• Nasdaq 100 ( Week of Oct . 17 , 2026 ) - 博客

  The Nasdaq 100 posted its worst weekly performance in 18 months, falling 4.5% in the week ending October 16, 2026. Tech and AI-linked stocks slid over doubts about when debt-heavy AI infrastructure firms will turn profitable, along with high oil prices and hot inflation data. Both the Nasdaq Composite and Nasdaq 100 dropped below their 50-day moving averages, and the VIX rose above 20 for the first time since July. Nebius Group (NBIS) and CoreWeave (CRWV) fell about 12% on Friday alone, and the Philadelphia Semiconductor Index posted its eighth consecutive daily loss, its longest losing streak since 2008. Meanwhile, defensive names such as T-Mobile US, Costco and Walmart posted moderate gains, and analysts favor mega-caps Nvidia, Microsoft and Meta.

• AI Investment boom raises cross - asset risks as capex cycle matures , says BCA research strategist

  Peter Berezin, Chief Global Macro Strategist at BCA Research, says AI can remain transformative but could trigger a significant market correction if productivity gains fail to keep pace with investment. He argues the core risk is financial and about timing, as returns may arrive too slowly to justify current capital spending, with the five largest hyperscalers expected to spend more than $1 trillion next year. Berezin believes the equity bull market is mature rather than over, expecting consolidation and volatility before a more material downturn; a US recession in 2027 looks unlikely, but 2028 poses a bigger risk, potentially with a Nasdaq drawdown of around 50%. He sees China unlikely to offset a US slowdown and remains neutral on equities and bonds in the near term.

• AI Investment boom raises cross - asset risks as capex cycle matures , says BCA research strategist

  Peter Berezin of BCA Research says AI can remain transformative but could trigger a significant market correction if productivity gains fail to keep pace with investment. The core risk is financial and about timing, as returns from AI adoption may arrive too slowly to justify current capex. The five largest hyperscalers are expected to spend over $1 trillion next year, and the broader AI industry could need roughly $10 trillion in annual revenue to monetize projected investment, based on his assumptions. He views the equity bull market as mature rather than over, expecting consolidation before a bigger downturn, with 2028 posing a greater risk and a possible Nasdaq drawdown of around 50%. He remains neutral on equities and bonds near term, while real yields near 3% already offer attractive carry.

• Nasdaq 100 Sees Best Day In Nearly A Month As AI Rout Cools — AMZN, BE, CRWV, AAPL, PLTR In Focus

  The Nasdaq 100 rose 1.2% on Monday, its best day in nearly a month, as investors returned to AI stocks after a week-long sell-off. The S&P 500 gained 0.4% and the Dow Jones slipped 0.1%, while the VanEck Semiconductor ETF (SMH) gained just over 2%. The Nasdaq had fallen 4.5% the previous week amid worries over the AI trade, including Anthropic's reported Q3 sales of $16.8 billion (up from $11.6 billion in Q2), bond investors pulling back from CoreWeave, and a Gartner forecast that 80% of the neocloud market would cease to exist. Amazon shares rose nearly 5% after Morgan Stanley reaffirmed its 'Overweight' rating. Investors are now looking to Meta and Tesla earnings this week.

• Nvidia CEO Says All of This Is Going to Pass After Tech Lost $1 Trillion in a Day

  Nvidia CEO Jensen Huang, speaking in Berlin on October 16, 2026, said “all of this is going to pass” after a selloff that wiped more than $1 trillion from tech stocks in one day. The Nasdaq 100 fell 2.5% to 29,187.55, while the Philadelphia semiconductor index dropped 3.8% for its eighth straight losing day, its longest streak since 2008, as oil hit a five-month high. Nvidia slipped 1.43% to $214.13, while AMD, Intel, Micron and Broadcom fell between 4.52% and 5.95%. The article argues the pressure came mainly from oil and Treasury yields, with the 10-year at 5.10%, rather than from AI itself, and notes that Huang announced no new orders or guidance. Investors will look to Nvidia's November 18 earnings, where management guided to fiscal third-quarter revenue of $108.0 billion, plus or minus 2%.

• Tech stocks tumble Friday , AI shares lead the way

  U.S. stocks ended Friday broadly lower as a sharp spike in oil prices and a plunge in AI-linked technology shares pressured the market. The S&P 500 fell 84.62 points (1.09%) to 7,659.44, the Dow Jones Industrial Average dropped 175.28 points (0.34%) to 52,002.41, and the Nasdaq Composite lost 572.99 points (2.14%) to 26,140.03. Market participants pointed to rising energy costs as a key driver of the risk-off mood, stoking concerns about inflation and corporate margins. The U.S. dollar weakened against most major currencies, with the yen the main exception, while world equities mostly gained, though Indonesia's IDX Composite plunged 11.57%. Japan's Nikkei 225 rose 1.39% to 65,324.29, Germany's DAX gained 0.95% to 25,622.61, and London's FTSE 100 added 0.38%.

• SpaceX Just Crushed Wall Street's Q3 Targets -- but a Potential Tesla Merger Is Even Bigger News

  SpaceX reported third-quarter adjusted EPS of $0.45 on sales of $14.58 billion, far above analyst averages of $0.13 and $12.72 billion. Revenue rose 161% year over year and net income swung to $4.4 billion from a $1.1 billion loss a year earlier; Starlink sales grew 69% to $5.25 billion, while the superintelligence segment rose about 830% to $7.56 billion. The company guided first-quarter 2027 sales to $33–37 billion, and Musk said he expects annual recurring revenue of $500 billion–$1 trillion by the end of next year. On the call, Musk said special committees had been formed to explore a merger with Tesla, that he could not take part due to conflicts, and that merging was a good idea, though shareholder approval equal to 50% of total shares would be a significant hurdle.

• Chip stocks break a bear trap after a $2.6 trillion rout — here are the levels bulls need to hold

  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.

• A New Mexico Judge Just Hit Meta With a $25 Billion Penalty

  On October 21, 2026, a New Mexico judge ordered Meta to pay the state $25 billion over misleading Facebook users about privacy in the Cambridge Analytica case, far above the FTC's $5 billion fine in 2019. Jurors found 26 of 29 statements misleading, and counting each statement per user or resident who saw it produced more than 43 million violations, with state law allowing up to $5,000 each; all the money goes to New Mexico schools. The judge said the conduct went to the heart of Facebook's core business and found that senior leaders, including Zuckerberg and Sandberg, misrepresented its privacy practices. Meta is appealing, has paid nothing, and interest keeps accruing, while the penalty equals about 2.5 times its $9.86 billion third-quarter net income.

• Elon Musk says Tesla's Optimus robot needs to learn like a toddler

  Elon Musk said on Tesla’s earnings call that Optimus humanoid robots must learn through self-play at scale, since Tesla lacks the vast car fleet that supplies training data, likening this to how a toddler learns to navigate the world by playing. Tesla cut its 2026 capex outlook to about $20 billion from $25 billion as it prioritizes usable humanoids. Optimus V3 production began at Fremont in the summer after Model S and Model X output ended there, with about 1,000 Gen 3 units already operating on the production floor. William Blair analyst Jed Dorsheimer said Musk pushed the timeline for a 1 million-unit weekly run-rate to over a year, with first applications in dangerous industrial settings by the end of 2027.

• Meta's new stock sale sends one signal: AI demand isn't slowing down

  Brian Sozzi of Yahoo Finance sees Meta's new non-voting share class as a positive signal. CFO Susan Li said the class can be used for capital raising, employee pay and acquisitions while preserving the voting power of existing Class A and B shareholders. Sozzi expects Zuckerberg to remain CEO for at least 15 more years, and says raising capital through stock may be cheaper than borrowing, since debt costs could rise for borrowers such as CoreWeave. He also reads the sale as a sign that AI demand is not slowing, pointing to better ad placement and monetization that helped the quarter's results.

• Elon Musk: SpaceX Revenue Could Hit “Somewhere Between $500 Billion and a Trillion” by 2027

  On the earnings call, Elon Musk said SpaceX’s annual recurring revenue could reach between $500 billion and a trillion by the end of 2027, a goal that requires building compute faster than almost any company has tried. SpaceX posted its first quarterly profit of $4.4 billion in the latest quarter, versus a $1.1 billion loss a year earlier, with revenue up more than 160% to $14.6 billion; capex of $19.6 billion could reach $40 billion next quarter. Management says new compute installations pay back in under a year if prices hold, but the target of 13 GW by end-2027, up from 1.7 GW, depends on power, cooling, and NVIDIA’s Vera Rubin systems arriving on time. Shares rose 7.79% to $159.31, and a Tesla combination would need approval from 50% of Tesla’s outstanding shares, a hard bar given many holders never vote.
