Duff & Phelps Investment Management Co holds a diversified book of 148 reported positions worth $9.6B as of Q1 2026 (disclosed Apr 28, 2026, a ~28-day 13F lag). This quarter they opened Emera Inc and trimmed Equinix Inc. Their largest long position is Welltower Inc at 5% of the reported non-option book. Cloning the disclosed picks since 2013 would be +204% (+9.0%/yr). That is a simulation of the disclosed long book, not audited returns.
Following at the filing date actually beat the quarter-end book by 6.5 points over this window.
Growth of $10,000 cloning Duff & Phelps Investment Management Co's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~28 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.
