ITOTAiShares Core S&P Total U.S. Stock Market ETF

IYYCiShares Dow Jones U.S. ETF

In short

ITOT The S&P family's answer to total-market indexing: large, mid and small U.S. stocks in one 0.03% wrapper, running since 2004. Same fee as the Vanguard and Schwab giants, a different index rulebook.

IYY A 2000-vintage broad US equity fund, IYY packs roughly a thousand large- and mid-cap names into one ticker and hugs its index tightly. The trade-off: it charges several times what today's cheapest total-market wrappers do.

Stated mandate

ITOT The fund seeks to track the performance of the S&P Composite 1500, representing U.S. stocks across market capitalizations.

IYY The fund seeks to track the investment results of a broad-based index composed of U.S. equities, providing broad exposure to U.S. large- and mid-cap stocks.

Why people hold it

ITOT 0.03% a year, matching the category's biggest names (VTI, SCHB) and sitting below what the typical fund in this group charges.
One index, no tilts: U.S. stocks across market caps in cap-weight order. The mandate it prints is the mandate it runs.
Trading since 2004 and now a multi-billion-dollar fund with active daily volume, so spreads are rarely the story.
Plain 1940 Act fund structure, cash paid out quarterly.

IYY Roughly a thousand large- and mid-cap US stocks in one line item, the whole domestic blue-chip and mid-tier field without picking names.ishares.com
Tracking is the strong suit here: it follows the Dow Jones U.S. Index with very little drift, among the tightest implementations in the total-market group.
Launched in 2000, one of the older broad-market ETFs still trading, with a record spanning several full market cycles.
A multi-billion-dollar iShares fund that pays out quarterly.

Worth knowing

ITOT Cap weighting puts the megacaps in the driver's seat; the long tail of smaller names is a thin slice of the basket.
SPTM tracks the same declared index at the same 0.03% fee, so the pick comes down to platform, spreads and existing tax lots.
All-equity and all-U.S. by design: no bonds, no foreign stocks in the wrapper.

IYY The 0.20% annual fee is the sticking point: VTI, ITOT and SCHB deliver comparable total-market exposure at 0.03%.
Thinly traded next to the category's giants, so spreads and limit orders matter more, especially on larger tickets.
The mandate targets large and mid caps, so the small-cap end of the US market sits outside the index.ishares.com
