Adelphi Trust Co holds a diversified book of 114 reported positions worth $150.7M as of Q2 2026 (disclosed Jul 1, 2026, a ~1-day 13F lag). This quarter they opened JPMorgan Ultra-Short Income and trimmed Alphabet Inc-CL C. Their largest long position is Vanguard Mid-Cap ETF at 7% of the reported non-option book. Cloning the disclosed picks since 2026 would be +8% (+13.1%/yr). That is a simulation of the disclosed long book, not audited returns.
Adelphi Trust Co files as a bank or broker: much of this book is custody and client positions, not a proprietary portfolio.
Growth of $10,000 cloning Adelphi Trust Co's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~1 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.
Top-heavy: diversified book
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.
