SanDisk Loses One Kweichow Moutai in Market Value in a Day—Buy the Dip or Run for Your Life?
SanDisk opened sharply lower last night, at one point down more than 9%. SK Hynix fell 9.2%, Seagate fell 9%, Western Digital fell 7.4%, and Micron fell 7%.
The five storage giants suffered a collective bloodbath.
The Philadelphia Semiconductor Index plunged 4.98%. The Nasdaq fell 1.33%.
What does losing 9% in a day mean? SanDisk shed about $160 per share in market value in a single day.
Those buying the dip are shouting “golden opportunity,” while holders are asking, “Should I get out?”
Let’s first talk about why it fell.
There were three direct reasons:
First, it had risen too much. SanDisk surged 3,415% over the past year—you read that right, 34-fold. Any asset that rises this much is sitting on a time bomb of profit-taking. An Aptus Capital fund manager put it bluntly: “Investors have begun taking profits and shifting into cash after the recent sharp gains in AI hardware stocks.”
Second, long-term bond yields surged. The yield on 30-year U.S. Treasuries hit a 19-year high. AI and semiconductor sectors, which are highly sensitive to long-term funding costs, took the brunt of the impact. Put simply—money has become more expensive, so capital-intensive businesses get hit first.
Third, the market is waiting for an answer. Anthropic’s annualized revenue exceeded $65 billion, but “appears slightly below recent market expectations.” How quickly will AI commercialization actually take hold? The market has no clear answer.
On the very day SanDisk plunged, JPMorgan gave it a $2,250 price target.
Bank of America reiterated its “buy” rating on Micron, with a $1,550 price target, 61% above the stock price at the time.
For the same stock, the market was selling while top institutions were buying.
The core disagreement comes down to one question: Is storage still a cyclical industry?
In the past, memory chips were standard cyclical products—soaring wildly when prices rose and collapsing when prices fell, with fortunes dependent on market conditions.
But SanDisk is trying to rewrite that script.
It signed long-term supply agreements with eight major data-center customers at once, lasting up to five years and guaranteeing $93.9 billion in revenue. In fiscal 2027, long-term contract orders will cover more than half of flash shipments; in 2028, they will cover two-thirds.
What does that mean?
SanDisk’s revenue used to depend on NAND prices, with negotiations taking place every quarter. Now, its shipment volumes and prices for the next four to five years are locked in.
Bank of America’s logic is this: If SanDisk can turn a cyclical business into a “recurring revenue” business, Micron can follow the same path through AI-driven HBM demand and supply discipline. Bank of America forecasts that Micron’s fiscal 2030 earnings per share could reach $200 to $250, and that its valuation should be re-rated from the historical 10x P/E to 12x–15x.
In plain English: If storage is no longer cyclical, today’s valuation is the floor, not the ceiling.
So what was last night’s plunge?
I think two narratives are colliding—
Short-term narrative: After rising more than 600%, profit-takers want out; long-term bond yields are surging; and market sentiment is tightening. A 9% drop is entirely reasonable.
Long-term narrative: Demand for NAND driven by AI inference is only just beginning. SanDisk expects the potential market for flash storage in enterprise data centers to expand to 1.2 zettabytes by 2030. That number is so large that most people have no intuitive grasp of it—let’s just say it is a lot.
The head of technology research at Freedom Capital put it quite aptly: “Memory companies currently have extremely strong fundamentals, but bearish investors are still waiting for an inevitable collapse in storage-chip prices.”
Both bulls and bears have valid points. It all depends on your time horizon.
My view: This is a normal correction, not the end of the rally.
Why?
Because the long-term storage thesis has not been broken—AI needs storage and computing power, and inference needs NAND. That is a law of physics, not market sentiment.
One remark from SanDisk’s CEO is worth pondering: “Some top customers applied for additional flash procurement allocations for the following several years just one quarter after signing long-term purchase contracts.”
Customers themselves are chasing additional orders. Do you think they are fools?
But there is one condition—you have to be able to withstand the volatility.
SanDisk rose 34-fold in a year, but can also fall 9% in a day. The holding experience for an asset like this is more than most people can handle.
An ActivTrades analyst cautioned: “Given the astonishing recent stock-price gains, volatility and profit-taking pressure in high-beta technology stocks may remain elevated.”
In plain English: More turbulence is coming.
If your position is too large, trim it a little so you can sleep at night.
If your position is small, wait for the stock to stabilize before reassessing.
If you have no position, don’t rush to buy the dip—wait for the market to give you the answer, rather than trying to give the market one.
The long-term storage story has not changed, but short-term volatility can shake you out of the trade.
