Cabot-Wellington Portfolio Concentration: Dominated by VTI and IEFA as of June 30, 2026

As of June 30, 2026, Cabot-Wellington, Llc maintains a significant position in the financial markets. The firm's portfolio consists entirely of publicly traded securities held directly by the entity.

The holdings are dominated by four Vanguard exchange-traded funds (ETFs), with VTI leading the allocation at 75.21%. This fund, known as "Vanguard S&P 500 ETF," represents a substantial portion of Cabot-Wellington's assets.

Two other Vanguard funds round out the top five holdings: ISHARES TR (IEFA), or "iShares Core MSCI EAFE ETF," holds 17.56% of the portfolio, while ISHARES INC (IEMG) accounts for 6.74%. The remaining allocations are held by VB (Vanguard Index Fds) at 0.43% and VT (Vanguard Intl Equity Index F) at a very small 0.06%.

This portfolio structure indicates an extremely high level of concentration, with the top five holdings accounting for 100% of the total assets under management by Cabot-Wellington as of this date. The firm's investments are heavily weighted towards large-cap US stocks and international developed markets.

The largest position is VTI, followed closely by IEFA which holds a substantial allocation to non-US equities. IEMG appears to be another significant holding within the Vanguard lineup. VB remains a minor component, while VT shows negligible weight despite being included in the top holdings list.
