Home Construction ETFs See Inflows as Warren Buffett Buys Homebuilders

iShares U.S. Home Construction ETF

ITB

+0.92%

The first ETF under my microscope is the iShares U.S. Home Construction ETF

, the dominant option for investors looking to target U.S. homebuilders. With over $2.9 billion in assets under management, ITB tracks 46 companies through the Dow Jones U.S. Select Home Construction Index.

The top holdings include D.R. Horton and Lennar, two of the largest publicly traded homebuilders in America. Other core holdings span across the value chain, including PulteGroup, Toll Brothers, and NVR. ITB also holds building material suppliers like Sherwin-Williams and Masco, and home improvement retailers like Home Depot and Lowe’s, offering exposure beyond just residential developers.

The following three-month chart shows a sharp recovery in price performance, with ITB up 16.21% as of August 18. That rally began around July 11, well before Berkshire Hathaway’s 13-F disclosure on August 14. ETF flows began turning positive in late July and ramped up significantly into August. This is after several months of outflows, suggesting a reversal in investor sentiment.

That timing matters. Buffett’s disclosure came after the surge in flows and price. This implies that institutional money may have already started positioning for a rebound in home construction, with the Berkshire news acting more like a confirmation than a catalyst.

SPDR S&P Homebuilders ETF

XHB

+0.74%

When you analyze ETF flows, it pays to understand not just the tickers, but also how each fund is constructed and what role it plays in a portfolio. A great example of this is the SPDR S&P Homebuilders ETF

. While it may sound similar to ITB on the surface, XHB tracks the S&P Homebuilders Select Industry Index, which is equal weighted.

That structural difference matters. XHB gives a greater share of its portfolio to small- and mid-cap companies, as opposed to ITB, which leans heavily into large-cap names like D.R. Horton and Lennar. This makes XHB a more volatile, high-beta play on the housing market, capturing more upside in bullish conditions but also more downside when sentiment turns.

The three-month chart reflects this dynamic. XHB rose 13.55% over the period, less than ITB, but did so with heavier and more consistent inflows. That’s a sharp contrast with ITB, which saw muted net flows overall and only turned positive on a cumulative basis in recent weeks.

This divergence may be explained by the investor base. ITB is likely used by more long-term allocators, while XHB may attract more short-term traders. That could explain why XHB flows surged ahead of Buffett’s 13-F filing, as traders anticipated momentum and piled into a more aggressive homebuilder vehicle.
