The short version
iShares Core S&P U.S. Growth ETF (IUSG) is a BlackRock index fund tracking the S&P 900 Growth Index, the growth-leaning stocks of the S&P 500 and S&P MidCap 400. Its 0.04% expense ratio (annual cost) matches the cheapest similar funds, against a 0.11% peer average, and it adds some mid-size companies that S&P 500-only growth funds leave out. The catch is concentration: tech was about 47% of assets as of June 30, 2026.

How it works
IUSG is an index fund tracking the S&P 900 Growth Index from S&P Dow Jones Indices. The index takes the S&P 900, which combines the S&P 500 and S&P MidCap 400, and keeps stocks scoring strongly on three growth measures: sales growth, earnings change relative to share price, and momentum (the strength of a stock's price trend). As of March 31, 2026, it covered about 52% of the S&P 900's market value, with a large share in technology and communications.
When the index resets its weights each quarter, no company can exceed 23%, and companies weighing more than 4.8% can't total more than 50% combined. A check near each quarter-end forces an extra reweighting if one company tops 24% or those big holdings exceed 50%. Even so, as of June 30, 2026, NVIDIA was about 13% of the fund, Microsoft 7.4% and Apple 5.7%; the 10 largest positions totaled 53.5%.
BlackRock uses representative sampling: it holds stocks chosen to match the index's overall profile, not necessarily every member, and normally keeps at least 80% of net assets in index stocks. As of June 30, 2026, it held 390 stocks, tiny stock-index futures positions and 0.48% cash. It may lend out securities worth up to a third of its assets. Turnover, a gauge of trading, was 22%.
What it really costs
- IUSG charges 0.04% a year, versus an average of 0.11% for the similar funds below (1st of 9, cheapest first).
- Using the prospectus's standard example, $10,000 invested would cost about $4 in the first year and $51 over 10 years (assuming a 5% annual return).
| Cost of $10,000 (SEC example) | 1 yr | 3 yrs | 5 yrs | 10 yrs |
|---|---|---|---|---|
| IUSG | $4 | $13 | $23 | $51 |
In a retirement portfolio
It holds only the growth-leaning half of large and mid-size U.S. stocks, with about 47% in technology, so it fits better as a tilt beside a broader core.
IUSG could add low-cost exposure to fast-growing U.S. companies, at a 0.04% expense ratio. The tradeoff is sharp drops. It fell 51.8% in the 2008 financial crisis and did not regain its October 2007 peak until February 2011. It lost 32.3% in the 2020 COVID crash but recovered within about 3.4 months of its March 2020 low. In the 2022 bear market it fell 31.5% and needed 16.4 months from the low to recover. Its worst calendar year in price records going back to mid-2005 was 2008, a 38.6% loss. Anyone drawing money during slumps like these could be forced to cash out shares at low prices. Income is small: the yield over the 12 months to October 27, 2026 was 0.48%, paid quarterly. Past results don't predict future returns, and a plan should look at the whole portfolio, not one fund.
Who it may suit — and who should look elsewhere
May suit
- Cost-conscious long-term investors: the 0.04% expense ratio works out to $51 over 10 years on $10,000 in the SEC's example, assuming 5% yearly returns.
- Investors wanting large and mid-size U.S. growth stocks together, drawing on the S&P MidCap 400 as well as the S&P 500.
- Patient investors who can ride out drops like the 31.5% slide in 2022; its 10-year average return through 2025 was 16.55% a year.
Look elsewhere if
- Retirees who need income: the yield was 0.48% as of October 27, 2026, so dividends would cover very little spending.
- Investors wanting the whole market, including value stocks: technology was about 47% of the fund and NVIDIA about 13% as of June 30, 2026.
- People needing the money within a few years: it fell 51.8% in the 2008 crisis and didn't regain its peak until February 2011.

Questions investors ask
Is IUSG good for retirement?
It can fill a role in a retirement portfolio, mostly as a growth-focused slice rather than the whole stock allocation. IUSG costs just 0.04% a year, but it pays little income, with a 0.48% yield as of October 27, 2026, and it can swing sharply. It fell 51.8% in the 2008 financial crisis and 31.5% in the 2022 bear market. Retirement portfolios often pair funds like this with steadier holdings such as bonds.
What's the difference between IUSG and IVW?
The biggest difference is cost. Both are iShares growth funds with about 95% holdings overlap, but IUSG's expense ratio is 0.04% versus 0.18% for IVW (iShares S&P 500 Growth ETF). IUSG's index also draws on S&P MidCap 400 stocks, while IVW, as its name suggests, sticks to the S&P 500. Returns have been close: 12.4% for IUSG and 12.2% for IVW over the year to October 27, 2026. SPDR Portfolio S&P 500 Growth ETF (SPYG) matches IUSG's 0.04% cost.
Does IUSG pay dividends?
Yes, IUSG pays dividends quarterly, but they're small. Over the 12 months to October 27, 2026, it paid about $0.92 per share, a yield of 0.48%. That's typical of growth companies, which tend to reinvest profits in their businesses rather than pay large dividends. Most of the fund's return has come from rising share prices, so it isn't built to supply regular income.
What are IUSG's top holdings?
As of June 30, 2026, IUSG's largest holdings were NVIDIA (about 13% of the fund), Microsoft (7.4%), Apple (5.7%), Alphabet (5.6% and 4.5% in its two share classes), Broadcom (4.8%), Micron Technology (3.5%), Meta Platforms (3.3%), Amazon (3.3%) and Eli Lilly (2.5%). Those 10 positions made up 53.5% of assets, out of 390 holdings. Technology was about 47% of the fund and communication services about 14%.
How has IUSG performed over 10 years?
IUSG returned an average of 16.55% a year over the 10 years through December 31, 2025, according to its prospectus, compared with 14.22% for the S&P Total Market Index, a broad measure of U.S. stocks. Its five-year average was 14.55% a year. The gains came with sharp setbacks: the fund lost 28.86% in 2022, and its worst quarter, ended June 30, 2022, was a 20.64% decline. Based on share prices, it was up 13.4% in 2026 through October 27.
