Updated 27 October 2026. Sandisk (NASDAQ: SNDK) closed Monday at $1,255.58, up $17.55 or 1.42 percent, after trading between $1,229.00 and $1,287.84 on about 6.7 million shares (Gotrade; Yahoo Finance). Two sessions remain before fiscal Q1 FY27 results on Thursday 29 October after the close. Verdict: the memory tape turned firmly positive overnight. SK hynix jumped 6.4 percent and Samsung Electronics 4.5 percent in Seoul on Tuesday morning as Anthropic’s IPO filing revived the AI trade, and SK hynix itself reports before Wednesday’s Seoul open, which is Tuesday evening in New York. Seagate reports after Tuesday’s US close. Reference levels: $1,100 below, $1,430 above.
Key facts
- Price: SNDK $1,255.58 at Monday 26 October’s close, up from Friday’s $1,238.03; open $1,251.88, range $1,229.00-$1,287.84, volume 6.7 million shares, about 22 percent below the 30-day average. Market value about $183.8 billion; the stock is 46.7 percent below its 52-week high of $2,354.39 (Gotrade).
- Why it rose: no Sandisk-specific news; the move was part of a memory and chip rally in which Micron gained 2.98 percent, Intel 4.04 percent and Nvidia 2.39 percent (Gotrade). The Philadelphia Semiconductor Index rose 2.82 percent (Seoul Economic Daily).
- Seoul on Tuesday: SK hynix rose 6.43 percent to 1.357 million won and Samsung Electronics 4.46 percent to 222,500 won at 9:20 am KST; the Kospi opened 3.46 percent higher and moved back above 5,700, with foreigners net buyers of 156.2 billion won early in the session. The paper tied the rally to Anthropic’s S-1 filing, which showed first-half revenue of $16.29 billion (Seoul Economic Daily).
- Contracts: Bank of America analyst Vivek Arya wrote that memory customers’ supply deals now run three to five years, against a year or less before, and the bank expects tight memory availability in 2027 and 2028 (24/7 Wall St., via Gotrade).
- The print: fiscal Q1 FY27 results on Thursday 29 October after the close, call at 1:30 pm PT (Sandisk IR). Guidance is non-GAAP EPS of $44-$46 on revenue of $10.3-$10.8 billion. Consensus EPS sits at or above the top of that range: $45.22 at Barchart, $46.11 at TipRanks and $46.22 at Admiral Markets, on revenue near $10.64 billion (as gathered on 26 October).
- Implied move: sources differ. TipRanks priced 12.1 percent either way as of 23 October; Investing.com’s model, using Bloomberg options data, 7.7 percent; Earnings-Watcher 13.7 percent as of 16 October. The honest reading is a range of roughly 8-14 percent.
- Analysts: StockAnalysis showed a Buy consensus from 25 analysts with an average target of $2,143.83 as of 23 October; BNP Paribas Exane’s $1,400 is the lowest recent bank target.
Two verdicts tonight
Sandisk’s own numbers come on Thursday, but two read-throughs land before then. Seagate reports its fiscal first quarter of 2027 after the US close on Tuesday, with a call at 5 pm ET (Seagate), against prior guidance of about $4.1 billion of revenue and $7.30 of non-GAAP EPS at the midpoint. Its comments on component costs are the buyer’s view of NAND pricing, the same lens through which Western Digital fell after its beat. A few hours later SK hynix publishes its third quarter before 9 am Seoul time on Wednesday, 8 pm on Tuesday in New York, against FnGuide consensus of 76.96 trillion won of operating profit (MoneyToday). Its NAND commentary sets Sandisk’s Wednesday open.
The Seoul rally raises the bar for both. SK hynix’s 6 percent jump on Tuesday morning prices a strong report before it is out, and Mirae Asset Securities’ Seo Sang-young warned that the more a stock already reflects accelerating investment and high profit growth, the greater the risk of a valuation reset when that growth slows (Seoul Economic Daily). Sandisk is about 47 percent below its 52-week high, so the market has already marked down the multiple once; Thursday’s guide decides whether that was enough. Monday’s page covered Elon Musk’s warning on AI-operator funding; the DRAM side of the week is on the Micron page.
Sandisk into results: bull, base and bear
| Scenario | SNDK | What has to happen | Anchor |
|---|---|---|---|
| Bear | $1,100 | SK hynix or Seagate flags NAND price moderation, the Fed leans hawkish, and Sandisk’s next-quarter guide lands inside consensus. | About 12 percent below Monday’s $1,255.58, the downside of TipRanks’ 12.1 percent implied move. |
| Base | $1,160-$1,350 | The stock trades the Seoul and Seagate read-throughs, Sandisk beats the quarter and guides in line; the reaction stays inside the options range. | Roughly Investing.com’s 7.7 percent implied move either side of Monday’s close. |
| Bull | $1,430 | SK hynix confirms NAND prices still rising into 2027 and Sandisk guides above consensus while holding gross margin. | About 14 percent above Monday’s close, the upside of Earnings-Watcher’s 13.7 percent implied move. |
The bear case sits below Monday’s close. These are reference levels measured from the verified quotes, not forecasts.
What to watch this week
- Tuesday: whether SNDK follows Seoul’s memory rally at the US open.
- Tuesday after the close: Seagate’s results and its comments on component costs.
- Tuesday 8 pm ET: SK hynix’s third quarter against the 76.96 trillion won consensus and its NAND outlook.
- Wednesday 2 pm EDT: the Fed decision; December-hike language matters for richly valued AI hardware.

Quick take: Sandisk closed at $1,255.58 on Monday, up 1.4 percent, and Seoul’s memory stocks jumped on Tuesday after Anthropic’s IPO filing. Seagate and SK hynix both report before Wednesday’s US open. Options price an 8-14 percent move on Thursday.
