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.

information overview Some investors track currency movements alongside equities. Exchange rate fluctuations can influence international investments. 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.

Expert Insights
information overview Access to global market information improves situational awareness. Traders can anticipate the effects of macroeconomic events. 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.
