Key Takeaways
- Seagate (STX) stock dropped 7.1% during a widespread selloff affecting memory and storage companies following reports of SK Hynix scaling back HBM production
- South Korea’s benchmark KOSPI index plummeted 10%, triggering a trading halt, while SK Hynix and Samsung each declined over 10%
- Hawkish Federal Reserve positioning under Chair Kevin Warsh increased expectations for additional 2026 rate increases to approximately 85%
- Fox Advisors reduced Seagate’s rating to Equal-Weight following the stock’s climb to record highs
- Wedbush analysts view the decline as an attractive entry point, citing solid enterprise demand fundamentals
Shares of Seagate Technology (STX) were changing hands at $958.94 heading into Tuesday’s trading before falling 7.1%, caught in a broader downdraft sweeping through memory and storage equities. This marked the second consecutive session of losses, following a 6% retreat the previous day, reversing some of the stock’s impressive gains.

The catalyst behind the slide emerged from South Korean media outlets reporting that SK Hynix might be decelerating its high-bandwidth memory (HBM) expansion plans while redirecting manufacturing resources toward traditional DRAM production. Despite SK Hynix refusing to provide official commentary, markets responded with immediate selling pressure.
The fallout was dramatic. South Korea’s KOSPI index, which had climbed approximately 95% year-to-date, crashed 10% before circuit breakers kicked in. Shares of both SK Hynix and Samsung experienced double-digit percentage losses during the session.
Most market observers interpret this development as driven by profitability considerations rather than weakening demand. Traditional DRAM supply constraints have elevated operating margins beyond HBM production levels, with Korean market experts estimating the profitability difference exceeds 15 percentage points. Samsung recently disclosed a 146% increase in DRAM average selling prices for Q1, while SK Hynix reported gains in the mid-60% range.
However, HBM serves as the critical memory component in Nvidia’s artificial intelligence accelerators. Any news hinting at reduced HBM production naturally sparks concerns about potential cooling in AI infrastructure investment—and that knee-jerk reaction dragged Seagate significantly lower.
Federal Reserve Stance Intensifies Concerns
Adding to sector-wide weakness was a more aggressive interpretation of Federal Reserve policy direction. With Kevin Warsh now leading as Chair, market expectations for a second rate increase in 2026 climbed to roughly 85%, up from approximately 60%. When traders anticipate 50 basis points worth of tightening by year-end, financing AI capital expenditures through debt becomes less attractive at present market valuations.
The divergence in selling intensity revealed the market’s focus: memory-centric stocks absorbed the heaviest punishment. Micron experienced an approximate 11% decline, while chip design leader Nvidia dropped a comparatively modest 3.6%.
Fox Advisors contributed to the downward pressure by lowering Seagate to Equal-Weight, pointing to overbought technical conditions following the stock’s ascent to all-time peaks. This timing amplified volatility during an already turbulent trading day.
Wedbush analysts countered the pessimistic sentiment, characterizing the pullback as an opportune moment for accumulation given what they describe as robust enterprise demand conditions.
Perspective on Recent Performance
Prior to Tuesday’s decline, Seagate had rallied 233% year-to-date, establishing a fresh 52-week peak at $958.94. As a comparison point, Micron had appreciated roughly 300% from the beginning of the year before Tuesday’s trading session.
The equity has experienced 49 single-day movements exceeding 5% during the past twelve months, indicating Tuesday’s swing was significant yet consistent with the stock’s historical volatility patterns.
An investment of $1,000 in Seagate five years ago would have grown to approximately $11,100 at current levels.
Market participants awaited Micron’s quarterly earnings release scheduled for after Tuesday’s closing bell, with the entire memory sector anxiously anticipating management commentary regarding AI-driven data center demand trends.
