iShares S&P 100 ETF (NYSEARCA:OEF) follows the S&P 100, concentrating on a defined universe of large US companies. Its coverage is narrower than the S&P 500 and broader total-market indexes. This places more emphasis on understanding the weights of major constituents, even though the fund includes businesses from multiple industries.

Investment approach and market coverage

iShares S&P 100 ETF (NYSEARCA:OEF) uses an index-tracking mandate. The stated benchmark is S&P 100 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 10.46%; Apple at 10.13%; Microsoft at 8.09%; Amazon.Com Inc at 5.15%; Alphabet Class A at 3.44%. 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 44.05%, Communication at approximately 11.08%, Financials at approximately 10.99%. 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 S&P 100 ETF (NYSEARCA:OEF) has a listed gross annual expense ratio of 0.20% and net annual expense ratio of 0.20%. At the net rate, USD 10,000 held at a constant value for a full year would imply approximately USD 20.00 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 372.19 per share as at 3 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 S&P 100 ETF (NYSEARCA:OEF) 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.
