谁是最被低估的AI股?摩根大通:快手!
Hua Er Jie Jian Wen· 2025-08-13 01:55
在全球AI热潮中,哪只股票最被低估?摩根大通给出了明确答案。 据追风交易台消息,摩根大通8月12日发布的研报写道,"快手仍是最被低估的AI股"。该行将快手科技目标价从71港元大幅上调至88港元,上行空 间达22%,并重申快手为中国数字娱乐板块首选股。报告强调,快手"不光关乎(AI大模型)可灵",其核心广告业务增速加快以及人工智能对广 告的提振同样被低估。 可灵业务前景被大幅上调 摩根大通对快手旗下AI视频生成工具可灵的增长前景展现出强烈信心。该行将可灵2025年和2026年的收入预期分别从7.5亿元和12亿元人民币,大 幅上调61%至12亿元和19亿元人民币。 外卖业务采用轻资产模式 针对市场对快手进入外卖行业的担忧,摩根大通认为这是过度反应。据该行分析,快手8月初在其app本地服务界面上线"外卖"入口,但采用的是 以聚合为中心的轻资产模式。 具体而言,快手主要利用与美团等成熟企业的合作关系,而不是建立自营物流。快手的外卖服务发挥流量入口作用,将用户导向第三方平台来进 行履约和配送。摩根大通认为,这种轻资产业务模式可最大限度地减少前期投资,并可能通过收取流量入口服务佣金为快手带来额外变现机会。 这一乐观预期基 ...
