Memory sector stocks experienced a powerful rally Tuesday following enthusiastic commentary from Jim Cramer on the social platform X.
Cramer declared in one message: “Memory shortage stocks have to go to a higher place. It’s very difficult to imagine it, but stocks do gallop to where they should be… WDC SNDK, STX, will be overheated until they get to where they have to go.”
He reinforced his stance in a subsequent post, labeling Oracle and SanDisk as “the tells of this market.”
SanDisk stock climbed 9.64% during Tuesday’s trading session. The shares have skyrocketed 480% since the beginning of the year and have posted staggering gains exceeding 3,600% over the trailing 12-month period.
Cramer emphasized that SanDisk is capitalizing on constrained supply dynamics in the memory sector. “Look I was on that Seagate call, they’re not even spending that much money, they’re enjoying the tightness. Sandisk is enjoying the tightness,” he stated.
This supply constraint extends across consumer, enterprise, and hyperscale segments — creating widespread pressure that’s driving pricing power throughout the industry.
Analyst Upgrades Preceded the Rally
Cramer’s remarks followed recent bullish revisions from prominent Wall Street firms regarding SNDK.
Cantor Fitzgerald boosted its price objective to $1,400 from $1,000 on April 27, reaffirming an Overweight stance. The firm anticipated SanDisk would exceed expectations and raise guidance in its upcoming quarterly report.
Morgan Stanley similarly increased its target price that day, raising it to $1,100 from $690 while keeping its Overweight rating intact. The investment bank cited ongoing maximum AI infrastructure investment as a tailwind for the company.
Both analyst teams highlighted constrained NAND manufacturing capacity as a fundamental catalyst supporting SanDisk’s momentum.
Memory Sector Experiences Broad-Based Strength
SNDK’s advance wasn’t an isolated event. Several memory and storage stocks experienced significant gains alongside it.
Western Digital (WDC) advanced 5.34% Tuesday, adding to its impressive 170% year-to-date performance. Seagate (STX) gained 4.87%, continuing its strong 181% run so far this year. STX has surged over 686% in the past year.
Oracle (ORCL), which Cramer also highlighted, edged up 1.16% during the session, although it remains down 5.85% year-to-date. The stock has appreciated 22% over the past 12 months.
Micron (MU) emerged as another major winner, despite not receiving direct mention from Cramer. MU soared 12.09% Tuesday, reaching a new all-time high. The stock has advanced 126% year-to-date and has climbed 616% over the trailing year.
The synchronized rally across these companies demonstrates robust investor demand for memory and storage investments as AI infrastructure expenditures remain at elevated levels.
With its 480% year-to-date advance, SanDisk ranks among the top-performing stocks in the market during 2026.
