Forget VOO: This iShares S&P 500 ETF Pays Distributions on the Same Day at Half the Bid Ask Spread

IVV and Vanguard’s S&P 500 ETF are commonly used core holdings in American retirement accounts. Both funds track the same 500 S&P 500 companies, charge the same headline fee, and have produced almost identical results across meaningful time windows. IVV can be favored for mechanical reasons, including tighter bid-ask spreads driven by heavier institutional volume and a payment schedule that reaches brokerage accounts a day or two faster. For frequent rebalancing, these frictions can translate into modest annual savings. IVV holds all S&P 500 constituents in market-cap proportions and passes through dividends, with no options overlay or factor tilt. Mega-cap tech concentration is significant, with large weights in NVIDIA, Apple, Microsoft, Amazon, Alphabet, and Broadcom.

"IVV is the simplest job in indexing: own all 500 S&P 500 constituents in proportion to their market cap and pass through the dividends. There are no options overlay, no factor tilt, and no active overlay. The expense ratio is 0.03%, putting it tied with VOO at the bottom of the cost ladder. Assets under management sit near $800 billion, which is what produces the deep liquidity and tight quoting that matter on rebalance day."

"Historical performance remains the ultimate objective test, and this head-to-head comparison produces a dead heat. Specifically, IVV has climbed 27% over the past year and 92% across a five-year horizon. VOO similarly surged 27% over the"
