Adestella returned 10.1% net in 2025, with long book gains of 12.7% partially offset by 2.6% short losses. International holdings led with 7.6% contribution versus 2.5% domestic. Top contributors included Nebius Group, which more than doubled on data center GPU demand and added over 3% to returns, Power Solutions International, which tripled on data center power demand before being exited, and Bel Fuse, which tripled on multiple expansion despite modest EBITDA growth. Detractors included Par Technology on restaurant software pessimism, RXO on freight market weakness and automation disruption, and LifeMD on guidance cuts. Manager maintains small-cap bias despite decade of underperformance, with median portfolio market cap of $2-5B. Current positioning emphasizes AI infrastructure through Dell as largest holding, betting on enterprise migration from cloud APIs to on-premise servers for cost efficiency. Portfolio also overweight aerospace aftermarket suppliers and select software companies with systems-of-record moats. Net exposure remains 90% with gross at 115%. Manager acknowledges factor concentration risks and maintains valuation discipline while awaiting mean reversion in small-cap performance.
