  • Wall Street muscles higher despite more swings for AI stocks - Boston News , Weather , Sports

    U.S. stocks rose Thursday as companies reported bigger-than-expected profits, pulling closer to their records even as AI stocks kept swinging sharply. The S&P 500 gained 0.3%, the Dow Jones Industrial Average jumped 556 points (1.1%) and the Nasdaq composite added 0.1%; Marsh & McLennan rose 4.6%, Kimberly-Clark climbed 4.7% and Bank of New York Mellon gained 3.2% after reporting stronger-than-expected profits. Earlier, a sell-off in AI stocks had sent South Korea's Kospi down 7.6% and Japan's Nikkei 225 down 4.9%. Nvidia fell 1.8% and was the heaviest weight on the S&P 500, while Taiwan Semiconductor Manufacturing Co. finished down 1.8%; CoreWeave, by contrast, closed 5.9% higher after falling 15.5% a day earlier. The 10-year Treasury yield sank to 5.09% from 5.19% as investors sought safer government bonds, even though a report showed inflation had worsened more than economists expected.

  • AI stocks just lost $5 trillion — but history says the stock market's sweetest stretch starts now

    According to Yahoo Finance, the biggest AI and chip stocks have shed about $5 trillion in market value since Oct. 6, while 625 other large US stocks added about $1.3 trillion; Nvidia and Alphabet each lost roughly $835 billion. Jeff Hirsch of the Stock Trader's Almanac says the damage is not as bad as the headlines and that he bought some shares, pointing to the 'sweet spot' from the fourth quarter of a midterm year through June, when the S&P 500 has risen 19 times out of 19 since 1950, with a median gain of about 15%. Chip stocks have risen 8 out of 8 times since 1994, with a median gain of about 22%, though in some cycles they fell another 11% or so first. BofA's Michael Hartnett, however, says the market is 'risk-off until global rate hike ends,' citing 42 central bank rate hikes worldwide over the past six months.

  • Santoli: We are nearing a now-or-never moment for the AI trade to rebound

    The S&P 500 has moved sideways for months, while former AI leaders (tracked by the iShares AI Innovation ETF) fell 35 percentage points relative to the equal-weight S&P 500, recovered half, then gave back most of the bounce. Higher bond yields and oil above $100 a barrel have pressured cyclical sectors, and tighter debt markets are raising hurdle rates for marginal AI data-center borrowers. Goldman Sachs cited trader exhaustion, noting the momentum-factor basket moved at least 5% in a day 30 times in 2026. John Kolovos of Macro Risk Advisors says sentiment is nearing a “fat pitch” for a tactical rebound, but the macro backdrop must cooperate, and hedge funds have sharply cut leverage and tech exposure. Citadel Securities data show retail investors heavily buying dips, yet past market bottoms came when retail traders were net sellers, so any rebound may prove limited in strength and durability.

  • Tumbling AI stocks overwhelm markets worldwide as oil prices jump

    The S&P 500 fell 1.2% and the Nasdaq Composite tumbled 2.6% on Thursday, the index's worst day since July, as AI stocks slid on worries about the cost of borrowing to build data centers and high valuations. Lam Research dropped 11.6% despite slightly stronger-than-expected profit and revenue, while Meta fell 7.9%, Nvidia 4.3% and CoreWeave 11%. Asian markets also fell, with South Korea's Kospi down 3.5%, Hong Kong's Hang Seng down 3% and Japan's Nikkei 225 down 2.7%. Brent crude rose 3.7% to $112.80 a barrel, touching its highest level since May, while the 10-year Treasury yield fell to 4.96% from 5.13% as investors sought safer assets. Most U.S. stocks still rose, and the Dow Jones edged up less than 0.1%.

  • Investors Fined for Manipulating Kido Shares

    Three investors were fined a total of 4.5 billion dong for manipulating shares of Kido (KDC) and for lending accounts used in the manipulation. Under the State Securities Commission's decision dated 28/10/2026, Thang Phú Minh, Lâm Thúy Hằng and Dương Thái Phương Thảo were each fined 1.5 billion dong for using 61 accounts to trade KDC shares repeatedly between 2/5/2024 and 6/1/2025, creating artificial supply and demand. The three are also banned for two years from trading securities and from holding positions at securities firms and fund managers in Vietnam, effective 2/11/2026. Separately, 17 individuals who lent their accounts were suspended from trading for nine months and face the same two-year bans, though no illegal gains were identified for them.

  • 2 Space Stocks Down More Than 50% That Could Be the Best Buys of Q4

    AST SpaceMobile (ASTS) is down roughly 69% from its May 2026 peak, while Rocket Lab (RKLB) has fallen more than 60% from its record high, as investors reassessed timelines and competition. Bank of America expects AST to begin initial intermittent cellular coverage in the U.S., Canada, Japan, the U.K. and Saudi Arabia before the end of 2026, backed by partnerships with more than 60 mobile operators serving over 3 billion subscribers. AST launched 13 satellites in August but still faces execution, competition and funding risks. Rocket Lab reported record Q2 2026 revenue of about $234 million, up 62% year over year, and a record backlog of $2.4 billion, up 137%, while it agreed to acquire Iridium Communications and delayed its Neutron rocket debut to 2027. Analysts' target prices imply potential upside of 10% to 157%, and the stock trades at about 41 times sales.

  • Copilot AI Predicts Solana Could Hit $2,500 if This Landmark Event Happens

    Microsoft's Copilot AI forecasts SOL could reach $1,000–$2,000 by January 1, 2027, with a stretch target toward $2,500 or more if a full crypto bull market is fueled by a major consortium adopting Solana for consumer apps and real-time payments. The article stresses this outlook is extreme and far beyond mainstream forecasts, with SOL trading near $95 as of November 1, 2026. On technicals, SOL is consolidating in the $115–$125 range, with resistance at $130–$150 and a prior all-time high near $296, and nearer supports at $110–$115 and $100–$105. The author argues that a normal bull market supports further upside, but only an extraordinary surge in real-world adoption could justify gains of several thousand percent to reach the $1,000–$2,500 targets. Five potential catalysts are cited: traditional financial restrictions, geopolitical instability, interest rate cuts, Bitcoin's next rally and institutional investment.

  • Apple's new earnings era begins at a critical time for Big Tech

  • Why Micron Stock Looks Cheap After a Record Year

    Micron, which makes memory chips for PCs and AI servers, posted a record fiscal 2026 with revenue of $133 billion and adjusted earnings of $75.52 per share, up from $8.29 a year earlier. Yet the stock closed on Oct. 28 about 13% below its earnings-day close, trading at a forward P/E of about 5.5 versus about 19 for the S&P 500. Micron has signed 26 long-term strategic customer agreements covering over 35% of expected revenue through 2030, backed by $32 billion in customer financial commitments. Adjusted free cash flow reached $62 billion for the full year, while capital spending of about $27 billion in fiscal 2026 and about $25 billion planned for the first half of fiscal 2027 will fund new supply. The article says DRAM prices and days of inventory are the two metrics to watch: if prices keep climbing and inventory days fall as management expects, the stock could keep surging next year; if inventory keeps rising while prices stall, that signals excess supply.
