Investing.com — Guy Spier, the prominent Zurich-based value investor and longtime disciple of Warren Buffett, is returning capital to investors in his $470 million Aquamarine Fund, citing both personal health challenges and a fundamental shift in the viability of active management.
The 60-year-old manager, who famously won a charity lunch with Buffett in 2007, noted that the meticulous research once used to beat the market is being rapidly commoditized by artificial intelligence.
Aquamarine Fund has delivered a lifetime return of 1,186% since 1997, outpacing the S&P 500, but it has underperformed the benchmark for eight consecutive years.
Spierโs decision to close shop reflects a broader malaise within the active management industry, which saw investors pull over $428 billion from active mutual funds last year in favor of passive vehicles.
The hedge fund manager argued that the “Buffett-and-Munger” philosophy of identifying overlooked, high-quality companies at reasonable prices has become increasingly difficult as data becomes universally accessible.
Spier once found alpha in obscure corners like Philippine dairy or British cereal makers, but he now suggests that “everybody is looking everywhere,” effectively erasing the information advantages that once fueled outsized returns.
The headwind for value-oriented pickers has been exacerbated by the relentless dominance of the “Magnificent Seven” technology stocks. Like many in the Berkshire Hathaway B (NYSE:BRKb) orbit, Spierโs historical aversion to high-valuation tech left his portfolio exposed during the recent era of growth-led double-digit gains.
He eventually softened his stance, holding Alphabet Inc. after observing Buffettโs 2016 entry into Apple. The late pivot was insufficient to offset the structural challenges facing those who rely on manual number-crunching to solve market puzzles.
Spierโs exit serves as a sobering data point on the future of professional stockpicking. While 54% of active funds managed to beat the S&P 500 through February, the looming turbulence of the Iran war and the integration of generative AI into research workflows are seen as permanent hurdles to consistent outperformance.
The veteran stockpicker maintains that while “original thinking” still holds value, the era of the traditional process-driven analyst is drawing to a close, as automated systems prove more efficient at synthesizing the vast datasets of the modern digital economy.
