Expert Insights

Passive broad-market ETFs like VOO remain the gold standard for core portfolio allocation for most long-term investors, per Todd Rosenbluth, Head of ETF Strategy at CFRA Research. “VOO’s 0.03% expense ratio creates a material compounding advantage over extended time horizons: an investor putting $100,000 into VOO would pay just $30 in annual fees, compared to $300 for a comparable broad-market ETF with a 0.30% expense ratio, adding nearly $25,000 in incremental returns over 20 years assuming 10% annualized growth,” Rosenbluth noted in a May 2 research note. Strategists at BlackRock’s Investment Institute also push back on investor concerns that the S&P 500’s recent all-time high makes VOO a less attractive entry point. Data spanning 1950 to 2025 shows that investors who missed the top 10 trading days of the S&P 500 each decade would have seen 40% lower cumulative returns than those who held through all market cycles, with timing the market consistently leading to worse outcomes for investors with 10+ year holding periods. For investors looking to balance core broad market exposure with durable rising income, VIG fills a critical portfolio niche, per JPMorgan Asset Management’s 2026 U.S. Dividend Outlook. The firm’s analysis found that companies with 10+ consecutive years of dividend growth have 30% lower volatility than the broader S&P 500, and outperform high-yield dividend stocks by an average of 2.1% annually during market downturns, as their consistent payout growth signals durable balance sheets and predictable free cash flow generation. While VOO’s elevated tech sector concentration has been cited as a minor risk by some analysts, the sector’s current 23% average free cash flow margin is twice the average for non-tech S&P 500 sectors, justifying its outsized index weighting, per Vanguard’s 2026 mid-year market outlook. Investors can further mitigate concentration risk by pairing VOO with complementary funds like VIG, which carries a 26% tech weighting, or other sector-specific or international equity ETFs to build a fully diversified long-term portfolio.
