Price target: $800 represents approximately 47% upside from WDC's recent closing price around $545 and roughly coincides with its all-time high of $799.87 reached in June 2026. Strongest bullish factors: AI-driven hyperscale data center demand, tight nearline HDD supply, favorable pricing dynamics, and a robust technology roadmap featuring HAMR and 40TB UltraSMR drives.

Revenue reached $3.34 billion , surging 45% year-over-year and exceeding the consensus estimate of $3.25 billion. Non-GAAP diluted earnings per share (EPS) came in at $2.72 , beating analyst expectations of $2.39 by $0.33 and nearly doubling from $1.38 a year ago.

Revenue significantly exceeded expectations: Seagate posted fiscal Q4 2026 revenue of $3.63 billion, comfortably beating the FactSet consensus estimate of $3.5 billion and surging 49% year-over-year. Non-GAAP earnings per share (EPS) crushed estimates: Adjusted EPS came in at $5.71, well above the $5.10 analyst consensus and up 120% from $2.59 in the prior-year quarter.

DELL tumbled -14.55% during Tuesday's regular session, plunging from Monday's close of $426.91 to $364.79 as a global memory-chip rout spilled into AI infrastructure names. The selloff was triggered by Chinese DRAM maker ChangXin Memory Technologies' (CXMT) blockbuster Shanghai IPO, which surged +466% on debut and raised fears of aggressive Chinese capacity expansion disrupting global memory pricing.

SNDK fell -4.99% during Friday's regular session, sliding from a July 23 close of $1,610.33 to approximately $1,530.02 as of 9:49 AM ET, extending pre-market losses that began with a -2% to -3% overnight decline. The primary catalyst was a sharp sell-off in South Korean chip stocks — the KOSPI index plunged over 6%, while Samsung Electronics and SK Hynix each dropped more than 7%, triggering trading halts in Seoul and spilling contagion into U.S. memory names.

Seagate Technology shares dropped approximately 26.4% over the past 30 days, falling from $1,070.23 on June 18 to $787.66 on July 17, 2026. A broader AI memory and semiconductor sector rout — triggered by an SK Hynix HBM production report and a hawkish Federal Reserve repricing — fueled much of the decline.

Western Digital (WDC) shares tumbled approximately 36% over the past 30 days, falling from $746.23 (June 18 close) to $477.22 (July 17 close), as a sector-wide memory and storage rout erased a large portion of the stock's extraordinary year-to-date gains. The selloff was triggered by SK Hynix 's historic 15%+ single-day collapse in Seoul after a Korean brokerage cut Q2 2026 operating profit estimates roughly 8% below consensus, sparking cross-market contagion across U.S. memory and storage names.

WDC is down -4.71% in regular trading today, compounding yesterday's -8.78% plunge as a memory-sector rout deepens. The selloff is driven by aggressive profit-taking after memory stocks surged Tuesday on IBM's warning that customers were redirecting spending toward servers, storage, and memory chips.

SNDK plunged -14.33% during regular trading Wednesday, falling from a prior close of $1,757.82 to approximately $1,505.94 intraday, as a broad memory chip rout intensified. The sell-off was triggered by contagion from SK Hynix shares tumbling ~15% in South Korea following its record Nasdaq debut, dragging the entire memory sector lower.

DELL plunged -11.97% during regular morning trading, hitting a session low of $397.69 — its largest intraday drop since April 2025 — as a confluence of sector-wide AI fears and company-specific pressures triggered a sharp selloff. The primary catalyst: reports that Meta is planning to lease surplus AI training and inference capacity raised fears that hyperscalers may have over-built, threatening future AI server orders for system integrators like Dell.

Dell Technologies shares have surged over 230% year-to-date in 2026, propelled by explosive AI-optimized server demand and record quarterly results reported in late May. The company booked $24.4 billion in AI orders in its fiscal first quarter and exited with a $51.3 billion AI backlog, reinforcing its position as a leading AI infrastructure provider.

Shares of Western Digital Corporation (WDC) are indicated roughly 5% lower in premarket trading Monday, July 13, 2026, against Friday's close of $582.59. The decline extends a pattern of sharp pullbacks in memory and storage stocks tied to renewed profit-taking after an extraordinary year-to-date rally rather than any company-specific negative news.

Shares of Sandisk Corporation (SNDK) are indicated roughly 5% lower in premarket trading Monday, July 13, 2026, against Friday's close of $1,915.92, putting the stock near $1,820 ahead of the open. The primary driver is continued profit-taking across memory-chip stocks after an extraordinary year-to-date rally that has made SNDK the top-performing stock in the S&P 500.

Both STX and WDC have delivered exceptional year-to-date gains exceeding 200% amid surging demand for data storage solutions tied to artificial intelligence infrastructure. Seagate Technology focuses primarily on hard disk drives (HDDs) for nearline cloud and enterprise applications, while Western Digital maintains a diversified presence across HDDs and NAND flash memory through its joint venture.

HP Inc. shares declined approximately 10.3% over the past 30 days, falling from $25.58 to $22.96, as post-earnings optimism faded and memory-cost headwinds returned to the forefront.

IQMX fell -9.62% during regular trading on Tuesday, sliding to $11.65 from a prior close of $12.89, extending a two-day selloff after last week's post-SPAC debut surge. The decline occurred despite IQM announcing a major contract win with the LUMI AI Factory to deploy its Halocene H4 quantum computer, a deal whose value was already disclosed in the July 1 prospectus and largely priced in.

Super Micro Computer shares have fallen approximately 37% over the past 30 days, driven by a massive $7 billion equity financing announcement and an expanding regulatory probe in Taiwan. The company's June 9 capital raise plan, designed to fund a $39 billion AI server order backlog, triggered intense shareholder dilution fears that erased billions in market value within days.

SNDK is indicated roughly 5% lower in premarket trading against Tuesday's close of $1,744.43, putting shares near $1,657. The primary catalyst is a broad memory-chip selloff triggered by Samsung Electronics' preliminary second-quarter results, which failed to meet elevated AI-driven expectations despite posting solid headline numbers.

SNDK is down approximately -11.5% during Tuesday's regular session, extending a multi-session rout that has now erased over 25% from its all-time high near $2,354. The primary catalyst is a global memory chip selloff triggered by Samsung's blowout Q2 results — operating profit surged 1,810% YoY, but Samsung shares fell sharply in Seoul as investors executed a classic "sell the news" reaction.

Western Digital WDC shares fell 6.55% in premarket trading Tuesday, dropping to $539.66 from Monday's close of $577.46. The decline stems from a broad memory and storage sector selloff triggered by a "sell-the-news" reaction to Samsung's preliminary quarterly earnings.
