Wall Street finished a choppy week in the red as risk-off sentiment took hold, driven by mounting concerns over stretched AI valuations and a sparse data calendar due to the ongoing government shutdown.

Adding to the caution, “Big Short” investor Michael Burry disclosed short positions against Nvidia (NVDA [https://seekingalpha.com/symbol/NVDA]) and Palantir (PLTR [https://seekingalpha.com/symbol/PLTR]). Crypto also slumped, with Bitcoin (BTC-USD [https://seekingalpha.com/symbol/BTC-USD]) sinking 6.9% and approaching both bear-market territory and the key $100,000 support level. Adding to the pressure, consumer sentiment weakened more than expected in November, according to the UofM Survey of Consumers data released on Friday.

Major indexes fell broadly: the Nasdaq Composite (COMP:IND [https://seekingalpha.com/symbol/COMP:IND]) dropped 3.0%, marking its worst week since April, while the Nasdaq 100 (US100:IND [https://seekingalpha.com/symbol/US100:IND]) slid 3.09%. The S&P 500 (SP500 [https://seekingalpha.com/symbol/SP500]) declined 1.6%, and the Dow Jones Industrial Average (DJI [https://seekingalpha.com/symbol/DJI]) slipped 1.2% as investors stepped away from high-growth stocks.

HERE’S WHAT DREW INVESTOR ATTENTION THIS WEEK:

PALANTIR TECHNOLOGIES (PLTR [https://seekingalpha.com/symbol/PLTR]) drew attention after reporting third-quarter results that topped expectations and lifting its full-year outlook. The company posted adjusted earnings of $0.21 per share, while revenue surged 63% year over year to $1.18B. Despite the strong results, the stock fell as analysts flagged valuation concerns.

SUPERMICRO (SMCI [https://seekingalpha.com/symbol/SMCI]) fell after posting its fiscal Q1 2026 results, which came in well below expectations. Quarterly revenue reached $5B, missing the $5.8B consensus by $800M and marking a 15% year-over-year decline. The company also reported an adjusted gross margin of 9.5%, slightly under the 9.6% estimate.

AMAZON (AMZN [https://seekingalpha.com/symbol/AMZN]) gained after Amazon Web Services (AWS) signed a seven-year, $38B deal with OpenAI (OPENAI [https://seekingalpha.com/symbol/OPENAI]) to access “hundreds of thousands” of Nvidia GPUs, with capacity to scale to tens of millions of CPUs for agentic workloads. AWS will provide OpenAI access to EC2 UltraServers, as the companies deepen collaboration to support large-scale AI infrastructure needs and growth of ChatGPT.

KIMBERLY-CLARK (KMB [https://seekingalpha.com/symbol/KMB]) shares fell after the consumer goods firm entered a deal to acquire all outstanding shares of Tylenol-maker KENVUE (KVUE [https://seekingalpha.com/symbol/KVUE]) in a cash and stock transaction. The deal values Kenvue (KVUE [https://seekingalpha.com/symbol/KVUE]) at an enterprise value of around $48.7 billion and is expected to deliver immediate value creation to its shareholders from $6.8 billion in upfront cash consideration.

NOVO NORDISK (NVO [https://seekingalpha.com/symbol/NVO]) said Saturday it will not raise its bid for METSERA (MTSR [https://seekingalpha.com/symbol/MTSR]) after PFIZER (PFE [https://seekingalpha.com/symbol/PFE]) emerged victorious in a hard-fought acquisition battle, securing a deal valued at up to $10B. Late Friday, Metsera announced a revised merger agreement under which Pfizer will acquire the company for up to $86.25 per share in cash, a proposal the board deemed superior amid rising antitrust concerns surrounding Novo’s offer. Separately, Novo Nordisk lowered its outlook for the fourth time this year on Wednesday, citing weaker-than-expected sales of its weight-loss treatments Wegovy and Ozempic.

PINTEREST (PINS [https://seekingalpha.com/symbol/PINS]) fell after its Q3 results and softer-than-expected Q4 outlook overshadowed a 17% revenue increase and continued user growth. For the fourth quarter, the company projected revenue of $1.31B–$1.34B, with the midpoint of $1.325B landing just shy of the $1.34B consensus. Pinterest also guided adjusted EBITDA to $533M–$558M, compared with expectations of $552.8M.

TESLA (TSLA [https://seekingalpha.com/symbol/TSLA]) drew attention as shareholders voted to reinstate CEO Elon Musk’s $1T compensation package, with about 75% supporting the plan at Thursday’s meeting. The package originally approved in 2018 remains tied to aggressive performance milestones, including major increases in Tesla’s market value, renewed growth in its core EV segment, and expansion into robotaxi and AI-driven robotics initiatives.

PINTEREST (PINS [https://seekingalpha.com/symbol/PINS]) shares fell after disappointing third quarter earnings coupled with below-consensus guidance for Q4. The social platform earned a profit of $0.38 per share, which improved from $0.32 a year ago but missed expectations by 4 cents. For the current quarter, Pinterest (PINS [https://seekingalpha.com/symbol/PINS]) expects revenue to be between $1.31B to $1.34B, with the midpoint of $1.325B coming up short of the $1.34B estimate.

ARISTA NETWORKS (ANET [https://seekingalpha.com/symbol/ANET]) fell despite reporting Q3 results that beat expectations, with revenue rising 27% Y/Y. For Q4, the company guided revenue to $2.3B–$2.4B (midpoint $2.35B vs. $2.33B consensus) and sees an adjusted gross margin of 62%–63% compared to the 63.2% estimate, alongside an adjusted operating margin of 47%–48%.

ARCHER AVIATION (ACHR [https://seekingalpha.com/symbol/ACHR]) released its Q3 results and unveiled several key initiatives, including an agreement to acquire control of Hawthorne Airport in Los Angeles for $126 million in cash. Archer (ACHR [https://seekingalpha.com/symbol/ACHR]) also raised $650 million in new equity during the quarter, boosting its total liquidity to over $2 billion. However, shares fell nearly 11% premarket as net losses widened to $129.9M in Q3, amid larger operating expenses.
