The iShares US Power Infrastructure ETF (FILL) closed Wednesday, October 7, 2026, at $25.67, marking a one-day gain of 3.18%. The move added to what has been a strong stretch for the fund over the past week.
Over the trailing seven days, FILL has risen 6.12%, reflecting sustained buying interest in the power infrastructure segment. The single-session and weekly gains stand out as particularly notable given the broader context of the fund's recent performance.
Despite the recent momentum, FILL's 30-day change remains slightly in the red at -0.35%, indicating the fund spent part of the past month under pressure before recovering. The divergence between the short-term gains and the flat monthly result suggests the bulk of the advance is concentrated in the most recent trading days.
No market capitalization figure was available for FILL as of the close. The fund focuses on U.S. power infrastructure holdings, a segment that has drawn attention amid ongoing discussions around domestic energy capacity and grid investment.
