For the week, the S&P 500 lost about 2% and the Nasdaq fell more than 4%, its worst week since June, while the Dow gained 0.7%. Investors now turn to earnings from Meta, Tesla, SpaceX, Netflix and others, plus fresh economic data, as the AI trade faces a key test.
- US Market Outlook : Indices knocked down - The HinduBusinessLine
The Dow Jones held up last week, while the S&P 500 fell 1.95% and the NASDAQ Composite tumbled about 4.5%. According to the article's technical analysis, the Dow (52,007.21) is near 52,500 resistance and risks falling back, while the S&P 500 (7,659.44) has broken support at 7,730 and could drop to 7,500-7,450 if it breaks below 7,600. The NASDAQ Composite (26,140.03) may fall to 25,500-25,000 unless it rises back above 27,000. The dollar index (101.78) failed to hold above 102.50, and the US 10-year Treasury yield fell to 5.08% after breaking below 5.2% support.

Over the five days to 17 October 2026, the S&P 500 (SPY) fell 2.3% to 761.26 and the Nasdaq 100 (QQQ) dropped 5.64% to 707.87, its worst week since spring, while the Dow (DIA) rose 0.35% to 518.00. The gap was driven mainly by a sell-off of about a quarter in optical networking and AI-infrastructure names, including Lumentum (LITE), Ciena (CIEN), CoreWeave (CRWV), Hewlett Packard Enterprise (HPE) and Rocket Lab (RKLB), which fell between 25.03% and 25.59%. The top gainer, credit-data firm Fair Isaac (FICO), rose 14.21%, and most leaders came from outside technology. The article found no large disclosed insider sales among the week's biggest movers. Treasury yields eased modestly, with the 10-year at 5.1% and the 2-year at 4.77%, while WTI crude rose to $101.91 a barrel.

- Is Nvidia Stock Really Trading for Just 8 Times 2030 Earnings?
Nvidia is the market's most valuable company, with a market cap above $5 trillion. It trades at 27 times adjusted trailing earnings, but only about 8 times analysts' estimate for fiscal 2030 earnings, a figure the author stresses is a moving target. Revenue growth accelerated from 56% in Q2 FY 2026 to 106% in Q2 FY 2027, though guidance points to a slight slowdown in the current quarter. The stock trades at 13 times next year's earnings, and the board recently authorized a record $150 billion in share repurchases. The author also acknowledges risks such as slower growth or contracting net margins.
- US Orders Civilian Agencies to Rip DeepSeek Out of Government Systems
The U.S. Department of Homeland Security on Monday ordered civilian federal agencies to remove DeepSeek products and third-party services built on the model from their IT systems, and to stop buying them. The notice warns that using DeepSeek may transfer sensitive data to China and could produce intelligence on U.S. persons and agencies. The Commerce Department, the Navy, and the states of New York, Tennessee and Virginia had already restricted DeepSeek. The FCC votes on October 29 on barring Chinese labs from testing electronics for U.S. use.
- Tesla-SpaceX merger is 'not so easy': Analyst
Speculation about a possible merger between SpaceX (SPCX) and Tesla (TSLA) has grown on Wall Street in recent weeks. RBC Capital Markets analyst Tom Narayan says it would not be simple: SpaceX would have to acquire Tesla, likely in an all-stock deal, and would need to pay a strong premium. He sets a $480 price target for Tesla, while the shares trade near $367. The longer-term focus may be Terafab, Elon Musk's chip initiative aimed at cutting production costs by up to 90% and bypassing Nvidia and TSMC. Musk currently controls 85% of SpaceX's voting rights and 20% of Tesla's.
- Is Nvidia (NVDA) Stock Priced Right?
Chip stocks fell sharply last week, and Nvidia (NVDA) dropped nearly 2% as investors worried that heavily indebted AI companies would face higher borrowing costs after bond yields jumped for CoreWeave, a cloud company Nvidia backs. CoreWeave shares had fallen more than 15% the day before. Nvidia's own numbers show no sign of that stress: it sold $96.2 billion of chips and systems in the quarter ended July, up 106% from a year earlier, mostly from data center sales. Its net profit margin was 63.66% over the past 12 months, and management expects $108.0 billion in revenue next quarter, assuming no data center sales to China. The key risk is whether customers can keep paying for chips if interest rates stay high, and the planned partnerships to bring over $500 billion of outside capital into AI infrastructure have not yet become definitive agreements.
- Networking Stocks Rally as Tech Rebound Lifts AI Gear Makers: Ciena and Arista Climb 4%, but Cisco Barely Moves
Networking stocks rallied with the tech rebound as suppliers of AI data center gear drew buying: Ciena (CIEN) rose 4% to $347.48 and Arista Networks (ANET) climbed 4% to $183.32, well ahead of the iShares U.S. Technology ETF (IYW) at 1.29% and the Invesco QQQ Trust (QQQ) at 1.31%, while Cisco (CSCO) was practically unchanged at $107.06. Ciena's fiscal Q3 2026 adjusted EPS was $2.11 against a $1.73 consensus, with revenue up 37% year over year to $1.67 billion, and it raised fiscal 2026 revenue guidance to $6.42 billion. Its backlog reached $8.5 billion, but supply remains the limit, and management does not expect the market to return to balance before 2028. Two customers made up 41.7% of Q3 revenue, so Ciena's growth is concentrated. The next test is whether Ciena can hit its fiscal Q4 2026 revenue guidance of $1.75 billion under tight component supply.
- Gartner Predicts “80% of Neoclouds” Out of Business by 2030: Here’s Who Wins
Gartner forecast on October 14 that more than 80% of neoclouds will stop operating independently by 2030, and CoreWeave (CRWV) fell 25% last week. The article argues that hyperscalers funding AI capacity from their own cash flow, led by Amazon and Alphabet, are likely winners as credit tightens for indebted neoclouds. Amazon generated $140 billion of operating cash flow in fiscal 2025, more than covering $132 billion of capex, while CoreWeave's total debt reached $29.8 billion. Since their July 29 closing low, Microsoft, Alphabet and Amazon are up 15.6%, compared with 1.6% for IREN, CoreWeave and Nebius. Hyperscaler earnings in the coming weeks will need to show whether sold-out capacity is turning into results.
