Should iShares Russell 1000 ETF (IWB) Be on Your Investing Radar?
Read MoreHide Full Article
Launched on May 15, 2000, the iShares Russell 1000 ETF (IWB - Free Report) is a passively managed exchange traded fund designed to provide a broad exposure to the Large Cap Blend segment of the US equity market.
The fund is sponsored by Blackrock. It has amassed assets over $46.79 billion, making it one of the largest ETFs attempting to match the Large Cap Blend segment of the US equity market.
Why Large Cap Blend
Large cap companies typically have a market capitalization above $10 billion. They tend to be stable companies with predictable cash flows and are usually less volatile than mid and small cap companies.
Blend ETFs are aptly named, since they tend to hold a mix of growth and value stocks, as well as show characteristics of both kinds of equities.
Costs
Cost is an important factor in selecting the right ETF, and cheaper funds can significantly outperform their more expensive counterparts if all other fundamentals are the same.
Annual operating expenses for this ETF are 0.15%, making it one of the cheaper products in the space.
It has a 12-month trailing dividend yield of 0.98%.
Sector Exposure and Top Holdings
Even though ETFs offer diversified exposure which minimizes single stock risk, it is still important to look into a fund's holdings before investing. Luckily, most ETFs are very transparent products that disclose their holdings on a daily basis.
This ETF has heaviest allocation to the Information Technology sector -- about 32.5% of the portfolio. Financials and Consumer Discretionary round out the top three.
Looking at individual holdings, Nvidia Corp (NVDA) accounts for about 6.94% of total assets, followed by Apple Inc (AAPL) and Microsoft Corp (MSFT).
The top 10 holdings account for about 35.64% of total assets under management.
Performance and Risk
IWB seeks to match the performance of the Russell 1000 Index before fees and expenses. The Russell 1000 Index measures the performance of the large-capitalization sector of the U.S. equity market. The Index is a float-adjusted capitalization-weighted index of equity securities issued by the approximately 1,000 largest issuers in the Russell 3000 Index.
The ETF has gained about 2.01% so far this year and it's up approximately 15.56% in the last one year (as of 01/29/2026). In the past 52-week period, it has traded between $272.36 and $381.28.
The ETF has a beta of 1.00 and standard deviation of 14.85% for the trailing three-year period, making it a medium risk choice in the space. With about 1016 holdings, it effectively diversifies company-specific risk.
Alternatives
iShares Russell 1000 ETF holds a Zacks ETF Rank of 2 (Buy), which is based on expected asset class return, expense ratio, and momentum, among other factors. Because of this, IWB is a great option for investors seeking exposure to the Style Box - Large Cap Blend segment of the market. There are other additional ETFs in the space that investors could consider as well.
The iShares Core S&P 500 ETF (IVV) and the Vanguard S&P 500 ETF (VOO) track a similar index. While iShares Core S&P 500 ETF has $765.72 billion in assets, Vanguard S&P 500 ETF has $855.49 billion. IVV has an expense ratio of 0.03% and VOO charges 0.03%.
Bottom-Line
While an excellent vehicle for long term investors, passively managed ETFs are a popular choice among institutional and retail investors due to their low costs, transparency, flexibility, and tax efficiency.
