2007年的"黄金十年"、2015年的"改革牛"，最终都以惨烈的价值回归告终。当下市场，同样的叙事正在 重演：机构投资者高喊"核心资产永续增长"，分析师们不断上调一些热门股票的目标价，散户们则怕错 过而恐慌性买入。 今年以来，A股市场无疑已处在一场牛市之中，特别是近期，股市几乎是天天上涨，身边人人都在讨论 股票赚钱，这种感觉确实像"幸福来敲门"。 然而，历史的经验一次又一次地告诉我们，在迎接送上门来的牛市幸福之时，我们需要冷静审视，并以 高度的智慧来认清，来的是真正的幸福？还是藏于幸福之中的巨大风险？ 不是说好的慢牛与长牛吗？ 在A股的历史上，从未进化出"慢牛""长牛"这一类动物，我们见过的都是"奔牛""疯牛"，然后就"慢 熊""长熊"。 这次不一样？！ 回望A股三十余年历程，每一个高峰都伴随着"这次不一样"的集体幻觉。 然而，至少在目前，我们得思考：上市公司的经营业绩在全面提升吗？国内经济的基本面上真能支撑一 次大牛市吗？…… 我认为，A股的熊长牛短是由其市场机制决定的，并不以我们投资人主观意愿而改变。在市场机制上， 经过了一轮新股IPO"注册制"的实验后，目前也基本回到了2015年的态势，A股炒壳、炒小、 ...

Core Viewpoint - The article highlights the strong demand for NVIDIA's H20 chips in the Chinese market, prompting the company to reconsider its production strategy and place urgent orders with TSMC to meet this demand [2][3]. Group 1: Market Demand and Strategy - NVIDIA had to change its strategy from relying solely on existing inventory to ordering 300,000 H20 chips from TSMC due to unexpectedly strong demand in China [2]. - Research firm SemiAnalysis reported that NVIDIA sold approximately 1 million H20 chips in 2024, indicating a significant market interest [2]. - The demand surge has led NVIDIA to contemplate restarting production, moving beyond just selling existing stock [2]. Group 2: Competitive Landscape - Despite the availability of alternative products from Huawei, NVIDIA remains popular in China, largely due to its CUDA ecosystem, which is difficult to replace [2]. - Chinese tech giants like Tencent, ByteDance, and Alibaba significantly increased their orders for H20 chips prior to the implementation of the export ban in April [2]. Group 3: Production and Financial Impact - NVIDIA's CEO Jensen Huang stated that the volume of H20 orders will determine whether production will restart, noting that supply chain reactivation would take about nine months [3]. - Following the April export ban, NVIDIA warned of a $5.5 billion inventory write-down and reported a loss of $15 billion in potential sales [3].
