4D Advisors Sells ~US$7.6 Million Stake in Masimo (MASI)

Hedge fund 4D Advisors has off‑loaded approximately 45,000 shares of medical‑technology firm Masimo Corporation (NASDAQ: MASI), equating to roughly US$7.57 million based on average pricing over the quarter. According to recent regulatory filings, this move represents a full exit of the fund’s reported position in Masimo for the period. The sale comes amid a flurry of institutional activity around Masimo, which recently won a substantial patent‑infringement verdict (see context below) but may now be encountering short‑term pressure from large block trades. While the legal win potentially strengthens Masimo’s intellectual‑property leverage, the notable reduction in institutional holdings could signal caution among some investors about near‑term risks. Analysts note that such selling activity can weigh on the stock, even if fundamentals remain intact. #Masimo #InstitutionalSelling #HedgeFundMoves #MedicalTechStocks #SlimScan #GrowthStocks #CANSLIM
