The stock market delivered a brutal lesson in how quickly sentiment can turn for even the hottest names in artificial intelligence. Micron Technology soared to an all-time high above €1,000 on Monday, only to capitulate in spectacular fashion by the end of the week. Over two sessions, the memory-chip maker shed more than 17% of its value — a 13% plunge on Thursday followed by a 12% freefall on Friday — leaving shareholders nursing a €755 close that stands nearly 20% below the week’s peak.
What made the reversal so jarring was the collision of three distinct headwinds, none of which individually dismantled the company’s core thesis, but together overwhelmed it. The first blow landed when Broadcom disappointed with its third-quarter AI chip revenue guidance of $16 billion, shy of the $17.2 billion consensus, and declined to raise its full-year forecast. That sparked a sector-wide rout: the Philadelphia Semiconductor Index tumbled 10.3% in its worst session since March 2020, erasing roughly $1.3 trillion in market value across U.S. chipmakers. AMD fell 12.6%, Intel dropped 9%, and Asian names like Samsung and SK Hynix slid 6.4% and 10%, respectively.
The second shock came from Washington. The May U.S. jobs report delivered 172,000 new positions, more than double the 80,000 economists had forecast. The data crushed lingering hopes for near-term rate cuts and, according to the CME FedWatch tool, even reintroduced the risk of a rate hike before year-end. For a high-growth name like Micron, whose valuation depends on discounting future cash flows far into the horizon, a “higher for longer” interest-rate regime is a structural headwind. The stock had no shelter.
The third trigger, uniquely Micron’s own, arrived mid-day Friday when independent research firm SemiAnalysis published a note speculating that NVIDIA might halve the modular memory capacity of its forthcoming Vera Rubin server architecture from 55 terabytes to 28 TB. Investors read it as a threat to demand for high-bandwidth memory (HBM), Micron’s crown-jewel product for AI servers. The sell-off was immediate and vicious. Hours later, SemiAnalysis clarified that the note “had no bearish intent” and that the modular DRAM in question (SOCAMM) does not overlap with the HBM business. By then, the damage was done.
Good news buried under bad headlines
The irony is that the week began with a genuine milestone. NVIDIA CEO Jensen Huang confirmed during a visit to Seoul that Micron had passed HBM4 qualification for the Vera Rubin platform, joining SK Hynix and Samsung as an approved supplier. Vera Rubin systems are expected to ship in the third quarter of 2026, and the certification locks Micron into one of the most coveted supply chains in the semiconductor industry. The market largely ignored it.
Should investors sell immediately? Or is it worth buying Micron?
Yet the fundamental picture — the one that drove the stock up roughly 181% year-to-date and more than 730% over the past twelve months — remains intact. In its fiscal second quarter, Micron reported revenue of $23.9 billion, up 196% year over year, and an operating margin of 69%. For the third quarter, management guided to a record $33.5 billion in revenue, with a gross margin near 81%. CEO Sanjay Mehrotra revealed that Micron currently meets only 50% to 66% of customer demand for HBM, a scarcity that keeps pricing power firmly in the company’s hands.
That scarcity underpins the bullish case. Raymond James lifted its price target to $1,100, Morgan Stanley to $1,050, and UBS analyst Timothy Arcuri set a Street-high $1,625. Susquehanna had earlier called for $1,750. On the opposite end, Goldman Sachs remains the prominent skeptic with a target near $400, warning that memory chips are inherently cyclical. The analyst consensus in Europe sits at €635, a level the stock still trades 16% above — a sign that even before this week’s correction, the market had priced in more than the average analyst considered fair.
The June 24 reckoning
Technically, the stock is no longer stretched. The relative strength index stands at 56, a neutral reading that leaves room to move in either direction. But the fundamental narrative will be tested on June 24, when Micron reports its fiscal third-quarter earnings. Consensus calls for earnings per share of $18.97 to $19.19, compared to $1.73 a year earlier. The company’s own revenue guidance of $33.5 billion already towers above analyst estimates of $22 billion to $24 billion.
Whether the AI memory cycle is strong enough to justify the premium — or whether the Broadcom shock, the jobs surprise, and a hastily written analyst note are early warnings of a peak — will be decided in three weeks. For now, the stock is caught between a real growth story and a market that punishes any hint of imperfection.
