Income Research & Management holds a diversified book of 30 reported positions worth $184.5M as of Q2 2026 (disclosed Jul 24, 2026, a ~24-day 13F lag). This quarter they opened Alliant Energy Corp and trimmed Bofa Finance LLC. Their largest long position is Bofa Finance LLC at 6% of the reported non-option book. Cloning the disclosed picks since 2024 would be +9% (+4.8%/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 4.5 points over this window.
Growth of $10,000 cloning Income Research & Management's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~24 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.
