Rating historyChinese only
- Buy内存接口是全球三家寡头的卡点环节，存储周期向上；现价高于 163.42–169.20 入场区间约 5%，以止损 155.66 为界分批
- Buy略高于候补区间 163.42–169.20；美光 fPE 4 说明存储周期分歧，但澜起的接口芯片是 AI 服务器的「过路费」，盈利 +69.6%；止损 155.66
- Buy现价在候补入场区 163.42–169.20 内，高利润率 + 零负债，缩量回调；分批，止损 155.66
- Buy候补池标的（10-17 入池，入场区间 163.42–169.20，止损 155.66），评级与上次一致；49.9% 净利率证明了接口芯片的定价权，DDR5 渗透率提升是跨周期逻辑；现价在入场区间上沿，守 155.66
- Buy未变——收盘在入场上沿 169.20，回踩 163–166 分批；它是 A 股与美光存储周期关联度最高的标的，前瞻 43 倍对应 55% 增速
- Buy周五逆势 +3.8%，内存接口芯片随 DDR5 渗透与服务器出货双升，fPE 43 倍对应净利 +55% 合理；是国产算力里现金流最好的，小仓
