iShares Russell 1000 ETF (NYSEARCA:IWB) follows the Russell 1000 Index, covering large and mid-cap US stocks. This universe differs from both a smaller large-cap index and a total-market benchmark. The fund therefore gives a particular mix of company sizes, with its largest constituents and sector weights determining the practical concentration of the allocation.

Investment approach and market coverage

iShares Russell 1000 ETF (NYSEARCA:IWB) uses an index-tracking mandate. The stated benchmark is Russell 1000 Index. The benchmark defines the eligible Investment universe, and its membership and weights shape the portfolio. An index objective does not mean the fund and benchmark will match exactly. Expenses, transactions, cash balances and implementation decisions can create differences. The scope of the mandate matters when comparing this exposure with an existing portfolio, because funds with similar names may cover different securities or market segments.

Holdings and underlying exposure

In the official holdings file dated 3 November 2026, selected leading stock positions were Nvidia at 6.91%; Apple at 6.88%; Microsoft at 5.55%; Amazon.Com Inc at 3.49%; Alphabet Class A at 2.34%. These figures are security-level portfolio weights; separate securities from the same issuer may appear in other rows. Holdings and weights can change.

Aggregating the reported Equity rows by the issuer file’s sector labels gives Information Technology at approximately 35.10%, Financials at approximately 12.49%, Health Care at approximately 10.39%. These are calculated sums of rounded security weights, rather than a separate issuer-published allocation table. Cash, Derivatives and other asset classes are excluded from these sector sums. The composition helps explain which economic exposures accompany the stated mandate.

Fees distributions and share pricing

iShares Russell 1000 ETF (NYSEARCA:IWB) has a listed gross annual expense ratio of 0.15% and net annual expense ratio of 0.15%. At the net rate, USD 10,000 held at a constant value for a full year would imply approximately USD 15.00 in annual fund expenses. This is an illustrative fee calculation, excluding changes in value, brokerage costs and bid-ask spreads. Expenses are reflected within the product rather than quoted as a promised investment outcome.

The stated distribution frequency is quarterly. The schedule describes how often distributions are expected, while payment amounts depend on income and other applicable fund circumstances. A distribution is distinct from Capital appreciation and does not establish a fixed future payment. Shareholders also need to consider their own tax treatment, including any treatment of distributions or gains on sale.

iShares reported net asset value of USD 419.14 per share as at 4 November 2026. NAV measures the underlying net asset value allocated to a share; it is not an exchange closing-price quotation. Shares trade on NYSE Arca, where the transaction price can differ from NAV and where the bid-ask spread adds to the cost of entering or exiting a position.

Company size and concentration

Large-company shares remain exposed to Earnings revisions, changing valuations and broad economic conditions. A portfolio holding many stocks can still be influenced by a small group of large positions. Sector representation matters because companies in the same industry may react similarly to financing conditions, regulation or customer spending. Large companies can also earn substantial Revenue abroad, creating exposure to global Demand even within a US stock allocation.

Key Insights

iShares Russell 1000 ETF (NYSEARCA:IWB) is defined by its benchmark and eligible investment universe. Its holdings explain the actual exposure, while the fee schedule and distribution arrangements explain important ownership mechanics. These features need to be considered together: broad coverage, a particular style or a specified Maturity band each changes the risks a Shareholder takes. The investment objective remains a target, and the value of the shares can decline.
