Strategy: Broad index
Low-cost funds that hold an entire market or index at market-cap weights and make no attempt to select securities. Return is the index return less a small fee, and dividends are a by-product of what the underlying companies choose to pay rather than an objective of the strategy. Differences between funds tracking the same index usually come down to fee, wrapper structure, share price and trading liquidity, not to holdings.

Current income is low and outside your control, so these need pairing with something else if the portfolio has to produce cash today.

What ITOT vs VOO actually do

VOO
Vanguard's S&P 500 tracker, holding the 500 large-cap US companies in the index at their market-cap weights.

It replicates the index in full and makes no attempt to pick winners, so its return is the index return less a very small fee. As an open-end fund it can lend securities and put incoming dividends back to work inside the portfolio between the quarterly payment dates. Dividends are whatever the underlying companies happen to pay, which means yield is an output of the strategy and never a target of it.

Suits almost any long-horizon US equity allocation, including as the growth engine sitting behind higher-yielding income positions. Not a fit for someone whose portfolio needs to produce meaningful current cash flow.
