Underestimate the 'Inventory Hangover' After a Sector-Wide Boom

Established Platforms Defend Against AI With Data and Infrastructure Moats

Invest in 'Natural Monopolies' That Add Value to Both Sides of a Market

Jonathan Tepper's fund targets companies with limited competition, favoring "natural monopolies" like Booking.com over regulated utilities.

A Concentrated 15-20 Stock Portfolio Forces Conviction and Maximizes Returns

Identify Elite CEOs By Their Counter-Cyclical Share Buybacks

Jonathan Tepper views aggressive share buybacks during market downturns as a hallmark of a superior CEO. Unlike managers who buy back shares when things are good and the stock is high, great capital allocators like Booking.com's CEO seize moments of market fear to repurchase shares at a discount, creating significant long-term value.
