Our read on IDU
BA first-wave sector ETF, live since 2000: about 40 US utilities drawn from a capped Russell 1000 index. The trade-off is a legacy 0.38% fee in a corner of the market where rivals charge pennies.
The fund seeks to track an index composed of U.S. equities in the utilities sector.
Why people hold it
- Trading since June 2000, so the record spans multiple rate cycles rather than one recent stretch of market weather.
- Does the one job an index fund has: it has tracked its utilities benchmark closely, and it sits in the upper half of the broad utilities group overall.
- About 40 names pulled from the Russell 1000, with index capping rules that keep any single utility from dominating the basket.ishares.com
- Pays on a quarterly schedule and runs a billion-dollar-plus asset base: mainstream plumbing, not a thin niche listing.
Worth knowing
- The fee is the story: 0.38% versus 0.08% at XLU and FUTY and 0.09% at VPU. Same sector exposure, very different price tag.
- One sector, roughly 40 stocks. Utilities answer to interest rates and regulators, and there is nothing else here to cushion that.
- Moderately traded rather than one of the category's volume leaders, which can mean wider spreads than the biggest utilities funds.
