Morgan Stanley Research Report Analysis: The HDD Cycle Has Not Ended, Yet the Market Prices It as Peaked

By Rita
The market prices hard disk drives (HDDs) at an 8x P/E ratio, implying the cycle peaks in FY28. In its October 20, 2026 report, Morgan Stanley presents a contrary view: the cycle has not ended, and this pricing is overly punitive.
Demand is accelerating. Nearline HDD spot transaction prices are 4 to 7 cents/GB, while hybrid nearline contract prices are approximately 1.5 cents/GB. The industry faces a supply shortage of approximately 400 exabytes (EB) in CY27/CY28, compared to 300 EB in CY26. Customer bases are expanding from core cloud service providers (CSPs) to AI labs, which aim to secure 100% of EB capacity.
Morgan Stanley reiterates its Overweight ratings on Seagate Technology (STX) and Western Digital (WDC), with STX returning as its top pick in IT hardware. Target prices are $1,200 for STX and $643 for WDC. WDC features lower buy-side expectations and a more tactically favorable earnings setup.
8x P/E Ratio Implies Cycle Peak
Morgan Stanley backs into the valuation using FY28 earnings assumptions and an 80% price drop for solid-state drives (SSDs). The current ~8x P/E implies that HDD earnings peak in FY28, with SSD prices falling 80% from their C2Q26 levels. MS considers this assumption overly punitive.
HDD demand is accelerating, supply shortages are widening, and spot prices significantly exceed contract prices. Non-nearline HDD prices increased by 15% to 30% sequentially. Valuations exhibit positive asymmetry.
Morgan Stanley lowered its target multiple from 20x to 15x (STX) and 14x (WDC), reflecting market structural shifts and AI financing uncertainties. Target prices are $1,200 for STX (15x FY28 EPS of $80.10) and $643 for WDC (14x FY28 EPS of $45.95). Current prices are $660.81 for STX and $352.21 for WDC.
Spot Prices Far Exceed Contract Prices
Nearline HDD spot transaction prices range from 4 to 7 cents/GB, with hybrid nearline contract prices around 1.5 cents/GB. Clients seek to purchase 100% of the EB capacity, but supply shortages restrict procurement volumes. Storage capacity deficits are driving up spot prices.
Non-nearline HDD prices rose 15% to 30% sequentially. Seagate is more aggressive than Western Digital in capturing spot prices. Demand is expanding from core CSPs to AI labs. Toshiba is constrained by media and equipment, with CY27 capacity already sold out, leading to more aggressive pricing. Morgan Stanley is comfortable with Toshiba's risk profile.
December Quarter EPS Beats Consensus
Seagate's September quarter EPS is expected at $7.50 against a market consensus of $7.41; Western Digital's September quarter EPS stands at $4.13 versus a consensus of $4.09. Seagate's December quarter EPS is $9.54, 12% above market consensus. If spot pricing assumptions prove more aggressive, December EPS could rise another 5%.
Western Digital's December quarter EPS is $5.25, 10% above market consensus. Under more aggressive spot pricing assumptions, December EPS could reach $5.67. Buy-side expectations for WDC range from $4.75B to $4.95B in revenue, 59.5% to 61.0% gross margin, and $5.20 to $5.60 EPS. WDC guidance is typically conservative.
MS views WDC's earnings setup as tactically favorable due to lower buy-side hurdles. STX remains 10% above its high-conviction buy valuation level (10x CY27 EPS = $595), while WDC is only 3% above ($343).
Cycle Not Over, but Path Forward Blurs
MS acknowledges the catalyst path for HDDs is blurrier than a month ago. Markets hold uncertainty regarding vendor rationality and AI funding sources, which won't be resolved by earnings reports. Target multiples were reduced by 5 to 6x.
Demand checks support upside surprises and guide-up potential. MS focuses on four questions: whether STX/WDC will adjust capacity plans in response to Toshiba's targets; whether profit prioritization comes before market share gains; whether the supply/demand gap will widen; and whether more aggressive pricing emerges. Answers to these may not restore the stock to its narrative from four months ago, but will help investors recognize that certain risks are already priced in.
Morgan Stanley reiterates its Overweight ratings on STX and WDC, with STX back at Top Pick. The market prices in a cycle end, while MS prices in a cycle continuation.
