Sundheim's D1 Capital Buys Linde and Builders FirstSource Stakes
Billionaire Daniel Sundheim's D1 Capital Partners disclosed two new non-AI stock picks in its second-quarter filings. The fund bought over 340,000 shares of Linde plc, a stake worth about $177.2 million and 0.51% of the portfolio, and 1.6 million shares of Builders FirstSource, Inc., worth about $146.7 million and 0.42% of the portfolio. Linde is the largest industrial gas company in the world, selling oxygen, nitrogen, hydrogen and argon to refiners, steelmakers, chemical plants and hospitals. Builders FirstSource, a building materials company, is down about 38% so far this year, and bulls argue the housing downturn may be close to a bottom. The stock trades at about 20 times forward non-GAAP earnings, roughly in line with the sector median of 19.9 times, and at about 11 times forward EBITDA versus a sector median of 12 times.

The adjustments aim to ensure each index better represents its market capitalization range.

Black Bear Value Fund Sees Builders FirstSource Generating $500–800 Million in 2026 Free Cash Flow
Black Bear Value Fund highlighted Builders FirstSource in its second-quarter 2026 investor letter, noting the stock appreciated about 9% during the quarter but remains down roughly 13% year-to-date amid housing market weakness. The fund expects Builders FirstSource to generate approximately $500–800 million in free cash flow in 2026, representing a 5–9% free-cash-flow yield, and believes the company can sustain that level of cash generation even with housing activity near cyclical lows. Builders FirstSource has transformed its business since the Global Financial Crisis, growing higher-value-added operations to more than 40% of revenue, which has improved margins and made the business more resilient across the housing cycle.
Builders FirstSource, Fortune Brands, and Gibraltar Shares Fall on Iran Ceasefire Collapse
Shares of Builders FirstSource, Fortune Brands, and Gibraltar declined in afternoon trading after President Trump declared the Iran ceasefire over and threatened further strikes, driving oil prices higher and lifting bond yields in an inflation scare that hit housing-related stocks. Builders FirstSource fell 3.9%, Fortune Brands dropped 4.1%, and Gibraltar slid 3.8%. The companies, which supply insulation, roofing, siding, and other building products, face weaker demand signals as rising yields push mortgage rates up and cool the housing outlook, while surging crude oil raises production and freight costs that squeeze margins.
Builders FirstSource appears fairly valued after housing bill boost
Builders FirstSource stock appears roughly fairly valued following a rally spurred by new housing legislation. A discounted cash flow model estimates intrinsic value at about $92.57 per share, implying the stock is only about 3.3% undervalued relative to its current price. On an earnings basis, the company trades at a price-to-earnings ratio of approximately 33.0 times, which is below a tailored fair multiple of around 40.1 times, suggesting potential undervaluation. However, broader valuation checks show the stock passes only two of six metrics, indicating it is not obviously cheap. The recent bipartisan 21st Century ROAD to Housing Act has supported construction volumes, but ongoing margin and earnings pressures may limit further upside.
Builders FirstSource and Gibraltar Shares Surge After Congress Passes Housing Supply Bill
Builders FirstSource and Gibraltar shares skyrocketed after both chambers of Congress passed the bipartisan 21st Century ROAD to Housing Act, the most significant federal housing-supply legislation since 1990. The bill aims to boost supply by cutting red tape, streamlining environmental reviews, modernizing manufactured-housing rules, and barring institutional owners of 350-plus single-family homes from buying more existing homes. Builders FirstSource jumped 12.2% and Gibraltar gained 9.2% as the legislation is seen as a multi-year volume driver for homebuilders, lowering construction costs and friction. KB Home also reported a revenue beat with second-quarter revenue of $1.11 billion, exceeding the $1.10 billion consensus, while the 10-year Treasury yield dropped below 4.5%, improving mortgage-rate affordability. The structural shortage of existing homes continues to push buyers toward new construction, reinforcing the positive outlook for the sector.
Stocks Rally as Falling Crude Prices Knock Bond Yields Lower
The S&P 500 rose 0.72 percent as falling crude oil prices pushed bond yields lower, boosting equities. WTI crude tumbled more than 4 percent to a three-and-a-half-month low after more tankers openly crossed the Strait of Hormuz, increasing global supply, while the International Maritime Organization said it had received guarantees allowing hundreds of ships to exit the Persian Gulf. The drop in crude lowered inflation expectations, sending the 10-year Treasury yield down 8 basis points to a six-week low of 4.41 percent. Homebuilders and building suppliers surged after Congress passed the 21st Century Road to Housing Act, with KB Home up more than 16 percent and Builders Firstsource up more than 11 percent. Airlines and cruise operators also gained on lower fuel costs, while mining and energy stocks fell as gold, silver, copper, and crude prices declined.
Stocks Edge Higher Ahead of Micron Earnings as Oil Slump Lifts Sentiment
U.S. stock indexes are modestly higher as the market recovers from Tuesday's sharp selloff, with investors awaiting Micron Technology's earnings after the close to gauge AI demand. The S&P 500 is up 0.12%, the Dow Jones Industrial Average is up 0.21%, and the Nasdaq 100 is up 0.06%. Homebuilders and building suppliers are climbing after Congress passed the 21st Century Road to Housing Act, with KB Home up more than 16% and Builders Firstsource up more than 9%. Airline and cruise stocks are also gaining as WTI crude oil drops more than 3% to a 3.5-month low, reducing fuel costs. Mining stocks are retreating as gold, silver, and copper prices fall to multi-month lows. The 10-year Treasury yield is down 7.5 basis points to 4.422%, supported by the oil-driven decline in inflation expectations.

Housing stocks in focus as affordable housing bill advances to Trump’s desk
Housing stocks are drawing attention after a U.S. housing bill advanced to President Donald Trump’s desk, aiming to boost supply, ease regulations, and limit institutional ownership of single-family homes. A quant check on related names shows LGI Homes with a rating of 3.10, D.R.

House passes affordable housing bill, sending it to Trump for signature
The U.S. House passed the 21st Century ROAD to Housing Act by a 358-32 vote, sending the bipartisan affordable housing legislation to President Donald Trump for final approval. The Senate had approved the measure 85-5 on Monday, and Trump is scheduled to sign it at the Capitol on Wednesday. The bill aims to boost housing supply by waiving or speeding up environmental reviews for home construction and capping the number of single-family homes that large institutional investors can own. Homebuilders such as D.R. Horton, Lennar, PulteGroup, NVR, and Taylor Morrison Home, along with building-products supplier Builders FirstSource and manufactured housing companies Champion Homes and Cavco Industries, are seen as potential beneficiaries.
Builders FirstSource flagged for weak growth and declining returns after 22.7% drop
Builders FirstSource shares have fallen 22.7% over the past six months to $80.20, and a post-earnings analysis from StockStory urges caution. The report highlights three concerns: revenue grew at a compounded annual rate of just 6.2% over the last five years, below the firm’s benchmark for the industrials sector; earnings per share expanded only 8% annually over the same period; and return on invested capital has declined significantly, signaling fewer profitable reinvestment opportunities. At 16.1 times forward earnings, the stock is deemed reasonably valued but not a compelling buy, with the research team pointing to other names they prefer.
