VOO adds Bloom Energy and Illumina to its S&P 500 index holdings, replacing three underperforming stocks, though the fund's performance remains tethered to its 38% concentration in top-tier megacaps.
BE joins S&P 500 after product revenue surged 215% on AI power demand and raised guidance.
ILMN joins S&P 500 with revenue up 9% and raised EPS guidance, despite China and tariff headwinds.
TTD exits S&P 500 as revenue growth cratered from 19% to 3%.
TAP exits S&P 500 as a struggling brewer with low valuation and high dividend yield.
BLDR exits S&P 500 amid a housing downcycle.
NVDA is VOO's largest holding at 8%, and its performance heavily influences the ETF due to concentration.
Index rebalance adds BE and ILMN, removes TAP, TTD, BLDR, but impact on VOO returns is negligible due to small weights.
The Vanguard S&P 500 ETF (VOO) will undergo a minor index rebalance on September 21, 2026, adding Bloom Energy and Illumina while removing Molson Coors, The Trade Desk, and Builders FirstSource. Despite the roster changes, the impact on VOO's overall performance remains negligible due to the fund's heavy 38% concentration in its top ten holdings, particularly megacap tech stocks like NVIDIA.
No. Because VOO is a cap-weighted index fund, new entrants typically start with a weight of less than 0.1%, meaning their individual performance has a negligible effect on the total return of the ETF.
