今天市场有个显而易见的特点，一方面是白银、黄金为代表的贵金属大涨，另一方面则是科技板块。 这两个层面其实各有逻辑，先说贵金属大涨，比如说白银主要是需求层面紧张，加上美联储12月份降息的预期，更为关键的是，大家对明年的降息幅度有更 为乐观的预期，所以国际金价已经朝着4300美元冲击了，简单说就是对美元货币宽松的超预期； 再来说大科技，上周五美股的科技股继续上涨，而这是在英伟达下跌，以及谷歌涨速变缓的情况下，说明全球科技依然是受到资金重视的，这点很好的传递 到了今天的A股。 当然了还有一层比较重要的逻辑，就是中证A50指数成分股调整，市场热度比较高的中际旭创被纳入，这引发了市场的极大关注，今天该股盘中大涨5%大 概率与此有关，问题的核心在于带动了整个科技股，无论是芯片龙头寒武纪，还是芯片指数，包括人工智能指数，普遍涨幅在2%左右。 还有一点，就是在上周的时候大家比较关心成交金额，而这个现象在今天也似乎出现了逆转，比如说收盘时两市成交了1.87万亿元，直接比上个交易日多出 了2881亿元，这说明经过了上周的上涨之后，市场向多的氛围越来越明显，如果明天继续放量，两市成交就重新站上了2万亿了，可以说就比较安全了。 明天 ...
