"During the quarter, we initiated new positions in Semtech, Tradeweb Markets Inc. (NASDAQ:TW) and SiTime. Tradeweb operates one of the largest global over-the-counter fixed income electronic trading marketplaces. We reinitiated a GardenSM position following a prior exit in mid-2025, with the stock now trading at a more attractive valuation and the recent pause in market share gains appearing temporary. Continued share gains in interest rate swaps, strong international growth and a long runway toward the electronification of fixed income markets support a path to sustained growth and margin expansion. We view the business as a durable compounder with limited disruption risk."
