The PHLX Semiconductor Index (^SOX) is down about 3% after dipping to 11,000, a support level that has rescued chip stocks twice since September, so the bear-trap rebound only holds if that floor does. Since Oct. 6, all 60 stocks in Yahoo Finance's chip basket have fallen, erasing about $2.7 trillion in market value; Lam Research and Applied Materials are each down nearly 30%, AMD nearly 20%, and Nvidia 9%. Lam fell despite record revenue because it said supply limits would cap its outlook and China sales would be “meaningfully down” in December. The Nasdaq 100 is down about 6% over the same period. The article flags 10,450–10,550 as the zone to watch if 11,000 breaks, and 12,600–12,700 as the level bulls must reclaim, while semiconductor ETFs saw record flows over the past week.

- Nasdaq rises as SpaceX , Super Micro boost AI appetite
The Nasdaq rose at mid-morning as quarterly results from SpaceX and Super Micro Computer improved appetite for AI-linked stocks, with the Nasdaq Composite up 0.56% to 26,572.61 at 9:54 am ET while Netflix slipped. SpaceX rose 10.7% after Elon Musk called a SpaceX-Tesla merger 'a good idea' and the company posted its first profit as a public company, while Super Micro jumped 12% after forecasting revenue and profit margin above estimates. Chip stocks rebounded, with the Philadelphia SE Semiconductor index up 1.2% after 8 straight sessions of declines, but CoreWeave fell 2.4% and Netflix dropped 2.5% on a weaker-than-expected profit forecast. Markets largely expect the Federal Reserve to hold rates, even though last week's data showed price pressures spreading beyond energy and supporting the case for another hike, while Brent crude traded near $110 a barrel.
- Chips lead Nasdaq lower, oil tops 5-month high: AlphaCheck
Stocks were mixed on Tuesday as chip stocks gave up the previous session's rebound while oil prices climbed. Brent crude hovered near a 5-month high at $110 per barrel and WTI traded just below $100, following Houthi rebel attacks on Saudi Arabia amid the ongoing Middle East conflict. The tech sector fell, led by Nvidia (NVDA) and AMD (AMD), while memory makers Micron (MU) and SK Hynix (SKHY) also declined as Monday's rebound in the AI trade faded. Investors focused on earnings from GM, GE Aerospace and RTX released Tuesday, with SpaceX, Tesla and Meta also expected to report later in the week.

- Nvidia’s CEO Says “All of This Is Going to Pass” After Tech Lost $1 Trillion in a Day
On October 16, 2026, tech stocks lost more than $1 trillion in value in a single session as oil and Treasury yields rose. In Berlin, Nvidia CEO Jensen Huang said “all of this is going to pass” and that AI will benefit every industry, but he announced no new orders, guidance or customers. The Nasdaq 100 fell 2.5% to 29,187.55, and the Philadelphia semiconductor index dropped 3.8%, its eighth straight losing day and longest such streak since 2008. Nvidia slipped 1.43% to $214.13, a $5.17 trillion market value, holding up better than AMD, Intel, Micron and Broadcom. The article argues Huang’s comments do not address the real drivers of the selloff, namely WTI crude at $101.91 on October 14 and the 10-year Treasury yield at 5.10% on October 15, and calls the November 18 earnings report the key test.
- The Weekly Close: Chip Stocks Crater as Dow Holds Firm
Over the five days to 17 October 2026, the S&P 500 (SPY) fell 2.3% to 761.26 and the Nasdaq 100 (QQQ) dropped 5.64% to 707.87, its worst week since spring, while the Dow (DIA) rose 0.35% to 518.00. The gap was driven mainly by a sell-off of about a quarter in optical networking and AI-infrastructure names, including Lumentum (LITE), Ciena (CIEN), CoreWeave (CRWV), Hewlett Packard Enterprise (HPE) and Rocket Lab (RKLB), which fell between 25.03% and 25.59%. The top gainer, credit-data firm Fair Isaac (FICO), rose 14.21%, and most leaders came from outside technology. The article found no large disclosed insider sales among the week's biggest movers. Treasury yields eased modestly, with the 10-year at 5.1% and the 2-year at 4.77%, while WTI crude rose to $101.91 a barrel.
- We're downgrading this retail stock after a big comeback. Plus, AI names slide again
U.S. stocks fell Friday, with the Nasdaq down about 2.2%, the S&P 500 off 1.2% and the Dow down about 300 points, or 0.6%, as AI and infrastructure stocks came under pressure over rising capital costs and slowing revenue growth at Anthropic. The SOXX semiconductor ETF fell another 3% on the day and is down about 15% since its last positive day on October 5, while WTI crude climbed back to $100 per barrel. Defensive names such as Kimberly-Clark, Eli Lilly and Cardinal Health drew rotational buying, while CrowdStrike and Palo Alto Networks were among the portfolio's biggest decliners. The CNBC Investing Club downgraded TJX to a hold-equivalent 2 after shares rallied about 5% this week to $147, pushing the position to about 4.25%. Capital One and Meta are the only two portfolio companies scheduled to report next week.

Latest news
- Did Wall Street forget about Tesla's Cybercab?
Yahoo Finance's Brian Sozzi discusses Tesla (TSLA)'s Cybercab expansion and its relevance amid a possible merger with SpaceX (SPCX). Elon pointed to 2 million cumulative unsupervised robotaxi miles by quarter-end, Austin operating hours now run 6:00 a.m. to midnight, and more Cybercabs are expected in more cities in coming months. The Austin Cybercab fleet has grown by a factor of 10 since launch about a month ago. Tesla shares fell partly because the company cut capex by $5 billion, which Sozzi attributes to Optimus robot production bottlenecks rather than the Cybercab. He argues that with merger talks being explored, investors should start thinking of SpaceX and Tesla as one company.
- Crypto for Advisors: Stablecoins are ready for prime time
CoinDesk's Crypto for Advisors newsletter cites an EY-Parthenon 2026 Blockchain Payments Survey of 521 corporate and financial institution decision-makers. It found 18% of corporates have used stablecoins in production, double the 2025 share, while 15% report adopting tokenized deposits. Some 69% of financial institutions offer or plan to launch stablecoin services within two years, up from 30% in 2025. Cross-border business payments are the leading use case, and 45% of corporates and 53% of financial institutions favor using both stablecoins and tokenized deposits. Corporates strongly prefer blockchain payments integrated into existing banking interfaces (74%), and 63% would likely adopt them if offered by their current bank or payments provider.
- Is USA Rare Earth Stock a Once-in-a-Generation Reshoring Opportunity?
The article examines whether USA Rare Earth (USAR) can help the U.S. and its allies secure critical minerals, given China's dominance in rare-earth extraction and processing. China banned rare-earth exports in October 2025 in response to U.S. tariffs and chip restrictions; the ban was later temporarily lifted, though some Chinese companies have canceled U.S. exports, and China has also banned technology exports to USA Rare Earth and MP Materials. USAR shares are down roughly 15% in 2026 and about 74% from their lifetime high last October. Excluding the recently acquired Brazil-based Serra Verde, the company is essentially pre-revenue, though U.S. government supply agreements offer some pricing floor protection. With a market cap of roughly $4 billion and a target of about $1.8 billion in EBITDA for 2030, the author sees a worthwhile risk-reward profile for risk-tolerant investors, while stressing the stock is not low-risk.
- Nebius Declines 6% Despite Fresh Citi Financing; CoreWeave Drops 5%, Cloudflare Edges Higher
Nebius (NBIS) fell 6% to $162.03 despite a new senior secured credit facility from Citi, which matures in just under a year and is meant to fund data center development and GPU purchases while the company seeks longer-term asset-backed financing. CoreWeave (CRWV) dropped 5% to $58.86, while Cloudflare (NET) rose 2% to $313.35, with the article framing the selling as concentrated among neoclouds that rely on debt. A Barclays strategist noted that AI-spending credit stress has stayed largely confined to neocloud companies. Nebius has $37.5 billion in remaining performance obligations, $8.13 billion in capital spending, and three customers each accounting for a double-digit share of quarterly sales. The article says the Citi line adds to leverage concerns, making the timing and terms of the next financing a key test.
- How agentic AI shopping changes consumer staples: P&G CFO
P&G reported strong first-quarter earnings and reiterated its full-year revenue forecast. In an interview with Yahoo Finance, CFO Andre Schulten said that people using its products remains the core of the business, but the consumer's path to purchase is changing as AI agents buy on people's behalf, so P&G is proactively working out how agent-to-agent marketing works and how to distribute brand information. He said the company is also using decades of collected data and simpler algorithms to speed up molecule discovery, automate data extraction and analysis, and make forecasting more efficient. On marketing, he said algorithms weigh credibility, so P&G plans to publish and make accessible its scientific publications, independent studies and consumer reviews, an approach he believes gives big brands an advantage.
- SpaceX Just Became an AI Company. The Numbers Prove It.
SpaceX reported third-quarter revenue up 161% year over year to $14.6 billion and net income of $4.4 billion, making it profitable. Its AI segment, now called 'super intelligence (SI),' generated $7.6 billion in revenue, up 830% year over year and 195% sequentially, making it just over half of sales and the largest revenue source. Connectivity remains the most profitable segment with $2.4 billion in operating income, versus $431 million for SI, which lost $1.26 billion last quarter. SI accounted for $16.4 billion of the company's $19.6 billion in Q3 capital expenditures, but the results should ease concerns that it is a money pit, as cloud agreements with Alphabet and Anthropic and $608 million of Cursor revenue since its August acquisition show the investments are paying off. The author notes the stock remains richly valued.
