Sandisk (SNDK) stock has risen 3,700% since its formal separation from Western Digital in February 2025. The gain was driven by surging demand for flash storage from AI data centers, inclusion in the Nasdaq-100 and S&P 500, and net income of over $11 billion in fiscal 2026, compared with a $1.6 billion loss the year before. With a P/E ratio of 19 and a forward P/E of 6.3, the article notes that memory and storage stocks have historically faced sharp sell-offs once booms end, so investors should approach the stock with caution. The author says the stock is more likely to pull back than rise over time, though it could keep climbing if revenue forecasts prove accurate.

- Cramer warns SanDisk and Western Digital are worst stocks if data center capacity shrinks
Jim Cramer warned on October 19 that SanDisk and Western Digital, two storage stocks with large year-to-date gains, would be the worst holdings if fewer data centers are built. SanDisk closed at $1,371.12, up 5.53%, and Western Digital rose 6.09% to $352.21, though both had fallen sharply over the past month. The article says both companies sell commodity-priced NAND flash and hard drives, with price increases driving much of recent growth and no recurring billing from installed customers to cushion a slowdown. SanDisk's prepayment-backed agreements with eight customers guarantee at least $93.9 billion in revenue at floor pricing, but most of its sales still move with market prices. The bullish case rests on Microsoft's capex of $115.948 billion in fiscal 2026 and expected $175 billion in fiscal 2027, spending levels that Microsoft itself controls.
- Prediction: Sandisk Stock Will Soar After Oct. 29. Here Are 379 Billion Reasons Why
Sandisk (SNDK) has fallen 32% since early July after rising 858% in the first half of 2026, but the article argues the slide reflects concerns about the sustainability of AI infrastructure spending rather than the company's financial performance. Sandisk guided fiscal 2027 first-quarter revenue to $10.3–$10.8 billion and non-GAAP EPS to $45.00, implying 357% year-over-year revenue growth at the midpoint. TrendForce expects NAND flash industry revenue to reach $379 billion in 2027, up 40%, and Counterpoint Research puts Sandisk's NAND market share at 11%. The stock trades at 8 times forward earnings versus 19 for the S&P 500. The author expects results due October 29 to beat expectations and could lift the stock.
- Why Sandisk Stock Shot Higher Today
Sandisk shares jumped as much as 8.3% and were still up 7.9% at 11:24 a.m. ET, helped by a tech rebound and positive news in high-bandwidth memory (HBM). Nvidia has developed NVHBM, a custom HBM die with 15% lower power consumption and 30% higher bandwidth that links NVLink and HBM chips. A Seoul Economic Daily report says Nvidia asked Samsung Electronics to use TSMC's 3-nanometer process to make NVHBM dies, the first such collaboration between the two. Nvidia has also approached Micron and SK Hynix to standardize the process, which could free compute-die space for up to 30% additional compute. The article argues this suggests AI adoption still has room to grow, which would also benefit memory suppliers, and notes Sandisk trades at 19 times earnings and 6 times forward earnings.
- Sandisk Stock Rebounds 6 % to Snap Seven - Day Losing Streak as Memory Chipmakers Recover From CXMT Fears
Sandisk shares rose 6.48% to $1,383.49 in Monday morning trading on the Nasdaq, ending a seven-session losing streak that began Oct. 8. The rebound came as memory chip stocks recovered from a sell-off driven by fears that China's CXMT is advancing its chip technology faster than expected, which could boost global supply and pressure prices. Some analysts argue the threat to Sandisk is overstated, since CXMT's advances mainly concern DRAM while Sandisk focuses on NAND flash. Even after the gain, the stock remains about 40% below its record close of $2,335 in late June, though it is up nearly 780% over the past year on AI data center memory demand. Of 17 analysts covering it, 15 rate it Buy and two rate it Hold, with an average target of about $2,206; the company reports quarterly results on Oct. 29.
- Sandisk and Camping World have been highlighted as Zacks Bull and Bear of the Day
Zacks names Sandisk (SNDK) its Bull of the Day and Camping World (CWH) its Bear of the Day, and also analyzes Tesla (TSLA) and SpaceX (SPCX). Sandisk, rated Zacks Rank #1 (Strong Buy), reported fiscal fourth-quarter earnings of $39.25 per share, beating consensus by 14.63%, while revenue surged 371.6% year over year to $8.97 billion and non-GAAP gross margin reached 84.6%, up from 78.4%. Analysts forecast fiscal 2027 sales of $49.25 billion, and consensus estimates for both the current and next year have risen over the past sixty days. Camping World, rated Zacks Rank #5 (Strong Sell), faces higher borrowing costs and cautious consumers; four analysts lowered current-year earnings estimates in the past thirty days and none raised them. The consensus estimate fell from 36 cents to 20 cents per share, a decline of nearly 44%.
- The Best Growth Stock to Invest $10,000 in Right Now
Sandisk shares have surged 827% over the past year but dropped 44% from their June 22 52-week high, with fears over NAND flash demand, AI infrastructure spending and competition from China's CXMT. The author argues these fears are overblown, since CXMT doesn't make NAND flash and its DRAM technology reportedly trails Micron and SK Hynix. Enterprise SSD demand is booming on the back of the AI boom, with contract prices reportedly up 3x year over year, and McKinsey and IDC forecast annual growth of 35% and over 40% through 2030, respectively. Sandisk posted $20 billion in fiscal 2026 revenue with an 11% NAND market share, and its TAM is seen reaching $500 billion next year. The company targets mid-to-high teens annual revenue growth in fiscal 2028 to 2030 and a non-GAAP operating margin of 75% by fiscal 2030, versus 63% in fiscal 2026.

- Meta and Google About to Run the Old Playbook Again, Will “Sell Space Inside Their Models.”
Former Stability AI CEO Emad Mostaque says Meta and Google will sell space inside their AI models, so that a request for beer could return a Bud Light recommendation. The article notes that ad revenue lets Meta and Alphabet give AI away free, while rivals that rely on paying developers must charge; Meta reported $201 billion revenue in 2025 at a 41% operating margin, and Alphabet's operating margin was 32%. According to the article, Meta's Muse launch post says conversations are kept out of its ad systems, even though Muse became the #1 free app and has paid plans at $20 and $100 a month. The article argues that putting ads inside answers is a much bigger step than placing ads beside search results and could make users doubt recommendations, and notes Meta reports third-quarter results this week.
- Is Elon Musk Coming for Verizon?
A Motley Fool Hidden Gems podcast discusses SpaceX's wireless ambitions after a reported spectrum acquisition sent Verizon stock down about 10%. One host says his current service was about eight times faster than SpaceX's $55 offering, and doubts many users would accept the slower speeds and higher latency of satellite connections. The guests note the spectrum suits terrestrial networks better than satellites, that building one could cost 10 billion or more, and that mobile carriers are valued at less than two times sales. With roughly 11,000 satellites in orbit and an estimated 40,000 users per newer satellite, Starlink could theoretically serve hundreds of millions, but speed and capital expenditure remain open questions.
- Big Tech's AI spending has Wall Street worried
Dan Flax, Senior Research Analyst at Neuberger, discusses investor concerns over massive AI infrastructure spending by hyperscalers. He notes that cloud businesses are accelerating on AI workloads, but capital needs are rising, prompting debt issuance and an equity raise by Google earlier this year. On Meta, the company raised the low end of its total spending forecast to $135–145 billion this year and has about $825 billion in future spending commitments, which weighed on the stock. Flax argues the core digital advertising business still generates robust operating cash flow, and customers want to rent Meta's compute and use its models, so he expects more visible growth over the coming months that could ease market concerns.
- Senate Democrat Probes Tether Payments to Ex-White House Crypto Adviser’s Firm
Sen. Richard Blumenthal, D-Conn., asked Tether to provide records of its dealings with Bo Hines and his consulting firm Nxum by Nov. 3. The Wall Street Journal reported that Nxum earned $6.3 million from a Tether deal struck in May 2025, while Hines, who kept a one-third stake in Nxum, helped craft the GENIUS Act. A Nxum representative said Hines was not involved in the deal and received no Tether-derived funds while in government, and Tether said external counsel found no evidence of wrongdoing. Blumenthal argued the payment structure implicates federal ethics, anticorruption and lobbying laws.
