(图三)

自4月7日反弹以来,指数已经连续上涨18周,共计86个交易日,累计最大涨幅达到32.92%。本周指数涨幅2.43%,周线收出一根中阳K线。

笔者上周文章的题目是《标普500调整大幕已拉开,盯紧关键点位》,在文章中从多周期技术分析视角以及十几年历史数据回测,提示本周指数调整到重要支撑位6147点附近时,会有强劲的反弹,一次有效跌破此点位的概率不大;反弹时第一压力位在6300点附近,重要压力位在6427点附近。强调因为日线已经跌破21日生命线,建议投资者在本周指数冲高时,借机降低中线仓位,并关注大市值权重股的异动。

现在从本周走势来看,周一指数以本周最低价6271.71点开盘后震荡上行,当日收出一根涨幅为1.47%的阳线;接下来4个交易日分别收出阴阳相间的日K线,并且5个交易日的低点不断抬高,周线收在重要点位6340点之上,形成的阳线实体几乎反包上周的阴线实体。本周实际走势与上周预测的相符,但是反弹力度比预测的要大。

接下来,笔者将从多周期技术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号线运行方向从走平又转为向上状态,能量柱与上周相比继续缩短,预示本周止跌后的反弹力度强劲,但是多方买入动能不足。

②、情绪量化模型,指标仍然处在高位,与上周相比增大。情绪1强度是4.08(取值范围0~10)左右,情绪2强度是3.45左右。

③、数字监测模型:在7月25日形成周线时,模型发出信号D(取值A~E),当时收盘价是6388.64点。上周收出阴线,见顶转折信号有效,但是本周收盘价大于6388.64点,预示周线级别中D转折信号失效。震荡值0.70(取值范围0~1)。

④、顶峰信号:数值是5.49,风险系数累计加大。

2、日线视角(见图二):

①、动能量化模型:处在高位顶背离状态,两条信号线形成的向下张口逐渐缩小,能量(绿)柱逐步缩短,预示本周指数止跌后每天的反弹力度逐步放大。

②、情绪量化模型:情绪1指标周五收盘后数值是4.36,又重新回到高位区;情绪2数值暂未进入高位区。

③、数字监控模型:7月29日监测信号显示转折数字9,判定标准是6389.77点。从7月30日至今,每个交易日的收盘价均小于6389.77点,预示日线级别见顶信号(以收盘价为标准)持续有效。

④、量能方面:本周每天成交量未见明显放大。

(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18周后,出现调整的概率高达84.6%左右,并且出现大幅调整的概率较大。

④、从4月7日到8月8日,指数已经连续上涨18周时间,从历史经验来看调整系数加大。

二、下周行情预测:(08.11~08.15)

1、笔者认为下周指数还会向上冲高,重要压力位在6427点附近;当指数向下调整时,第一支撑位在6300至6340点区域,重要支撑位在6147点附近。

2、从日线图中发现(见图二),从5月2日开始至今,指数沿着上升通道震荡上行,观察通道上下轨道的压力、支撑作用,重点关注通道下轨的得失。

3、从4月7日到8月8日,指数已经上涨86个交易日。在8月14日前后几天,指数进入变盘时间窗口。如果时间窗口生效,笔者认为指数向下变盘概率大。

4、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:(08.11~08.15)

1、下周重点关注6427点得失。若突破成功,则在此点位上方维持震荡结构,向上空间有限;若突破失败向下调整,则警惕在此处形成二次顶部的风险。

1、中线仓位:笔者已经建议投资者把中线仓位减少到原有仓位的30%。指数在本周经过大幅反弹之后,重新站上生命线,但是,由于指数距离前高6427点很近,并且日线级别即将进入时间敏感期,建议大家保持现有仓位,等明确方向后再操作。

2、短线仓位:设置好止损点,按照给出的关键点位以及通道上下轨道,逢高做空,逢低做多。

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。

Xiaomi MiMo's 99% Price Cut is Not Marketing! Luo Fuli Posts on X to Refute Critics

The price of Xiaomi's MiMo-V2.5 series API has been permanently reduced by up to 99%, specifically for the "Input (Cache Hit)" cost, which covers users re-reading historical context in long conversations. MiMo's head, Luo Fuli, published a detailed technical blog to clarify that this drastic price cut stems from genuine engineering breakthroughs, not a marketing stunt or a simple price war. The core of the achievement lies in six key engineering optimizations. First, the model architecture adopts a Hybrid Sliding Window Attention (SWA), reducing the memory footprint (KVCache) to 1/7th of a traditional model. Second, a dual-pool memory management system actually utilizes these savings, allowing a single GPU to handle over 5 times more concurrent users. Third, an upgraded prefix caching mechanism achieves a cache hit rate of 93-95% for repeated reads, meaning most such requests bypass GPU computation entirely. Fourth, a self-developed distributed cache (GCache) utilizes idle SSD space on existing GPU servers, eliminating additional storage costs. Fifth, an intelligent scheduling system (LLM-Router) efficiently routes requests to maximize cache reuse and performance. Sixth, Multi-Token Prediction (MTP) accelerates the model's text generation ("output") side. Together, these systemic optimizations dramatically lower the real computational cost per request, enabling the 99% price reduction for cached inputs while reportedly maintaining positive gross margins. Luo Fuli's disclosure aims to shift the narrative from "price war" to a demonstration of substantive AI engineering progress.

$26 Billion: An 'All-Chinese Team' Backs the World's Highest-Valued AI Programming Company

Cognition AI, the company behind the AI programmer "Devin," has raised over $1 billion in new funding at a valuation of $26 billion, just eight months after reaching a $10.2 billion valuation. The round was led by Lux Capital, General Catalyst, and 8VC. Founded by three young Chinese entrepreneurs with strong competitive programming backgrounds, Cognition initially gained fame with Devin, marketed as the world's first AI software engineer capable of handling tasks from start to finish. While its early demos were impressive, real-world usage revealed reliability and cost-effectiveness issues, leading to a significant price cut for Devin in 2025. A pivotal moment came when Cognition acquired the assets of AI IDE company Windsurf after a failed acquisition by OpenAI. This move gave Cognition a crucial developer-facing tool, allowing it to pursue a two-pronged strategy: Devin for autonomous task execution and Windsurf for integrated, collaborative coding within an IDE. This shift helped the company move away from the controversial "AI replacement" narrative towards a model of augmenting human engineers, particularly for repetitive or maintenance tasks. This strategic pivot is backed by strong commercial metrics. The company reports a 10x increase in enterprise usage this year, with an annual revenue run-rate of $492 million and a 50% month-over-month growth in enterprise Devin usage over the past six months. Its client list now includes major corporations like Goldman Sachs and Mercedes-Benz, as well as government agencies like NASA and the U.S. Army. Investors are betting on Cognition becoming a foundational piece of next-generation software engineering infrastructure, positioning it at the center of a hybrid future where AI agents and human developers work in tandem.

The Hottest 00s Generation on Wall Street

"Wall Street's Hottest '00s Phenom: The 25-Year-Old Fund Manager Who Bet on AI's 'Boring' Backbone" At just 25, Leopold Aschenbrenner, once fired by OpenAI, now runs a hedge fund worth $13.7 billion. His strategy? Betting against the consensus. While others chased AI chips, he invested early in the physical infrastructure powering the AI boom: electricity, data centers, and energy. Expelled from OpenAI's safety team in 2024, Aschenbrenner foresaw the coming bottleneck. He argued that AI progress would be limited not by algorithms, but by power, chip capacity, and space. Acting on this, he founded Situational Awareness LP to go long on these "old economy" assets. His bets have paid off spectacularly. His fund's assets soared from $255 million in late 2024 to $13.7 billion by Q1 2026. His portfolio is a direct reflection of his thesis: major long positions in fuel cell company Bloom Energy and data center/bitcoin mining firms like CleanSpark and Riot Platforms, which control critical land and power resources. Conversely, he holds massive put options against overheated semiconductor giants like NVIDIA and AMD. A notable exception was his bullish bet on storage company SanDisk, which surged ~160% in Q2. Aschenbrenner's vision is materializing. Tech giants like Amazon, Alphabet, and Meta are ramping up colossal capital expenditure on data centers. Global data center power consumption is projected to skyrocket, with AI accounting for over half by 2030. The demand for enabling technologies like optical fiber and modules is also exploding. His story underscores a fundamental truth of the AI era: the ethereal intelligence of algorithms rests on a very physical, heavy, and power-hungry foundation. The future is being built not just in code, but in concrete, copper, and kilowatts.

Review of Cathie Wood's Masterstroke Operation on Circle

A Recap of Cathie Wood's Masterful Trading in Circle's IPO This article analyzes the strategic moves made by ARK Invest's Cathie Wood around the IPO of Circle (CRCL). Despite her typical long-term, narrative-driven investment style, Wood executed a textbook "buy low, sell high" trade. Wood secured a core position of approximately 4.49 million shares at the $31 IPO price. The stock debuted at $69, surged to a high of $299 in June 2025 fueled by stablecoin regulatory news (the GENIUS Act), and then entered a prolonged decline. During this rally, ARK systematically sold around 1.7 million shares at an average price near $210, driven partly by internal fund rebalancing rules triggered by the stock's soaring weight. This move locked in substantial profits. As the stock later fell due to lockup expirations, new share issuance, and interest rate concerns—even dipping below $50—Wood began repurchasing shares. Starting in November 2025 around $86, she continued buying on the way down, eventually rebuilding her position to roughly the original size by Q1 2026. Key takeaways include: 1) Having a strong, independent long-term thesis (viewing Circle as critical digital dollar infrastructure). 2) Trading in tranches instead of trying to time exact tops or bottoms. 3) Maintaining strict position-sizing discipline, using rules to force profit-taking and preserve buying power. For most retail investors, chasing the dramatic "pop" at open is dangerous, as the subsequent 83% drawdown showed. Wood's success hinged on pre-IPO access, a clear investment thesis, and disciplined execution.

Sharplink CEO: Ethereum's Future is Unfolding Now

In an article titled "Sharplink CEO: Ethereum's Future is Unfolding," Joseph Chalom, a former BlackRock executive and current Sharplink CEO, argues that the current debates surrounding the Ethereum Foundation (EF) and ETH price miss the bigger picture. He asserts that Ethereum's long-term institutional adoption is secured by its foundational strengths: trust, security, and liquidity. Chalom highlights Ethereum's dominance in settling stablecoin value, tokenizing real-world assets (RWA), and facilitating high-value DeFi transactions as evidence of its winning position. He defends the Ethereum Foundation's focus on rigorous protocol development and a decade-long track record of major upgrades (The Merge, EIP-1559, Dencun, etc.), viewing its upcoming technical roadmap as the most ambitious in the industry. Contrary to critics, Chalom posits that Ethereum's decentralization and reliable neutrality are core strengths for institutional adoption, not weaknesses, as they prevent control by any single entity. Drawing a parallel to Amazon's early days, he suggests that ETH's intrinsic value is tied to the expansion of its network, which is poised for a step-change in transaction volume across stablecoins, RWAs, DeFi, and agentic finance. Chalom advocates for a "be greedy when others are fearful" approach, citing historical examples from Warren Buffett and his own experience at BlackRock during the crypto winter. He concludes that while the EF should remain focused on core protocol attributes (CROPS: Censorship Resistance, Capture Resistance, Open Source, Privacy, Security), there is a leadership gap in market outreach. Chalom calls for ecosystem participants, including Sharplink and other key players, to become more vocal advocates to support the coming institutional adoption supercycle, asserting that "Ethereum's future is unfolding now."
