Proassurance Corp 已在 2026 年下市；內部人最後一份 Form 4 在 2026/6/26 申報；2026 年第 1 季末有 222 家機構在 13F 申報持有，市值合計 $12.7 億；沒有大師持有。
2026 年第 1 季 13F 持有人
Proassurance 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
PRA 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
- 222
- 較 2025 年第 4 季 +11 家
- 持有股數
- 5,162 萬
- 較 2025 年第 4 季 +692.3 萬 (+15.5%)
- 總市值

- 另有 62 家減碼
另有 4 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。
