IUFS packages one slice of the S&P 500 — its financials sector — as a standalone UCITS ETF. The honest take: at 0.15% TER it's cheap for a sector fund, it accumulates dividends, and its basket is dominated by Berkshire Hathaway and the money-center banks rather than an even spread across the sector. Owning it is a deliberate bet that financials beat the broad market from here — a satellite you add on purpose, not a core.
What's inside
| Ticker | Name | Weight |
|---|---|---|
| BRK.B | Berkshire Hathaway, Inc. | 12.45% |
| JPM | JPMorgan Chase & Co. | 11.24% |
| V | Visa, Inc. | 7.20% |
| MA | Mastercard, Inc. | 5.77% |
| BAC | Bank of America Corp. | 4.58% |
IUFS doesn't spread evenly across banks, insurers, and payment networks — it's top-heavy: the top two names alone are worth almost a quarter of the fund, and the top five make up 41% of the basket. Look past the top of the table and three sub-groups emerge: money-center banks (JPMorgan, Bank of America, Wells Fargo, Citigroup), Wall Street investment banks (Goldman Sachs, Morgan Stanley), and payment networks (Visa, Mastercard, American Express) — plus Berkshire Hathaway, a conglomerate GICS classifies as financials but whose businesses (insurance, rail, utilities, and public-equity stakes) look nothing like a bank's.
Costs and structure
At 0.15% the ongoing charge matches sector sibling IUHC and is cheap for a sector-sliced fund — €75 a year on a €50k position, only a touch above a broad S&P 500 tracker like VUAA at 0.07%. Replication is full physical — iShares holds the underlying constituents directly rather than tracking them through a swap. The fund is Irish-domiciled (ISIN IE00B4JNQZ49) and accumulates dividends inside the wrapper, so there's nothing to reinvest by hand and no tax event until you sell. It launched on 20 November 2015 — the same day as IUHC — giving it a decade-long record across the rate cycles that move bank margins directly. Base currency is USD, and at about €1.79 billion it's a smaller, more niche fund than the broad trackers. The benchmark is the S&P 500 Capped 35/20 Financials Index NTR — the financials members of the S&P 500, with cap rules that stop any single name from dominating (not binding today, with BRK.B at 12.45%). The full methodology is on iShares' product page.
Performance in context
Live data temporarily unavailable for this comparison.
IUFS against VUAA — the whole S&P 500 — is the comparison that frames the decision, because financials already sit inside VUAA at market weight. Holding IUFS on top is a statement that you want more of the sector than the index gives you by default. When financials lead — a steepening yield curve, a credit expansion, strong capital-markets activity — IUFS pulls ahead of the broad index; when the market is driven by megacap tech, as it has been for much of the past decade, a financials-only fund lags the S&P 500 it's carved from. Read the chart as a test of whether the sector has actually earned its overweight, not a forecast that it will. The same tilt-versus-core question shows up with a very different sector in CNDX vs VUAA — Nasdaq's tech concentration instead of Wall Street's.
Who buys it and why
IUFS is a satellite for an investor who already owns a broad core — an S&P 500 fund like VUAA or a developed-markets fund like IWDA — and wants to deliberately overweight financials on top of it. The case is usually one of two: you hold a specific view that a steepening yield curve or a credit-cycle recovery favours banks and payment networks, or you want more exposure to Berkshire Hathaway-style compounding than the S&P 500's market-cap weight gives you. Either way it's a considered tilt, not a starter holding. If you don't hold that view, your broad fund already owns JPMorgan, Berkshire Hathaway, and Visa at market weight, and you skip both the extra line to manage and the concentration risk that comes with a two-name-heavy sector fund.
