笔者上周文章的题目是《重要会议前夕,多看少动为主!》,在文章中依据多周期技术指标共振以及十几年历史数据回测,对本周指数做出预测。

在指数走势方面:

指数持续运行在5月2日之后形成的上升通道内,向上压力位在通道上轨附近,向下第一支撑位在通道下轨附近,第二支撑位在6300至6340点附近,重要支撑位在6200至6147点区域。

在操作策略方面:

1、美联储议息会议前夕,控制仓位,观望为主。

2、总仓位:多单持股仓位控制在50%左右;如果指数跌破生命线通道,需将仓位降到30%以下。

2、对于短线投资者,可以从仓位中拿出10%左右筹码,依据支撑、压力位做“短差”。

现在回顾本周的实际走势:

本周前两天指数振幅很小,观望气氛浓厚,分别收出两根涨跌幅为0.47%、-0.13%的小K线;周三美联储公布降息消息后,指数呈现“上蹿下跳”走势,最大跌幅为0.85%,触及本周最低价6551.15点,接近尾盘时指数又快速拉升,当日收出跌幅为0.10%、带长影线的阴“十字星”K线;周四收出一根涨幅为0.48%的小阳线;周五指数受市场利好消息刺激,指数高开高走,交易活跃,成交量较前几天明显放大,当日收出涨幅为0.49%的阳线,并且创出本周最高价6671.82点。

接下来,笔者通过多模型技术指标,分析当前指数发生的变化。

(一)、量化模型信号分析:

1、周线视角(见图一):

①、动能量化模型:由于受最近两周指数放量上涨影响,前几周发出的高位钝化信号已经消失,预示着在未来一段时间内动能顶背离不会形成。目前两条动能线加速上行,量能(红)柱重新增长。

模型提示下跌风险指数:中性

②、情绪量化模型:情绪1指标强度是6.22(取值范围0~10)左右,情绪2强度是5.62左右,顶峰信号指标是11.49。模型数据提示市场超买情绪加剧,指数面临宽幅震荡走势。

模型提示震荡风险指数:高

③、数字监测模型:本周没有信号显示。

2、日线视角(见图二):

①、动能量化模型:维持高位钝化状态,本周量能(红)柱逐步增大,特别是周五成交量明显放大,预示市场做多动能被重新点燃。在未来几个交易日,如果指数持续上涨,那么高位钝化信号有可能消失。

模型提示指数处于高位震荡状态,下跌风险指数:高

②、情绪量化模型:周五收盘后,情绪1指标强度是5.53,情绪2指标强度是3.2,顶峰信号指标是11.62。

模型提示下跌风险指数:高

③、数字监测模型:周五收盘后,监测信号是“C”(信号范围A~E)。

模型提示指数出现日线级别顶部拐点概率增加。

(二)、趋势时序与历史数据回测分析(图三):

1、笔者制定的数据回测模型:

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: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。

2、统计历史数据寻找规律:每当指数从低点连续上涨24周后,出现调整的概率大于95%。

3、在笔者回测的模型中,最大的一次上涨周期出现在2017年7月19日至2018年1月26日,指数连续上涨29周后,出现了一次跌幅为13.43%的下跌走势;还有两次分别是上涨26周之后出现大幅度调整。

4、从4月7日到9月19日,指数已连续上涨了24周。

二、下周行情预测:(09.22~09.26)

1、指数目前仍然运行在5月2日之后形成的上升通道内,警惕单日出现宽幅震荡走势。

2、指数向上压力位在通道上轨附近;向下第一支撑位在通道下轨附近,第二支撑位在6300至6340点附近,重要支撑位在6200至6147点区域。

三、下周操作策略:(09.22~09.26)

1、虽然指数在周线级别的动能高位钝化信号消失,但是在日线级别以及其他指标中,下跌风险指数依然比较高,而且上涨周期已经连续24周,所以建议投资者操作上保持谨慎态度。

2、总仓位:多单持股仓位增加到70%左右;如果指数跌破生命线通道,需将仓位降到30%以下。

2、对于短线投资者,可以从仓位中拿出20%左右筹码,依据支撑、压力位做“短差”。

3、短线操作时,建议把分析周期切换到60分钟或者120分钟的小周期,以便获取更精准的买卖点。

4、个股交易也可以参照上述操作策略。

四、经典案例分析:(只作为案例分析,不作为投资推荐)

1、微博(股票代码_WB):(多单)

微博(WB)周线图:

image.png

1、买入条件(多单):买入价是11.50~12.00美元,初始止损位是10.80美元,第一目标位是14.5~15美元,波段操作。

2、从周线形态来看,自2023年9月份以来,该股票持续在6.2~11.58美元之间做箱体震荡,持续时间大约两年左右。在本月初股价放量突破箱体上沿,下周如果缩量回踩箱体上沿不破,可以买入多单。

3、特别提示:对于波段操作,无论买入多单或者空单,建仓后立即设置初始止损位。当股价盈利5%时,立刻将止损位移动到成本线(即盈亏平衡点)附近,确保该笔交易不会亏损;当盈利达到10%时,将止损位上调至盈利5%的位置。此后,每当盈利增加5%时,止损位就同步上移相同幅度,以动态保护已实现利润。

4、上周笔者推荐的两支股票已经卖出,后续不再跟踪。其中欧林盈利卖出,美国航空止损卖出。

由于市场消息瞬息万变,笔者会适时调整操作策略及建议,投资者想及时获取最新信息,请关注下方链接。

U.S. National Debt Approaches $40 Trillion in 5 Months, Bitcoin Debate Gains Momentum

The US national debt has surged to nearly $40 trillion in just five months, the fastest trillion-dollar increase on record. The debt's growth has accelerated dramatically over time, from taking 192 years to reach the first $1 trillion in 1981 to adding the latest $1 trillion in only five months. The federal budget deficit for the fiscal year is already over $1.8 trillion, exceeding last year's total, and net interest payments on the debt have surpassed $1 trillion, now exceeding defense or Medicare spending. This rapid debt accumulation is fueling arguments within the cryptocurrency industry that Bitcoin serves as a hedge against government-backed currencies and fiscal irresponsibility. Proponents, including some lawmakers and industry leaders, argue Bitcoin could act as a "hard currency" fiscal control mechanism. Legislation has even been proposed for the Treasury to acquire Bitcoin to help reduce the national debt. The International Monetary Fund has warned that global public debt could hit 100% of world GDP by 2029 if current trends continue, with the US and China as primary drivers. Some analyses suggest a sovereign debt crisis could drive capital into alternative assets like Bitcoin, similar to past regional banking crises. However, skeptics point out that both Bitcoin and gold have fallen in price at times during 2026 despite record debt, indicating the depreciation hedge theory may operate over a much longer timeframe than short-term price action.

Technological Self-Reliance in China: A War from Lithography Machines to ABF Films

"China's Tech Independence: A Battle from Lithography Machines to ABF Film" In August 2026, Japan's Ajinomoto announced a 30% supply cut of ABF film to Chinese mainland clients, causing industry-wide shock and fears of price hikes and shortages in the semiconductor supply chain. That same year, Chinese company Lotus Holdings, known for its MSG business, acquired a small domestic ABF film startup for 103 million yuan, aiming to change this passive situation. ABF film is a core insulating material for advanced CPU, GPU, and AI chip packages. Ajinomoto, originally a food flavoring company, has monopolized over 95% of the global ABF film market for nearly 30 years, deriving its technology from byproducts of monosodium glutamate production. With AI chips consuming 5-10 times more ABF film than traditional chips, the supply-demand gap is widening. Ajinomoto's supply cut to China, where domestic ABF film production accounts for less than 5%, directly threatens the production of domestic high-end AI chips and their substrates. This incident highlights a crucial but often overlooked truth: the vulnerabilities in China's quest for technological self-reliance extend beyond headline areas like lithography machines to critical but seemingly minor components—insulating films, photoresists, electronic specialty gases, etc. The article frames China's tech independence as a multi-front war. While major breakthroughs have been achieved in chip design (e.g., Huawei's HiSilicon), foundry (e.g., SMIC), and memory chips (e.g., YMTC), countless smaller "Ajinomoto-style" chokepoints remain. Lotus Holdings' acquisition represents a significant shift: the battle is no longer fought only by tech giants but has become a collective, industry-wide effort involving companies from diverse backgrounds. Historically, external blockades have often spurred China's technological breakthroughs, as seen with Huawei's Kirin chips and YMTC's 3D NAND flash memory. Ajinomoto's supply cut, while a short-term challenge, may similarly catalyze domestic innovation in ABF film and other critical materials. The path to technological sovereignty is long and arduous, requiring sustained patience and investment to fill every gap in the complex supply chain. Lotus's move is not an immediate solution but a step towards that future, symbolizing a broader, relentless march toward independence.

The Great Ethereum "Rate Cut" Debate: Is Now the Golden Window for Staking with the Unconventional EIP-8363?

Ethereon's economic policy is under review as a new proposal, EIP-8363, sparks debate over potential "interest rate cuts" for staking. The unconventional proposal suggests gradually increasing the proportion of newly issued ETH rewards that are burned as the total staked ETH ratio rises, with issuance fully offset by burns once the ratio nears 50%. This would drive the protocol-level staking APR towards 0%, though validators would still earn transaction fees and MEV. This discussion emerges as staked ETH approaches 35% of supply, with the current protocol APR at ~2.6%. The core question is whether Ethereum needs to continue paying high issuance costs for marginal gains in security once sufficient participation is achieved. EIP-8363 aims to optimize security spending, but critics warn it could disproportionately impact solo stakers and potentially increase centralization among large, resilient operators. Paradoxically, this debate coincides with the Pectra upgrade (EIP-7251), which introduces native compounding for staking rewards, significantly improving capital efficiency for long-term holders. This creates a dual narrative: the protocol is making staking more efficient while reconsidering the economic incentive to stake. For long-term ETH holders, this environment may present a "time window" rather than a fixed-rate opportunity. While future APRs are expected to trend downward, starting staking earlier maximizes the compounding effect over time. The decision to stake depends on individual factors like investment horizon, liquidity needs, and risk tolerance regarding options like native validation, staking services, or liquid staking tokens (LSTs). The evolution from encouraging staking to managing its economic cost marks a new, mature phase for Ethereum's tokenomics, where the true value of staking may increasingly lie in the long-term power of compounding time.

Analyst States Bitcoin Remains Within $61-68k Range

An analyst stated that Bitcoin is likely to remain within a trading range of $61,000 to $68,000. According to Kirill Komalenkov, director of strategic communications at Bitbanker, Bitcoin continues to trade sideways amidst declining market volatility. He attributes its current stability to high market liquidity, with volatility near three-year lows. Komalenkov warned that sustained low activity carries risks of a price decline, with potential tests of support at $62,300 and $61,600. He suggested that major market players might use the current situation to accumulate liquidity, meaning any initial breakout from the range could be a false move. The analyst expects this sideways movement to persist until the latter part of August. Key factors for determining future market direction include fund flows into Exchange-Traded Funds (ETFs) and trader activity. However, Komalenkov noted a potential negative scenario for the second half of August, where heightened geopolitical tensions or hawkish rhetoric from US monetary authorities could trigger a new decline. In such a case, Bitcoin could fall to a range of $45,000–$50,000 by early autumn, which might form a new base for a potential market recovery later in the season. Separately, a Russian deputy finance minister recently announced that non-qualified investors in Russia will soon be allowed to legally purchase Bitcoin, Ethereum, and popular stablecoins, with an annual limit of 300,000 rubles per intermediary.
