美国油田设备供应商Cactus Inc.（股票代码：WHD）今日盘中股价大涨5.07%，引起市场广泛关注。
此次股价上涨主要受益于美国银行全球研究部（Bank of America Global Research）对该公司评级的上调。分析师将Cactus Inc.的投资评级从"劣于大盘"（Underperform）上调至"中性"（Neutral），同时将目标价从39美元上调至40美元。这一积极的评级变动显示出分析师对公司未来表现的信心有所提升。
分析师评级的变动通常会对股价产生显著影响，尤其是来自知名机构的评级调整。此次美国银行全球研究部的评级上调，不仅反映了对Cactus Inc.基本面的看好，也可能吸引更多投资者关注该股，从而推动股价上涨。投资者应密切关注公司未来的业绩表现，以验证此次评级调整的合理性。
