Large private foundations and endowments outside of higher education vary in how concentrated their investment portfolios are, with the Bill & Melinda Gates Foundation Trust and Lilly Endowment relying heavily on a select number of equities. While certain stocks, such as Eli Lilly & Co., have performed well, concentrated portfolios have idiosyncratic risks that could impact future returns.
Allocations vary: Equity investments by the five largest private foundations and endowments varied from the Ford Foundation's 2.2% to the Lilly Endowment's 90.9% — solely in Eli Lilly shares. The Ford Foundation lowered its equity to about 2% from nearly 39%, while increasing its allocation to alternatives/other.
Year-end equity allocations*
Concentration: Eli Lilly stock makes up most of the Lilly Endowment's investment portfolio despite a reduction to 102.9 million shares at the end of 2022, from 135.7 million in 2012. Nonetheless, the value increased to $37.7 billion from $6.7 billion during that period. Despite Warren Buffett's annual donation of Berkshire Hathaway stock to the Bill & Melinda Gates Foundation, its share count has decreased by 72% over the past decade. The foundation has also increased its ownership of Canadian National Railway Co., Deere & Co. and Waste Management Inc.
