Longnook ETF LLC, Launches Longnook Uncommon Compounders ETF

October 28, 2026 4:18 AM EDT

Longnook ETF LLC, a founder-led registered investment adviser, today announced the launch of the Longnook Uncommon Compounders ETF (Ticker: LUNC) on the New York Stock Exchange (NYSE). The actively managed fund features an unconstrained global mandate, seeking long-term capital appreciation by searching for well-priced “uncommon compounders,” defined as overlooked companies demonstrating durable competitive advantages and strong returns on capital.

LUNC is led by Founder and Chief Investment Officer David Daglio, who brings more than 25 years of institutional asset management experience to the fund. During his tenure as Chief Investment Officer at Mellon (formerly The Boston Company), Daglio oversaw $500 billion in assets, personally managed more than $10 billion in long-only and hedged equity strategies, and earned recognition from Barron’s, Institutional Investor, and Forbes. The fund’s investment process evaluates companies across five dimensions: price, sustainable advantage, governance, balance sheet, and risk. This results in a concentrated portfolio of about 30 high-conviction ideas. The LUNC portfolio represents the direct evolution of the fundamental discipline he honed as an investor and business manager.

To manage this focused mandate, Longnook utilizes a proprietary AI tool engineered specifically for decision hygiene. While Daglio retains ultimate authority, the fund’s AI acts as an algorithmic skeptic, utilizing his pre-defined rules to objectively analyze information as it unfolds. This reduces the behavioral bias and thesis drift that often plagues active management.

“This fund represents a portion of the capital I manage for my family when seeking to generate absolute returns,” said Daglio. “Investor behavioral bias is an inherent Achilles heel in our industry. LUNC pairs the time-tested approach I have refined over my career with a ‘devil’s advocate in the loop’ AI engine designed to keep human emotion out of portfolio management. Now, we are making this exact strategy accessible to any individual.”

LUNC delivers a concentrated equity strategy typically reserved for family offices within the accessible and tax efficient wrapper of a modern ETF.
