中字头个股表现 | SOE Blue-chip Performance
在市场整体调整背景下，"三桶油"（中石油、中石化、中海油）逆势大涨，延续了近期中字头蓝筹的强势表现。机构普遍认为，低估值、国企改革预期和经济复苏是主要驱动因素。
Against the broader market decline, the "big three" oil SOEs (PetroChina, Sinopec, CNOOC) rallied strongly, continuing the recent outperformance of SOE blue-chips. Institutions generally attribute this to low valuations, SOE reform expectations and economic recovery.
