Micron Technology (NASDAQ: MU) shares are up 664% over the year but closed 0.27% lower on Friday despite bullish shortage commentary
Micron’s high bandwidth memory (HBM) supply is sold out through 2027, with $100 billion in contracted AI memory revenue through 2030
Fiscal Q4 guidance calls for an 86% gross margin and $31 earnings per share, while rival SK hynix holds a 60% share of the global HBM market
A stock that is already up 664% for the year should not need much more good news to keep climbing — and yet Friday proved otherwise. Micron Technology shares closed 0.27% lower even after SK hynix’s CEO said the memory chip shortage could persist until 2030, a comment CNBC’s Jim Cramer noted echoed what Micron CEO Sanjay Mehrotra had told him directly. South Korea’s KOSPI index also fell on the news, suggesting the shortage narrative is already priced into memory-chip valuations across the board.
Sold-Out Supply Meets Margin Anxiety
On the bullish side, Micron’s HBM supply is sold out for both 2026 and 2027, and management believes its HBM market share can climb to match its 20% to 25% DRAM share by the end of 2027. The company also has $100 billion in contracted AI memory revenue locked in through 2030. But its fiscal fourth-quarter guidance of an 86% gross margin and $31 in earnings per share has raised sustainability questions, particularly with roughly 20% of revenue tied to China and risks from a potential data-center buildout slowdown. SK hynix, which commands a 60% share of the global HBM market, faces a similar debate despite locking in long-term hyperscaler agreements.
What This Means for Your Portfolio and Wallet
For investors holding memory-chip stocks, the flat reaction to bullish shortage news is a signal that further upside likely requires margin durability, not just demand headlines. Portfolios concentrated in AI-memory names should brace for volatility if pricing power softens as rivals ramp capacity.
Strategic Positioning & Defense Ideas
Balancing exposure to memory-chip cyclicality with diversified holdings across the broader tech and industrial sectors can help smooth returns if the shortage narrative shifts.
