Invesco's PBW ETF, tracking the WilderHill Clean Energy Index, focuses on companies advancing clean energy and pollution prevention. While PBW underperformed the S&P 500 over five years (-52% vs. +71%), it outperformed in the past year (29% vs. 19%). Its future performance is highly sensitive to US political outcomes, with potential gains if Democrats gain control of Congress in 2026 and win the 2028 presidential election, as they prioritize climate initiatives. Current polls suggest a Democratic advantage, indicating potential upside for PBW tied to political shifts favoring clean energy policies.
