Werlinich Asset Management, LLC holds a focused book of 58 reported positions worth $261.7M as of Q2 2026 (disclosed Jul 9, 2026, a ~9-day 13F lag). This quarter Honeywell Aerospace Inc first appears in 13F filings, a listing rather than a purchase; they opened Jacobs Solutions Inc and trimmed Nvidia Corp. Their largest long position is Nvidia Corp at 16% of the reported non-option book. Cloning the disclosed picks since 2024 would be +42% (+19.9%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +45.2%, a 3.2-point gap that is the cost of the ~9-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Werlinich Asset Management, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~9 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: focused book
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.
