Japan's Nikkei 225 closed at 64,075.42 on October 20, down 841.28 points (1.30%), as selling hit semiconductor and AI-related shares and rising oil prices fed inflation worries. The TOPIX fell 58.27 points (1.43%) to 4,009.21 on about 2.15 billion shares traded, and the decline spread to transport and communications stocks even after U.S. chip and AI shares rebounded overnight. Resonac fell 10.80%, Fujikura 6.47% and SUMCO 6.30%, while Toho, Terumo and Olympus gained. Brent crude around $110 a barrel added cost pressure on Japan, an economy heavily dependent on imported energy. The yen moved toward 158.1 per dollar after a strong 20-year government bond auction pushed its yield down about six basis points to 3.71%, as investors looked ahead to a Bank of Japan policy meeting on October 30.

- Japan logs 3 . 4 bln USD trade deficit in September - Xinhua
Japan recorded a September trade deficit of 536.6 billion yen (about 3.4 billion U.S. dollars), its fifth consecutive monthly deficit, according to Ministry of Finance data. Exports rose 16.7% year on year, extending growth to a 13th straight month on strong demand for semiconductors and AI-related products, while imports grew 18.9%, slowing from 28.0% in August partly due to lower crude oil arrivals. The deficit narrowed from 1.11 trillion yen in August. For the first half of fiscal 2026, covering April through September, the deficit reached 2.8 trillion yen, nearly double a year earlier, as surging crude prices amid Middle East turmoil raised import costs.
- Asian shares mostly decline after AI stocks lead a rebound on Wall Street
Most Asian shares fell in cautious trading on Tuesday, even after AI-related stocks rebounded on Wall Street, while other sectors remained shaky and oil prices stayed high. Japan's Nikkei 225 dropped 0.6% in early trading to 64,512.35, South Korea's Kospi fell 2.8% to 5,605.31, and Australia's S&P/ASX 200 lost 0.8%. On Wall Street, the S&P 500 gained 0.4% to 7,690.73 and the Nasdaq composite rose 1.1%, but most stocks outside AI and tech declined, and the Dow slipped 0.1%. The 10-year Treasury yield climbed to 5.14%, while U.S. crude rose to $103.50 a barrel and Brent to $109.47, as uncertainty over when the energy industry can return to normal amid the war with Iran keeps oil prices elevated.
- Nasdaq climbs as US chip and AI - linked stocks bounce back
The Nasdaq Composite rose about 1% on Oct 19 as investors returned to chip and AI-related stocks after last week's heavy selloff, ahead of key earnings reports. The Philadelphia Semiconductor Index closed up 1.6%, snapping an eight-day losing streak in which it fell about 15.7%, its longest run of declines since October 2008. Concerns that higher interest rates could curb AI infrastructure investment have weighed on chipmakers and data centre operators. US crude futures settled up 2.2% at US$103.66 a barrel after Iran-aligned Houthi attacks on a Yemeni military training camp and Saudi energy facilities. Amazon.com rose 5% after Morgan Stanley named it a 'top pick', while CoreWeave had plunged more than 25% last week over worries about its $50 billion debt load.
- AI trade reversal pierces Asia star picks - and - shovels stocks
A selloff in US tech stocks is raising concerns that rising financing costs could curb AI infrastructure spending, threatening earnings across Asia's chip supply chain. Oil surged to $110 a barrel, stoking inflation worries, while an eight-session rout in US semiconductor shares, the longest since 2008, cut roughly 16% from the sector benchmark. A Goldman Sachs basket of regional AI hardware stocks fell 11% last week. Nan Ya Plastics dropped 12% from a record high, Unimicron fell 14% and Samsung Electro-Mechanics plunged 23%. CoreWeave's bonds sank to levels signaling distress, and Gartner warned more than $3.5 trillion of AI infrastructure spending could be impaired by 2030. TSMC, Samsung and SK Hynix make up nearly a third of the MSCI Asia ex-Japan Index, so suppliers further down the chain face the same spending risk.
- Nvidia CEO Says All of This Is Going to Pass After Tech Lost $1 Trillion in a Day
Nvidia CEO Jensen Huang told investors in Berlin on October 16 that “all of this is going to pass,” after the tech sector lost more than $1 trillion in value in a single session. The Nasdaq 100 fell 2.5%, and the Philadelphia semiconductor index dropped 3.8% for its eighth straight losing day, its longest such streak since 2008, while AMD and Intel each fell nearly 6%. Nvidia slid only 1.43% to $214.13, holding a $5.17 trillion market value and a 55.6% net margin that made it a safe harbor within the chip group. The article attributes the selloff to oil above $101 a barrel and the 10-year Treasury yield at 5.10%, forces that Huang's AI optimism cannot counter. Huang announced no orders, guidance or new customers, so his comments reflect the view of an executive who stands to gain most from continued AI spending.

- CoreWeave debt tumbles anew as Korean neocloud IPO tanks
CoreWeave's debt fell again on October 20 as investors reacted poorly to the public-market debut of Elice Group, a South Korean cloud company often called the South Korean equivalent of CoreWeave. Despite being almost 400 times oversubscribed and pricing at the top of its range, Elice's shares plunged over 32% in their KOSDAQ debut. The article says this is another sign that the neocloud business model might be broken. Elice locked in its IPO pricing on October 6, a day before macro anxiety and capex concerns.
- The bull case for CoreWeave as GPU demand surges
In the Loop host Ejaaz Ahamadeen makes the bull case for CoreWeave (CRWV), arguing that demand is pushing secondhand GPU prices higher. He cites comments from Amazon CEO Andy Jassy on demand for AI infrastructure and says AI capex differs from the dotcom era because buyers are willing to pay premiums. According to the host, secondhand GPU prices are at their highest ever, with older GPUs now worth twice their original price despite being 5 to 10 years old. He also argues CoreWeave's financing is not siloed, since customers such as Microsoft, Meta and Google can obtain attractive financing rates. He cites Elon Musk saying talks to buy compute from neoclouds have been the hardest ever, which the host attributes to providers having already pre-sold capacity at higher premiums.
- Where is Optimus? Key questions for Tesla earnings.
Hosts of The 8:30 preview Tesla's (TSLA) earnings report, where investors want updates on the Optimus robot, robotaxi expansion beyond Austin and SF, and capital expenditure. The key figures cited are revenue of $28.13 billion and EPS of 44 cents. Tesla announced capex of about $25 billion last quarter, and the hosts question whether it will go higher. The stock rose only about 1.7% this morning despite news of a possible SpaceX merger, and is still down 17% year to date after a strong rebound from its lows.
- SpaceX stock soars to its best day in two months while space peers climb out of a 26% hole
SpaceX (SPCX) opened with its biggest gain since its June debut and is on pace for its best day in two months. The rally follows third-quarter revenue and profit that beat Wall Street estimates, with the AI business now generating nearly half of sales. CEO Elon Musk said SpaceX and Tesla (TSLA) have each formed committees to study a merger. Through Tuesday, SpaceX was down just 2% in October, versus a drop of about 26% for the typical newer space stock. Chris Versace of Tematica Research said the planned $35B to $40B of fourth-quarter spending implies higher capex than the market expected, though it is backed by a $63B backlog, and up to 1.3 billion shares unlock on Thursday.
- Super Micro Soars 12% as Preliminary Revenue Blows Past Guidance on “Increased Demand for AI Platforms”
Super Micro (SMCI) jumped 12% after saying preliminary fiscal first-quarter revenue would be $18.5 billion to $19.5 billion, well above its earlier guidance of $14.5 billion to $15.5 billion. It also expects gross margin of 12.0% to 12.5%, above the 10.4% to 10.8% it had guided, which the article says matters more for earnings. Dell, HPE and Vertiv also gained, and Amkor rose after a $1.3 billion investment in South Korea. However, Super Micro burned nearly $7 billion of free cash flow last fiscal year, so its November 3 earnings call needs to show the bigger quarter turning into cash. The figures are preliminary and unaudited.
- Meta earnings preview: CapEx and Muse are in the spotlight
The 8:30 hosts preview Meta's (META) earnings report due tonight, highlighting capital spending and adoption of its Muse AI agent, including downloads and retention, as the two main items analysts will watch. Capex for the quarter is cited at about $41 billion. Consensus expectations are EPS of $3.56 and revenue of $63.3 billion. Options now imply a one-day move of about 6.6%, up from about 3.2% earlier. The stock surged after the Muse news but has since drifted lower along with the broader AI trade.
