ACES' depth is important because it presents investors with an avenue to capitalize on 2022’s surprisingly robust renewable energy spending, which is occurring against the backdrop of interest tightening and high inflation in the U.S. While domestic equities account for almost 79% of ACES’ roster, many of these companies aren’t exclusively focused on the U.S. That positions the ETF to capitalize on accelerating clean energy spending in international markets. That could be a sign that the long-term thesis for ETFs such as the ALPS Clean Energy ETF (ACES) remains intact.
