Daily Market Summary
1. Market Overview
The three major US indexes ended the week higher, supported by falling oil prices and hopes for US-China tariff cuts despite surging Treasury yields and inflation concerns. On September 25, the S&P500 rose +0.51% to 7,743.41, the Nasdaq Composite gained +0.48% to 27,068.72, and the Dow Jones climbed +0.93% (+478.64 points) to 51,828.62. The 10-year Treasury yield rose to 5.18% (near its highest since 2007) and the 30-year to 5.50%, but a $30 billion US-China tariff-cut agreement following President Xi Jinping's US visit and an AI chip rally, highlighted by AMD joining the $1 trillion market cap club, underpinned risk appetite. Korean markets are closed for the Chuseok holiday (9/24~9/25) and the weekend (9/26~9/27); on the last trading day, September 23, the KOSPI rose 63.01 points (+0.90%) to 7,080.92, and the KOSDAQ gained +1.11% to 836.27. The next trading day is Monday, September 28.
Key Takeaways
Macro: The 10-year Treasury yield jumped to 5.18%, its highest since 2007, but the US-China tariff-cut agreement and solid labor data (initial jobless claims at a 57-year low of 197,000) supported risk appetite, and the three major indexes finished the week higher.
Technical Scan: The TradingView MCP server was not connected in this session, so none of the scans, including NASDAQ top 10 gainers, candlestick patterns, crypto candlestick patterns, and volume breakouts, were collected. On a price basis, semiconductors (SMH +1.01%) and industrials (XLI +0.95%) led gains.
Korea: Markets are closed 9/24~9/27 for Chuseok; on the last trading day (9/23), the KOSPI closed at 7,080.92 (+0.90%), led by chipmakers and large caps. Samsung Electronics reclaimed the 270,000-won level on joint net buying by foreign investors, institutions, and other corporations.
Sectors: AMD topped $1 trillion in market cap, becoming the fourth member of the $1 trillion club after Nvidia, Broadcom, and Micron, while hyperscalers' corporate bond issuance to fund AI infrastructure has reached about $220 billion so far in 2026, already exceeding last year's full-year total.
Crypto: US spot bitcoin ETFs drew $2.4 billion in weekly inflows, turning cumulative year-to-date net flows positive for the first time. BTC is trading at $84,479.64 (+0.53%) as of 9/27.

Central Bank Watch
At its September 16 FOMC meeting, the Fed raised its benchmark rate by 25bp to 3.75~4.00%. It was the first hike since 2023 and the first decision under new Chair Kevin Warsh, appointed by President Trump. The move was driven by inflation resurging in the aftermath of the Iran war, and the dot plot pointed to the possibility of one more hike in 2026 (2027 projections were split among members: 8 for hikes, 6 for holds, and 4 for cuts). Intraday losses widened after Chair Warsh's hawkish remarks at the press conference.
On August 27, the BOK raised its base rate by 0.25 percentage point from 2.75% to 3.00%. It also sharply raised this year's growth forecast from 2.6% to 3.3%, citing rising exports and investment on the back of the semiconductor boom. The next meeting is October 22.

3. Top Headlines
Global
On Friday, September 25, the S&P500 rose 0.51% to 7,743.41, the Nasdaq Composite gained 0.48% to 27,068.72, and the Dow climbed 0.93% (+478.64 points) to 51,828.62. Although early-week jitters over surging Treasury yields and inflation weighed on markets, falling oil prices and hopes for easing Middle East tensions lifted all three major indexes to weekly gains.
Following President Xi Jinping's visit to Washington, the US and China agreed on eight items, including $30 billion in reciprocal tariff cuts and a new AI dialogue channel. The deal also includes a trade commission and a two-month extension of the trade truce that had been set to expire on November 10.
Treasury selling accelerated after the September PMI came in stronger than expected alongside signs of rising input prices paid by businesses. The 10-year yield neared its highest level since 2007, and the 30-year rose to 2004 levels.
US spot bitcoin ETFs took in $2.4 billion last week, turning cumulative year-to-date net flows positive for the first time. Ether ETFs also reversed from $140 million in outflows the prior week to $690 million in net inflows.
December gold futures stood at $4,382.50 an ounce, up more than 25% year-to-date. China's gold purchases through August topped 1,000 tons, already exceeding its full-year 2025 total, and gold ETFs drew $18 billion in August alone.
Bipartisan negotiations on a continuing resolution (CR) continue ahead of the September 30 federal budget deadline. With the last fiscal year having begun with the longest shutdown on record, there is incentive to reach a deal, but the odds of an agreement have actually declined in recent weeks.
Initial jobless claims for the week ended September 19 fell by 1,000 from the prior week to 197,000, below the forecast of 201,000. The four-week moving average also declined to 202,250.
Amazon, Alphabet, Meta, Oracle, Nvidia, and others have issued about $220 billion in investment-grade corporate bonds so far in 2026 to fund AI infrastructure investment. Capex at the four largest hyperscalers this year is estimated to have jumped 77% from a year earlier.
Korea
The KOSPI rose 63.01 points (0.90%) from the previous session to close at 7,080.92. Semiconductors and large caps drove the index higher, though early strength faded somewhat intraday in a strong-open, weak-close session.
The KOSDAQ opened at 830.71, rose as high as 838.32 intraday, and closed at 836.27. Strength in semiconductor equipment stocks and retail net buying drove the gain, while foreign investors and institutions were net sellers of 98.8 billion won and 30.6 billion won, respectively.
Samsung Electronics rallied back to the 270,000-won level. Amid expectations of strong chip exports, foreign investors, institutions, and other corporations were joint net buyers, pushing the shares higher.
Global newbuild orders for very large crude carriers (VLCCs) this year reached 217 vessels, or 32.6 million DWT, surpassing the 2006 record to set an all-time high. Korea's big three shipbuilders, including HD Korea Shipbuilding & Offshore Engineering, Samsung Heavy Industries, and Hanwha Ocean, continue to win high-priced tanker orders.
Under new management, Hanwha Aerospace and Hanwha Systems are expanding their business model around local production and technology transfer. Their export strategy targeting European demand for multi-layered air defense systems drew attention.
According to the National Intelligence Service, 107 cases of industrial technology leaks abroad were uncovered from 2021 to 2025, with semiconductor technology accounting for the largest share at 40 cases (about 37%). Concerns over leaks involving Samsung Electronics were reaffirmed.
Nvidia continues its run at a market cap of around 1,400 trillion won, powered by expanding global AI infrastructure investment despite the gap left by lost China sales. Expected benefits for Korea's HBM and memory supply chain were also noted.
4. Reddit Sentiment
Overall mood: neutral to mildly bullish, mixedOn investing and wallstreetbets, the hottest debate was over an AI
valuation bubble ("everyone knows it's overvalued, so why won't it crash?"), while StockMarket and economics highlighted
caution based on long-term rates at 20-year highs and slowing home prices. The backdrop includes geopolitical risks such as the escalation of the
Russia-Ukraine war (strikes on data centers), the campaign to isolate Iran, and US preparations for military intervention in Cuba. Key themes: the AI bubble debate,
surging long-term rates, bullish BTC memes, and persistent geopolitical risk.

Key Community Insights
A structural reading that the trigger for a bubble collapse would be the point when the top 10% of holders need cash resonated with users. Coupled with AMD joining the $1 trillion club and $220 billion in hyperscaler bond issuance, it suggests the capex-driven valuation debate is becoming real.
The point that the market is repricing rates on its own without Fed intervention matches yahoo-finance data showing the 10-year at 5.18% (highest since 2007). There is a risk that the credit repricing feeds into consumer and corporate funding costs with a lag.
Short warnings citing a lack of fundamentals coexisted with counterarguments that a high P/E could be justified if growth holds. An example of the overvaluation debate playing out at the single-stock level.
Cynical reactions to recurring defect issues dominated, and some users posted proof that they had exited positions beforehand. A case of renewed trust risk for an individual stock.

Reddit × Market Data Cross-Analysis
The AI valuation bubble warnings on r/investing and r/wallstreetbets remain at odds with actual price data. AI chip names such as SMH (+1.01%) and AMD (up 24% over five days after joining the $1 trillion club) continue to rally, and with the VIX low at 14.87, the market is not showing signs of a correction to match the community's wariness. By contrast, the long-term rate and housing concerns on r/StockMarket and r/economics align closely with yahoo-finance data (10-year at 5.18%, 30-year at 5.50%, both multi-year highs), a rare case where community sentiment and prices point in the same direction. The PLTR short debate is hard to check directly because single-stock price data were outside the scope of this collection.
5. YouTube Insights
Anthropic signed an $11.6 billion AI compute deal with Akamai (the largest in Akamai's history), and Microsoft shifted strategy to unify its consumer and business Copilot offerings, sending its shares higher after the announcement. Continued AI infrastructure investment was treated as a bullish signal.
Concerns were raised over Apple Watch's "Live Rewind" and "Siri Summary" features and Meta smart glasses' always-on listening and recording. The possible unveiling of a wearable device developed with Jony Ive at OpenAI's developer event next week and litigation with Apple were also mentioned.
This week the US 10-year Treasury yield hit 5.223%, its highest since June 2007, and the 30-year reached 5.501%, the highest since June 2004. The synchronized selloff in developed-market government bonds, extending to UK gilts, German bunds, and Japanese JGBs, was interpreted as a "regime shift" signal. Despite the bond market turmoil, the Nasdaq 100 rose 2.1%, showing a decoupling across asset classes.
The Revolut data breach was not a hack but a case of its "lawful request desk" being exploited with a forged Italian police request. KYC files of about 680 people (passport scans and full bitcoin transaction histories) were leaked, and the video pointed to a fundamental conflict between the EU AML rules' KYC data retention requirement and the GDPR's data minimization principle.
In the second episode of its Chuseok special stock consultation, the channel assessed the US-China summit as a symbolic deal on the level of "a two-month tariff delay plus two pandas," but read it positively in that there was no abrupt negative shock such as the feared sweeping concession to China. Citing the Philadelphia Semiconductor Index's +1.41%, it pointed to a rally led by Samsung Electronics, SK hynix, and materials, parts, and equipment names (PSK, Simmtech) and a possible KOSPI move to 7,324 in early October.
Common Outlook
Both Korea Economic TV videos read the absence of a sharp negative shock positively despite the US-China summit's lack of substantive results, and forecast a gradual rise in Korean equities led by semiconductors and materials, parts, and equipment. Bloomberg Technology also treated expanding AI infrastructure investment as a bullish signal in its Anthropic and Microsoft coverage.
Diverging Views
The Financial Times flagged the surge in global government bond yields as a warning sign while reporting a cross-asset decoupling in which the Nasdaq 100 actually rallied, highlighting rate-driven volatility risk that differs in tone from Korea Economic TV's optimistic outlook for Korean equities. Coin Bureau took a cautious stance, warning of regulatory and security risks in the crypto industry, and within Korea Economic TV the two panelists clearly disagreed over low-PBR policy beneficiaries (such as Hyundai Steel) — one saw the November low-PBR disclosures as momentum, while the other countered that structurally low profitability driven by China makes them unsuitable for long-term investment.
6. Investment Insights
Today's Key Themes
- AI chip capex supercycle continues — AMD topped $1 trillion in market cap to become the fourth member of the $1 trillion club, and Amazon, Alphabet, Meta, Oracle, Nvidia, and others have raised funds by issuing about $220 billion in investment-grade corporate bonds so far in 2026. Semiconductors, data centers, and power infrastructure broadly stand to benefit.
- Shift to a "higher for longer" rate regime — Following the 25bp hike at the September 16 FOMC (the first since 2023), the September 24 PMI surprise pushed the 10-year yield up to 5.18%. If the bond selloff persists, downward pressure could concentrate on rate-sensitive assets such as richly valued growth stocks and REITs (XLRE -0.22%).
- US-China trade easing supports risk appetite — The $30 billion tariff-cut agreement and new AI dialogue channel came with a two-month extension of the trade truce. The yuan strengthened modestly (USD/CNY -0.11%), and the deal contributed positively to Wall Street's weekly gains.
- Crypto fund flows reverse — Bitcoin ETFs drew $2.4 billion in weekly inflows, turning cumulative year-to-date net flows positive for the first time. However, security risks flagged by Coin Bureau, such as KYC data leaks and physical robberies (52 wrench attacks, up 33% year-over-year), persist.
- Geopolitical stalemate persists — The Russia-Ukraine war has escalated to attacks on data centers and internet networks, and Trump's rejection of Iran's plan to reopen Hormuz has revived Middle East risk. This is a source of short-term swings in oil prices, but the EIA's outlook for a gradual decline currently prevails.
Stocks/Sectors to Watch
AMD / Semiconductors (SMH)
Leading the AI chip rally after joining the $1 trillion market cap club. Late-October earnings from major chipmakers are the next checkpoint.
Samsung Electronics and SK hynix
Foreign and institutional net buying continues amid chip export expectations. SK hynix's earnings release (late October, revenue expected to exceed 80 trillion won) is the catalyst.
LG Innotek
Rising FC-BGA substrate orders point to improved earnings next year. Fourth-quarter earnings guidance is the checkpoint.
Simmtech
Memory module boards for HBM; expected beneficiary of Nvidia's next-generation Vera Rubin. Nvidia's next-generation GPU roadmap release is the checkpoint.
Gold (Precious Metals)
China's gold purchases through August topped 1,000 tons, exceeding its 2025 full-year total. The World Gold Council's monthly ETF flow data are the checkpoint.
Bitcoin ETFs
$2.4 billion in weekly net inflows turned year-to-date flows positive for the first time. The next weekly flow report will gauge whether the trend continues.
Risk Factors
- Federal government shutdown: Odds of a deal are declining ahead of the September 30 budget deadline. If it happens, releases from statistical agencies (jobs, CPI, etc.) would be delayed, leaving a gap in the Fed's data-dependent decision-making. Indicator to watch: progress in CR negotiations.
- Further rate hikes: The dot plot signals one more hike in 2026, and the market has priced in a 70% probability of an October hike. If realized, downward pressure could concentrate on richly valued growth stocks and the chip sector. Indicators to watch: the October FOMC dot plot and PCE inflation data.
- Prolonged Iran-Hormuz stalemate: A risk of renewed oil price gains; the pattern from the 12-day Israel-Iran war (June 2025), when oil spiked 8~12% before quickly normalizing, could repeat. Indicators to watch: intraday volatility in WTI and Brent, and diplomatic statements on Hormuz.
- French credit risk: Warnings comparing it to the 2010 Greek crisis emerged on r/economics. If realized, it could spill over to European government bonds and bank stocks. Indicator to watch: French government bond spreads.
- Home price correction: Signs of slowing demand and inventory buildup were spotted simultaneously on both r/RealEstate and r/economics. Indicators to watch: new home sales and mortgage rates.
7. Sector Analysis
Top Sector to Watch Today: Semiconductors (SMH +1.01%)
AMD surged 9% in a single day on September 21 to top $1 trillion in market cap for the first time, becoming the fourth member of the $1 trillion club after Nvidia, Broadcom, and Micron (five straight sessions of gains, up 24% cumulatively). The early success of Meta's new AI agent 'Muse' was cited as a catalyst for the rally, and AMD is up more than 180% year-to-date. Cumulative 2026 investment-grade bond issuance by Amazon, Alphabet, Meta, Oracle, and Nvidia reached about $220 billion, exceeding last year's full-year total and accelerating the funding of AI infrastructure investment. In Korea, both Korea Economic TV broadcasts named semiconductor and materials, parts, and equipment names, including Samsung Electronics (back at the 270,000-won level), SK hynix (up despite heavy foreign selling), PSK, LG Innotek, and Simmtech, as fourth-quarter market leaders.

Dominant Market Narrative
These 10 days saw two axes play out at once: "resurging inflation → monetary policy shift" and "risk appetite supported by the AI rally and trade easing." With inflation reviving in the aftermath of the Iran war, the Fed raised rates for the first time in three years (No. 1), and the strong PMI that followed pushed Treasury yields to their highest since 2007 (No. 2). These two events alone accounted for about half of the top 10's total Impact Score (49.0/93.35), showing that rates and bonds were the dominant theme of the period. At the same time, the AI chip rally, highlighted by AMD joining the $1 trillion club (No. 3), and tariff cuts stemming from Xi's US visit (No. 5) supported risk appetite, leaving the three major indexes higher for the week despite the surge in Treasury yields.
In terms of reinforcing relationships, No. 1 (FOMC hike) and No. 2 (PMI-driven yield surge) successively reinforced the "higher for longer" narrative, and No. 7 (solid labor data) supported hike expectations in the same direction. In terms of offsetting relationships, the risk-off pressure from the bond and rate axis was partly offset by the risk-on factors of No. 3 (AI rally) and No. 5 (tariff cuts), as actually observed in the weekly close on 9/25 (S&P +0.51%, Nasdaq +0.48%, Dow +0.93%). No. 4 (Iran-related geopolitics), a chain of events from the 9/22 UN speech to the 9/26 Hormuz rejection, repeatedly moved oil prices without a clear direction, reaffirming the stalemate.
Risk Scenarios
Valuation pressure from continued rate hikes
Probability: MediumThe dot plot signals one more hike in 2026, and markets have priced in a 70% chance of an October hike. If realized, downward pressure could concentrate on richly valued growth stocks and the chip sector.
Renewed oil price gains from a prolonged Iran-Hormuz stalemate
Probability: MediumIf the pattern of repeated negotiation breakdowns continues, a short-term spike could recur, like the pattern of the 12-day Israel-Iran war (June 2025, oil spiked 8~12% before quickly normalizing).
Data gap if a federal government shutdown occurs
Probability: Low to MediumIf it happens, delayed releases from statistical agencies would leave a gap in the Fed's data-dependent decision-making and could heighten policy uncertainty in markets.
Feedback risk between the AI rally and credit expansion
Probability: LowHyperscaler bond issuance ($220 billion+) is supporting the AI rally, but if large-scale credit expansion continues during a rate-hiking cycle, rising funding costs or a repricing of spreads could turn into valuation risk.
