57 beta. Clean Energy appeals to contrarian value hunters betting on policy tailwinds eventually overcoming current headwinds, but the negative Sharpe ratio demands strong conviction in the energy transition thesis. AI Infrastructure wins on every metric that matters right now.
