TEBBIT US Stock Perpetual Daily Report｜September 15, 2026 (Tuesday)
Data as of:2026 September 15 08:00 (UTC+8)
Corresponding US stock trading date:2026 September 14
1. Overnight US Stock Market
On September 14, the US stock market weakened again, with all three major indices falling.
The market was mainly affected by factors including concerns over a slowdown in the **AI industry, renewed increases in international oil prices, and the US 10-year Treasury yield breaking above 5%**.
The artificial intelligence sector underwent a notable correction that day.Anthropic, OpenAI and other AI industry figures have recently discussed slowing the pace of AI development, prompting the market to reassess AI capital expenditure, chip demand and the AI investment payback period.
The semiconductor sector was one of the main sources of market pressure that day. NVIDIA fell by approximately 3.4%, while the Philadelphia Semiconductor Index fell nearly 6%. Some memory and AI infrastructure-related stocks declined even more sharply.
At the same time, tensions in the Middle East continued to affect energy markets.
Brent crude oil briefly approached 110 dollars/barrel during the session before ultimately falling back to approximately 105.68 dollars/barrel.WTI crude oil also moved back above approximately 100 dollars/barrel. Rising oil prices further strengthened market concerns over energy inflation and the Federal Reserve’s policy path.
The bond market also experienced notable 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-valuation growth stocks.
At the close:
Dow Jones Industrial Average: 52,421.20 points (down 152.09 points, or 0.29%)
S&P 500 Index: 7,619.98 points (down 37.00 points, or 0.48%)
Nasdaq Composite Index: 26,186.41 points (down 146.62 points, or 0.56%)
All three major indices ended their previous brief recovery and entered another period of range-bound adjustment.

3. Market Observations
On September 14, market trading dynamics changed significantly:
AI slowdown｜rising oil prices｜Treasury yields｜the Federal Reserve｜divergence among technology stocks
Previously, the market mainly traded around inflation data and changes in oil prices.
However, after entering this week, as the Federal Reserve’s September policy meeting officially began, market attention shifted further towards 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 currently 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-valuation technology stocks are once again facing valuation pressure.
At the same time, new sentiment-related disturbances emerged in the AI industry.
Some AI industry leaders recently expressed concerns about the pace of AI development and safety risks, prompting investors to reconsider:
AI investment be sustained?
Can data-centre capital expenditure continue to grow rapidly?
Can chip demand maintain its current growth rate?
AI companies’ future earnings cover their enormous infrastructure investments?
As a result, September 14 saw a clear **“repricing within technology stocks”**.
Some software and cybersecurity sectors performed relatively strongly, while chip and AI hardware sectors came under significant pressure.
The biggest change in the market at present is:
“The long-term AI thesis has not changed, but short-term valuations and capital-expenditure expectations are being repriced.”
4. Key Instrument｜NVDAUSDT
On September 14, NVIDIA became a key market focus.
NVIDIA closed at approximately 210.96 dollars, 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 nearly 6% that day, and NVIDIA, Broadcom, AMD and some memory-chip stocks all came under significant pressure.
The market’s current focus on NVDA is mainly centred on:
• AI chip demand continuing to grow rapidly
• Capital expenditure by hyperscale cloud providers
• The pace of data-centre construction
• Blackwell and demand for subsequent products
• AI infrastructure investment returns
• The movement of the US 10-year Treasury yield
In the short term, NVDA is being affected by both AI valuation adjustments + rising Treasury yields.
If the Federal Reserve sends a relatively dovish signal while oil prices decline, valuation pressure on technology stocks may ease.
Conversely, if interest rates continue to rise, short-term volatility in the AI sector may increase further.
5. Key News for September 15
1｜Federal Reserve meeting officially begins, bringing the week’s biggest variable
The Federal Reserve’s September policy meeting is being held this week, and the market is closely watching the interest-rate decision and subsequent policy guidance.
Recent inflation data has not shown clear signs of getting out of control, but renewed oil-price increases and rapidly rising 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 comments on the future interest-rate path.
If the policy signal is dovish, 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%, putting pressure on 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-valuation growth assets.
Therefore:
AI｜semiconductors｜software｜high-valuation technology stocks
remain the sectors most sensitive to interest-rate changes.
If the 10-year Treasury yield remains around 5%, the Nasdaq and high-valuation technology stocks may continue to face considerable volatility.
3｜Oil prices rise again, intensifying inflation concerns
Tensions in the Middle East continue to affect expectations for crude oil supply.
On September 14, Brent crude oil briefly approached 110 dollars/barrel during the session before ultimately falling back to approximately 105.68 dollars/barrel.
WTI crude oil moved back above 100 dollars/barrel.
The biggest impact of rising oil prices is not simply energy costs themselves; more importantly, they may affect inflation further through transportation, manufacturing and consumer spending.
The market is therefore continuing to focus on:
Middle East tensions｜Strait of Hormuz｜crude oil supply｜energy prices｜inflation expectations
If oil prices continue towards 110 dollars or even higher, pressure on the Federal Reserve’s policy 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 more than 3%, the Philadelphia Semiconductor Index fell nearly 6%, and some memory and AI infrastructure-related stocks declined even more sharply.
The market is not completely rejecting the long-term development thesis for AI, but is beginning to reassess:
AI capital expenditure too fast?
AI infrastructure investment be converted into profits, and when?
Can chip demand continue to maintain high growth?
As a result, the AI sector may shift in the short term from “simply chasing growth” to placing greater emphasis on profitability, cash flow and return on capital.
5｜Technology stocks show clear divergence
On September 14, not all major technology stocks declined.
Microsoft and Meta rose against the broader trend, while NVIDIA, Amazon and Tesla came under some pressure.
Specifically:
MSFT: up approximately 1.97%
META: up approximately 2.71%
NVDA: down approximately 3.36%
AMZN: down approximately 1.26%
TSLA: down approximately 0.76%
This means that the current market is not simply “selling technology stocks across the board”; rather, capital is being reallocated among different technology assets.
Investors are paying increasing attention to companies’ own profitability, AI commercialisation capabilities and cash-flow performance.
6. Key Focus for Today
On September 15, the US stock market is within the Federal Reserve policy meeting period.
Today, the market will focus on five key themes:
Federal Reserve rate decision｜Treasury yields｜crude oil prices｜AI sector｜technology-stock valuations
Key technology stocks to watch:
NVDA｜META｜MSFT｜AAPL｜AMZN｜TSLA｜SNDK
Specifically:
NVDA
Focus on whether the AI sector correction continues, as well as changes in the 10-year Treasury yield.
SNDK
Focus on sentiment in the memory-chip sector. On September 14, SNDK fell nearly 5%, with short-term volatility expanding significantly.
MSFT
Focus on AI capital expenditure, Azure cloud operations 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 performance.
AMZN
Focus on AWS, AI infrastructure and cloud-business growth.
TSLA
Focus on autonomous driving, Robotaxi and changes in overall risk appetite.
7. Market Outlook for Today
On September 15, the market enters a highly important time window.
The market has just experienced:
Rising oil prices → inflation concerns → rising Treasury yields → pressure on technology stocks
Now added to this are:
AI development concerns → repricing in the semiconductor sector
Short-term market volatility may therefore increase further.
The current market is mainly driven by three variables:
First: The Federal Reserve
If the policy signal is dovish, it may help technology stocks recover.
If the policy statement is more cautious, particularly if it emphasises the impact of oil prices on inflation, high-valuation technology stocks may remain under pressure.
Second: Crude Oil
If oil prices continue from around 105 dollars towards above 110 dollars, inflation concerns may intensify again.
If oil prices fall significantly, pressure on Treasury yields and growth stocks may ease.
Third: AI
AI remains one of the most important long-term investment themes in US stocks.
However, in the short term, the market is shifting from “AI growth” to “AI returns”.
As a result, the market may place greater emphasis on the complete chain of:
AI capital expenditure → chip demand → data-centre construction → corporate earnings → cash-flow returns
.
