Sandisk Corporation (SNDK) drops on memory stock selloff
Sandisk Corporation (SNDK) drops as investors rotate out of high-flying memory stocks after SK Hynix flagged a sharp increase in capital spending. The move appears driven by sector-wide oversupply fears rather than a company-specific earnings miss, even though Sandisk’s recent results remain strong.
Sandisk Corporation (SNDK) dropped 6.2% as investors sold memory stocks on renewed fears of future oversupply after SK Hynix announced a 50% jump in capital spending. The decline was not tied to a Sandisk-specific earnings warning, but it does show how quickly sentiment can reverse in a crowded, highly cyclical trade. For investors, the key issue is whether NAND pricing and AI storage demand can stay strong enough to justify Sandisk’s premium valuation.
Sandisk Corporation (SNDK) Drops as Memory Stocks Sell Off
Sandisk Corporation (SNDK) drops sharply as investors reduce exposure to high-flying memory stocks. At 11:04 ET on July 29, shares traded at $1,027.64, down 6.25%, after opening at $1,121.67. The clearest catalyst is a sector shock tied to SK Hynix's capital-spending plans, not a new Sandisk-specific earnings report or analyst downgrade.
Key Takeaways
SNDK traded at $1,027.64 at 11:04 ET, down 6.25% for the session.
SK Hynix said its capital spending will rise 50% to at least $31B, reviving fears of future memory oversupply.
Sandisk's latest reported EPS was $23.41, well above the $14.66 estimate, but its P/E remains elevated at 43.67.
The long-term story still depends on NAND pricing, AI storage demand, and supply discipline.
Investors should separate strong recent earnings from the risks of a crowded, highly cyclical trade.
What's Behind Sandisk Corporation's Selloff Today
The most important event arrived from the broader memory industry. SK Hynix said capital expenditures will surge 50% this year to at least $31B. Its shares then fell 34% below their post-IPO high. That reaction shows how quickly investors can turn from celebrating AI demand to fearing a future supply glut.
Another July 29 headline reported that SK Hynix delivered a 557% profit surge to $42B but still missed estimates. In a cyclical industry, record earnings do not always protect a stock. Markets price the next supply and pricing cycle, often with the patience of a caffeinated day trader.
That logic reaches Sandisk because SNDK acts as a high-beta NAND proxy. Investors have recently traded Sandisk and Micron Technology (MU) together during technology selloffs. The July 29 headlines also described Sandisk as a major loser after a steep first-half rally.
There was no fresh Sandisk-specific announcement in the immediate 24-hour window. The most recent dated company event was a July 9 investor-relations announcement that Sandisk will report fiscal fourth-quarter and fiscal-year 2026 results on August 5. The company also scheduled an Investor Day for August 13. Those dates matter, but they do not explain the sudden July 29 decline as directly as the SK Hynix shock does.

Why SNDK's Trading Activity and Price Swings Matter
The raw trading activity was substantial. A live intraday snapshot recorded 8,332,489 SNDK shares traded, while another quote showed relative volume at 0.7 times the 200-day average. Therefore, the tape confirms active trading, but it does not support a firm claim that volume is above its long-term average.
The price action itself is extreme. The intraday range ran from $1,004.15 to $1,124.39 in one session. SNDK also entered the day after an extraordinary first-half run. Sandisk gained 858% through June 30, according to a July 29 report, while Micron gained 304% over the same period.
Such gains create a fragile setup. Profit-taking does not require a broken business. It only requires a crowded trade and a new reason to question the next six months. SNDK mentions rose 487% in a 12-hour window on July 27, and recent discussion focused on extreme price targets and whether the stock had become overextended.
News sentiment remained strongly positive, with a seven-day score of 0.8268 and a 30-day score of 0.8109. That contrast is useful. The selloff looks more like a reset in positioning and sector risk than a broad collapse in published sentiment.
How Sandisk Corporation's Financials Look After the Drop
Sandisk's recent earnings provide real support for the bullish case. On April 30, the company reported EPS of $23.41 against an estimate of $14.66. That produced a 59.7% upside surprise. The earnings history also records six beats in six comparable reported quarters.
The earnings trend accelerated sharply. EPS was $0.29 in August 2025, $6.20 in January 2026, and $23.41 in April 2026. The current fundamentals snapshot lists EPS at $25.10. These figures show why investors assigned Sandisk a premium valuation.
However, the valuation leaves little room for a softer cycle. Sandisk's market capitalization stood at $152.18B, and its P/E was 43.67. That multiple can work when NAND prices rise and demand expands. It can also magnify a selloff when investors fear that new capacity will weaken pricing.
Analyst targets show how divided the valuation debate has become. The consensus target was $1,992.67, with a high of $3,100 and a low of $650. Recent actions included Wells Fargo raising its target to $1,620 from $1,250 on July 22. Susquehanna then lowered its target to $3,050 from $3,250 on July 23. Those changes do not establish a unified bearish view, but they do show wide expectations.
Sandisk's NAND Outlook and the Investor Decision
Sandisk develops NAND flash products for several markets. Its portfolio includes solid-state drives for PCs, gaming consoles, and set-top boxes. It also sells embedded storage for phones, tablets, vehicles, industrial equipment, and connected devices.
That product breadth supports Sandisk's competitive position, but it does not remove the memory cycle. NAND remains a pricing-sensitive hardware market. Supply growth, inventory levels, and contract pricing can change earnings faster than product headlines can change.
The demand case still has force. A July report citing UBS projected NAND pricing growth of 30% quarter over quarter in the third quarter of 2026 and 12% in the fourth quarter. AI systems require more storage, while supply discipline has helped the memory recovery. Yet SK Hynix's 50% capital-spending increase shows how quickly supply risk can challenge that thesis.
A disciplined investor can use three practical tests. First, compare the August 5 EPS result with the $23.41 reported on April 30. Second, judge the 43.67 P/E against the durability of NAND pricing rather than against the day's panic. Third, treat the $650 to $3,100 analyst target range as evidence of uncertainty, not as a guaranteed return.
SNDK can remain attractive for investors who accept memory-cycle risk and believe AI storage demand will outpace new supply. Position sizing matters more after an 858% first-half gain. A lower price alone does not create value, but a sharp reset can improve the entry point if earnings and NAND pricing continue to support the business.
Sandisk's July 29 decline is best explained by a memory-sector repricing after SK Hynix announced a 50% increase in capital spending and investors revived oversupply fears. Strong EPS results support the company, but a 43.67 P/E and extreme recent gains leave SNDK vulnerable to fast profit-taking.
The investment case now rests on execution, NAND pricing, and supply discipline. The August 5 earnings date and August 13 Investor Day provide the next scheduled company events, while the current selloff tests whether Sandisk is a durable storage leader or simply the market's latest crowded memory trade.
SNDK is down because the broader memory sector sold off after SK Hynix said it will sharply increase capital spending, raising oversupply concerns. The move appears to be sector-driven rather than caused by a new Sandisk-specific negative announcement.
+Should I buy SNDK stock now?
Only if you are comfortable with high volatility and memory-cycle risk. Sandisk still has strong earnings momentum, but the stock’s premium valuation means a further pullback is possible if NAND pricing weakens.
+Did Sandisk miss earnings?
No. The article says Sandisk’s latest reported EPS beat estimates by a wide margin, so today’s decline is not being driven by an earnings miss. Instead, investors are reacting to sector-wide supply concerns.
+What does SK Hynix have to do with SNDK?
SK Hynix’s higher capital-spending plans revived fears that more memory supply could pressure future pricing. Because Sandisk is viewed as a high-beta NAND stock, traders often sell it alongside other memory names when those concerns rise.
