What Is IWV? iShares Russell 3000 ETF
Last updated September 2026
Short answer
IWV is iShares Russell 3000 ETF, an ETF that tracks the Russell 3000 Index at a 0.20% expense ratio. IWV holds the Russell 3000, which is the Russell 1000 large-cap index and the Russell 2000 small-cap index stacked together, covering close to the whole investable US market. The breadth is genuine, but the weighting is not democratic. The ten largest positions account for around 32 percent of assets, while the two thousand smallest companies contribute a single-digit share of total weight. At 0.20 percent the fund charges several times what the cheapest total-market ETFs charge, and with $19.5 billion in assets and a 2000 launch it is the older, pricier way to own the same thing.
IWV is issued by iShares and tracks the Russell 3000 Index. It charges a 0.20% expense ratio, holds approximately $19.5B in assets under management, yields about 0.87%, and launched in 2000.
What the bottom 2,000 companies actually contribute
The Russell 3000 is built by ranking US companies by market value and taking the top three thousand. The first thousand form the Russell 1000. The remaining two thousand form the Russell 2000. Because the index weights by market capitalisation, that second group occupies a single-digit share of the fund despite being two thirds of the names in it. Someone who owns IWV does own those companies. Their combined ability to move the fund is small.
That distinction matters for anyone choosing IWV over a large-cap fund on the assumption that the small-cap sleeve is doing real work. It diversifies the list of businesses, not the sources of return. If small-cap exposure is the actual objective, a dedicated small-cap fund supplies it at a weight capable of changing a portfolio's behaviour. IWV supplies completeness instead, which is a different and more modest thing to buy.
Where the concentration sits
NVIDIA opens the fund at 6.4 percent, followed by Apple at 5.8 percent and Microsoft at 3.8 percent. Alphabet appears twice, as Class A at 2.9 percent and Class C at 2.3 percent, so the holdings table understates it: one company is 5.2 percent of the fund, not two positions of under 3 percent each. Reading the list without combining those lines gives a misleading picture of how concentrated the top actually is.
The semiconductor weight is the other thing the label hides. NVIDIA at 6.4 percent, Broadcom at 2.4 percent and Micron at 1.8 percent put more than a tenth of a total-market fund into three chip companies, before counting the chip exposure buried inside the technology sector's 36 percent. A fund named after three thousand companies moves with the semiconductor cycle more closely than most buyers expect.
The fee is the deciding variable
Total-market index funds are close to interchangeable in what they hold. Once two funds own essentially every US listed company in market-cap order, the remaining difference is the index provider's cutoff rules and the fee. Vanguard, Schwab and iShares itself all publish total-market or broad-market funds priced at a fraction of IWV's 0.20 percent, and the fee difference compounds against the holder every year the position is held.
There are still reasons the fund persists at $19.5 billion. It is the default US total-market option on some retirement plan menus. It is old enough that long-term holders sit on embedded capital gains that would cost more to realise than the fee saves. And the trading liquidity is deep. Those are situational reasons to keep an existing position, not structural advantages over a cheaper equivalent. The distribution yield is 0.87 percent.

FAQ
How is IWV different from an S&P 500 fund?
+
IWV holds roughly three thousand US companies against the S&P 500's five hundred, adding mid-caps and small-caps that an S&P fund excludes. Because both weight by market value, the overlap in actual exposure is very high: the same handful of mega-caps dominates each. The extra 2,500 names broaden what you own without changing much about how the fund behaves day to day.
Does IWV give meaningful small-cap exposure?
+
Not in the sense most people mean. The Russell 2000 portion is two thirds of the holdings but a single-digit percentage of the weight, so small-cap performance barely registers in the fund's overall result. Investors who want small-caps to influence returns generally hold a separate small-cap fund at a deliberate weight rather than relying on what a total-market fund includes by default.
Why does Alphabet appear twice in the holdings list?
+
Alphabet has two listed share classes, GOOGL and GOOG, and market-cap indices include both. The fund shows them as separate lines at 2.9 percent and 2.3 percent, but they are claims on the same company. Combined, Alphabet is 5.2 percent of IWV, which puts it above Microsoft. The same split affects several other US companies with dual share classes.
Is 0.20 percent expensive for a total-market fund?
+
It is high for the category. Broad US equity index funds are one of the most competitively priced products in asset management, and several charge a small fraction of what IWV charges for a portfolio that holds substantially the same companies in substantially the same proportions. Whether that gap matters depends on how long the position is held and whether switching would trigger a taxable gain.
What does IWV hold that a cheaper total-market fund does not?
+
Very little of consequence. Rival total-market funds track different index providers, which changes the exact cutoff for inclusion, the reconstitution schedule and the handling of recent listings. Those are mechanical differences. None of them create a systematically different portfolio. The practical distinctions between broad US equity index funds are cost, tax lot history and where the fund is available to buy.
How much technology exposure does IWV carry?
+
Technology is 36 percent of the fund, the largest sector by a wide margin. Financials follow at 12 percent, then consumer discretionary, industrials and healthcare at 10 percent each. That technology weight is not a choice the fund makes. It is what happens when you weight the US market by size and the largest US companies are technology businesses.
Is the 0.87 percent yield useful for income?
+
It is low, and that is expected for a market-cap-weighted US equity fund. The largest US companies retain earnings or return cash through buybacks rather than dividends, which pushes the aggregate yield down. Investors seeking portfolio income generally look at dividend-focused equity funds or bond funds instead. IWV's payout is a byproduct of owning the market, not a designed feature.
When is IWV the wrong tool?
+
When cost is the primary consideration and no tax constraint prevents switching, since the same exposure is available for less. It is also wrong for anyone wanting a small-cap or value tilt, because market-cap weighting delivers neither. And it duplicates rather than complements an existing S&P 500 position: holding both mostly concentrates you further into the same mega-caps.
What is IWV's expense ratio?
+
IWV has an expense ratio of 0.20% per year as of August 2026, charged by iShares and deducted from the fund's value rather than billed to you separately. On a $10,000 position that is roughly $20 a year. Fees compound over time, so on a long-term holding the expense ratio is one of the few return drivers you control. It is worth comparing against other funds that track the Russell 3000 Index before you choose.
How do I compare IWV to similar ETFs?
+
Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. IWV's figures are above; the full method is in Walnut's guide on how to compare ETFs.
