The Philadelphia semiconductor index fell 3.8% on October 16, 2026, its eighth straight losing session and longest run since 2008. The SOXX fund dropped 4.14% to $493.39 but is still up 64.12% for 2026. The article argues this selloff differs from 2008, driven by high oil (West Texas crude at $101.91 a barrel on October 14), a 5.10% 10-year Treasury yield, and doubts about returns on AI spending. Bank of America analyst Sebastian Raedler says hyperscaler capital spending forecasts have tripled to $1 trillion from $330 billion in early 2025, and warns past capital cycles often ended in disappointment. AMD fell 18.58% from its October 6 close to $528.75, and the article says it swings more than SOXX because its upside depends on Helios shipping on time.

- Nvidia wins CPU business from Modal, previously exclusive to AMD and Intel
Modal, a San Francisco-based AI cloud startup that previously ran its AI agent workloads only on Intel and AMD processors, will begin using Nvidia's new Vera CPU. Early tests showed the Nvidia chip doubled work capacity for AI agents, and Modal plans to run it alongside Intel and AMD chips, assigning each task to the most efficient hardware, though integration requires substantial software changes. Modal recently raised $750 million in a round led by Accel at a $15.75 billion valuation and expects $1 billion in sales over the next year, with usage tripled and revenue up more than 15 times year-over-year. Nvidia projects at least $20 billion in Vera chip revenue this fiscal year in a market it estimates at about $200 billion, and says OpenAI, Anthropic, Oracle and Perplexity also plan to use the chips.

- Tech Sell-Off: 2 Growth Stocks Investors Might Regret Not Buying on the Dip
Many AI-leading stocks are pulling back after three years of strong gains, as investors worry about rising data-center funding costs and weaker-than-expected future demand. The iShares Semiconductor ETF is down more than 20% from its June peak and is in bear territory, weighing on the Nasdaq-100 and S&P 500. The author highlights two non-semiconductor AI stocks: Datadog (DDOG), whose revenue growth accelerated to 36% in Q2 and whose 2026 revenue forecast was raised by $140 million to $4.46 billion, though its P/S of 24.3 is well above its three-year average of 17.7. Palo Alto Networks (PANW) reported next-generation security ARR of $9 billion, up 63%, and targets $20 billion by fiscal 2030.
- AI trade reversal pierces Asia star picks - and - shovels stocks
A selloff in US tech stocks is raising concerns that rising financing costs could curb AI infrastructure spending, threatening earnings across Asia's chip supply chain. Oil surged to $110 a barrel, stoking inflation worries, while an eight-session rout in US semiconductor shares, the longest since 2008, cut roughly 16% from the sector benchmark. A Goldman Sachs basket of regional AI hardware stocks fell 11% last week. Nan Ya Plastics dropped 12% from a record high, Unimicron fell 14% and Samsung Electro-Mechanics plunged 23%. CoreWeave's bonds sank to levels signaling distress, and Gartner warned more than $3.5 trillion of AI infrastructure spending could be impaired by 2030. TSMC, Samsung and SK Hynix make up nearly a third of the MSCI Asia ex-Japan Index, so suppliers further down the chain face the same spending risk.

- Saudi Arabia postpones big investor conference to 2027 as Iran-backed Houthis escalate attacks on kingdom
Saudi Arabia has postponed its major annual investor conference until 2027 as Iran-backed Houthi militants escalate missile and drone attacks on the kingdom. The Future Investment Initiative had been scheduled for Riyadh from October 26 to 29. The decision follows a Houthi attack on King Khalid International Airport in Riyadh on October 10, which left at least 12 people dead and more than 300 injured. Organizers said in an email that new dates will be announced soon.
- Russia fires mysterious weapon at Kyiv, shockwaves spread; President Putin appears in rare image, drawing global attention
On the night of 18 Oct, Russia launched a coordinated strike on multiple Ukrainian targets using ballistic missiles, cruise missiles and Geran UAVs, focused on Kyiv. According to TST, around 10 ballistic missiles of the Iskander-M, S-400 or KN-23 types may have been used in the first wave; an above-ground metro station on Kyiv's left bank was reported damaged, disrupting rail and metro services, and videos of blue flashes led observers to suspect a new weapon. In western Ukraine, a 330 kV transformer station near Kovel may have been targeted. Meanwhile, Putin, who rarely appears in military uniform, visited a command post and stressed establishing a “security zone” along the border; blogger Yuri Podolyaka argued Moscow no longer treats these areas as bargaining chips. Front-line correspondent Alexander Kots said the part of Donetsk still controlled by Ukraine is just over 2,700 km².
- Semiconductor Sell-Off: 5 Stocks to Buy on the Dip
The article attributes the semiconductor selloff to investor doubts about the durability of AI infrastructure spending, even as cloud companies report strong demand for AI chips. It highlights five stocks: Nvidia (forward P/E just above 13.5 on fiscal 2028 estimates), Broadcom (custom AI chips, with that revenue expected to quadruple to $230 billion over two years; forward P/E of 11), AMD (riding inference and agentic AI demand), Cerebras Systems (high risk-reward; the company claims 30 times the inference speed of GPUs) and TSMC (forward P/E of 18 on 2027 estimates).
- Tom Lee’s Bitmine Adds $30 Million in Ethereum as Buying Nears Its Finish Line
Bitmine bought another 12,535 ETH (about $30 million), lifting its holdings to 6,041,481 ETH, or 4.9% of supply and 99% of its 5% target. Chairman Tom Lee blamed the crypto selloff on a broad risk-off shift, including AI funding and safety worries, U.S.-Iran tensions, midterm jitters and rising bond yields, and called the dip a historically attractive risk-reward entry. Total holdings reached $15.1 billion as of Oct. 18, including 215 Bitcoin, $582 million in cash and marketable securities, and other investments. About 84% of its ETH (5,067,309 tokens) is staked via its MAVAN platform, with projected annualized revenue of roughly $309 million. The position is currently underwater on paper because much of it was bought at higher prices.
- Opinion: The Most Important Number in Taiwan Semiconductor's Earnings Report Was 68%
The author argues the most important figure in TSMC's Q3 report is 68%, the share of revenue from high-performance computing (HPC), which grew 22% from the prior quarter. Revenue reached $46.72 billion, up 41.2% year over year, net income rose 68.7%, and gross margin hit 66.4%. Processes at 7nm and below made up 79% of wafer revenue, with 3nm at 33% and 2nm at 8%. TSMC guided Q4 revenue to $52.3–54.3 billion and expects roughly 44% full-year growth in U.S. dollars. The author remains bullish, saying ongoing demand for advanced AI chips should keep profits rising.
- Why Meta's Q3 earnings could be a little hard to interpret
Meta is reporting its third-quarter earnings after the market closes Wednesday, and Yahoo Finance's Brian Sozzi says the report will be hard to interpret. Recent good news on Meta's AI products, including new models and an AI agent, may not appear directly in the results but will likely be discussed on the earnings call. The key uncertainty is how investors will react if Meta raises its capex outlook again: it could be seen as fueling those products, or as overspending on offerings not yet reflected in financials. Sozzi expects the market to give Meta the benefit of the doubt on higher capex, as long as the increase does not shock investors.
