自4月7日反弹以来,指数已经连续上涨17周,共计81个交易日,累计最大涨幅达到32.92%。本周指数跌幅2.36%,周线收出一根中阴K线。

笔者上周文章的题目是《标普500上涨进入高风险区,短期谨防剧烈震荡》,在文章中运用多周期量化模型指标以及十几年历史数据回测,并结合当前宏观经济层面对金融市场的影响,提示下周指数还会创出新高,但由于指数处于技术超买+上涨时间周期末端,提醒投资者切勿被强势表象所迷惑,行情已进入高风险区;预测下周行情维持高位震荡结构,留意盘中剧烈波动,谨防单日大阴线快速杀跌。

从本周走势来看,周一小幅震荡,日线收出十字星;接下来两天连续收出阴线,跌幅不大;周四股价大幅高开并创出历史新高6427.02点后,开始缓慢下跌,收出一根高开低走的阴线,成交量明显放大,震荡幅度加大;周五股价跳空低开后持续下跌,当日收出一根低开低走的中阴线,日线留下跳空缺口。本周指数走势与笔者预测基本相符。

接下来,笔者从多维度层面分析当前指数所发生的变化:

(一)、量化模型信号分析:

1、周线视角(见图一):

①、动能量化模型:持续发出高位钝化信号,动能1号线运行方向从向上转为走平状态,能量柱与上周相比开始缩短。

②、情绪量化模型,指标仍然在处在高位,但是与上周相比减少。情绪1强度是0.54(取值范围0~10)左右,情绪2强度是1.99左右。

③、数字监测模型:上周收盘价是6388.64点,监测信号显示数字D(取值A~E),本周信号消失。如果接下来每周的收盘价均小于6388.64点,预示数字D见顶信号有效。震荡值0.73(取值范围0~1)。

④、顶峰信号:数值是4.65,指数仍在高风险区域。

2、日线视角(见图二):

①、动能量化模型:处在高位顶背离状态,周二动能1号线高位死叉动能2号线开始向下运行,两条信号线由粘合转为向下张口,能量(绿)柱逐步放大,预示做空力量加强。

②、情绪量化模型:指标脱离高位区,开始减小。

③、数字监控模型:周二监测信号显示高位数字9,随后三天信号消失,预示日线级别见顶(以收盘价为标准)信号有效。

④、顶峰信号:数值从周二最高值8.49降到周五2.13,说明指数开始调整。

⑤、量能方面:本周后两天成交量明显放大,呈现放量下跌状态,初现调整特征。

(二)、趋势时序与历史数据回测分析(图三):

①、回测数据区间:2009年3月6日2025年4月4日,共计840根周K线。

②、设定调整规则是:回调≤2周且跌幅≥5%,或者回调≥3周,回测数据中符合条件的调整共有52次。

③、统计历史数据寻找规律:每当指数从低点连续上涨16周后,出现调整的概率高达81%左右,并且出现大幅调整的概率较大。

④、从4月7日到7月25日,指数已经连续上涨16周时间,本周是第17周。指数在本周如期出现明显调整,静观行情后续走势。

二、下周行情预测:

1、笔者认为下周指数还会向下调整,重要支撑位在6147点附近,一次有效跌破的概率不大;指数调整到此处会有反弹,第一压力位在6300点附近,重要压力位在6247点附近。

2、指数盘中出现拉升时,借机调整仓位,切勿盲目追高,警惕指数形成二次顶的风险。

3、提醒投资者密切关注市场消息面的变化,关注大市值权重股的异动。

三、下周操作策略:

1、下周重点关注6147点的得失。若支撑有效,继续维持高位宽幅震荡;若有效跌破,则调整幅度加大,注意下跌风险。

1、中线仓位:笔者连续提示投资者,将21日均线作为止盈位。目前指数已经跌破,建议中线仓位减少到原有仓位的30%。个股亦可参照操作。

2、短线仓位:按照笔者给出的关键点位,设置好止损点,小仓位逢低做多,逢高做空。个股亦可参照操作

3、如果想得到更加精确的操作,可以把分析周期切换到小周期,例如60分钟或者120分钟周期。

以上各种模型是本人操作时遵守的交易规则,不构成任何买卖依据。个人观点,仅作参考。

SpaceX, OpenAI, Anthropic: The Three AI Giants Racing for IPO, Which One Is Worth Betting On?

SpaceX, OpenAI, and Anthropic are poised for historic IPOs within weeks, potentially raising a combined $180 billion—a sum exceeding the entire internet bubble's fundraising. The hosts of the Limitless Podcast argue this isn't just individual company financing but an unprecedented capital concentration for AI infrastructure, driven by an insatiable need for compute, data centers, power, and chips. SpaceX's IPO is notable for reportedly changing market index rules to allow faster inclusion, potentially funneling trillions in passive retirement funds into its stock, despite its unproven space-based data center business model. In contrast, Anthropic demonstrates explosive growth, with ARR reportedly hitting $45 billion and approaching profitability, fueled by strong enterprise adoption of products like Claude Code. Google's separate $80 billion raise highlights the immense capital pressure, even for giants. The discussion acknowledges bubble risks but leans optimistic. The hosts contend the massive spending is building essential physical infrastructure for the next technological era. A key bottleneck isn't capital but the real-world limits of chip manufacturing and construction speed. As long as demand for AI compute outstrips supply, this investment cycle represents a foundational build-out rather than a purely financial bubble. All three companies are seen as foundational bets on the future, with Anthropic often cited as the most immediately compelling due to its proven revenue trajectory.

From 'Old Guys' to 'New Favorites': How AI Is Revaluing Old Infrastructure from Dell to Nokia?

From "Vintage Tech" to "New AI Darlings": How AI Revalues Old Infrastructure One year ago, tech giants like Dell, Nokia, Cisco, and Western Data were seen as slow-growth, low-valuation stories, far from the AI spotlight dominated by players like Nvidia. Now, these legacy tech stocks are gaining market attention, sparking debate on whether this is genuine industry revaluation or a temporary narrative. As AI moves from model parameters to real-world data centers, the market is recognizing companies with proven delivery and infrastructure capabilities. This shift marks a change in the AI investment thesis: from pure model and GPU focus to the complex systems engineering required for deployment. Companies like Dell, HPE, and Corning are being revalued not for being "sexy" AI innovators, but for their decades of accumulated expertise in supply chains, enterprise delivery, and infrastructure—assets that have become critical in the AI buildout phase. The revaluation is unfolding across three key infrastructure lines: 1. **Servers & System Integration:** Dell and HPE are emerging as crucial system integrators or "general contractors" for AI data centers, translating GPU orders into complete, deployable server racks integrated with power, cooling, and networking. 2. **Networking & Connectivity:** AI's scale demands robust high-speed connections. Corning (fiber optics), Nokia (AI-RAN, 6G), and Cisco (data center switches) are gaining importance for enabling efficient data transfer within and between AI clusters. 3. **Storage:** Beyond high-speed memory (HBM/DRAM), the AI data explosion is driving demand for high-capacity hard drives (HDDs) from companies like Western Digital and Seagate to handle training data, logs, and cold storage cost-effectively. For this revaluation to be substantive and not just a narrative, three criteria are key: 1) Concrete AI-related order and revenue growth (e.g., Dell's AI server sales), 2) Upward revisions to company financial guidance, and 3) Sustainable improvements in profit quality, not just top-line revenue spikes. In essence, AI's transition to a real construction phase is re-pricing "old assets" against "new demand." The opportunity, however, is selective. Only those legacy firms that are demonstrably integrated into the capital expenditure chains of data center and enterprise AI deployment are likely to experience a true "logic re-rating" rather than just a temporary valuation bounce.

The Merger of Codex and ChatGPT Marks the Beginning of a Major Reshuffle in Programming Tools

OpenAI is shifting its strategic focus from ChatGPT to Codex, merging them along with the browser tool Atlas into a unified desktop super-app. This move signals an internal belief that Codex, originally a programming tool, represents the next evolution of AI more than conversational models like ChatGPT. Over the past year, Codex's weekly active users have surged past 5 million. The key distinction is that while ChatGPT answers questions, Codex executes tasks. Enterprises increasingly value this ability to get work done over simply receiving advice. Consequently, Codex is attracting professionals beyond developers, including analysts, bankers, marketers, and product managers. OpenAI's reorganization and increased investment in Codex stem from recognizing that the future of AI competition lies in execution capabilities, not just conversation. The company is launching role-specific plugins (e.g., for data analysis, sales, design) to transform Codex into a broad knowledge work platform that automates and redefines white-collar workflows. Beyond being a tool, Codex reflects OpenAI's ambition to redefine software. New features like "Sites"—which generates interactive websites from documents—and collaborative "Annotations" aim to create a paradigm where the AI understands the goal and handles the tools and steps, functioning more like a digital colleague than traditional software. The ultimate goal is a unified experience where the user cares only about the completed task.
