Masimo Corp 已在 2026 年下市；內部人最後一份 Form 4 在 2026/6/12 申報；2026 年第 1 季末有 451 家機構在 13F 申報持有，市值合計 $96.9 億；大師中只有索羅斯基金管理持有。
2026 年第 1 季 13F 持有人
Masimo Corp 在 2026/3/31 季末的機構持股。管理 1 億美元以上美股的機構，每季結束後 45 天內要用 13F 申報多頭部位。13F 是什麼
MASI 已不再掛牌，所以這裡顯示 2026 年第 1 季；之後各季在 13F 申報持有的機構少得多。
- 持有機構
- 451
- 較 2025 年第 4 季 +65 家
- 持有股數
- 5,462 萬
- 較 2025 年第 4 季 +400.0 萬 (+7.9%)

另有 6 家機構在 2025 年第 4 季持有、還沒有申報 2026 年第 1 季 13F：沒申報不算清倉，也不計入上面的變化。
