Which fund is the better buy?
For two funds seeking to represent the same thing — the totality of the U.S. stock market — the Vanguard Total Stock Market ETF and the iShares Core S&P Total U.S. Stock Market ETF do have notable differences.
The first difference is that the Vanguard fund, VTI, has nearly 1,000 more stocks in its portfolio than the iShares offering, ITOT, yet both have essentially identical performance, no matter what time frame you consider. That speaks more to the power of market-cap weighting, which significantly reduces the influence of the smallest companies, than to the funds themselves.
The second difference is the actual price, since VTI trades at a higher price than ITOT. But that probably only matters to those with limited investment capital who can’t buy fractional shares. Most people don’t face those constraints.
On a valuation basis, the Vanguard fund is currently slightly cheaper, with a forward P/E of 26.35 compared to ITOT’s 26.41. The latter’s higher ratio is likely a function of its holding fewer, higher-market-cap stocks that tend to trade at higher P/E multiples than the smallest ~1,000 stocks in VTI.
The Vanguard fund is better of the two because it is closer to fulfilling its intended task — to reflect the totality of the U.S. stock market. But as a practical matter, both funds have shown they deliver nearly identical performance and yields at the same cost. Your choice should probably be guided by whether you have easier access to one of the funds in a company-sponsored plan, like a 401(k).
