Ideas
Passive flows inflate S&P; reversal risk.
Clay reviews Daniel Gladiš's argument that passive investing has bid up S&P 500 valuations and concentrated the index in its largest constituents. Because active capital is a shrinking share of the market, a reversal from passive inflows to outflows could trigger a sharp decline in the S&P 500, with the largest stocks most vulnerable, making the index a less helpful and riskier benchmark.
Core holding; 10% intrinsic growth.
Gladiš holds Berkshire Hathaway as a core fund position and expects roughly 10% annual intrinsic value growth over the long term. Clay notes Berkshire's growing cash pile may make high compounding harder, but the book still treats it as a core high-quality holding.
Baby Berkshire, undervalued, index-neglected compounder.
Markel is a smaller Berkshire-like conglomerate with three engines: specialized insurance and reinsurance, a large investment portfolio including Tom Gayner's equity management, and Markel Ventures' private businesses. Gladiš estimates about $1.5 billion of annual profit against roughly a $20 billion market cap, sees it as undervalued, and notes its medium size and boring profile keep it under-owned by passive and retail investors.
Disciplined acquirer in fragmented convenience stores.
Alimentation Couche-Tard is an experienced, disciplined acquirer and capital allocator in a fragmented convenience-store industry. It has integrated acquisitions well, paid down debt quickly, grown via buybacks, and still has a long runway because it owns less than 5% of US convenience stores and gas stations; the stock has compounded around 21% annually since its IPO.
Capital-light homebuilder with huge buybacks.
NVR's post-bankruptcy model is capital-light: it buys finished land via options, pre-sells homes, uses prefabricated components and fixed-price subcontractors, and generates very high ROIC. It has net cash, buys back large amounts of stock at modest valuations, and trades at a low-teens P/E versus the market, yet the market still treats it as an ordinary cyclical homebuilder.
US housing shortage supports long-term demand.
Although homebuilding is cyclical, Clay highlights the book's view that the long-term US trend is positive because population growth and underbuilding require roughly 1.5 million new homes annually, more than has been built in many recent years.
Japan reforms, cheap, underowned, currency-hedged.
Japan is an under-owned developed market with roughly 4,000 listed companies, cheap valuations (P/E about 17 versus about 28 in the US), better recent earnings growth, lower indebtedness, and governance reforms pressuring companies to improve ROIC and shareholder returns. Gladiš's fund invested passively via Nikkei 225 futures to avoid yen currency risk, and Buffett's Japanese trading-company investments validate the opportunity.
Underfollowed banks offer low-risk mispricings.
Banks and financials are widely ignored, which creates mispricings. Clay cites Derek Pletki's success and Gladiš's view that with the right analytical framework, the banking sector offers depth and opportunities for good returns with relatively low risk; passive flows also largely avoid smaller banks.
Strongest global bank, high ROTCE.
JP Morgan is viewed as the strongest and most resilient global bank: number one in customer deposits, corporate and investment banking, credit cards, mortgages, auto lending, and payments. Under Jamie Dimon it has earned high returns on tangible equity, including 19% in the five years before the book, and was the only major US bank profitable and not needing government assistance through the GFC; Gladiš's fund bought it during the March 2020 plunge.
Cheap UK landlord mortgage bank.
OSB Group is a smaller UK specialist bank lending to professional landlords. Gladiš's fund bought it in summer 2024 when it traded around 4.5 times earnings, yielded 8.5%, and was at 0.7 times book with about 15% ROE; he saw it significantly undervalued because small banks, the banking sector, and the UK market are largely ignored by investors and passive flows.
