艾利科技（ALGN）股价周二重挫3.26%，收报192.81美元，成为当日惨淡股市中的领跌标的。标普500指数同期下探0.40%至6243.76点，道琼斯工业平均指数则大跌0.98%收于44023.29点。
这已是该股连续第三个交易日走低，当前股价较去年7月18日创下的263.24美元历史高位缩水26.76%。相较于同业表现，艾利科技明显落后——捷迈邦美（ZBH）逆势微升0.18%至94.03美元，登士柏西诺德（XRAY）虽小幅回落0.50%，仍以15.92美元报收。
值得注意的是，当日100万股的成交量显著超越其50日平均交易量87.7万股，显示市场交投活跃度骤增。当前股价持续承压的态势，与放量下跌的技术形态形成叠加效应，为后续走势蒙上阴影。
