Sandisk Corporation (NASDAQ: SNDK) has become one of 2025’s most dramatic stock stories. Spun off from Western Digital earlier this year, the flash-storage specialist has ridden the artificial intelligence (AI) infrastructure boom, a string of strong earnings, and a fast-track promotion into the S&P 500 index. [1]
Since April, SNDK has surged from an all‑time low near $27.89 to recent levels around the $240 mark, with a peak above $280 in November — a gain of more than 700% from the low and over 500% year‑to‑date. [2]
This article rounds up current news, forecasts and analysis on Sandisk from and after November 21, 2025, and explains what they may mean for investors following the stock on Google News or Discover.
1. Snapshot: Where Sandisk Stock Stands Today
Recent trading data show just how volatile the ride has been:
- Latest price (Dec 11, 2025): about $241.39, up 3.66% on the day. [3]
- Market cap: roughly $34.1 billion, up nearly 10% over the past week. [4]
- 52‑week range:
- Low: $27.89 (April 7, 2025)
- High: $284.76 (November 12, 2025) [5]
- Volatility: about 7.9% with a beta of 2.31, meaning SNDK tends to move more than twice as much as the broader market. [6]
From November 21 onward, the stock has swung between roughly $180 and $240, including double‑digit daily moves as investors digest new earnings guidance, analyst upgrades and index‑related flows. [7]
2. Why November 21, 2025 Was a Turning Point
2.1 Price action and options surge
On November 21, 2025, Sandisk closed near $200.27, up about 2.2% on very heavy volume after a brutal 20% drop the previous day. [8]
That same day, options data showed 48 “unusual” large trades in SNDK:
- 31 put contracts worth about $2.32 million
- 17 call contracts worth about $1.48 million
- Flows were roughly balanced between bullish and bearish, signalling traders were positioning for big moves, not quiet consolidation. [9]
Day‑trading commentary highlighted SNDK as a momentum name, noting the stock was trending higher intraday by nearly 4% at one point despite the prior day’s crash. [10]
2.2 Wall Street starts talking about more upside
Also on November 21, a Zacks Equity Research note asked whether Sandisk could rally another ~34%, based on the gap between its then‑current price and consensus 12‑month analyst targets. [11]
A day earlier, separate analysis on Yahoo Finance flagged that Sandisk’s share price had “drifted slightly” after a blistering run but was still trading on elevated valuation metrics, reflecting expectations of sustained growth from AI‑driven demand. [12]
From that date onward, the conversation around SNDK shifted away from “Is this rally real?” toward “How much further can it go — and what could derail it?”
3. Fundamentals: Earnings Momentum and Fab Cost Growing Pains
3.1 Spin‑off and Q4 2025 results
Sandisk became a standalone, publicly traded company on February 21, 2025, when Western Digital completed the spin‑off. [13]
The company’s first major milestone as an independent entity came with fiscal Q4 2025 results on August 14:
- Revenue:$1.90 billion, up 12% sequentially and above the guidance range.
- GAAP net loss:$23 million, or –$0.16 per share.
- Non‑GAAP EPS:$0.29.
- Guidance for Q1 2026: revenue $2.10–$2.20 billion, Non‑GAAP EPS $0.70–$0.90. [14]
However, markets focused on the lower‑than‑expected profit outlook, largely due to higher startup costs at new fabrication facilities. An Investopedia report noted that estimated fab startup expenses climbed to $60 million from $42 million in the prior quarter, helping to knock the stock down about 5% after the guidance. [15]
3.2 Q1 2026: Back to profitability with accelerating growth
On November 6, 2025, Sandisk reported fiscal Q1 2026 results — a key catalyst for the renewed rally that framed the post‑November 21 story:
- Revenue:$2.31 billion,
- up 21% sequentially and 23% year‑over‑year. [16]
- GAAP net income:$112 million ($0.75 per diluted share), swinging from a loss the prior quarter.
- Non‑GAAP EPS:$1.22 (up more than 300% quarter‑over‑quarter). [17]
- Gross margin:29.8%, up 3.6 percentage points from Q4.
- Datacenter revenue: up 26% sequentially, with multiple hyperscaler customers in qualification or planned onboarding in calendar 2026. [18]
- BiCS8 NAND accounted for 15% of bits shipped, and is expected to become the majority of production exiting fiscal 2026. [19]
For Q2 2026, management guided to:
- Revenue:$2.55–$2.65 billion
- Non‑GAAP EPS:$3.00–$3.40
- Non‑GAAP gross margin: roughly 41–43%. [20]
In short: the business has rapidly moved from losses and heavy startup costs to profitable growth, with a clear roadmap tied to higher‑margin AI storage products.
4. AI Storage Tailwind: Why the Market Is Paying Up
Several recent analyses converge on the same theme: AI and cloud workloads are reshaping the NAND flash market, and Sandisk is one of the clearest pure‑play beneficiaries.
- A Zacks commentary on Western Digital and Sandisk highlighted that AI‑powered storage markets are “exploding,” projecting the AI storage segment around $30+ billion in 2025 and emphasising Sandisk’s leverage to higher‑capacity NAND and advanced architectures. [21]
- Forbes traced SNDK’s 2025 surge to unexpected strength in AI and cloud infrastructure demand, which has tightened supply and helped push NAND pricing higher. [22]
- A recent industry note argued that Sandisk is not just “riding” the AI wave but engineering key enablers, pointing to a ~23% revenue jump, a roughly 50% uplift in NAND pricing and new technologies such as High Bandwidth Flash (HBF) designed for AI inference. [23]
This backdrop has made SNDK part of a small group of “AI storage champions”, often mentioned alongside Micron and Western Digital in discussions of which chip stocks are leading the S&P 500 in 2025. One analysis noted Sandisk’s share price had jumped over 500% this year, compared with roughly 275% for Western Digital. [24]
5. S&P 500 Inclusion: From Small‑Cap to Index Heavyweight
One of the biggest headlines after November 21 has been Sandisk’s rapid rise into major equity benchmarks.
5.1 Official S&P 500 promotion
In late November, S&P Dow Jones Indices announced that Sandisk Corp. would leave the S&P SmallCap 600 to join the S&P 500, replacing Interpublic Group, which is being acquired by Omnicom. [25]
Key details:
- Effective November 28, 2025, before the market open. [26]
- Sandisk’s market cap was roughly $33 billion, already far too large for the small‑cap index. [27]
- The stock jumped more than 7% in after‑hours trading on the inclusion news, as index‑tracking funds and benchmarked managers prepared to buy shares. [28]
A follow‑up analysis noted that Sandisk was simultaneously added to several large‑cap benchmarks, including the S&P 500 Information Technology, S&P 500 Equal Weight and S&P Global 1200, cementing its status as a mainstream large‑cap tech stock. [29]
5.2 Market reaction since inclusion
Historical price data around the effective date show:
- Nov 28 close: about $223.28, up ~3.8% with heavy volume over 13 million shares. [30]
- Early December saw a sharp pullback to around $194, followed by a rapid rebound back above $230 and then to the $240s by December 11. [31]
This pattern — a spike on inclusion, profit‑taking, then renewed buying — is typical of S&P 500 entrants, as passive index funds accumulate stock while active managers rebalance.
6. Analyst Ratings and Price Targets After November 21
6.1 Consensus: more upside, but not the 5x kind
Multiple data providers now track Sandisk’s analyst coverage:
- Average 12‑month price target:
- Around $262–273, implying roughly 10–20% upside from recent prices. [32]
- Fintel / Nasdaq (Nov 16): average one‑year target $259.46, an increase of 130% from the prior estimate of $112.47, with individual targets ranging from $96.96 to $329.70. At that time, the target was only about 2% above the share price, indicating that the stock had already caught up with earlier forecasts. [33]
- TipRanks: lists an average target of $262.71 and calls for around 16–20% upside, based on current analyst ratings. [34]
In short, Wall Street is still bullish, but the expected gains are now incremental, not another 500% melt‑up.
6.2 Major upgrades in recent weeks
Since mid‑November, several high‑profile analysts have pushed targets higher:
- Bank of America has repeatedly raised its target on SNDK in 2025. Earlier in the rally it more than doubled its target from $59 to $125, citing booming AI‑driven demand for NAND flash. [35]
- A more recent note from BofA (summarised by GuruFocus) reported analyst Wamsi Mohan lifting his target from $270 to $300, while maintaining a Buy rating. [36]
- Morgan Stanley raised its SNDK target to $273 and kept an Overweight rating, arguing that intensifying memory shortages in both DRAM and flash should support earnings revisions higher in 2026. [37]
- UBS, Citigroup and Wells Fargo have all raised price objectives dramatically over the last two months, in some cases boosting targets from double‑digit to low‑$200s levels as the stock ripped higher. [38]
A Zacks “Bull of the Day” piece on December 1 highlighted a particularly aggressive earnings reset: consensus EPS for next year jumped from $10.39 to $24.04, a 130% increase, as analysts baked in stronger margins and AI‑related demand. [39]
6.3 Revenue and earnings forecasts for 2026
Looking further out:
- A Simply Wall St forecast now has 15 analysts projecting $10 billion in Sandisk revenue in 2026 — about 28% higher than the last twelve months — and expects losses to flip to EPS of $9.30 per share that year. [40]
- TradersUnion modelling suggests SNDK’s share price could trade between roughly $364 and $445 by the end of 2026, with an average estimate around $404, and a longer‑term scenario that reaches the high‑$800s by 2029–2030. [41]
- Several quantitative forecast sites (CoinCodex, TradingView and others) project near‑term upside of around 13–15% into early January 2026, but also note relatively high volatility in the last 30 days. [42]
These numbers vary widely, but the direction is consistent: expectations for revenue and earnings have been moving up, not down, since November 21.
7. Short‑Term Trading Outlook: Volatility Rules
Recent options and technical data suggest that traders should still expect big swings:
- Options‑implied “expected move” estimates for popular SNDK expiries into January 2026 cluster around ±23–25%, meaning the options market is pricing in the possibility of a roughly one‑quarter move up or down over the next five to seven weeks. [43]
- Technical models tracked by CoinCodex show a bullish near‑term stance but with SNDK only logging green days about 47% of the time over the past month, and volatility above 10% in that period. [44]
- The November 20–21 whipsaw — a 20% drop followed by a bounce on massive volume and unusual options activity — is a good illustration of how quickly sentiment can flip in this name. [45]
In other words, even though the fundamental story has improved, Sandisk remains a high‑beta, high‑volatility AI play, not a sleepy blue chip.
8. Is Sandisk Stock Overvalued or Just Catching Up?
Not everyone is convinced SNDK’s parabolic move is sustainable.
- An October analysis titled “Growth or Bubble?” argued that while AI and NAND fundamentals are improving, there is a risk that Sandisk’s share price has run ahead of earnings, and that any normalization in pricing could trigger a sharp re‑rating. [46]
- Another valuation review around November 20 noted that SNDK had experienced a mild pullback but still traded at rich multiples versus historical levels, with much of the optimism already priced in. [47]
At the same time, more bullish takes emphasise that:
- The company has already turned a corner from losses to solid profitability in Q1 2026. [48]
- NAND pricing is firming thanks to constrained supply and AI‑driven demand, with several analysts describing the current memory cycle as a potential “historic upcycle.” [49]
- Index inclusion should structurally increase demand for the stock via passive flows and mandates tied to the S&P 500 and related benchmarks. [50]
The debate now is less about whether Sandisk is a real business (the earnings prove that) and more about how much growth is already reflected in a share price that has multiplied several times this year.
9. Key Risks Investors Are Watching
From a risk perspective, recent news and analysis highlight several themes:
- Cyclical memory downturns
NAND flash is notoriously cyclical. If AI infrastructure spending slows or competitors overbuild capacity, pricing and margins could retreat, undercutting today’s bullish forecasts. [51] - Fab startup costs and capital intensity
Sandisk is ramping advanced fabs and technologies like BiCS8 and HBF. The Q4 2025 guidance shortfall was driven in part by a jump in fab startup costs, which hit $60 million and could rise further if timelines slip. [52] - Valuation risk after a 5x move
After a 500%+ rally in under a year, even small disappointments — a minor miss on guidance, softer AI commentary, or macro jitters — could trigger outsized drawdowns, as seen in the 20% drop on November 20. [53] - Competition from giants
Sandisk faces formidable rivals in NAND and AI‑oriented memory, including Micron, Samsung and SK Hynix. Morgan Stanley and others highlight that while shortages currently favour suppliers, competition could intensify as new capacity comes online. [54] - Market‑wide volatility and AI sentiment
SNDK’s high beta means it tends to amplify broad market moves, especially in AI‑linked sell‑offs, such as the sharp tech correction in mid‑November when several AI leaders dropped together. [55]
10. Bottom Line: What the Post–November 21 Story Says About SNDK
Putting it all together, here’s how Sandisk’s stock story looks today:
- Fundamentals are improving fast. Q1 2026 delivered strong revenue growth and a return to profitability, with guidance that implies further margin and earnings expansion. [56]
- AI infrastructure is the key growth engine. Demand from data centers and hyperscalers, combined with rising NAND prices, is powering the bull case and driving ongoing analyst upgrades. [57]
- S&P 500 inclusion has cemented SNDK as a core tech name. Index promotion brings more liquidity, visibility and forced buying from passive strategies. [58]
- Analysts still see upside, but expectations are now mature. Consensus targets cluster in the mid‑$260s to low‑$270s — implying double‑digit, not triple‑digit, percentage gains from here, with some outlier forecasts both higher and lower. [59]
- Risk and volatility remain high. Options markets are pricing large potential moves in the coming weeks, and previous pullbacks show how quickly sentiment can reverse in this stock. [60]
For investors tracking Sandisk Corporation (SNDK) stock on Google News or Discover, the message since November 21, 2025 has been clear:
Sandisk is now a mainstream AI‑storage heavyweight with real earnings power, major index backing and meaningful analyst support — but after one of the market’s wildest rallies of 2025, it is also a high‑volatility, high‑expectation name where both the upside and downside are amplified.
As always, any decision to buy, hold or sell SNDK should factor in your own risk tolerance, time horizon and broader portfolio — and not rely solely on analyst targets or short‑term forecast tools.
