There is no single best building and construction ETF: the funds can target residential homebuilders, the broader construction industry, or infrastructure owners and suppliers. Compare each fund’s holdings and index rules first, then its current prospectus expense ratio and recent trading liquidity. The examples below are U.S.-listed funds; their figures are dated snapshots, not permanent characteristics.
Start with the exposure, not the fund name
“Building and construction” is not one consistent investment category. A homebuilder fund may focus on residential construction companies and related businesses. A broader construction fund can select companies across the building supply chain. An infrastructure fund may include utilities, railroads and other asset owners alongside construction and materials businesses.

Those differences can matter more than a small fee gap. Read the fund’s investment objective, index methodology, complete holdings and industry allocations. Check the holdings’ as-of date, since portfolios change. The official pages for ITB, XHB, PKB and IFRA describe distinct mandates.

How the four U.S.-listed examples differ
| Fund | Exposure and index approach | Reported holdings and fees | Reported liquidity snapshot |
|---|---|---|---|
| ITB — iShares U.S. Home Construction ETF | Tracks an index of U.S. companies in residential construction and related industries. | 0.37% expense ratio; $2.17 billion net assets, as reported by BlackRock on September 9, 2026. The summary prospectus is dated July 31, 2026. | 0.04% 30-day median bid-ask spread, as of September 9, 2026. |
| XHB — State Street SPDR S&P Homebuilders ETF | Seeks to correspond generally to the S&P Homebuilders Select Industry Index, which State Street describes as modified equal-weighted. Its holdings also include building products and related consumer categories. | 33 holdings and 0.35% gross expense ratio, as shown on the State Street fund page. | 0.04% 30-day median bid-ask spread, as of September 20, 2026. |
| PKB — Invesco Building & Construction ETF | Tracks the Dynamic Building & Construction Intellidex. Invesco says the fund and index are rebalanced and reconstituted quarterly in February, May, August and November. | 30 holdings, as reported in Invesco’s Q4 2025 fact sheet; 0.50% management fee and 0.57% total expense ratio on Invesco’s fund page. | Not stated in the cited Invesco materials. |
| IFRA — iShares U.S. Infrastructure ETF | A broader infrastructure fund, not a pure construction fund. Its mandate includes infrastructure asset owners and enablers, including utilities and railroads as well as materials and construction businesses. | 161 holdings and 0.30% expense ratio, as reported by BlackRock on September 9, 2026. | 0.03% 30-day median bid-ask spread, as of September 9, 2026. |

#1 Best Overall
Compare holdings and index rules
Look beyond the top company names. The number of holdings alone does not show how concentrated a fund is or whether its portfolio matches the exposure you want. Review the largest positions, their combined weight, sector allocations and the index’s selection and weighting rules.
- ITB: residential construction and related industries.
- XHB: homebuilding exposure with a modified equal-weighted index; the portfolio also reaches into building products and related consumer categories.
- PKB: construction exposure through the Dynamic Building & Construction Intellidex methodology, with quarterly reconstitution and rebalancing.
- IFRA: infrastructure asset owners and enablers, a wider remit that includes utilities and railroads.
A weighting or selection method describes how an index is built; it does not establish that the fund will outperform. Use dated holdings and allocations to check what the fund actually owns rather than inferring its exposure from its label.
Compare total fund fees, not just management fees
Use the latest prospectus to compare each ETF’s total annual operating expense ratio. If a provider lists both a management fee and a total expense ratio, keep them distinct: PKB’s cited figures are 0.50% and 0.57%, respectively. The examples above show stated expense ratios from 0.30% for IFRA to 0.57% total for PKB, but the funds do not have identical mandates.
As a simple illustration, on a $10,000 investment held for one year, a 0.30% expense ratio works out to approximately $30 in fund expenses, while a 0.57% ratio works out to approximately $57. This arithmetic is not a forecast of total ownership cost: it excludes compounding, changes in account value, transaction costs and investor-specific expenses. Brokerage commissions and bid-ask costs may also apply; Invesco notes that ordinary brokerage commissions may apply to PKB.

No single statistic captures how easily an ETF can be traded. Compare recent median bid-ask spread, average trading volume and premium or discount to net asset value (NAV), using the same date or observation window for every fund where possible. A fund’s market price can differ from its NAV.
The cited spread figures are not a same-day comparison across all four funds, and the cited Invesco materials do not state a PKB spread. They therefore do not establish a universal liquidity winner. Even a narrow reported spread does not guarantee the same cost for every order: market depth, trade size, time of day and volatility affect execution.
A limit order can set the maximum price you are willing to pay when buying or the minimum you will accept when selling. It may help control the execution price, but it does not guarantee that the order will fill. For a fair comparison, check all funds’ current trading statistics on the same basis and consider the size and timing of your own trade.

A practical comparison checklist
- Define the exposure. Decide whether you want residential homebuilders, a wider construction and building-products group, or infrastructure owners and enablers.
- Verify the mandate. Read the objective and index methodology, then inspect dated holdings, concentration and industry allocations.
- Check the latest prospectus. Compare total annual operating expense ratios and distinguish them from management fees.
- Compare trading data on one date window. Review median spread, trading volume and premium or discount to NAV rather than relying on a single metric.
- Match the fund to the decision. Do not choose solely by fee, recent performance or one liquidity statistic; these funds provide materially different exposures.
