XUU vs VUN: Choosing the Better US Total Market ETF

The main difference between XUU and VUN is that VUN uses the CRSP U.S. Total Market Index (CRSP US TMI) as its benchmark and is part of the Vanguard fund family while XUU replicates the performance of the S&P Total Market Index (S&P TMI) and is part of BlackRock’s iShares fund family.

CRSP stands for the Center for Research in Security Price and is an affiliate of the University of Chicago Booth School of Business.

The CRSP US TMI is comprised of close to 4,000 constituents across the size spectrum from mega and large-cap to small-cap and micro-cap stocks that collectively make up almost 100% of the US public equity market.

Like the CRSP US TMI, the S&P TMI has a total of 4,227 constituents that make up the US equity market from small and micro-cap stocks to large and mega-cap stocks.

However, the allocations to each sub-component of the equity market differ slightly in each of these benchmarks.
