今日盘中，国泰君安国际（01788.HK）股价出现显著上涨，涨幅达5.10%，引发市场关注。截至发稿时，该股报6.2港元。
根据盘中交易数据，国泰君安国际于11:59分出现大手买入，成交量为99.7万股，成交价为6.2港元，涉资618.14万港元。这笔大额交易可能是推动股价上涨的主要因素之一。值得注意的是，截至当时，该股已上涨1.974%，日内最高价达6.24港元，最低价为5.71港元，总成交量高达4.741亿股，总成交金额达28.231亿港元，显示出较强的市场活跃度。
然而，市场上还出现了一些矛盾的信息。早盘09:32分左右曾有报道称该股出现急速下跌5.10%，报价5.770港元。这一反差可能表明国泰君安国际股价在交易日内经历了较大波动。此外，7月15日的南向资金数据显示，港股通增持该股2326.00万股，或许也对今日的股价走势产生了一定影响。投资者应密切关注该股后续走势及相关公司公告，以获取更准确的市场信息。
