AI Analysis · Q3 2026

PineStone Asset Management Inc.s March 2026 13F is a $14.23 billion 44-position quality-compounding portfolio. The AUM fell from $16.09B at year-end to $14.23B at Q1-end primarily because of broad market multiple compression in technology names; over 39 of 44 positions were reduced in shares as the portfolio team mechanically matched share counts to price declines. Taiwan Semiconductor was reduced 15.3% in shares ($111M value reduction). Alphabet -9.95% ($311M). Microsoft -2.2% ($357M). Moody's -1.1% ($189M). Oracle fully sold ($351M realized). HDFC Bank -54.5% ($210M). Against this, Mastercard was increased at $90M more despite price weakness -- a contrarian add. Amazon was increased 42% in shares ($69M). Two new core-size positions opened: KLA Corp (semiconductor process control) at $158 million and Sunbelt Rentals (construction equipment rental) at $96 million. Portfolio sector split: Technology 42%, Consumer Cyclical 21%, Financial Services 12%, Communication Services 11%, Healthcare 10%, Consumer Defensive 3%. The whaleScore of 80.00 reflects both the concentration structure and the fund's AUM scale.
