MACD金叉信号形成，这些股涨势不错！ 责任编辑：郭栩彤 近期，A股市场再创新高，科技成长板块成主推力，尤其算力产业链的CPO和PCB等亮眼表现带动了科 技板块的整体上扬。那么，本轮行情能持续多久？后续科技板块细分领域机会如何挖掘？围绕这些投资 者关注度较高的问题，长城基金基金经理储雯玉进行了具体解析。储雯玉表示，9月份之前市场不太会 存在大的系统性风险，但如果市场过热，上行力量也会受到限制，所以当前比较适合寻找结构性机会， 比如进行板块间的高低切换，或等待高位板块的回调布局机会。 具体到科技创新方向，储雯玉认为，由于部分科技热点板块已经接近或超过前期高点，市场也在酝酿高 低切换，比如近几个交易日PCB、光模块、稳定币、半导体制造等方向都有退潮迹象，而相对低位的AI 应用、半导体设计板块逐渐活跃。因此近期可重点关注计算机、传媒、半导体等板块。另外，三季度是 传统消费电子旺季，还可密切关注新产品发布可能带来的投资机会。 免责声明：本通讯所载信息来源于本公司认为可靠的渠道和研究员个人判断，但本公司不对其准确性或 完整性提供直接或隐含的声明或保证。此通讯并非对相关证券或市场的完整表述或概括，任何所表达的 意见可能会 ...
