Why Sandisk Stock Skyrocketed 54.6% Last Month But Is Sinking in June
Sandisk jumped in May after a blowout fiscal Q3 report, but June has brought a pullback as AI-stock sentiment cools.
Intelligence analysis by GPT-5.4 Mini

Sandisk rallied sharply in May after reporting far better-than-expected fiscal Q3 results, helped by strong demand and upbeat AI-chip sentiment. In June, the stock has faded as semiconductor valuations cooled and stronger U.S. jobs data revived rate concerns.
Sandisk had a huge jump because it brought home a much better report than people expected. But in June, investors got more nervous about higher interest rates, which can make tech stocks wobble like a bike hitting a bump.
Analysis
May’s surge came from a huge earnings beat
Sandisk’s stock rose 54.6% in May after the company posted fiscal third-quarter results that landed far above Wall Street expectations. It reported adjusted earnings of $23.41 per share on revenue of $5.95 billion, compared with analyst estimates for $14.66 per share on $4.7 billion of sales. Revenue was up 251% year over year, and the article says margins looked strong in a favorable demand environment.
That earnings report arrived just as investor enthusiasm for AI-related chip stocks was running hot. The combination of a blockbuster print and a bullish sector backdrop helped drive several analyst price-target increases and pulled traders toward Sandisk’s memory-tech story.
June has been a different trade
The article says that bullish momentum for AI chips has cooled early in June. Broadcom’s quarterly report and guidance were met with a negative market reaction, even though its overall performance looked solid. At the same time, the May jobs report showed the U.S. added 172,000 nonfarm payrolls, well above economists’ expectations of 80,000.
That stronger labor-market reading made investors more concerned that the Federal Reserve could keep policy tighter for longer, or even raise rates this year. Higher rates are usually less friendly to tech stocks, including names like Sandisk. As a result, the stock was down 8% in June at the time of the article.
Key points
- Sandisk rose 54.6% in May after a much better-than-expected fiscal Q3 report.
- The company posted adjusted EPS of $23.41 on $5.95 billion in revenue, well above analyst estimates.
- Revenue increased 251% year over year, and margins were described as strong.
- June weakness is tied to softer AI-chip sentiment and worries about higher interest rates.
- A stronger-than-expected U.S. jobs report added to the market’s rate concerns.
If Sandisk keeps delivering results like its fiscal Q3 report, investors could keep rewarding the stock with higher expectations. Strong demand and a favorable position in memory technology could also help it stay a favorite when AI-related spending is strong.
If AI-chip sentiment keeps cooling, Sandisk could stay under pressure even after a strong quarter. Higher interest-rate expectations could also weigh on the stock if investors keep rotating away from tech.
