Savicoin US Stock Perpetual Daily｜September 15, 2026 (Tuesday UTC+8)

Data as of: September 15, 2026, 08:00 (UTC+8)
Corresponding US stock trading date: September 14, 2026

I. Overnight US Stocks

On September 14, the US stock market weakened again, with all three major indices declining.

The market was primarily affected by factors including “concerns about a slowdown in the AI industry, a renewed rise in international oil prices, and the US 10-year Treasury yield breaking above 5%”.

On the day, the artificial intelligence sector underwent a significant correction. Recent discussions among AI industry figures, including those from Anthropic and OpenAI, about slowing the pace of AI development prompted the market to reassess AI capital expenditure, chip demand, and the return cycle for AI investments.

The semiconductor sector was one of the main sources of pressure on the market that day. NVIDIA fell approximately 3.4%, the Philadelphia Semiconductor Index declined by nearly 6%, and some memory and AI infrastructure-related stocks fell even more sharply.

Meanwhile, the situation in the Middle East continued to affect energy markets.

Brent crude briefly approached $110 per barrel during the session before eventually falling back to approximately $105.68 per barrel; WTI crude also moved back to around $100 per barrel. Rising oil prices further intensified market concerns about energy inflation and the Federal Reserve’s policy path.

The bond market also experienced significant volatility. The US 10-year Treasury yield briefly broke above 5% during the session, its first such move since 2023. The high-interest-rate environment further pressured high-valued growth stocks.

At the close:

Dow Jones Industrial Average:52,421.20(-0.29%)

S&P500:7,619.98(-0.48%)

Nasdaq Composite Index:26,186.41(-0.56%)

All three major indices ended their previous brief recovery and once again entered a period of volatility and adjustment.

III. Market Observations

On September 14, market trading dynamics changed significantly:

AI slowdown｜Oil prices rising｜Treasury yields｜Federal Reserve｜Technology stock divergence

Previously, the market was primarily trading around inflation data and changes in oil prices.

However, as the week began and the Federal Reserve’s September policy meeting officially commenced, market attention shifted further toward interest-rate policy and AI asset valuations.

On the one hand, the market remains highly focused on the Federal Reserve’s policy decision this week. Interest-rate markets still assign a relatively high probability to a 25-basis-point adjustment. On the other hand, the 10-year Treasury yield breaking above 5% means that high-valued technology stocks are once again facing valuation pressure.

At the same time, new sentiment-driven disruptions emerged in the AI industry.

Concerns recently raised by some AI industry leaders about the pace of AI development and safety risks have led investors to reconsider:

Can AI investment be sustained?

Can data centre capital expenditure continue to grow rapidly?

Can chip demand maintain its current growth rate?

Can future AI company profits cover enormous infrastructure investments?

As a result, September 14 saw a significant “repricing within technology stocks”.

Some sectors, such as software and cybersecurity, performed relatively strongly, while chip and AI hardware stocks faced considerable pressure.

The biggest change in the market is currently:

“The long-term AI thesis has not changed, but short-term valuations and capital expenditure expectations are being repriced.”

IV. Key Underlying｜NVDAUSDT

On September 14, NVIDIA became a key focus of the market.

NVIDIA closed at approximately $210.96 that day, down approximately 3.36%.

Recent discussions in the AI industry about slowing the pace of development directly affected risk appetite in the semiconductor sector. The Philadelphia Semiconductor Index fell by nearly 6% that day, while NVIDIA, Broadcom, AMD, and some memory chip stocks all came under significant pressure.

Market attention on NVDA is currently focused mainly on:

• Whether AI chip demand will continue to grow rapidly
• Capital expenditure by hyperscale cloud providers
• The pace of data centre construction
• Demand for Blackwell and subsequent products
• Returns on AI infrastructure investment
• The movement of the US 10-year Treasury yield

In the short term, NVDA is being affected by both AI valuation adjustments and rising Treasury yields.

If the Federal Reserve signals a relatively accommodative stance while oil prices fall, valuation pressure on technology stocks may ease.

Conversely, if interest rates continue to rise, short-term volatility in the AI sector may increase further.

V. Key News for September 15

1｜Federal Reserve meeting officially begins, presenting the week’s biggest variable

The Federal Reserve’s September policy meeting is taking place this week. The market is currently highly focused on the interest-rate decision and subsequent policy guidance.

Recent inflation data has not shown significant signs of getting out of control. However, the renewed rise in oil prices and rapid increase in long-term Treasury yields have made assessments of the future interest-rate path more complicated.

The market is currently focused on:

Interest-rate decision｜Dot plot｜Economic projections｜Inflation projections｜Employment projections｜Policy statement

Particular attention should be paid to the Federal Reserve’s statements regarding the future interest-rate path.

If the policy signal is accommodative, growth stocks may receive support.

If the Federal Reserve emphasises energy prices and inflation risks, Treasury yields may remain elevated.

2｜10-year Treasury yield breaks above 5%, pressuring technology stock valuations

On September 14, the US 10-year Treasury yield briefly broke above 5% during the session, its first such move since 2023.

Rising long-term Treasury yields increase overall funding costs while reducing the valuation appeal of high-valued growth assets.

Therefore:

AI｜Semiconductors｜Software｜High-valued technology stocks

remain the sectors most sensitive to interest-rate changes.

If the 10-year Treasury yield remains around 5%, the Nasdaq and high-valued technology stocks may continue to face significant volatility.

3｜Oil prices rise again, intensifying inflation concerns

The situation in the Middle East continues to affect expectations for crude oil supplies.

On September 14, Brent crude briefly approached $110 per barrel during the session before eventually falling back to approximately $105.68 per barrel.

WTI crude moved back above $100 per barrel.

The greatest impact of rising oil prices is not limited to energy costs themselves. More importantly, they may further affect inflation through transportation, manufacturing, and consumption.

The market is therefore continuing to focus on:

Middle East situation｜Strait of Hormuz｜Crude oil supply｜Energy prices｜Inflation expectations

If oil prices continue moving towards $110 or higher, pressure on the Federal Reserve may increase further.

4｜AI sector undergoes correction, with semiconductors becoming the main source of pressure

On September 14, AI and semiconductor stocks weakened significantly.

NVIDIA fell by more than 3%, the Philadelphia Semiconductor Index declined by nearly 6%, and some memory and AI infrastructure-related stocks fell even more sharply.

The market is not completely rejecting the long-term development thesis for AI. Instead, it has begun to reassess:

Is AI capital expenditure growing too quickly?

When will AI infrastructure investment translate into profits?

Can chip demand continue to maintain high growth?

As a result, the AI sector may shift in the short term from simply “pursuing growth” to placing greater emphasis on profitability, cash flow, and return on capital.

5｜Technology stocks show clear divergence

On September 14, not all large technology stocks declined.

Microsoft and Meta rose against the trend, while NVIDIA, Amazon, and Tesla came under some pressure.

Among them:

MSFT: up approximately 1.97%

META: up approximately 2.71%

NVDA: down approximately 3.36%

AMZN: down approximately 1.26%

TSLA: down approximately -1.72%

This means that the current market is not simply experiencing a “broad sell-off in technology stocks”. Instead, capital is being reallocated among different technology assets.

Investors are beginning to focus more on companies’ own profitability, AI commercialisation capabilities, and cash flow performance.

VI. Key Points to Watch Today

On September 15, US stocks enter the period of the Federal Reserve policy meeting.

The market will focus on the following five themes today:

Federal Reserve rate decision｜Treasury yields｜Crude oil prices｜AI sector｜Technology stock valuations

Technology stocks to watch:

NVDA｜META｜MSFT｜AAPL｜AMZN｜TSLA｜SNDK

NVDA

Focus on whether the correction in the AI sector continues and on changes in the 10-year Treasury yield.

SNDK

Focus on sentiment in the memory chip sector. SNDK fell by nearly 5% on September 14, with short-term volatility increasing significantly.

MSFT

Focus on AI capital expenditure, the Azure cloud business, and enterprise AI demand.

META

Focus on AI commercialisation, the advertising business, and AI infrastructure investment.

AAPL

Continue to monitor the new product cycle and market expectations for subsequent iPhone sales.

AMZN

Focus on AWS, AI infrastructure, and cloud business growth.

TSLA

Focus on autonomous driving, Robotaxi, and changes in overall risk appetite.

VII. Market Outlook for Today

On September 15, the market enters a highly critical time window.

The market has just experienced:

Rising oil prices → Inflation concerns → Rising Treasury yields → Pressure on technology stocks

It is now also facing:

Concerns about the pace of AI development → Repricing of the semiconductor sector

Therefore, short-term market volatility may increase further.

The market is currently focused primarily on three variables:

First: The Federal Reserve

If the policy signal is accommodative, it may help technology stocks recover.

If the policy guidance is more cautious, particularly if it emphasises the impact of oil prices on inflation, high-valued technology stocks may remain under pressure.

Second: Crude oil

If oil prices continue moving from around $105 to above $110, inflation concerns may intensify again.

If oil prices fall significantly, pressure on Treasury yields and growth stocks may ease.

Third: AI

The AI industry remains one of the most important long-term investment themes in US stocks.

However, in the short term, the market has begun shifting from “AI growth” to “AI returns”.

Therefore, the market may place greater emphasis on:

AI capital expenditure → Chip demand → Data centre construction → Corporate profits → Cash flow returns

as a complete chain.
