伯克希亞哈撒韋(NYSE: BRKB)(NYSE: BRKA)股價在週末公布2025年度第四季及全年度財報後下跌約5%,投資者主要對公司營運盈餘的顯著年比下降感到擔憂。公司表示, this decline was primarily driven by a sharp year-over-year decrease in operating earnings, which fell 29.8% compared with the same quarter last year. The decrease was heavily impacted by a steep drop in the company's insurance underwriting operating earnings, which declined 54% year over year to USD 1.56 billion. 这一跌幅是相較於去年同期保單 underwriting 盈餘大幅上揚 302% 至 USD 3.41 billion 的基礎上。保險業務的盈餘波動對伯克希亞而言尤為顯著,因其在保費編輯策略上表現出arked willingness to reduce net premiums written when market competition intensifies. 公司高度重視保單 Float(即保單所產生的淨政策持有資金)及其投資運用,對於保費編輯與 Float 的管理皆採取高度 дисциpline 的態度。在此背景下,雖然保單 underwriting 盈餘出現下降,但其 Float 卻在年年成長,於2025年年底攀升至 USD 176 billion,較去年同期的 USD 171 billion 有所增加。因此,單独看保單盈餘的負面資訊並不足以完整呈現公司整體財務健全度。
