Broad ETFs and DIY Portfolios Gain Traction

Recent research cited on April 4, 2026, indicates that a large majority of professional stock pickers have struggled to beat broad U.S. equity benchmarks. One study found that 79% of large-cap domestic equity funds underperformed the S&P 500 (SPX) in 2025. Another showed that 95% of actively managed large-cap core funds lagged the index over the past 10 years.

These results are presented as a key reason the exchange-traded fund (ETF) industry has expanded in recent years. With many active strategies trailing the market, low-cost index products are framed as a straightforward way for investors to match benchmark performance instead of trying to outperform it.

The articles contrast the risk of owning single stocks with the diversification of broad market ETFs. Buying an individual company is described as a "sample size of one," where outcomes can range from strong gains, such as past rallies in Nvidia, to sizable declines, such as Nike losing roughly half its value over a three-year span.

By comparison, funds like the Vanguard S&P 500 ETF (VOO) and Vanguard Total Stock Market ETF (VTI) hold many companies, so the impact of any one stock is reduced. The pieces emphasize that broad market ETFs represent an investment in the overall U.S. economy, which can still experience bull markets and corrections, but typically with less extreme swings at the portfolio level than single-stock holdings.

An additional benefit highlighted is that stock market index funds evolve as the economy changes. Technology is currently cited as the largest sector in the S&P 500 (SPX), while in earlier periods financials, energy, and even railroads were more dominant. Holding the broad market means an investor’s exposure shifts automatically with these structural changes.

The coverage notes the very low expense ratios on some Vanguard index ETFs. The Vanguard S&P 500 ETF and Vanguard Total Stock Market ETF (VTI) are both cited with expense ratios of 0.03%. These low costs are presented as a core advantage over higher-fee active funds and advisory arrangements.

The articles also stress that index investing does not rule out stock picking. Instead, they suggest that a broad market ETF can serve as a portfolio foundation, with individual stocks or other assets added around the edges if desired.

Separate but related coverage describes a simple Vanguard ETF portfolio that could serve as an alternative to hiring a financial advisor. Advisors are said to commonly charge about 1% of assets annually, and often place clients in diversified mixes that individual investors can replicate themselves with a few broad ETFs.

The proposed “advisor replacement” portfolio uses three funds. The Vanguard Total Stock Market ETF (VTI) holds roughly 75% U.S. large-cap and 25% U.S. mid- and small-cap stocks for domestic equity exposure. The Vanguard Total International Stock ETF (VXUS) provides exposure to both developed and emerging market foreign stocks, which have seen a recent performance comeback.

To balance equity risk, the Vanguard Total Bond Market ETF (BND) includes U.S. Treasuries, investment-grade corporate bonds, and mortgage-backed securities, adding income and diversification relative to stocks. An illustrative allocation cited is 60% VTI, 30% VXUS, and 10% BND, with the caveat that actual allocations depend on an investor’s circumstances and risk tolerance.

Across these discussions, the unifying theme is that focusing on broad asset classes, maintaining a long-term buy-and-hold approach, and minimizing fees are presented as practical ways for individual investors to build wealth without relying heavily on active management or high advisory costs.
