- Live updates: Bitcoin tags $83,000 and slips back as chip stocks lead a rebound
Bitcoin climbed from an overnight low near $80,700 to just above $83,000 early Monday, then slipped back to about $82,400 as sellers stepped in, and was up 0.3% over 24 hours. The bounce followed tech stocks, with Nasdaq 100 futures up 1.1%, snapping a weeklong 5.5% selloff, and an ETF tracking chipmakers jumping 3%. WTI crude recovered to $98.55 after touching $96.72, as the U.S. warned citizens across 12 Middle East locations of possible flight cancellations and airspace closures, raising fears of fresh strikes on Iran and disruption at the Strait of Hormuz. In Europe, the Stoxx 600 fell 0.8% after protests in France. Bitcoin would need to move through $84,000, its ceiling on October 13 and 14, to signal that the tech rebound is lifting it too.
- South Korea to meet crypto exchanges amid calls for tax delay
South Korean finance officials are reportedly set to meet major crypto exchanges, including Upbit, Bithumb, Coinone, DigitalX and Gopax, on Tuesday, days after a lawmaker introduced a bill that could delay the crypto tax by two years. The tax has already been postponed three times and is currently scheduled to start in January 2027. An exchange official said unresolved transaction standards and limited time to prepare infrastructure support a delay. Democratic Party lawmaker Park Min-gyu's bill would push the start date to January 1 of the second year after Korea begins sharing data under the OECD's Crypto-Asset Reporting Framework; with the first data exchange expected in 2027, taxation would begin in 2029.
- Seoul stocks extend losses amid AI concerns
Seoul shares fell sharply late Tuesday morning as a sell-off in major chip stocks, driven by concerns over AI-related investments, deepened losses. The KOSPI dropped 136.06 points, or 2.36%, to 5,631.95 at 11:20 a.m., after touching an intraday low of 5,493.24. Samsung Electronics fell 1.03% and SK hynix dropped 2.74%, while Samsung Electro-Mechanics rose 2.48%. The won traded at 1,327.6 per U.S. dollar. In the U.S., tech shares rebounded from their steepest weekly drop since June, with the Nasdaq Composite gaining 1.11%, but investors remain cautious ahead of earnings from Tesla and Meta Platforms and the Nov. 3 U.S. midterm elections.
- South Korea , Japan shares fall as Asian stocks decline in break from US chip rally
The MSCI Asia Pacific Index fell 0.6%, with eight of its 11 subgroups down, breaking from a chip-led Wall Street rally. South Korea's Kospi dropped more than 2% and SK Hynix hit its lowest close since April, while data centre firm Elice plunged as much as 32% in its Seoul debut. Japan's Nikkei 225 futures fell 0.8% and Topix dropped 0.9%, while the Philadelphia Semiconductor Index had gained 1.6% on Monday, snapping an eight-day losing streak. The 10-year US Treasury yield was at 5.14% after rising seven basis points on Monday. China's central bank said its overnight reverse repo rate will replace the seven-day rate as the policy benchmark, while gold slipped 0.2% to about US$4,130 an ounce.
- Micron Stock Rises 4 % as Memory Chipmakers Recover After 15 % Weekly Plunge Tied to China Competition Fears
Micron shares rose more than 4% to $916.29 by 10:27 a.m. ET on Monday, leading a rebound in memory chip stocks after a 14.6% drop last week. The sell-off followed China's ChangXin Memory Technologies (CXMT) unveiling an advanced DRAM design, which raised fears of expanded Chinese supply and lower prices. Samsung Electronics and SK Hynix also fell sharply, triggering a circuit breaker on the Korean market. Some analysts argue the threat is overstated in the near term, given leading makers' advantages in high-bandwidth memory used for AI. Broader selling was also driven by hotter-than-expected U.S. inflation data, and investors will watch Meta Platforms' results this week for AI spending signals.
- Prediction: This Will Be Micron's Stock Price By the End of 2027
Micron's shares have risen 333% over the past 12 months as AI data center clients buy its memory chips, with fourth-quarter revenue up 379% year over year to $54.23 billion and net income up more than 10-fold to $37.7 billion. The company has authorized $35.7 billion in share repurchases, and its forward P/E of 7 compares with an S&P 500 average of 19. The author links the low valuation to a sell-off in South Korea, where the KOSPI has fallen over 40% from its June peak, erasing more than $2 trillion, on fears of rising bond yields and growing competition from China's CXMT. Some South Korean experts forecast a memory chip supply glut by 2029, which the author says could bring years of stagnant performance similar to the period after the dot-com bubble. The author concludes investors shouldn't expect the stock to exceed its current price of $879 by the end of 2027.

- Inflation Just Hit 3.7%. Here's Why Walmart and Costco Could Be the Biggest Winners.
The US Consumer Price Index rose 3.7% over the 12 months ending in September, up from 3.4% in August, according to the Bureau of Labor Statistics. Gasoline was the biggest driver, up 9.1% for the month and 34.2% over the year, while core inflation was 2.6%. Food away from home rose 3.5% over the year, faster than the 1.8% increase in food bought to cook at home. The article argues Walmart (WMT) and Costco (COST) benefit from thin markups and value pricing, with Costco's fiscal fourth-quarter sales up 11.2% to $93.9 billion and Walmart's revenue up 5.9% to $187.9 billion. Walmart trades above its own five-year median on forward earnings, while Costco is near its historical average, and the author says neither is a bargain.
- AI chip stocks bounce back as hyperscaler earnings loom, META equity raise in focus
AI chip stocks rebounded on October 19, with the Nasdaq up 1.3%, NVIDIA gaining 1.38% and Meta Platforms slipping 0.55%. Evercore ISI sees the recent pullback as coming ahead of a strong hyperscaler earnings season, and NVIDIA expects top five hyperscaler capex to reach nearly $800 billion in 2026. Meta guided 2026 capex to $130 billion to $145 billion, while second-quarter free cash flow fell to $784 million from $8.55 billion a year earlier. Analysts expect a Meta stock sale, and according to the article, the market is reportedly comfortable with about $30 billion, though Meta has not announced an offering. The article notes H100 pricing has held up, NVIDIA says it has supply for about 70% of demand, and GPU-backed loans are seen as the go-to option over unsecured debt at 15%.
- Mt. Gox Pushes Repayment Deadline to 2027 With $2.8B in Bitcoin Still to Distribute
Mt. Gox's rehabilitation trustee, Nobuaki Kobayashi, has pushed the repayment deadline back one year to October 31, 2027, with a Tokyo court's approval, because many creditors have not completed the required procedures or ran into problems. It is the fourth one-year extension, and about 19,500 creditors had received funds by the October 2026 deadline. Arkham data shows wallets linked to Mt. Gox still hold about 34,388 BTC, worth roughly $2.8 billion, with no transfers since June apart from a move of 10,422.65 BTC, mostly to a new wallet. Observers now see the remaining coins as a smaller risk, with one analyst calling the repayments 'more of a recurring headline than a real source of downside pressure.'
