一脉阳光（02522）今日盘中大涨5.29%，引发市场关注。这一显著涨幅可能与近期利好政策及资金流向有关。
政策面上，国家药监局近日就《关于优化全生命周期监管支持高端医疗器械创新发展的举措(征求意见稿)》公开征求意见。该举措提出加快推进医用机器人、人工智能医疗器械、高端医学影像设备等领域的基础、通用标准和方法标准等制修订工作。作为医疗器械领域的重要企业，一脉阳光有望从这一政策中受益。
资金面上，南向资金对一脉阳光保持持续关注。数据显示，3月31日，南向资金增持一脉阳光424.70万股，已连续3日增持。截至3月31日收盘，港股通共持有一脉阳光914.90万股，占流通股3.67%。这一持续的资金流入可能为股价提供了支撑。值得注意的是，一脉阳光近5个交易日累计下跌21.15%，近20个交易日下跌55.68%，今日的反弹或与前期超跌有关。
