Diesslin Group, Inc. is a wealth-management firm allocating client money, specialised in financials (76% of the long book), running a $222.0M US long book across 53 positions.

The portfolio is extremely concentrated — the top 10 positions are almost the whole book. Turnover is modest: positions are typically held for years. Current anchor positions: BERKSHIRE HATHAWAY INC-CL B, JANUS HENDERSON AAA CLO ETF, INVESCO QQQ TRUST SERIES 1, VANGUARD MID-CAP VALUE ETF, ISHARES RUSSELL 2500 ETF.

Its holdings are mechanical (indexing / client flows), so position changes carry no stock-picking signal.
