“Portfolio Positioning In IT, we added Fabrinet and MACOM Technology Solutions to increase exposure to AI networking and data connectivity growth.”
Fabrinet - June 2026
“While we have found the stretched valuations in many hardware businesses to be problematic, we have taken a nuanced and conservative approach to find select investments in AI-related hardware companies at the cutting edge of shifting technology, such as Maruwa and former portfolio holding Fabrinet (sold in Q1 on valuation after a nearly six-fold appreciation since our initial investment in August 2020). We also believe we are approaching an inflection point in software stocks.”
Fabrinet - June 2026
“Alongside the memory and interconnect reductions above, we exited Ciena, Ultra Clean, KLA, Kokusai Electric, Arista Networks, Fabrinet and Vertiv, several having closed the gaps we originally underwrote, and released further capital from Tesla, Shopify, Mercadolibre and Robinhood to concentrate the Fund on the technology stack itself; the ServiceNow exit completed in April.”
