欧洲股市周二持稳，权重股诺华一周内第三次遭遇临床试验挫折，拖累大盘表现。

　　截至伦敦收盘，斯托克欧洲600指数下跌0.1%，医疗保健板块下跌2.3%。诺华股价一度下跌11%，创有记录以来最大单日跌幅。该公司此前表示，用于治疗一种罕见的肌肉萎缩疾病的del-desiran在一项后期临床试验中未能达到目标。

　　相比之下，随着铜价创新高，基础资源股上涨。食品饮料股表现出色，能源股同样走强，此前沙特阿拉伯表示，多处能源设施因遭到袭击而暂停运营，推动原油价格上涨。

　　“市场正在采取观望态度，”晨星财富高级投资组合经理Mark Preskett表示，“显然石油股会获得买盘，但整体而言，市场情绪相当疲弱。”

　　市场目前已完全消化欧洲央行将在周四会议上加息的预期。接下来的其他潜在催化因素包括甲骨文和奥多比周四公布业绩，以及美联储下周政策会议。
