SanDisk stock moved dramatically amid strength in the storage-device sector.
The climb to the peak looks like a strong rally when viewed alone, but the subsequent decline of roughly half must also be considered.
Changes in holdings by U.S. institutional investors also showed a clear split rather than unified conviction in the same direction.
3-Line Summary
1. SanDisk fell about 50% after its surge
2. Second-quarter holding changes split between buying and selling
3. The company’s targets and actual results must be distinguished
From 235 Dollars to 2,354 Dollars (2354), Then Back to 1,119 Dollars (1119)
SanDisk is a storage-related stock traded as SNDK on the U.S. stock market. Yahoo股市 reported that its stock price, which was about 235 dollars at the beginning of 2026, rose to a 52-week high of 2,354 dollars (2354), representing a 628% increase from the start of the year. It was described as an unusually large gain even among memory stocks.
However, the stock quickly reversed after reaching its high. The same report said it fell about 50% from the peak, at one point dropping to about 1,119 dollars (1119), before rebounding to around 1,741 dollars (1741). Looking at the starting point, high, and low together, the key point is not a single rate of increase, but that both the rise and the decline were substantial.
富聯網 reported that SanDisk closed at 1,786.85 dollars (1786.85), up 145.74 dollars (145.74), or 8.88%, during a Monday U.S. regular session. This was described as the highest closing price since July 10, and trading value was 309억2,700만달러. It also reported that the stock had risen 35% that week alone.
The rise that day was not unique to SanDisk. The same report said Micron in the United States rose 4.13%, Western Digital rose 5.35%, Seagate rose 2.19%, and SK hynix American depositary shares rose 3.04%. However, five storage-related stocks were also described as having plunged broadly by 30~40% at one point in July. Even if there was a short-term rebound, that does not mean the preceding decline disappeared.
The Holder That Increased to 20만8천 Shares and the One That Kept Only 4,980 Shares
Changes in holdings reported to the U.S. Securities and Exchange Commission (SEC) through mid-August in second-quarter 13F filings showed that hedge funds’ choices were sharply divided. Yahoo股市 reported that some funds increased their positions in anticipation of storage demand from artificial-intelligence (AI) servers, data centers, and high-performance computing, while others chose to take profits or withdraw.
Discovery Capital newly purchased about 18만4천 shares, and the investment amount exceeded 100 million dollars, according to the report. Its second-quarter holdings then increased to about 20만8천 shares. At the time of the first-quarter purchase, this was reportedly one of the fund’s largest buying transactions.
Locus Capital also increased its holdings from about 5만7,063 shares to 7만2,771 shares, an increase of 28%. The fund, however, had previously reduced its holdings from about 7만9,398 shares to 5만7,063 shares in the first quarter. The second-quarter increase is better understood as a decision to raise its position again after an earlier reduction than as a simple continuation of buying.
On the other side, Duquesne made a modest reduction from about 3만8천 shares to about 3만5천 shares. Appaloosa reportedly sold all of the approximately 28만 shares it had accumulated in the first quarter during the second quarter. Renaissance Technologies reduced its holdings from approximately 79만9,600 shares to 4,980 shares, a reduction of more than 99%. Because the fund had already reduced its holdings from about 120만 shares to 79만9,600 shares, or 34%, in the first quarter, it continued reducing its position across two quarters.
The Position of the 15% Growth Target and the 939억-Dollar Contract
The mid- to long-term direction presented by SanDisk also needs to be viewed separately from the stock’s movements. 富聯網 reported that, at its investor day, the company presented a target of approximately 15% average annual growth in mid- to long-term revenue. It also mentioned a direction aimed at mitigating the large cyclical swings of the traditional memory industry through long-term customer contracts, supply discipline, and shareholder returns.
Cnyes reported that SanDisk set a mid-to-high single-digit? No, it reported a mid-to-high double-digit revenue-growth target and announced a plan to return 100% of excess cash to shareholders. It also reported that the company had entered into a 93.9 billion-dollar long-term contract (939억달러), and that the HBF sample program was planned for 2027. These were targets, plans, and contract details presented at the time of the reports; they do not mean that the target revenue growth or shareholder returns had already been achieved.
Expanded AI investment and the outlook for memory supply and demand were cited as reasons for the rise. However, 富聯網 pointed out that the rebound also reflected a pullback after the sharp decline, in addition to improved expectations. The most important point when reading SanDisk’s stock price is neither one-sided optimism nor selling alone. During the same surge, funds split between adding to their positions and almost completely exiting, while the company’s long-term targets also remain promises yet to be achieved.
