First Chip Rebound in Nine Sessions as Amazon Jumps 5% on AWS Outlook
Market Mood
Wall Street recouped part of last week’s AI sell-off in a single session. The Nasdaq Composite rose 1.11%, the S&P 500 gained 0.41% and the Russell 2000 added 0.25%, while the Dow slipped 0.07%.
The VIX fell 7.75% to 18.44. With Tesla and Meta due to report after the close on Wednesday, buyers did not chase the move far.
Friday's Checkpoints, Revisited
Friday’s note listed three things to watch. The semiconductor ETF did not fall below $493.39 and closed up 1.73% at $501.93. WTI held above $100 at $103.66, and the 10-year yield stayed near 5.1% at 5.14%.
All three held, but the oil reading is weaker evidence than it looks. That price belongs to an expiring contract, as the oil section explains.
Chips Rose for the First Time in Nine Sessions
The semiconductor ETF rose 1.73%, ending a nine-session losing streak. Nvidia gained 1.38%, Broadcom 1.78%, AMD 1.76%, TSMC 1.84% and Micron 2.97%.
Reuters reported that AI-linked stocks bounced back after a bruising sell-off with big earnings ahead. One session does not repair last week’s losses, though.
Sandisk Led the Gainers
Among the stocks we follow, Sandisk rose the most, 5.53% to $1,371.12. Its trading value of about $11.6 billion was also the largest of the day among our added names.
Yahoo Finance noted that Sandisk fell roughly 18% last week as memory stocks slid back into a bear market. Against that drop, this is one big bounce day rather than a new trend.
Intel Rose on a JPMorgan Upgrade
Intel rose 2.43% to $92.03. JPMorgan analyst Harlan Sur raised it from Underweight to Neutral, citing growing agentic AI workloads and tight supply of advanced chips.
He also said server share losses are likely to continue for a while. Note that the upgrade is to Neutral, not Buy.
Amazon Rose 5% on AWS Outlook
Amazon rose 4.98% to $262.45. Morgan Stanley named it a top pick and raised its price target to $350 from $335. Analyst Brian Nowak lifted his 2027 AWS revenue growth forecast to 47% from 41%.
The basis was Nvidia’s disclosure that it expects AWS to buy and deploy about 2 million of its GPUs over two years. Amazon reports third-quarter results after the close on October 29.
CoreWeave Could Not Hold Its Upgrade
CoreWeave, down 25% last week, closed 0.44% lower at $61.12. Goldman Sachs upgraded it from Neutral to Buy while cutting the price target to $106 from $139, arguing the market overstates financing risk.
MoffettNathanson stayed at Neutral the same day, cutting its target to $89 from $107 and warning of staggering financial obligations. The stock rose more than 3% intraday before giving it back, so worries over debt-funded AI capacity are not settled.
Oil: $103 Belongs to an Expiring Contract
WTI rose 2.22% to $103.66 a barrel, the highest settlement since September 15. But that contract was expiring; the more active December contract settled at $98.54, down 0.5%. Brent fell 0.3% to $109.55.
President Trump waived some Russia sanctions, yet Reuters noted that uncertainty over timing and duration limits confidence in more supply. Gold fell 0.5% to $4,160.1 an ounce.
The 10-Year Yield Rose to 5.14%
The 10-year Treasury yield closed at 5.14%, up 0.04 percentage point, and the 30-year was 5.47%. CNBC reported the 10-year dipped to around 5.09% during the day.
The Fed meets on October 27-28. As noted last week, markets still price some chance of a hike, so Monday’s rally does not look like relief from rates.
Coinbase, Deere and Merck Fell
Seven of the stocks we follow fell: Coinbase 2.72%, Deere 2.32%, Merck 1.59%, Meta 0.55%, CoreWeave 0.44%, Apple 0.15% and Walmart 0.09%.
Merck and Walmart, last week’s defensive havens, slipped, which suggests money moved back toward tech.
Tesla and Meta Report Wednesday
Tesla closed up 3.76% at $368.06 and Meta down 0.55% at $705.44. Both report after the close on October 21. Reuters said Tesla and SpaceX results will test Musk’s AI spending ambitions.
Microsoft and Alphabet report on the 28th, Amazon and Intel on the 29th. The numbers that show whether AI spending turns into profit start arriving this week.
Korean Chipmakers Already Fell Hard
SK Hynix and Samsung fell 24.3% and 17.8% last week after China’s CXMT announced DDR5 modules. Monday’s gains in Micron and Sandisk give some reason to expect a partial rebound.
But Micron rose only 2.97% and the chip ETF 1.73%. Whether foreign buying persists matters more than the opening price.
Valuation: Micron at 4.4 Times Earnings
On next year’s expected earnings Micron trades at 4.4 times, and 46 analysts’ targets sit 72.5% above the price. It is 27.9% below its 52-week high. Nvidia trades at 13.6 times, with targets 51.4% higher.
Beginner’s note: P/E divides the share price by earnings per share; lower means you pay less for the same profit. Memory chipmakers often look cheapest when profits peak, so we do not call it cheap on one number.
What to Watch Next Session
First, whether the semiconductor ETF holds above Monday’s $501.93 close. Second, whether the 10-year yield stays near 5.1%. Third, whether December WTI stays near $98. Tesla and Meta report after the close on the 21st.
What We Learned Today
Berkshire Added Heavily to Alphabet by End of June
Large US funds disclose their holdings each quarter in 13F filings. The latest filing is as of June 30, 2026, and Berkshire Hathaway raised its Alphabet Class A stake by 45% and Class C by 658%. It added 44% to Delta Air Lines and trimmed Bank of America by 6%.
13F filings come out 45 days after the reporting date, so they show last quarter’s traces, not current positions.
| Alphabet Class A (Berkshire) | +24,541,369 shares (+45%) |
| Alphabet Class C (Berkshire) | +23,603,218 shares (+658%) |
| Delta Air Lines (Berkshire) | +17,510,544 shares (+44%) |
| Bank of America (Berkshire) | -30,230,150 shares (-6%) |
Fermata’s Take
We do not read Monday’s rebound as a sign that last week’s decline is over. The chip ETF rose 1.73% for the first time in nine sessions, yet the 10-year yield rose to 5.14% and CoreWeave fell despite an upgrade, so there is no sign that worries over debt-funded AI capacity have eased. Our principle on days like this is to listen to Tesla’s and Meta’s capital spending commentary on Wednesday and see whether the chip ETF holds $501.93 before we change our view.
Check · 2026-10-21 — Whether the semiconductor ETF (SOXX) holds above its $501.93 close after Tesla and Meta report on the 21st, whether the 10-year yield stays near 5.1%, and whether December WTI stays near $98.
