港股上市公司云知声（09678.HK）今日盘中大跌10.49%，引发市场关注。截至发稿时，该股报价较前一交易日收盘价大幅下跌，成交活跃。
消息面上，云知声近日公布了2025年中期业绩报告，显示公司上半年亏损明显扩大。报告显示，云知声上半年收益为4.05亿元人民币，同比增长20.2%。然而，期内亏损达2.98亿元人民币，同比增加16.6%；公司拥有人应占亏损2.97亿元人民币，同比扩大16.4%；每股基本亏损4.28元人民币。这一财务表现可能是导致投资者信心受挫、股价下跌的主要原因。
值得注意的是，尽管股价下跌，云知声近期也传出了一则积极消息。该公司已获恒生指数有限公司选定，将于2025年9月8日起被纳入恒生指数系列的成分股，包括恒生综合指数、恒生综合中小型股指数、恒生互联网科技业指数等。这一消息原本可能会对股价产生积极影响，但似乎被公司亏损扩大的消息所抵消。投资者需密切关注云知声后续的业务发展和财务表现，以评估其长期投资价值。
