半导体设备和测试公司Onto Innovation Inc.（股票代码：ONTO）今日盘后股价大跌8.52%，尽管公司公布的季度业绩超出市场预期。这一意外走势引起了投资者的广泛关注。
根据公司发布的财报，截至3月31日的季度调整后每股收益为1.51美元，高于分析师平均预期的1.47美元，也显著高于去年同期的1.18美元。公司营收同比增长16.5%，达到2.6661亿美元，略高于分析师预期的2.663亿美元。尽管业绩表现亮眼，但投资者似乎对公司的前景持谨慎态度。
造成股价下跌的原因可能有多方面。尽管公司业绩超预期，但市场可能对未来增长潜力存疑。值得注意的是，过去三个月分析师的平均盈利预期下降了约1.7%，这可能暗示市场对公司未来表现的预期有所降低。此外，公司今年迄今股价已下跌24.9%，表明投资者可能对整体半导体行业前景持谨慎态度。尽管如此，分析师仍对该公司保持乐观，给予"买入"评级，12个月目标价中位数为205.00美元。在目前市场环境下，投资者需密切关注公司未来的业绩指引和行业动态。
