What Stands Out About IJR
Portfolio Shape
The disclosed top holdings suggest a broad portfolio rather than a narrow single-theme sleeve. SOLS, IDCC, and MOG-A are the largest visible positions, but the top three holdings add up to only 1.99% and the top ten to 5.59%. Sector labels are limited in the visible top holdings, so the concentration read is driven mainly by the largest names themselves.
What Kind Of Overlap To Expect
IJR should show moderate to meaningful overlap with ETFs built for similar core equity exposure, but more separation from narrow sector or international funds. The biggest shared drivers usually come from the same large holdings that dominate the top of the portfolio.
When Investors Compare It
On this site, investors often compare IJR with VOO, VTI, and QQQ. Those matchups usually answer a simple question: does adding this fund create a different sleeve, or does it mostly duplicate exposure you already own? IJR currently connects to 61 live comparison pages.
