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.
