The iShares Core S&P 500 ETF (IVV) outperformed the Vanguard 500 Index Fund ETF (VOO) by 10 basis points over the past year, driven by structural advantages in securities lending and dividend reinvestment timing. While both funds track the same S&P 500 index, IVV’s standalone ETF structure and securities lending revenue provided a slight edge, particularly for taxable accounts held at non-Vanguard brokers.

data insights Some traders rely on alerts to track key thresholds, allowing them to react promptly without monitoring every minute of the trading day. This approach balances convenience with responsiveness in fast-moving markets. Over the past year, the Vanguard 500 Index Fund ETF (VOO) returned 32.12%, while the iShares Core S&P 500 ETF (IVV) returned 32.22%, according to recently released data. Over a ten-year period, VOO returned 318.99% versus IVV’s 318.56%, indicating that the long-term performance divergence remains minimal. However, the difference in returns is attributable to fund structure rather than index composition, as both ETFs track the S&P 500. IVV operates as a standalone ETF, which allows it to generate securities lending revenue and maintain tighter bid-ask spreads. VOO, on the other hand, uses a mutual fund share class design that historically suppresses capital gains distributions, enhancing tax efficiency for long-term holders. In the fourth quarter of 2025, IVV’s dividend distribution of $2.413592 per share exceeded VOO’s $1.771 per share, partly reflecting securities lending income. Additionally, IVV’s ex-dividend dates cluster in the middle of the month, while VOO’s occur later in the quarter, potentially affecting dividend reinvestment outcomes.

Key Highlights
data insights Alerts help investors monitor critical levels without constant screen time. They provide convenience while maintaining responsiveness. - Performance divergence: IVV’s 32.22% one-year return compared to VOO’s 32.12% highlights a 10 basis point advantage, which may compound over time for larger portfolios. - Securities lending revenue: IVV’s ability to lend out shares of underlying holdings generates incremental income that can boost total returns, a factor most retail investors may not fully account for. - Tax implications: VOO’s mutual fund share class structure historically helped minimize capital gains distributions, making it potentially more tax-efficient for investors in taxable accounts, especially those who hold Vanguard mutual funds directly. - Dividend timing and reinvestment: IVV’s mid-month ex-dividend schedule could allow earlier reinvestment of dividends compared to VOO’s later-quarter timing, potentially amplifying returns over multiple periods. - Brokerage considerations: For investors using non-Vanguard brokers, IVV’s tighter spreads and securities lending advantages may make it a more attractive core S&P 500 holding, whereas VOO’s tax benefits are best realized within Vanguard’s ecosystem.

Expert Insights
data insights Monitoring commodity prices can provide insight into sector performance. For example, changes in energy costs may impact industrial companies. From a professional perspective, the performance gap between IVV and VOO underscores the importance of fund structure beyond mere expense ratios. While both ETFs are low-cost leaders, the 10 basis point difference last year may be meaningful for institutional investors or long-term accumulators. Securities lending revenue, while variable, could continue to provide a modest performance boost for IVV, particularly in rising rate environments where demand for borrowed shares increases. For taxable accounts, VOO’s tax efficiency remains a key advantage, but only if the investor holds it at Vanguard to capture the full benefits of the mutual fund share class design. At other brokers, IVV’s structural edge in dividend timing and lending may outweigh VOO’s historical tax benefits. However, past performance does not guarantee future results, and the difference in returns may narrow or reverse depending on market conditions, lending demand, and regulatory changes. Investors should evaluate their holding period, brokerage platform, and tax situation before choosing between these two near-identical S&P 500 ETFs. Neither fund can be recommended as a “better” choice without considering individual circumstances, and the 10 basis point advantage from securities lending may not persist.
