Micron Technology (NASDAQ: MU), the AI-focused memory and storage chipmaker, closed at $1,051.77, a sharp decline of 13.18% in a single trading session.
The selloff was triggered by weakness in South Korean memory giants SK Hynix and Samsung, with the pain spreading rapidly into U.S. memory names.
The timing proved particularly damaging, arriving just one day before Micron’s closely watched fiscal third-quarter earnings report on June 24.
The broader market also suffered, with the S&P 500 falling 1.43% to close at 7,365.46 as investor sentiment soured across the technology sector.
The Nasdaq Composite dropped a steeper 2.21%, settling at 25,587, reflecting concentrated pressure on high-growth and semiconductor-related stocks.
The global memory chip group absorbed the same selling pressure, with few names in the sector escaping the broad and swift repricing of risk.
Despite the sell-off, a recent agreement with Anthropic has underscored continued demand for Micron’s memory and storage products within AI infrastructure buildouts.
Tuesday’s dramatic drop nevertheless demonstrated how quickly market sentiment can reverse following an extended AI-memory rally that had carried valuations sharply higher.
Investors heading into the earnings report are focused on several key metrics, including HBM demand, DRAM and NAND pricing, gross margin expansion, and fourth-quarter guidance.
The central question facing Micron is whether AI infrastructure demand can be converted into sustained revenue and margin growth that justifies the elevated expectations now baked into the stock.
The sector selloff itself reflects how much optimism had already been priced into memory stocks, leaving little room for any guidance that falls short of bullish forecasts.
With the earnings report now imminent, market participants will be watching closely to see whether Micron can deliver the kind of results needed to restore confidence and stabilize the stock.
