Sandisk Corporation

SNDK · Nasdaq
Sandisk sells NAND flash memory and storage products, including enterprise SSDs, to customers serving data-center, Edge and other storage needs. It earns revenue from product sales; the evidence highlights Data Center and Edge demand but does not provide a revenue breakdown by business or product. Long-term customer agreements and disciplined supply management are part of its commercial approach. Reported FY2027 revenue is $20.2 billion and net income is $11.4 billion, compared with FY2025 revenue of $7.4 billion and a net loss of $1.6 billion. The supplied figures show a sharp improvement in reported scale and profitability, but do not specify customer counts or unit volumes.
Sandisk gained 5.48%, from $1,260.93 to $1,330.05, over the stated week. Trading was uneven: after closing at $1,255.58 on Monday, shares rose 3.9% Tuesday and another 7.7% Wednesday to $1,404.77, then fell 5.3% Thursday, giving back much of Wednesday’s advance. The clearest company-specific support in the supplied evidence is Sandisk’s fiscal Q1 2027 earnings beat—earnings topped estimates by 5.34% and revenue by 3.24%—alongside reports of sharply higher revenue and AI-driven data-center and Edge demand. A Motley Fool report also attributes a Sandisk rally to record growth at competitor SK Hynix. The evidence does not identify a specific Thursday catalyst for the reversal.
Sandisk fell 7.81% over the reported span, from $1,487.33 on October 12 to $1,371.12 on October 19. The stock slipped on October 13, then dropped nearly $79 on October 14 as coverage cited mounting worries about AI-related costs and data-center delays. It continued lower on October 15, when trading volume rose to 13.3 million shares, amid a broader selloff in chip stocks, and fell another 6.8% on October 16 to $1,299.30. Monday’s 5.5% rebound, which TipRanks linked to SpaceX-related news, recovered only part of the prior declines. The supplied evidence points to sector and spending concerns, not a specific Sandisk announcement, as the main pressure.
Sandisk fell 12.72% over the stated week, from $1,704.16 to $1,487.33. The decline extended a broader memory-stock selloff: coverage cited worries about AI demand after Anthropic-related concerns and an earnings-related semiconductor retreat following ASML’s quarterly revenue miss. Fresh competitive pressure from China’s CXMT added to fears that the memory supercycle could weaken, while Rosenblatt called the CXMT-driven selloff overblown. Shares briefly rebounded on October 7, but fell again over the next three sessions and dropped further on October 12. A reported data-storage partnership with Meta and a $93.9 billion contract book offered counterpoints to the demand concerns, but did not prevent the decline. The supplied evidence does not establish the precise timing of each headline relative to the daily moves.
SNDK fell 4.01%, from $1,729.76 to $1,660.46 across the supplied endpoint interval. The shares first rose, gaining 0.59% on September 30 and 2.75% on October 1, then reversed sharply with a 3.79% drop on October 2 and further losses on October 5 and 6. The evidence does not identify a company-specific event that explains the decline; coverage instead flags broader memory-sector concerns, including Toshiba-related storage fears. Mizuho raised its price target to $2,050 from $1,875 on October 6, but the stock fell that day, and the available evidence does not establish that the target change drove trading. No earnings release or contract announcement is identified as a weekly catalyst.
Sandisk gained 1.94%, from $1,753.62 to $1,787.69 over the supplied measurement window. The stock fell 3.65% on Monday, September 28, as worries that OpenAI could slow the pace of AI development weighed on shares; the broader market was also under pressure as bond yields rose. It then recovered across the next three sessions, with gains on Tuesday and Wednesday followed by a 2.75% jump on Thursday, October 1. The Thursday advance came as bond yields fell and major U.S. indexes rebounded, while investors also looked toward Micron’s upcoming results for signals about memory demand. Sandisk finished above the supplied starting close, although the September 28 drop was material.
Sandisk rose 19.51%, from $1,519.97 on September 16 to $1,816.57 on September 23, though the supplied prices extend beyond the stated September 21 week start. It climbed to $1,791.82 by September 18, slipped to $1,766.64 on September 21, surged to $1,887.04 on September 22, then fell 3.73% to $1,816.57 on September 23. The evidence does not identify a company-specific announcement behind the advance or the late pullback. Coverage frames Sandisk within the AI-memory and storage trade, while Barchart reported broad U.S. equity declines on September 23 as the 10-year Treasury yield reached a 19-year high; that market pressure coincided with, but does not establish the cause of, Sandisk’s decline that day.
Sandisk rose 10.93%, or $171.29, from $1,566.70 to $1,737.99 over the supplied window. The move was concentrated in Friday’s session, when the stock jumped 11.90% from $1,554.99 to $1,740.00 on 16.6 million shares, after modest declines on Tuesday and little change on Wednesday and Thursday. It then gave back only $2.01 on the next reported close. The evidence does not identify a company-specific announcement, earnings release, contract, or guidance change driving the surge. Instead, coverage linked the broader move to enthusiasm for AI-related storage demand, while separate reports described profit-taking in storage stocks after a large prior run. SanDisk therefore outperformed on sector momentum rather than a documented new corporate catalyst.
Sandisk rose $70.04, or 4.72%, over the week to $1,554.99. The advance was concentrated on Monday, when the stock jumped to $1,566.70 on volume of 23.4 million shares, before giving back part of that gain on Tuesday and then stabilizing with modest increases on Wednesday and Thursday. The supplied evidence does not identify a company-specific announcement during the week. Instead, coverage points to sector enthusiasm around accelerating NAND pricing, stronger AI-related memory demand, and bullish earnings revisions, with Micron also rising in the cited trading coverage. Lynx Research’s positive view and broader discussion of Sandisk’s post-earnings momentum likely reinforced sentiment, while the announced Citi and Goldman Sachs presentations were upcoming rather than events during the week.
Sandisk fell 6.96% over the week, from $1,596.08 to $1,484.98. The stock dropped sharply on Monday to $1,493.12 on nearly 14.0 million shares and slipped again Tuesday, with no clearly identified company-specific catalyst in the supplied evidence. It rebounded 1.25% Wednesday as Nvidia-driven AI optimism lifted semiconductor stocks, but gave back most of that gain Thursday and finished essentially flat Friday. Kioxia’s Thursday announcement of more than $31 billion of planned investment with Sandisk in Japan through 2032, subject to government support, did not prevent the decline. Broader trading was mixed around expectations for Fed Chair Warsh, while crude-related moves in bond yields also influenced the market.
Sandisk fell 3.89% over the supplied interval, from $1,288.03 to $1,237.92. The stock initially surged 10.82% on August 4, as Investor Day coverage highlighted a bullish growth outlook, an AI-related flash opportunity, a margin-overhaul plan and potential cash returns; JPMorgan also upgraded the shares. That gain reversed sharply over the next three sessions, including a decline after coverage emphasized management’s warning that margins would fall. The stock closed at $1,212.21 on August 7 before rebounding 2.12% on August 10. The reversal indicates that enthusiasm over longer-term demand and capital allocation was outweighed during most of the period by concerns about near-term profitability and the stock’s volatility.
Sandisk rose $331.52, or 30.25%, from $1,096.10 to $1,427.62 over the week. Trading was volatile: the stock fell to $1,015.89 on July 29 before rebounding 26% on July 30, then consolidated on July 31 and advanced again on August 3-4. The main company-specific catalyst was coverage that Sandisk and SK Hynix are collaborating to promote High Bandwidth Flash, reinforcing expectations for an AI-memory opportunity. Broader memory optimism, including persistent DRAM supply-demand imbalance commentary and favorable Apple-related demand implications, added support. Strong technology-market momentum also mattered: the Nasdaq 100 rose 3.32% and the S&P 500 gained 1.79% on August 4.
