从约$28到约$725再回落至约$555：Q2非GAAP毛利率单季暴涨逾20个百分点至约51%、Q3指引营收约为市场预期的1.7倍、Citron做空攻击与Western Digital折价减持制造短期恐慌——NAND超级周期最强受益者的绝佳重仓窗口正在关闭
From about $28 to about $725 and then back down to about $555: Q2 non-GAAP gross margin surged by more than 20 percentage points in a single quarter to about 51%, Q3 revenue guidance came in at about 1.7 times market expectations, and short-term panic caused by Citron’s short attack and Western Digital’s discounted share sale — the exceptional heavy-position entry window for the strongest beneficiary of the NAND supercycle is closing.
2026年初，SanDisk发布Q2财报。
At the beginning of 2026, SanDisk released its Q2 earnings report.
营收同比增长约61%。非GAAP毛利率单季从约30%跃升至约51%。Q3营收指引约为华尔街当时预期的1.7倍。
Revenue grew about 61% year-over-year. Non-GAAP gross margin jumped from about 30% to about 51% in a single quarter. Q3 revenue guidance was about 1.7 times Wall Street’s expectations at the time.
股价盘后急涨，次日冲高至约$725历史峰值。
The stock surged sharply after hours and then climbed to a historical peak of about $725 the next day.
然后，两件事相继发生。
Then, two things happened one after another.
Western Digital宣布折价出售所持SanDisk大量股份，折价幅度约15%——原始股东的大规模清仓，引发市场恐慌性跟随抛售。与此同时，知名做空机构Citron Research公开建立空头头寸，发布看空报告，指控SanDisk估值严重泡沫化。
Western Digital announced the discounted sale of a large number of its SanDisk shares, at a discount of about 15% — the large-scale liquidation by the original shareholder triggered panic-driven follow-on selling in the market. At the same time, well-known short seller Citron Research publicly built a short position and released a bearish report, accusing SanDisk’s valuation of being severely bubble-like.
今天的股价：约$555。从约$725高点，回落约23%。
Today’s stock price: about $555. From the high of about $725, it has pulled back about 23%.
这是一个基本面驱动的故事，还是一个估值泡沫的破裂？
Is this a fundamentally driven story, or the bursting of a valuation bubble?
答案藏在Q3指引里。约65%至67%的非GAAP毛利率指引、非GAAP每股盈利约为刚刚过去这个破纪录季度的两倍——这是SanDisk用白纸黑字告诉市场：下一季度的利润，将远超刚刚创下历史纪录的这一季。
The answer lies in the Q3 guidance. Non-GAAP gross margin guidance of about 65% to 67%, and non-GAAP earnings per share at about twice that of the just-ended record-breaking quarter — this is SanDisk telling the market in black and white: next quarter’s profit will far exceed the quarter that just set a historical record.
Citron的看空攻击是情绪，Western Digital的减持是股东行为——两者都无法改变NAND供给结构性短缺的基本面现实。从约$28涨至约$725的那个故事，今天一个字都没有改变。
Citron’s short attack is sentiment, and Western Digital’s share sale is shareholder behavior — neither can change the fundamental reality of a structural shortage in NAND supply. The story that drove the stock from about $28 to about $725 has not changed by a single word today.
约23%的回调，发生在Q3指引数字没有变、毛利率扩张趋势没有变、NAND超级周期没有变的背景下。这是恐慌性情绪制造的折价窗口，不是基本面崩塌的警告。
This pullback of about 23% occurred against a backdrop in which the Q3 guidance figures have not changed, the gross margin expansion trend has not changed, and the NAND supercycle has not changed. This is a discounted window created by panic-driven sentiment, not a warning of fundamental collapse.
下半部分，我们会拆解Citron看空逻辑的具体反驳、NAND超级周期的供需结构分析，以及完整的分阶段建仓价位区间、三个阶段的止盈目标，和触发重新评估持仓的具体条件。
In the second half, we will break down the specific rebuttal to Citron’s short thesis, the supply-demand structure analysis of the NAND supercycle, as well as the complete staged entry price ranges, the three stages of profit-taking targets, and the specific conditions that would trigger a reassessment of the position.
