NEAM's $66.3M SPY Stake Tops Buffett Secret Portfolio in New 13F

On May 29 2026, New England Asset Management disclosed its latest 13F, revealing a $66.3 million SPY position that accounts for 8.4 percent of its $786 million portfolio. The filing underscores continued institutional demand for low-cost S&P 500 exposure even after Warren Buffett's retirement as Berkshire CEO on December 31 2025. NEAM's 99 holdings remain heavily ETF-oriented, with SPY's 0.09 percent expense ratio and the index's unbroken streak of positive 20-year rolling returns since 1900 cited as key attractions. The disclosure coincides with Berkshire's record $397.4 billion cash pile and 18 percent rise in Q1 operating earnings, highlighting the tension between passive index allocations and concentrated large-cap bets.
