摩根大通最新调整股票评级，将开利全球(Carrier Global)投资评级从"增持"下调至"中性"。此次评级调整由摩根大通分析师团队主导，主要基于对暖通空调行业周期性波动的重新评估。市场数据显示，开利全球股价在评级变动后呈现窄幅震荡，当日交易量较前五个交易日均值增长约18%。
行业观察人士指出，此次评级调整发生在北美住宅装修市场进入传统淡季之际。根据美国住宅建筑商协会最新报告，新屋安装需求指数已连续两季度环比放缓，可能影响暖通设备制造商业绩预期。不过亦有分析师认为，商用HVAC系统更换周期仍将支撑企业中长期发展。
开利全球作为全球楼宇系统解决方案龙头，其股价年内累计涨幅仍领先标普500指数7个百分点。评级调整后，彭博终端显示机构投资者持仓比例微降0.3%，期权市场隐含波动率上升至近三月高位。后续市场反应及行业基本面变化值得持续关注。
