一、一周行情回顾:(08.04~08.08)

周一开盘价6271.71点,并且产生本周最低价6271.71点,周五创出最高价6395.16点,最终收盘价6389.45点,周振幅123.45点,涨幅2.43%,周线收出一根阳K线,收盘价收在5周均线之上。

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。

Robotic GPT-3 Moment Shakes Silicon Valley: Zero Lines of Code, Learns Instantly, with Investments from Jensen Huang and Fei-Fei Li

Generalist AI's newly released robot foundation model GEN-1.5 is being hailed as the "GPT-3 moment" for embodied AI. The model demonstrates remarkable one-shot and few-shot learning capabilities in physical manipulation tasks. By watching a single 3-12 second demonstration video (physical prompting) without any training or code, the robot can attempt the task with a 59% average success rate across 10 tasks. With just 5 minutes of demonstration data and minimal fine-tuning (10 gradient steps), the success rate jumps to 83%. The most significant breakthrough is the emergence of spontaneous, improvisational problem-solving abilities not present in the training data. For instance, after learning to sweep blocks with a brush, the robot can adapt to use a banana similarly or switch to a completely new "scoop-and-pour" strategy when given a dustpan. Other emergent behaviors include removing obstacles, correcting errors, and spontaneously sorting objects. These capabilities stem from over 8 months of large-scale pre-training on physical interaction data, suggesting the existence of a Scaling Law for embodied intelligence—where model generalization improves with more data and training time. This approach drastically reduces the cost and expertise needed to teach robots new skills, potentially democratizing robot programming. The release coincides with a surge in the humanoid robotics sector, marked by events like the World Robot Conference and significant investments. While the demonstrated tasks are still relatively simple, the scaling trend and emergent behaviors point toward a future where general-purpose robot "brains" could be easily adapted to various hardware "bodies," reshaping the industry's competitive landscape.

Semiconductor Industry Sees a New Wave of Price Hikes, with STMicroelectronics, Maxscend and Others Increasing Prices Intensively

The semiconductor industry is experiencing a new wave of price increases driven by supply-demand dynamics and rising costs. Throughout August, multiple international and domestic semiconductor companies have issued price adjustment notices to clients, with a focus on analog and RF chips. Key companies adjusting prices include STMicroelectronics, which is implementing its third price hike in 2026 effective August 23, citing sustained demand pressure and rising costs across the supply chain. Analog Devices, Inc. (ADI) has also announced a second price increase for 2026, effective September 13, due to "unprecedented" demand growth and escalating manufacturing costs. In China, RF chip leader Zhuosheng Microelectronics issued a price adjustment notice for its full RF product line, effective September 1, its first hike this year, attributing it to rising raw material and foundry costs. Additionally, Chinese MCU manufacturer Nations Technologies announced a 10-20% price increase for some products from October 1. This new round of price hikes has shifted its focus to mature process nodes (e.g., analog, RF, power, MCUs), partly due to AI computing demand consuming 8-inch wafer capacity. This contrasts with the first half of 2026, when the surge was led by AI memory chips like HBM and server DRAM. Analysts note that the long lead time for expanding analog/power semiconductor capacity (18-24 months) may sustain price resilience in the short term. However, downstream manufacturers' cost tolerance and fluctuating global demand could become constraints, potentially limiting further significant price increases. Companies have linked the hikes to ensuring future supply stability by funding capacity expansion.
