Key Takeaways
- SK Hynix’s American Depositary Receipt declined 5% on Wednesday following Tuesday’s remarkable 27% jump as investors secured profits
- Shares of Micron, SanDisk, and Western Digital tumbled between 3% and 6%, while the Roundhill Memory ETF retreated 3%
- The launch of four new leveraged SK Hynix ETFs this week has increased intraday price swings

- Wall Street analysts maintain predominantly bullish stances on Seagate, Western Digital, and SanDisk despite Wednesday’s retreat
Memory semiconductor stocks experienced significant declines Wednesday as investors capitalized on profits after witnessing one of 2026’s most impressive semiconductor sector rallies.
SK Hynix’s U.S. ADR tumbled 5% to close at $184.50, a sharp reversal from Tuesday’s explosive 27% surge to $193.92. Market observers noted the correction wasn’t surprising considering the stock’s recent parabolic ascent.
The selling pressure wasn’t isolated to SK Hynix. Micron shares retreated 3% to $953, while SanDisk plummeted 6% to $1,658, and Western Digital decreased 4% to $541. The Roundhill Memory ETF posted a 3% decline, settling at $59.
Correction Follows Extraordinary Gains
Wednesday’s retreat occurred after exceptional year-to-date performance across the memory sector. Micron has skyrocketed 244% since January. Through Tuesday’s session, SanDisk had delivered an astounding 640% gain. Notably, no negative company-specific developments triggered Wednesday’s selloff — the movement appeared to be classic profit-taking behavior.
Micron’s latest quarterly results revealed revenue reaching $41.46 billion, representing a staggering 346% year-over-year increase, accompanied by forward guidance projecting $50 billion for the upcoming quarter. SanDisk’s datacenter segment posted revenue growth of 645% year-over-year, totaling $1.47 billion.
SanDisk’s financial performance has been exceptional, featuring a gross margin of 78.4%, adjusted free cash flow approaching $3 billion, and the completion of multiple multi-year agreements valued in the tens of billions. Company leadership provided guidance calling for revenue between $7.75 billion and $8.25 billion next quarter, with gross margins potentially expanding to 81%.
Seagate delivered impressive quarterly results as well, reporting revenue climbing 44% year-over-year to $3.1 billion alongside a non-GAAP gross margin of 47%. The company exceeded earnings per share projections by 59 cents. Seagate shares have nearly tripled since the beginning of the year, with Wall Street’s consensus price target hovering around $899.
Western Digital achieved 45% year-over-year revenue growth, reaching $3.3 billion, while nearly doubling EPS and reducing debt by more than $3 billion. The company executed $752 million in stock buybacks during the most recent quarter and announced a dividend increase. Market watchers are closely monitoring its July 29 earnings announcement.
New Leveraged Products and Chinese Rivals Complicate Outlook
This week marked the debut of four leveraged single-stock ETFs tracking SK Hynix, with two offerings from Direxion and two from GraniteShares. These products reset daily and magnify intraday price movements while carrying substantial risk, including the possibility of complete principal loss within a single trading session.
Barron’s recently highlighted increasing competition from Chinese memory chip manufacturers as a potential long-term challenge. ChangXin Memory Technologies is moving toward an IPO that industry observers believe could significantly alter competitive dynamics.
Notwithstanding Wednesday’s pullback, Wall Street sentiment remains overwhelmingly positive. SanDisk enjoys 21 Buy ratings alongside five Hold recommendations. Western Digital counts 20 of 24 analysts rating it a Buy. Seagate has garnered Buy ratings from 22 of 27 analysts covering the stock.
The memory sector’s next significant catalyst arrives with Western Digital’s earnings report scheduled for July 29, which market participants expect will provide direction for the group through the year’s second half.
