Western Digital hit $799.87 on June 18. It is now trading near $489. That is roughly a 39% round-trip in less than two months, and today the selloff accelerated again.
WDC stock is falling Thursday due to a broad, sector-wide selloff in semiconductor and artificial intelligence memory stocks driven by massive profit-taking. But the real pressure is more specific than that.
Memory-related chip companies face additional headwinds following news regarding ChangXin Memory Technologies. The Chinese memory peer filed to raise almost $10 billion in a Shanghai initial public offering, signaling growing competition across the global semiconductor sector. That is not a minor headline. CXMT going public with up to roughly a $9.8 billion raise (depending on overallotment) is a direct signal that China’s domestic memory ambitions just became publicly funded at scale. The market read it immediately.
Slight tangent, but it matters: Western Digital shares slid 10.8% to $458.22 on July 16, wiping out $19.2 billion in market value. That is a single-session loss larger than most S&P 500 companies’ total market caps. The volatility here is not noise. It is a feature of what happens when a stock runs 10x in a year and then the competitive landscape shifts.
The Kioxia Angle
Underneath the selloff, there is a story that could eventually change the math. Claims that Western Digital “initiated renewed discussions” with Kioxia on July 15 could not be verified from a credible primary source.
Here’s the thing: this is not Western Digital’s first attempt to combine with Kioxia. Prior reports (in earlier years) have described on-and-off discussions that ran into valuation and regulatory issues, and the strategic logic—scale in flash—has not disappeared. But investors should treat any “deal structure” specifics as unconfirmed unless and until they appear in a company filing or an on-the-record report.
Ironically, any merger speculation tends to surface alongside selloffs. Markets are messy like that.
What WDC Actually Is Right Now
Western Digital is no longer a NAND/SSD company. The SanDisk spinoff in February 2025 made WDC a pure-play HDD business, with 89% of revenue now coming from cloud and enterprise nearline drives. AI training and inference data requires massive cold-storage capacity, HDD is the only cost-effective solution at scale, and WDC’s entire 2026 production is already sold out.
That sold-out production figure is the one the market keeps forgetting in weeks like this. Despite the current downward trend, financial analysts maintain a bullish outlook on the memory-chip maker. BofA Securities analyst Wamsi Mohan said that tight NAND supply and demand conditions could persist through 2027, with pricing expected to remain resilient through at least the middle of 2027.
The Options Picture
Option traders were moderately bearish in Western Digital, with shares down near $513 at the time of that read. Options volume ran roughly in line with average at 57,000 contracts. The put-to-call lean into a stock down more than 30% from its high is telling. Institutional desks are still hedging, not capitulating outright.
UBS has a $560 target and keeps a Neutral rating. The $240 spread between the Citi and UBS same-day calls equals 43% of the share price and is the clearest investor signal. Using fiscal 2027 earnings estimates of $18.02 a share, the UBS target values WDC at about 31 times earnings while Citi’s values it at 44 times. That dispersion is not a modeling error. It is a genuine disagreement about how long HDD pricing power holds as CXMT scales.
For traders who believe the NAND competitive threat is overstated and the July 29 earnings report confirms HDD demand remains sold out, a defined-risk call spread targeting a recovery toward the $540 to $560 range captures the move without full downside exposure. For those who think CXMT’s IPO (up to roughly $9.8 billion with overallotment) is the beginning of a pricing cycle disruption that will take quarters to play out, a put spread into the August expiry reflects that view with defined risk. For a neutral posture, a short straddle positioned around the $490 to $500 range through July 29 expiry monetizes the elevated implied volatility without requiring a directional bet.
The Earnings Date Is the Only Thing That Matters Now
The next catalyst is Q4 FY26 earnings on August 5, where guidance of roughly $3.65 billion in revenue and $3.25 EPS will be the key test. That number either confirms that AI storage demand is still structural and the pullback was a sector rotation, or it reveals that hyperscaler procurement really is moderating and the 10x run in 12 months was pricing in perfection the business cannot sustain.
Both are real possibilities. The options market is telling you which one the institutional money is leaning toward right now. The question is whether you agree with that lean or think the market is getting this one wrong.
