The Philadelphia Semiconductor Index fell 11.41% last week and the Nasdaq Composite dropped 4.48%, as investors weighed debt-funded AI infrastructure spending amid expectations that rates could stay high for longer after September inflation exceeded forecasts. CoreWeave (CRWV) lost about a quarter of its market value during the week, Oracle shares fell 9.31%, and the cost of default protection on debt issued by AI-related companies rose. Meta (META) and Tesla (TSLA) report after the US close on Wednesday, SpaceX (SPCX) on Tuesday, and Netflix (NFLX) is also on the calendar, with investors focusing on investment spending and business performance. SpaceX recently agreed to acquire cellular spectrum licences from Grain Management for about $8 billion in cash.

- ASML is the Most Important Company in the AI Ecosystem , and It Just Delivered Record Results . Here Where the Stock Will Be in 2028
ASML reported record third-quarter results on Oct. 14, with revenue of €11.7 billion, up 56% year over year, a gross margin of 57.5%, and earnings per share up 136% to €12.95, and it raised its full-year guidance. The company expects €14.7 billion in revenue for the current quarter at the midpoint of its range. CEO Christophe Fouquet said customers don't expect supply to catch up with demand until at least 2028, while ASML aims to raise supply by 30% in both 2027 and 2028. The article argues that concerns about AI infrastructure spending may be overblown and, assuming 45% annual earnings growth, suggests the stock could rise about 72%, though it trades at 29 times forward earnings.

- Wall Street AI rally faces pressure ahead of Meta, Tesla and major chipmaker earnings reports
Wall Street's AI rally faces a test as investors await earnings from Meta, Tesla, chipmakers Lam Research and Texas Instruments, and SpaceX. Recent declines in AI, chip and hardware stocks such as Dell Technologies have raised doubts about whether the rally can continue. LSEG IBES data show S&P 500 earnings are expected to rise more than 30% in the third quarter, but investors want proof that heavy AI spending will pay off. Goldman Sachs expects five hyperscalers to lift combined capital spending to around $1.2 trillion next year. The S&P 500 posted its biggest weekly fall since June but remained only about 2% below its record high.
- TSMC Is Spending up to $64 Billion This Year. Here's Why That's Great News for Investors.
TSMC plans to spend $60 billion to $64 billion this year on factories and equipment, about a third of trailing-12-month revenue, which the article presents as a sign of coming growth. CFO Wendell Huang linked the spending to long-term customer demand, including agentic AI, and said spending from 2026 through 2028 should be significantly higher than in the previous three years. Third-quarter revenue reached a record $46.7 billion, up 41% year over year, with fourth-quarter guidance of $52.3 billion to $54.3 billion, and profit margin rose to 51.1% from 45.7%. The article notes geopolitical risks in Asia and says overseas plants such as Arizona cost more to run and may weigh on future margins. The stock trades at 19 times 2027 earnings estimates, with consensus calling for 28% earnings growth next year.
- 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
BCA Research's Peter Berezin sees AI as transformative but warns of a major market correction if productivity gains lag investment, with the core risk being financial and timing-related. The five largest hyperscalers are expected to spend over $1 trillion next year, while the industry may need about $10 trillion in annual revenue to justify the outlay. He says the equity bull market is mature rather than over, with a possible Nasdaq drawdown of around 50% in 2028, a bigger risk than 2027. He doubts China can offset a US slowdown and is neutral on equities and bonds near term, but expects to become more constructive on US duration, as real yields near 3% already offer attractive carry. He favors industrial metals over oil long term and remains bullish on gold.

- Tesla Stock vs. the S&P 500: Which Investment Wins Through 2030?
The article argues Tesla trades at roughly 203 times this year's expected earnings and 13 times expected sales, a valuation that looks very expensive given gross margin pressure and a slower-than-expected robotaxi rollout. The flying Roadster, slated for production in 2028, is unlikely to make a meaningful sales or earnings contribution before 2030. The author thinks a Tesla-SpaceX merger by the end of the decade, likely an all-stock deal, is more likely than not and would be a key factor in how Tesla stock performs against the S&P 500 through 2030.
- SpaceX surprises Wall Street with Oct. 20 earnings date — here's why
SpaceX (SPCX) will release earnings on Oct. 20 after the market close, a surprise since earnings dates are usually shared weeks in advance. Evercore ISI analyst Kutgun Maral says possible reasons include putting updated financials on record before new financing or getting ahead of major lock-up releases, though scheduling is also possible. Reuters reported SpaceX is seeking $40 billion in financing to buy advanced Nvidia AI chips, including about $10 billion in bank loans and $30 billion in investment-grade debt, with Apollo expected to lead. The lock-up schedule includes 1.30 billion shares two days after earnings, 329 million on 10/24, and a remaining 857 million tranche of the 180-day group.
- AEP Partners with Amazon and X-energy to Explore Advanced Nuclear Energy in Indiana
American Electric Power (AEP) has announced a joint development agreement with X-energy to evaluate the feasibility of a 960-megawatt advanced nuclear project at a former coal plant site in Sullivan County, Indiana. Amazon is supporting development through a funding agreement. If the project reaches a final investment decision and is built, Amazon intends to buy the power under a long-term contract covering the facility's costs and operations. The initial project would include 12 Xe-100 units of 80 MW each, and the companies say it could create jobs, expand the local tax base and strengthen the grid for more than 60 years. AEP says the agreements include the financial safeguards it considers essential for any nuclear project to move forward.
