Sandisk Corporation (SNDK) drops 6.4% after huge rally
May 18, 20266 min read
Key Takeaway
Sandisk Corporation (SNDK) dropped 6.4% today as traders locked in gains after a powerful post-earnings run, not because of a new earnings miss or business warning. The selloff reflects profit-taking and momentum unwinding in a stock that had already been rerated sharply on strong results, raised price targets, and upbeat guidance. For investors, the move suggests the company’s fundamentals remain intact, but the shares are now more vulnerable to volatility after a steep rally.
Sandisk Corporation (SNDK) drops 6.42% today to $1,317.265 as of 12:05 p.m. ET, a sharp reversal for one of the market’s hottest AI and memory names. The move matters because it follows a huge post-earnings rerating, which leaves the stock more exposed to profit-taking when fresh company-specific news is thin.
Key Takeaways
•
SNDK is down 6.42% intraday, extending a volatile stretch after its powerful rally following fiscal Q3 2026 results.
•
The most likely driver is profit-taking and momentum unwinding, not a new earnings miss, downgrade, or business setback announced today.
•
The company’s latest fundamentals remain strong: fiscal Q3 revenue reached $5.95B, diluted EPS was $23.03, and reported EPS of $23.41 beat the $14.66 estimate by 59.7%.
•
Sandisk also guided fiscal Q4 revenue to $7.75B to $8.25B and non-GAAP EPS to $30 to $33, while authorizing a $6B buyback.
•
For investors, today’s selloff looks more like a reset in an extended stock than a clear break in the company’s operating story.
What’s Behind Sandisk Corporation’s Selloff Today
The cleanest explanation for today’s decline is that SNDK is giving back part of an enormous earnings-driven run. In the last 24 to 48 hours, there was no fresh earnings release, major contract, merger announcement, or analyst downgrade tied to today’s move. Instead, the stock entered the session after a massive revaluation in late April and early May, which set up a classic momentum reversal.
That setup matters. Sandisk had already surged on the back of fiscal Q3 2026 results and a wave of target increases from Wall Street. On May 1 alone, firms including Goldman Sachs, Mizuho, Evercore ISI, Raymond James, Susquehanna, Barclays, Jefferies, and Wedbush raised price targets. Bernstein followed on May 4 with a $1,700 target, and Mizuho raised its target again to $1,625 on May 6. When a stock runs that hard, it does not need bad news to fall. It just needs buyers to pause.
There is also a technical feel to the tape. Reports showed SNDK opened at $1,430.55, traded as high as $1,449.35, and then reversed lower. That kind of intraday pattern often lines up with traders taking gains after early strength. In plain English, the stock climbed a very steep hill, and today some fast money chose to walk back down.
A minor headline may have added friction. On May 14, Sandisk warned shareholders to reject an unsolicited mini-tender offer from Tutanota LLC for up to 100,000 shares at $1,150 each. That is not a core business problem, but it is the sort of side headline that can feed caution when a stock is already stretched.
Sandisk Earnings Strength Still Anchors the Story
Importantly, the company’s recent operating numbers still look powerful. Sandisk reported fiscal Q3 2026 revenue of $5.95B, GAAP net income of $3.615B, and diluted net income per share of $23.03. Separately, earnings history shows EPS of $23.41 versus a $14.66 estimate, a 59.7% surprise. That is not a soft quarter. It is the kind of print that forces the market to rethink what the business can earn in an upcycle.
The forward guide was even more striking. Sandisk projected fiscal Q4 revenue of $7.75B to $8.25B and non-GAAP EPS of $30 to $33. Those figures explain why the stock had been rerated so aggressively before today’s drop. The market was not paying up for hope alone. It was paying up for a sharp jump in earnings power tied to stronger NAND pricing, tighter supply, and heavier demand from datacenter and AI infrastructure customers.
The earnings track record backs that up. Sandisk has beaten EPS estimates in six straight reported quarters. Recent surprises were not small either: 75.1% in January 2026, 37.1% in November 2025, and 866.7% in August 2025. That pattern tells a simple story. The business has been improving faster than analysts expected, and the stock had priced in a lot of that improvement before today’s setback.
How Sandisk Corporation’s Valuation and Balance Sheet Look After the Drop
Even after a 6.42% decline, SNDK is not a cheap stock on a headline basis. The shares trade at a P/E of 48.07, and the market cap stands at $195.07B. That valuation can work when earnings are exploding higher, but it also leaves little room for sloppy execution or a cooling memory cycle. In other words, the company can be strong while the stock still gets hit for being crowded and expensive.
At the same time, the balance sheet has improved in a meaningful way. On May 12, S&P Global Ratings upgraded Sandisk to BB+ and cited strong demand, deleveraging, and a net cash position after the company repaid all debt. S&P also pointed to the $6B share repurchase program. For a memory company, that is a serious upgrade in financial flexibility. Cyclical businesses usually get punished when leverage is high. Sandisk is moving in the opposite direction.
That combination creates an interesting split. Fundamentally, the company looks healthier than it did a year ago. Valuation-wise, however, the stock already reflects a lot of good news. That tension helps explain why a bullish fundamental backdrop can still produce a rough trading day.
AI Memory Demand and Analyst Support Still Shape the Forward Outlook
Sandisk’s competitive position is tied to NAND flash and storage products sold into PCs, mobile devices, automotive, industrial markets, and, most importantly right now, datacenter workloads. Recent commentary around the stock has centered on AI inference demand, memory shortages, and tighter pricing. Those are the forces that turned Sandisk from a cyclical hardware name into a market favorite.
Analyst sentiment still leans supportive. The consensus rating is Buy, with 12 buys and 3 holds. The consensus price target is $1,268, with a high target of $2,000. That is notable because the stock is already trading above the consensus target even after today’s decline. So the market has moved faster than the average analyst model, which is another sign that some air can come out of the shares without changing the core thesis.
News sentiment has also been strong. The quantified 7-day sentiment score sits at 0.8857, with the trend marked as improving. Usually, a stock selling off against that backdrop points to positioning and expectations, not a sudden collapse in narrative. Said differently, the business story still has fuel, but the stock had become a very full trade.
Actionable insight starts with separating company health from stock behavior. Sandisk still has strong earnings momentum, a net cash position, a $6B buyback, and heavy exposure to AI-linked memory demand. However, with the shares near the upper end of Wall Street targets and trading at 48.07 times earnings, pullbacks like this are part of the price of owning a momentum leader.
Sandisk Corporation’s drop today looks driven more by profit-taking after an extreme run than by a new fundamental crack in the story. The numbers that fueled the rally remain impressive, but the stock had become rich enough that even a quiet news day could trigger a hard reset.
SNDK is falling mainly because investors are taking profits after a huge earnings-driven rally. There is no fresh company-specific negative news today, so the move looks like a momentum reset rather than a fundamental breakdown.
+Should I buy SNDK stock now?
The article suggests caution, because the stock still looks expensive and has already run far ahead of consensus targets. Long-term fundamentals remain strong, but today’s drop does not by itself make the shares cheap.
+Did Sandisk miss earnings or lower guidance?
No. Sandisk’s recent results were strong, with revenue and EPS beating expectations, and the company also issued upbeat forward guidance. Today’s decline is not tied to a new earnings disappointment.
+Is this SNDK selloff a sign the business is weakening?
Not based on the information in the article. The business story remains strong, and the stock’s decline appears to be driven by valuation, positioning, and profit-taking after a sharp rally.
