TEBBIT U.S. Stocks Perpetual Daily Report｜September 19, 2026 (Saturday)
Data as of:2026/9/19 08:00 (UTC+8)
Corresponding U.S. stock trading date:2026/9/18
I. Overnight U.S. Stock Market
On September 18, the U.S. stock market as a whole showed mixed and volatile performance, with the three major indexes moving in different directions.
After the sharp rebound in the previous trading session, the market was once again affected by factors including the recovery in U.S. Treasury yields, persistently high crude oil prices, and the Federal Reserve’s subsequent policy path.
At the close:
Dow Jones Industrial Average: 51,682.64 points (down 95.40 points, or 0.18%)
S&P 500 Index: 7,650.50 points (up 12.74 points, or 0.17%)
Nasdaq Composite Index: 26,522.54 points (up 104.25 points, or 0.39%)
Technology and semiconductor stocks were relatively active, and the Nasdaq continued to post a modest gain; however, the Dow Jones Index edged lower under the influence of uncertainty surrounding interest rates and energy markets.
On September 18, the U.S. 10-year Treasury yield moved back toward 5%, briefly breaking above this important threshold during the session. Concerns about inflation and future interest-rate policy intensified again. Meanwhile, Brent crude remained above $100 per barrel, with energy prices remaining an important market variable.
On a weekly basis, the S&P 500 fell approximately 0.1% this week, the Dow Jones Index declined approximately 1.7%, while the Nasdaq Composite Index rose approximately 0.7%.

Data Notes
The closing reference prices and changes in this table are calculated uniformly using data for the corresponding stocks/ETFs during the regular U.S. stock trading session (**Eastern Time 09:30–16:00) on September 18, 2026**.
TEBBIT USDT perpetual contracts are continuously traded products. Actual execution prices, mark prices and settlement prices may be affected by market volatility before the market opens, after it closes and during market holidays, and may therefore differ from the corresponding spot prices.
**Important note:** The changes in this table refer to the changes in the corresponding U.S. stocks/ETFs during that day’s regular trading session, not the TEBBIT perpetual contracts’ own rolling 24-hour changes.

III. Market Observations
Market trading dynamics diverged significantly on September 18.
On September 17, the market primarily traded on:
Falling oil prices｜Declining yields｜Technology stock rebound｜Recovery in risk appetite
On September 18, the market began focusing again on:
Rising yields｜High oil prices｜Inflationary pressure｜The Federal Reserve’s subsequent rate-hike path
The U.S. 10-year Treasury yield moved back toward 5%, increasing the interest-rate sensitivity of high-valuation technology stocks. Meanwhile, crude oil remained near $100 per barrel, meaning the impact of energy prices on inflation has not yet fully subsided.
Therefore, short-term U.S. stock trading logic remains focused on:
Federal Reserve policy｜10-year Treasury yield｜Crude oil prices｜Inflation｜AI technology stocks
IV. Key Sector｜AI and Semiconductors
On September 18, the semiconductor sector remained a key market focus.
Among them, **SanDisk (SNDK)** performed particularly strongly, rising 10.99% on the day to close at $1,791.82, with trading volume also increasing significantly.
NVDA also rose 1.34% to close at $222.27, showing that the AI and semiconductor sectors remained relatively active amid market volatility.
Current areas of market focus in the AI industry chain mainly include:
AI computing demand
Data-centre capital expenditure
Demand for high-performance storage
AI server construction
Earnings growth of semiconductor companies
Among them:
NVDA
Focus on AI chips, data-centre demand and capital flows in the semiconductor sector.
SNDK
Focus on storage demand driven by AI data-centre construction, as well as price volatility following the recent sharp rise.
MSFT / AMZN
Focus on cloud computing, AI infrastructure and data-centre capital expenditure.
META
Focus on AI applications, advertising business and AI infrastructure investment.
V. Key News for September 19
1｜U.S. stocks fluctuate at elevated levels; Nasdaq continues to edge higher
On September 18, the Nasdaq Composite Index rose 0.39%, the S&P 500 rose 0.17%, while the Dow Jones Index fell 0.18%.
Compared with the strong rebound on September 17, market risk appetite became noticeably more cautious.
Technology stocks retained some support, but the 10-year Treasury yield moved back toward 5%, limiting further upside for the market.
2｜10-year Treasury yield moves back toward 5%
On September 18, the U.S. 10-year Treasury yield returned to around **5%**.
The rise in yields means that concerns about future inflation and further monetary tightening by the Federal Reserve have intensified again.
For technology stocks, key factors to monitor going forward include:
10-year Treasury yield｜Real interest rates｜U.S. Dollar Index｜Nasdaq performance
If yields continue to rise, valuation pressure on growth stocks may increase further.
3｜Crude oil prices remain elevated
On September 18, crude oil prices remained in a high range, with Brent crude still above $100 per barrel.
Oil prices have recently been affected by the situation in the Middle East and energy supply expectations, resulting in significant volatility.
Therefore, the following factors still warrant close attention:
Crude oil prices｜Situation in the Middle East｜Energy supply｜U.S. inflation
If energy prices continue to rise rapidly, concerns about inflation and interest-rate policy may increase again.
4｜SNDK surges; AI storage sector attracts attention
On September 18, SNDK rose 10.99%, making it one of the strongest performers among major technology stocks that day.
Recent performance shows that volatility in stocks related to storage and AI infrastructure has increased significantly.
Market attention is mainly focused on:
AI data-centre construction
High-performance storage demand
Server capital expenditure
AI infrastructure investment
SNDK has risen significantly in the short term, so its subsequent price volatility also warrants close attention.
5｜Quarterly derivatives expiration concludes
September 18 was the quarterly U.S. stock Triple Witching (when stock options, index options and index futures contracts expire simultaneously).
Market data indicates that related derivatives worth several trillion dollars expired that day. Concentrated expirations may increase trading volume and end-of-day fund rebalancing.
Therefore, the relatively rapid intraday movements in some individual stocks and indexes on September 18 do not necessarily represent the formation of a new trend.
After entering September 19, the market will gradually assess the underlying trading direction after the impact of quarterly-expiration-related funds subsides.
VI. Market Focus｜Leadership Changes at Berkshire Hathaway
On September 18, Berkshire Hathaway announced:
Warren Buffett will serve as honorary chairman
Howard Buffett will serve as chairman
Buffett will continue to serve as a company director. This change is part of Berkshire’s long-term succession arrangements.
The news was one of the major corporate stories in the U.S. capital markets on September 18 and also prompted further market attention to changes in the allocation of capital by large institutions and long-term investors.
VII. Market Focus for September 19
As September 19 is Saturday, the regular U.S. stock market is closed, there will be no regular U.S. spot trading session that day.
However, for U.S. stock perpetual contracts, attention should still be paid to:
Price movements of U.S. stock-related assets
Changes in crypto markets and global risk assets
Crude oil prices
U.S. Treasury yields
Weekend geopolitical news
AI and unexpected news in the technology industry
In particular, against the backdrop of this week’s Federal Reserve rate hike, elevated oil prices and the 10-year Treasury yield approaching 5%, weekend news may affect sentiment at the opening of U.S. stocks next week.
VIII. Core Market Logic for Next Week
This week, U.S. stocks experienced:
Federal Reserve rate hike
↓
Short-term pressure on U.S. stocks
↓
Falling oil prices and declining yields
↓
Strong rebound in technology stocks
↓
Yields move back toward 5%
↓
U.S. stocks re-enter a volatile phase
Therefore, next week’s market focus will remain centred on:
First｜The Federal Reserve’s subsequent interest-rate path
The market will further digest the policy signals following the September rate hike and monitor subsequent official remarks and economic data.
Second｜10-year Treasury yield
5% remains an important psychological threshold for the market.
Third｜Crude oil prices
Whether oil prices can continue to fall will directly affect the market’s assessment of inflation.
Fourth｜AI and semiconductors
NVDA, SNDK and other semiconductor assets have recently seen significantly greater volatility. AI capital expenditure and data-centre demand remain important market trading themes.
Fifth｜U.S. stock index performance
It is necessary to monitor whether the Nasdaq can remain strong, as well as the price performance of the S&P 500 near elevated levels.
