智通财经APP获悉，广发证券发布研报称，RAG架构为大模型提供长期记忆，企业和个性化需求推动了 对RAG存储需求的增长。AI推理中的RAG向量数据库存储介质正在从"内存参与检索"向"全SSD存储架 构"过渡，推动高带宽、大容量SSD的需求将持续增加。建议关注产业链核心受益标的。 火山引擎TOSVectors开启向量存储新范式，对SSD需求提高 根据火山引擎开发者社区公众号，TOS推出Vector Bucket，该架构采用字节自研的Cloud-Native向量索 引库Kiwi与多层级本地缓存协同架构(涵盖DRAM、SSD与远程对象存储)。在大规模、长周期存储和低 频查询的场景下，该架构不仅满足高/低频数据的分层需求，而且显著降低企业大规模使用向量数据的 门槛。TOSVector与火山引擎高性能向量数据库、火山AI agent等产品深度协同，以交互型Agent场景来 看，将高频访问的记忆(如用户的核心偏好、近期的任务执行结果等)存放在向量数据库中，实现毫秒级 的高频检索;将低频访问的记忆(如半年前的交互记录或历史执行结果)沉淀到TOSVector中，允许秒级延 迟，以此换取更低的存储成本和更广阔的记忆空间;以处理 ...

中证报中证网讯(记者王鹤静)12月30日晚间，广发证券发展研究中心所长助理、首席策略分析师刘晨明 在中国证券报"金牛来了"直播间分享了其对A股投资的新思考。 刘晨明认为，A股和港股的盈利研判框架需重大调整。结合当前市场环境来看，在地产、基建、内需消 费等传统经济板块体感未有改善的情况下，A股非金融板块的ROE实现了连续三个季度的企稳。A股历 史上还没有出现过连续三年"提估值"的情况，在2024年至2025年连续两年估值正贡献的情况下，2026年 估值演绎能否打破历史规模值得关注。 刘晨明提出，A股连续三年行业涨幅排名前五的案例历史上只出现过一次，即2016年至2020年的食品饮 料行业，其它行业都无法连续领涨三年，2026年通信和电子行业的表现能否打破行业涨跌"事不过三"的 规律值得关注。今年电子行业的机构持仓达到历史单个行业的上限，也打破了所谓"20%持仓即见 顶"的"魔咒"，TMT板块持仓比例已超过当年的"茅指数"。每一次产业周期牛市中TMT成交占比都会突 破历史上限，今年DeepSeek时期TMT成交额占比突破历史。此外，继黄金2024年一季度突破历史周期 上沿后，今年LME铜价也突破了历史上每一轮涨价 ...

刘晨明认为，投资黄金的关键在于"拿得住"。为克服人性弱点并规避择时风险，定投是一个很好的参与 方式。通过分批买入平摊成本，在低位积累筹码，通过定投以时间换空间，耐心等待每一次脉冲带来的 资产跃升，才是稳健的取胜之道。 中证报中证网讯(记者王鹤静)12月30日晚间，广发证券发展研究中心所长助理、首席策略分析师刘晨明 在中国证券报"金牛来了"直播间分享了对于黄金投资的思考。 刘晨明提示，投资者需要认清，黄金主要呈现急涨慢跌的走势特征，金价往往在经历漫长的盘整或缓慢 阴跌后，才会出现短时间的脉冲式拉升。这意味着市场大部分时间是枯燥甚至煎熬的，如果试图频繁做 波段，可能极易"卖飞"错过主升浪。 ...
