美股那边，听说是不太稳当，那个科技股吧，可真是不得了，带着纳斯达克和标普往上冲，一天一个新高，脸上也有光，可是道琼斯就有点拉胯，死活起不 来，天天在那儿跌跌撞撞的，你说气不气人，所有人都觉得她以后不得了，可是就在那种环境下。谁能受得了。 欧股就更别提了，一片绿油油的，跌的，搞得人心惶惶的，英国的富时一百还好点儿，挣扎了一下，最后还是没起来，德国的还行，在那儿磨磨蹭蹭的，法 国的那个就惨了，直接往下跳，那跌的，看着都吓人。 不过，话说回来，我们A股好像有点盼头了，这休市的时候，外面的市场涨的还挺多，跌的少，算是个好兆头吧，而且，那个芯片算力什么的，最近好像特 别火，都在说A股要跟着一块儿涨，也不知道真的假的，反正大家都这么说，希望是真的吧。 大家都在想，这到底是怎么一回事。很多人看完这个故事，都会去想。 中概股 那个科技巨头，最近也是新闻可多了，特别是那个算力芯片，AMD算是出尽了风头，跟OPEN AI好像搞了个大项目，六吉瓦的订单，听着就让人兴奋，一 下子股价就暴涨，涨的那个劲头，真是没谁了，还有那个超微半导体，也跟着沾光，其他的半导体公司也都不错，除了英伟达，不知道怎么一回事，竟然还 跌了，有点奇怪，特斯拉 ...
