Seagate Technology Holdings plc (NASDAQ: STX) is finishing 2025 in full sprint.
As of Thursday’s session, the data‑storage giant is trading around $298.92, up roughly 5–6% on the day and hovering just below its recent all‑time high near $301.47. The stock’s 12‑month low sits at $63.19, underscoring the magnitude of the move. [1]
Different data providers now peg year‑to‑date gains above 200%: Barchart estimates roughly +246% YTD and +206% over the past 52 weeks, while Smartkarma cites about +228% YTD, compared with roughly +20–23% returns for the Nasdaq Composite over similar periods. [2]
That kind of outperformance is why Seagate has suddenly gone from “old‑school disk drive name” to “AI infrastructure winner” in many investors’ eyes.
Today’s move: STX trades like an AI high‑flyer
MarketBeat’s latest institutional‑activity note reports Seagate trading up about 5.7% on Thursday, opening at $298.92 with a market cap near $64 billion, a trailing P/E around 38x, PEG ratio around 1.1, and beta of roughly 1.6. [3]
Technically, Barchart notes that STX has traded above its 50‑day moving average since late April and above its 200‑day since early May, a textbook bullish trend profile. [4]
Barchart’s deep‑dive on Thursday points out:
- STX recently touched an all‑time high around $301.47 before a modest pullback.
- Over the last three months, the stock is up around 55%, far ahead of the Nasdaq’s single‑digit gain.
- Year‑to‑date and one‑year performance both exceed +200%, making Seagate one of 2025’s standout tech names. [5]
In other words, STX is trading like an AI momentum stock, not like a slow‑growing hardware supplier.
Why Seagate is suddenly hot: AI, HAMR and 30TB drives
The core of the bull story is straightforward: AI needs absurd amounts of data storage, and Seagate is selling the equivalent of industrial‑scale hard‑drive concrete to build that foundation.
A few key developments in 2025 re‑wired the narrative:
- HAMR and Mozaic 3+ platform
Seagate has spent years pushing Heat‑Assisted Magnetic Recording (HAMR) into production. Its Mozaic 3+ platform allows far higher areal density than conventional hard drives, meaning more terabytes per drive at competitive cost. [6] - 30TB Exos M and IronWolf Pro go mainstream
In July, Seagate announced global availability of 30TB Exos M and IronWolf Pro HDDs, built on Mozaic 3+ and powered by HAMR. These are aimed squarely at AI‑heavy data centers and high‑capacity NAS deployments, where cheap, dense storage is critical. [7] - Over one million HAMR drives shipped & deep cloud adoption
By the October quarter, Seagate disclosed it had shipped more than one million Mozaic HAMR drives and had those products qualified with five of the world’s largest cloud providers, with more customers in the pipeline. [8]
A detailed AI‑themed analysis from Blocks & Files stresses that Seagate’s data‑center revenue jumped 34% year‑on‑year to about $2.1 billion, representing roughly 80% of total revenue, as capacity‑constrained cloud buyers locked in nearline HDD supply through 2026 via build‑to‑order contracts. [9]
Meanwhile, a Nasdaq piece on Seagate’s outlook frames AI as a structural tailwind: the firm argues that large‑capacity HDDs remain essential to store the torrents of unstructured data generated by AI workloads, from video analytics to inference logs. Seagate itself highlights that a single minute of AI‑generated video can be orders of magnitude larger than a text file, requiring ever‑larger and cheaper storage pools. [10]
Taken together, 2025 turned Seagate from “PC drive vendor” into a core infrastructure supplier to AI data centers and sovereign clouds.
Earnings: record margins, booming free cash flow, bullish guidance
Seagate’s fiscal Q1 2026 results (reported October 28, 2025) put hard numbers behind the story:
- Revenue: $2.63 billion, up about 21% year‑on‑year
- GAAP gross margin:39.4%, with non‑GAAP at 40.1% – both record levels
- GAAP diluted EPS:$2.43
- Non‑GAAP diluted EPS:$2.61
- Operating margin: mid‑ to high‑20% range on both GAAP and non‑GAAP basis
- Operating cash flow:$532 million
- Free cash flow:$427 million
- Capital return: $182 million via dividends and share repurchases
- Dividend: quarterly payout raised ~3% to $0.74 per share [11]
For fiscal Q2 2026, Seagate guided to:
- Revenue: about $2.7 billion ± $100 million
- Non‑GAAP EPS: about $2.75 ± $0.20 [12]
Blocks & Files notes that AI inferencing is driving higher‑capacity nearline adoption: average nearline drive capacity rose 26% year‑on‑year, and Seagate expects current Mozaic 3+ drives and upcoming Mozaic 4+ platforms to push capacities toward 44TB and beyond. [13]
That combination—double‑digit revenue growth, record margins, strong free cash flow and visible demand through 2026—forms the backbone of the bullish investment case.
How Seagate became an “unlikely AI winner” in 2025
A widely circulated Stocktwits analysis grouped Seagate and Western Digital as “the best AI trades of the year”, noting that both delivered gains north of 200% in 2025 after a deep industry downturn in 2023–24. [14]
Key points from that piece:
- The AI compute boom dramatically accelerated demand for mass‑capacity storage.
- Seagate has a technology lead in HAMR and has secured multi‑year visibility with cloud customers, with nearline capacity largely committed through calendar 2026 and longer‑term deals extending into 2027. [15]
- Analysts highlighted that the HDD industry’s newfound supply discipline and higher AI‑driven pricing power are lifting margins across the board.
At the same time, the article flagged that storage remains a cyclical industry, and that expectations for AI‑related spending are extremely high; a slowdown in AI capex could trigger sharp downside in the group. [16]
That tension—between structural AI demand and classic hardware cyclicality—is now central to how investors frame Seagate.
What Wall Street is saying: strong ratings, mixed price targets
Across major data providers, Seagate screens as broadly liked but not obviously cheap at current levels.
- MarketBeat aggregates 26 analyst ratings and assigns Seagate a “Moderate Buy” consensus:
- 1 Sell
- 5 Hold
- 20 Buy/Strong Buy combined
The average 12‑month price target sits around $287, implying a small downside of roughly 2% from a price in the high‑$280s/low‑$290s when their snapshot was taken. [17]
- StockAnalysis shows a “Buy” consensus from 22 analysts with an average target near $254, which would be low‑teens downside from the current ~$299 level. [18]
- TickerNerd compiles 37 analyst views and finds a bullish consensus with a median price target of $270, again implying mid‑single‑digit downside from current prices, and a target range between $150 and $465. [19]
- Fintel / Nasdaq cite an average one‑year target around $283, representing mid‑single‑digit upside from earlier trading levels; that dataset also implies double‑digit revenue growth and non‑GAAP EPS above $13 on a forward basis. [20]
Individual broker calls have been increasingly aggressive:
- Citigroup recently raised its STX target from $275 to $320 and reiterated a Buy rating, citing Seagate as a key AI storage beneficiary. [21]
- China Renaissance initiated coverage with a Buy and a $325 target, while Fintel’s summary of their data shows average targets near $283 with highs close to $488. [22]
- The Barchart piece notes that among 24 analysts tracked there, STX carries a “Strong Buy” label and trades slightly above its mean price target of about $294. [23]
In short: ratings are strongly positive, but price targets are clustered around or slightly below today’s price, suggesting that much of the near‑term optimism is already reflected in the stock.
Quant, sentiment and smart‑money signals
A flurry of quantitative and sentiment‑driven research has landed in December:
- Smartkarma highlighted Thursday that STX was trading around $298.92, up 5.68% on heavy volume, with an eye‑catching YTD gain of roughly 228%. Its internal “Smart Score” framework assigns Seagate strong marks for dividend, growth, resilience and momentum, but a weak score on value, resulting in an overall composite of 3.4/5. [24]
- StockTradersDaily published an AI‑driven technical note on December 7, describing:
- “Weak” near‑term sentiment (1–5 days),
- “Neutral” medium‑term, and
- “Strong” long‑term trend signals.
Their models flag resistance around the high‑$270s to low‑$280s and outline a short‑term risk‑hedging short setup with roughly 16% potential downside vs about 0.3% risk, while still presenting long‑bias setups for position traders. [25]
- Options & fund flows
Fintel’s breakdown of options positioning shows a put/call ratio around 1.17–1.19, suggesting more puts than calls outstanding and hinting that some investors are hedging or betting on a pullback despite the bullish fundamental story. At the same time, they report more than 1,700 institutional investors holding STX, with average portfolio weights in the 0.3% range and high overall institutional ownership. [26] - Hedge funds & long‑only managers
A fresh MarketBeat filing summary notes that Slate Path Capital LP holds roughly $339 million in STX, while Primecap Management boosted its position by 18.4% in Q2 to about 983,000 shares, part of a broader pattern of large increases from firms like JPMorgan, Vanguard, Wellington and Boston Partners. [27]
On television, Jim Cramer recently described Seagate’s 2025 gains as “remarkable” and added STX to his watch list of AI‑exposed names, further raising the stock’s profile among retail investors. [28]
Valuation check: how expensive is STX now?
Depending on the source, Seagate currently trades at:
- Mid‑ to high‑30s trailing P/E (roughly 36–38x). [29]
- PEG ratios (price/earnings‑to‑growth) around 0.5–1.1, assuming double‑digit earnings growth. [30]
- Price/sales in the mid‑single‑digits. [31]
Fundamental platforms differ in their verdict:
- Simply Wall St has long emphasized that Seagate’s P/E sits well above the market average, but argues that this may be justified if the company delivers forecast earnings growth of roughly 19% per year over the next three years—almost double the broader market’s projections. [32]
- GuruFocus takes a more cautious angle: its quantitative “GF Value” model currently flags STX as “significantly overvalued”, with a price‑to‑GF‑Value ratio around 2.4 and a P/E above the industry median. [33]
- TickerNerd and Stocktwits point out that despite the spectacular run, forward valuation multiples for Seagate and Western Digital are not wildly above the wider tech hardware group—roughly inline with or slightly above the sector’s high‑20s forward P/E—provided growth estimates hold. [34]
In other words, at just under $300, Seagate screens as:
- Cheap if you believe AI‑driven storage demand will deliver many years of elevated growth and high margins.
- Rich if you worry that AI spending will normalize or that HDD demand has been pulled forward.
Insider selling and risk factors to watch
No hot stock story is complete without a note on risks.
- Insider activity
GuruFocus highlights that Seagate’s Executive Vice President & Chief Legal Officer, James Lee, sold 697 shares on November 11, 2025, and that over the past year insiders have logged 46 sales and zero purchases. While insider selling isn’t automatically bearish—it can reflect diversification or planned sales—it does mean leadership is taking some profits near all‑time highs. [35] - Cyclicality and sentiment
The Stocktwits AI‑winner analysis warns that while storage demand is booming now, HDD remains a cyclical industry, and a slowdown in AI‑data‑center capex could hit revenue and margins hard. They also note that retail sentiment toward STX has recently turned “bearish” on their platform, despite the rising price. [36] - Options and hedging
Put/call ratios above 1.0 suggest a meaningful amount of downside hedging, consistent with the idea that some investors are nervous about how much good news is already priced in. [37] - Execution risk on HAMR
Seagate’s lead in HAMR and Mozaic is an advantage, but it also carries technology and manufacturing risk. The company must keep yields high, costs under control and drive reliability at ever‑greater capacities (30TB today, potentially 40TB+ in the next generation). Competitors that close the technology gap—or cloud buyers that seek to diversify suppliers—could compress margins over time. [38]
The bottom line: a 2025 AI star entering 2026 at full speed
As of December 11, 2025, Seagate Technology checks most of the boxes the market loves:
- It is a clear beneficiary of generative‑AI and data‑center build‑outs.
- It has validated next‑gen technology (HAMR / Mozaic) already shipping in volume to top‑tier cloud providers.
- It is posting record margins, strong free cash flow and growing dividends, with guidance that implies continued strength into fiscal 2026. [39]
- Wall Street’s ratings skew strongly positive, and institutional ownership is high. [40]
At the same time, the stock’s massive run‑up, elevated valuation by some metrics, heavy options hedging and cyclical end‑markets mean that expectations are now very high. Future returns will likely hinge on whether AI storage spending remains as intense as 2025’s boom—and how long Seagate can maintain its technological and pricing edge.
For investors and traders following STX into 2026, the story is no longer about whether Seagate has turned the corner. The question now is how long this AI‑driven super‑cycle can run before gravity—and cyclicality—start to reassert themselves.
