Micron Plunges 11% in a Single Day: Is This the “GPU Before the Mining Crash,” or “the Last Panic Before Getting In”?
Brothers, it’s another night of rivers of blood.
The Philadelphia Semiconductor Index (SOX) has slid from a high of over 14,600 points a month ago to just over 10,400 points now. On July 17, it officially fell below the 20% threshold, confirming entry into a technical bear market.
Micron Technology closed down 10.9% on Wednesday, marking its biggest single-day drop in recent times. Starting from its historical closing high of $1,213.56 on June 25, it has cumulatively fallen by about 30%, and its market cap has evaporated by about $414.95 billion.
SanDisk has been cut in half over a month, and SK Hynix’s ADR breaks the previous level. The entire memory sector looks no different from the crypto market’s big-cap plunge.
Now everyone is asking the same question:
Is this the “GPU before the mining crash,” or “the last panic before getting in”?
Don’t rush to pick a side. Let’s see how the bulls and bears tear into each other—
🟢 Bull logic: This is a bad overreaction—a deep V after SOL blew up following the FTX collapse
First, Micron’s fundamentals haven’t broken down; if anything, they’re insanely strong.
Micron’s FY2026 Q3 revenue was $41.46 billion, up 346% year over year, setting a record high. Net profit was $28.24 billion, up 14x year over year. Gross margin was 84.9%—higher than Nvidia’s 75% and Meta’s 81.9%, the highest among large-cap tech companies in the U.S.
The company signed 16 strategic customer agreements covering $100 billion in long-term investment. Management expects supply constraints to last through 2027. Q4 guidance calls for revenue of $49 billion to $51 billion, while the market expects only $43.2 billion.
Earnings aren’t just strong—they’re historically strong.
Second, the demand logic for HBM from AI hasn’t broken.
HBM’s value share in AI servers has surged from 7% in 2021 to more than 25% of GPU costs. HBM production in 2026 is expected to grow 103% year over year, and then rise another 77% in 2027. Samsung expects server DRAM, enterprise SSDs, and HBM demand to accelerate in the second half of the year, and the overall market will still be in short supply.
AI’s hunger for storage is like miners’ hunger for compute—logic hasn’t broken; it’s just market panic.
Third, analysts are still going crazy bullish.
The median target price from 54 analysts is $1,600. KeyBanc reiterated an “overweight” position with a $1,750 target. The average target price is $1,507, implying more than 100% upside from the current share price.
The bulls say: this sharp drop is emotion being purged, not a collapse in fundamentals. If you don’t buy the dip now, are you waiting to chase after it bounces back?
🔴 Bear logic: Be careful! This is the first big bearish candle after LUNA’s collapse
First, memory demand could be peaking.
Morgan Stanley issued a warning on July 21: the AI storage frenzy is nearing a turning point, and memory contract prices are expected to top out in the fourth quarter. The earnings-upgrade momentum has fallen from a 92% peak to 77%. Year-over-year growth in DRAM contract prices has already come off from the cyclical highs.
If prices can’t keep rising, earnings growth will slow down. What the market fears most is not earnings declining, but earnings growth declining.
Second, China’s DRAM giants are coming.
On July 27, Chinese ChangXin Memory Technologies (CXMT) listed on A-shares. It surged more than 460% on the first day, and its market cap broke above 3 trillion. The market is worried that after ChangXin Memory Technologies receives massive financing, it will expand production capacity, ramp up technology R&D, and even challenge the high-end HBM market.
The global DRAM supply landscape could change fundamentally. How long can Micron, SK Hynix, and Samsung’s oligopoly position hold?
Third, deleveraging in the Korean market is far from over.
Since the beginning of the year, Korean retail investors have been aggressively levering up to bet on Samsung and SK Hynix. The balance of credit financing surged from 27.4 trillion Korean won in early January to a peak of 38.6 trillion Korean won on June 24.
Then the trend reversed.
Leveraged ETF mechanisms force rebalancing—“add when it rises, cut when it falls.” When markets rise, it acts like a booster; when markets fall, it becomes a meat grinder—margin calls → forced liquidation → further declines → more margin calls. Once a negative-feedback spiral starts, it doesn’t shift based on anyone’s will.
Credit financing balances fell to 32.7 trillion Korean won on July 23, but the decline wasn’t nearly enough. Forced liquidations are still continuing.
The bears say: a sharp drop doesn’t necessarily mean the bottom. Highly leveraged funds haven’t been fully liquidated yet. If you buy now, be careful not to catch it halfway up the mountain.
🤔 My take:
This round of storage selloff is the result of three forces stacking together.
First, profit-taking. Micron has risen more than 700% over the past year, and SK Hynix and Samsung have risen even more wildly. Any asset that’s up 7x—once even a little wind blows, money will run.
Second, cycle fear. The memory industry is always a strong cyclical sector. When it rises, it rises crazily; when it falls, it falls crazily. Morgan Stanley says prices will top in Q4, and the market chooses to run early.
Third, deleveraging stampede. Korean retail investors’ leveraged positions are being forced to clear. This isn’t pricing based on fundamentals—it’s passive selling. What’s the characteristic of passive selling? It doesn’t care about reason or valuation; it only wants to close positions.
So is it the bottom, or just halfway up the mountain?
My answer is: in the short term, there may still be volatility, but in the medium to long term, the bulls’ logic is stronger.
Why?
Because HBM isn’t ordinary DRAM—it’s the “compute-and-memory” for the AI era. Nvidia’s GPUs can’t do without HBM, just like mining rigs can’t do without graphics cards. As long as AI training and inference continue, HBM demand won’t stop.
Samsung expects supply gaps to expand quarter by quarter in the second half of 2026, and new capacity releases are generally delayed until after 2027. If the supply-demand gap is still widening, how can prices collapse?
In the short term, ChangXin Memory Technologies entering the high-end HBM market still faces high technical barriers, and the structure of the global AI storage market is unlikely to change fundamentally in the near term.
But the problem is—right now the market doesn’t talk logic, it only talks sentiment.
Korean deleveraging hasn’t finished, and forced liquidations are still going on. Until this “bleeding” stops, any dip-buying could be catching falling knives.
📌 So my strategy is:
Watch three signals—
Signal one: Korean credit financing balances stabilize (currently 32.7 trillion; the peak was 38.6 trillion—still needs to keep falling)
Signal two: the amount of forced liquidations falls back to normal levels (currently still at the several-hundred-billion-KRW level)
Signal three: the SOX index stops falling and stabilizes (currently 10,400 points—getting farther and farther from the threshold)
Until these three signals appear, keep your hands off.
Once the signals appear—
Micron’s current share price still corresponds to analysts’ target prices with more than a 100% upside. A company with an 85% gross margin, 346% revenue growth, and $100 billion in long-term agreements—after it has dropped 30%—do you think it’s expensive or cheap?
