South Korea's Kospi rose 6.6% on Wednesday after SK Hynix reported a sevenfold jump in September-quarter operating profit to 83.3 trillion won ($62.5 billion), beating forecasts by more than 7%, and announced 60 trillion won ($45 billion) in buybacks and dividends for the rest of the fiscal year. SK Hynix shares climbed 11% and Samsung Electronics jumped 9%, while Micron and SanDisk gained 4% in U.S. premarket trading. The company said conventional and high-bandwidth memory is sold out through 2029, with shortages expected to last at least until 2030. The rally follows a few days of AI stock recovery after weeks of pressure as investors questioned AI infrastructure spending.

- Samsung Stock Plunges Nearly 10 % as Kospi Triggers Circuit Breaker on China Chip Threat and Hot US Inflation
Samsung Electronics shares closed down 9.5% and SK Hynix fell 11.1% as the Kospi closed 7.57% lower at 5,554.22, its lowest close since April 7, triggering circuit breakers across South Korean markets. Investors cited competition from China's ChangXin Memory Technologies, which has developed a new DRAM design, US consumer prices rising 3.7% in September that raised expectations the Fed could raise rates again, and doubts about AI spending, with CoreWeave falling about 15% on Wall Street. Foreign investors net sold 3.62 trillion won ($2.68 billion) of Kospi shares, and the index has dropped about 20% over six trading days. Retail investors who bought leveraged ETFs tied to Samsung and SK Hynix were hit hardest. The won also weakened against the dollar.
- Samsung , SK hynix sell - off excessive as memory outlook stays strong : analysts
Samsung Electronics and SK hynix shares fell 23.9% and 31.5% over seven consecutive sessions starting Oct. 6, even as earnings forecasts rose on strong AI demand and tightening memory supply. Analysts said the sell-off reflected weak buying support and investor confidence rather than deteriorating fundamentals, calling the decline an excessive correction. SK Securities said next year's forecasts are being revised upward because the memory supply shortage may deepen and high-bandwidth memory prices may rise, while long-term supply agreements could improve earnings sustainability. Both stocks rebounded Friday as the KOSPI snapped its seven-session losing streak. SK hynix is scheduled to report third-quarter earnings on Oct. 28, followed by Samsung Electronics on Oct. 29.

- SK Hynix shares slide after chipmaker scraps Solidigm IPO plans
SK Hynix shares rebounded on Friday after falling as much as 3% earlier in the session, trading 3.2% higher following the company's decision to halt a review of a potential U.S. IPO for its subsidiary Solidigm. Solidigm said it made the decision after assessing capital market conditions and share price trends, and it will explore other funding options for a new U.S. chip fab. The company said an IPO could have funded expansion and provided more flexibility for shareholder returns, but market volatility led it to reassess whether the listing would benefit existing shareholders. South Korea's financial regulator said a U.S. listing could violate rules restricting dual listings and is examining minority shareholder protections. Broader markets were under pressure, with the Nasdaq Composite down 2.6% on Thursday, Nvidia down 4.4% and AMD down 8.1%, while CoreWeave fell 10% and was down 36% for the month and Australia's NextDC dropped nearly 40% on Wednesday after cutting its earnings forecast.
- SK Hynix Sinks 4% as Seoul Selloff Revives AI Spending Fears; SanDisk Drops 3%, Micron Eases
Memory chip stocks fell as a sharp selloff in Seoul, where South Korea's Kospi led Asian markets lower, revived concerns about how long the AI spending boom can last. SK Hynix (SKHY) was down 4% at $137.03, SanDisk (SNDK) fell 3% to $1,336.86, and Micron (MU) eased 2% to $886.64. The Roundhill Memory ETF (DRAM) dropped 3% to $46.75, a steeper decline than the 0.5% fall in the Invesco QQQ Trust (QQQ), pointing to a memory-led selloff. Separately, a union at Micron's Taoyuan operation in Taiwan plans a strike later this week over employee bonuses and profit sharing, and SK Hynix's upcoming earnings report could show whether AI memory demand holds up.

- Mortgage rates fell for the second straight week, but more borrowers still sought savings in riskier loans
The average 30-year fixed mortgage rate for conforming loans (up to $832,750) fell to 7.37% from 7.41%, and total mortgage applications rose 3.4% last week, according to the Mortgage Bankers Association. Refinance applications were still 61% lower than a year earlier, as about half of borrowers have rates below 4%, while purchase applications rose 4% but were 18% below last year. The ARM share of applications climbed to 11.3%, the highest in more than a year, and the 5/1 ARM rate eased to 6.41%; ARMs are seen as riskier because they adjust to market rates when the fixed term ends. Potential buyers remain worried about the broader economy, and some agents say buyers are waiting for the midterm election results.
- Google alters its cloud playbook, enlisting partners to sell more AI chips
Alphabet said Oracle will offer Google's TPUs, the first time customers can access them outside Google's infrastructure. Analysts expect Google Cloud revenue to jump about 90% from a year earlier, after 82% growth in the second quarter, when Google Cloud revenue was $25 billion versus $42 billion at AWS and $29 billion at Microsoft Azure. Anthropic agreed to use up to 1 million TPUs in a deal worth tens of billions of dollars, and CNBC confirmed OpenAI is also planning to buy TPUs. Broadcom detailed a $63 billion vehicle backed by Blackstone and three big banks to buy TPUs and lease them to Anthropic for five years. TD Cowen estimates a 20% operating margin on TPU sales, compared with about 35% for overall cloud margin last quarter.
- Searchlight Completes Airborne Magnetic Survey at Mari Lake Gold Project in Saskatchewan
Searchlight Resources (TSXV: SCLT) has completed a high-resolution airborne magnetic survey over the Mari Lake Gold Project in Saskatchewan, covering its expanded 57.0-square-kilometre claim package. The expanded property has approximately seven kilometres of exposure along the Kississing River Shear Zone, which hosts known gold-bearing structures. Preliminary interpretation highlights magnetic features near historical gold occurrences and a possible parallel structural zone that warrants further evaluation. The next step is to integrate the geophysical data with historical drilling, trenching and geological information to identify and prioritize exploration targets. The company cautions that historical results from 1945 to 1986, including 22 drill holes and 39 trenches, have not been independently verified, and drill intercepts are drill-indicated lengths rather than true widths.
- Barksdale Commences Updated PEA for San Javier Copper-Gold Project, Adding Gold for the First Time and Current Consensus Metal Pricing
Barksdale Resources (TSXV: BRO) has commenced an update to the Preliminary Economic Assessment (PEA) for its 100%-owned San Javier copper-gold project in Sonora, Mexico. The 2024 PEA assumed a copper-only heap leach operation at US$4.00/lb copper; the update adds metallurgical testing to assess gold and copper recovery and will replace that price deck with current consensus prices for both metals. In 2026, the company assayed 187 drill core reject samples from five holes drilled in 2007, with four of the five holes returning positive gold results, including 9.0 metres of 3.464 g/t Au in SJ07-64. The 250,000 to 400,000 ounces of gold cited in the 2024 PEA are conceptual, as no gold Mineral Resource has been defined. The update is expected to be completed in the fourth quarter of 2027.
- Google to preview crypto custody security system as AI threats grow
Google will unveil Google Multi-Party Compute (MPC), a service that splits a private key into fragments distributed across separate systems to help financial institutions custody and transfer cryptocurrencies and tokenized assets. The product is in private preview, with several design partners and major financial institutions testing it, and Alphabet has begun using it to secure its own assets on Ethereum and Solana; commercial availability is planned for early 2027, with pricing undisclosed. Chainalysis reported that compromised private keys accounted for 43.8% of cryptocurrency stolen in 2024, while DeFiLlama data showed $16.69 billion in cumulative hack and exploit losses as of June, roughly 40% linked to private-key compromises. Google says the complete private key is never stored in one place, reducing the risk of asset takeover even if a single machine is compromised.

BP Silver Corp. reported assay results from two more diamond drill holes, CO-0016 and CO-0019, at the Jalsuri North target in Phase 2 of its drilling program at the Cosuño Silver Project in Bolivia. CO-0019 intersected 10.0 m grading 183.62 g/t silver and 0.59 g/t gold (239.65 g/t silver equivalent), including 2.0 m at 506.50 g/t silver and 1.08 g/t gold starting at 3.0 m depth, and a 5.0 m interval from 4.0 to 9.0 m at 294.00 g/t silver and 0.81 g/t gold. Both holes were mineralized with zinc along their full lengths; CO-0019's lower zone graded 2.49% zinc equivalent over 100.0 m, while CO-0016 returned 96 m grading 1.37% zinc. The company said Jalsuri North may host a substantial polymetallic system, and further drilling is needed to determine the continuity of the mineralization.
