iShares Global Clean Energy ETF stalls near $18 amid sector outflows and rising energy costs.

The iShares Global Clean Energy ETF (ICLN) surged 47% in 2025 but has recently stalled near $18, below its 52-week high of around $19. The clean energy sector faces pressure from $1.5 billion in outflows, rising Treasury yields increasing project costs, and higher oil prices boosting traditional energy appeal. Despite institutional selling, retail investor sentiment remains bullish due to growing AI data center demand and a key July 2026 tax incentive deadline. The fund’s April rebalancing and the construction deadline will test whether retail optimism or institutional caution prevails.
