U.S. stocks continued to rise in the intraday session, with technology and semiconductors leading the gains, with Apple creating high-tech, AI and power chips strong; the impact of cloud failures was limited, and interest rates fell to support growth stocks, focusing on TSLA, INTC, NFLX, KO financial reports and CPI rhythm.

Bulls return to warming technology and semiconductors led gains in earnings and policy signals affected risk appetite

U.S. stocks continued to rebound intraday, with funds significantly flowing back to large technologies and semiconductors. The market was still biased towards risk-taking despite the tight earnings period and policy variables. Dow Jones, S & P and Nasdaq rose simultaneously, with the Philadelphia Semiconductor Index leading the gains. Investors focused on the actual impact of Apple's innovation, the strength of AI and power chips, and the brief cloud service accident on market sentiment. Although there is still uncertainty about the U.S. government shutdown and the delayed release of inflation data, the signal of cooling trade friction provides support, and overall risk appetite has temporarily gained the upper hand.

The index is rising, the plate is long, the atmosphere is spreading

The four major indexes rose simultaneously during the session, with the Dow Jones Industrial Average temporarily trading at 46,667.68, up 1.03%; the S & P 500 Index temporarily trading at 6,738.74, up 1.12%; the Nasdaq Composite Index temporarily trading at 23,018.19, up 1.49%; the Philadelphia Semiconductor Index temporarily trading at 6,908.59, up 1.93%. The main axis of buying is concentrated on large-scale technology, semiconductors and some theme stocks, driving the market's volume to warm up, short-term momentum from multiple parties extended upward, volatility indicators did not rise abnormally, and the mood was stable.

Apple hits a record high, seven heroes step forward to boost the market

Apple(Apple, AAPL) was motivated by positive reports on the sales prospects of the new generation of iPhone, and rose intraday and hit a record high. The seven giants joined forces to boost index performance. Nvidia(NVDA) rose 0.35% intraday, Tesla(Tesla, TSLA) rose 0.90%, Apple rose 4.31%, Meta Platforms(Facebook, META) rose 2.10%, Microsoft(MSFT) rose 0.78%, Alphabet (GOOGL) rose 1.17%, and Amazon(Amazon, AMZN) rose 1.23%. The return of funds to equity stocks has made the market structure healthier and driven up market risk appetite.

Semiconductor leads AI and power chips are strengthening simultaneously

The semiconductor family led the rise, benefiting from continued demand for AI computing and data centers, as well as the momentum of power components for automotive and industrial applications. Super Micro Computer(SMCI) rose 7.26% in intraday trading, ON Semiconductor(ON) rose 6.09%. Huida's trend was strong, and the Feich-half index significantly outperformed the broader market. The focus will then turn to the upcoming Intel(INTC) financial report and the outlook for the AI server supply chain. The market will mainly focus on early card retention.

Cloud accident interference limited technology, the main axis of the multi-head technology remains unchanged

A brief failure of Amazon's cloud services triggered a knock-on impact on some platforms, but Amazon's share price still rose, indicating that the market interpreted it as a one-time event. There has been no systematic sell-off among cloud and network service groups, and the focus is still back to revenue and product cycle momentum. The main axis of technology is maintained, and supply chains with large weights and benefiting from AI demand perform most steadily.

Individual stocks theme active rare earths and medical materials are the focus

Cleveland Cliffs (CLF) rose sharply driven by the idea of expanding its rare earth business. The rare earth concept was supported by positive ratings from securities firms, and related theme stocks strengthened. Cooper Companies(COO) reported that it sent shareholders in and promoted strategic options, driving the stock price higher, and Bausch + Lomb(BLCO) benefited simultaneously. Moderna(Modna, MRNA) rose 7.34%, as the strength of biomedical stocks added a highlight to the panel, indicating that funds are also laying out specific growth themes in addition to technology.

Software and storage pressure estimates and synchronous impact of message surface

Trends within technology diverged, with Oracle(Oracle, ORCL) down 4.71% and Seagate Technology(STX) down 4.04%, reflecting disputes over valuation sensitivity and demand visibility. The cloud, software and storage chains are susceptible to guidance and order-taking trends before and after the financial report. Short-term shocks have intensified but have not changed the main rising structure of the market.

Industry rotation clarifies that energy is soft and financial wait and see

Weaker oil prices have left energy stocks lagging behind. Financial groups are relatively wait-and-see under the influence of rising discussions on credit quality and downgrades of individual stocks. AppLovin (APP) has fallen due to news of regulatory investigations, and Progressive(PGR) has been under pressure due to downgrades. The rotation of market funds is dominated by growth-oriented weights and high-prosperity sub-themes, and differences are expressed between defense and prosperity sensitive groups.

Abnormal energy and replenishment kinetic energy intertwine short-term fluctuations heat up

Beyond Meat(BYND) rebounded violently under the influence of debt restructuring and technical factors. It surged before the market and followed by high volatility. The market interpreted it as a crisscross of short covering and chip swaps. Apple's growth is accompanied by increased volume. The strong upward trend of theme stocks and the strong downward trend of individual bearish stocks coexist, indicating that short-term funds are mainly driven by news and data.

Emotional risk factors related to trade cooling and government shutdown remain to be clarified

Policy signals are more neutral than more, and communication between finance and trade releases cooling messages, which helps reduce external uncertainties; the continued government shutdown has disrupted the pace of economic data release, but the market mostly regards it as short-term noise. The delayed release of CPI will affect the Federal Reserve's interpretation of the interest rate path, and the silence period before the meeting will allow the market to focus more on the company's own fundamentals and financial guidance.

Differences in interest rates and commodity trends, capital costs, moderate pressure

The yield on the 10-year U.S. government bond declined slightly and remained below 4%, while the yield on the 30-year bond was about 4.57%. The interest rate environment is more friendly to growth stocks in the short term. Gold prices rose by about 2% to US$4334 per ounce, and oil prices fell by about 1.5% to US$56 per barrel. The US dollar strengthened against the pound and weakened against the euro and the yen. Most mainstream crypto assets rose, and risk asset indicators were generally positive.

Futures index and volatility show optimism but remain wary before key data

Major stock index futures maintained a strong intraday pattern, while volatility indicators were stable and no sharp rise in safe-haven, indicating that the market is cautiously optimistic about short-term financial reports and policy messages. This week, we will focus on heavyweight financial reports such as Tesla(TSLA), Intel(INTC), Netflix(NFLX) and Coca-Cola(KO), as well as the latest explanations of asset quality from regional financial institutions, and continue to pay attention to the recovery of operations in cloud services and network infrastructure.

The continuity of structural bulls depends on the fundamentals verification

The intraday multi-position structure is led by weighted technology and semiconductors, with themes such as rare earth, biomedical and activist concepts rotating to drive the index upward. If the financial report and inflation data are in line with or better than expectations in the future, it will help support risk appetite; on the contrary, if guidance is conservative or policy uncertainty increases, fluctuations may intensify. At this stage, funds prefer highly certain growth and individual stocks with clear catalysis. The continuity of the market trend still needs to be continuously verified by fundamentals and data.
