Micron (MU) Stock Plunges Over 10% Amid Global Semiconductor Selloff

TLDR

• Micron shares declined an additional 2.18% in Thursday’s premarket session to $1,009.76, after plummeting 10.6% Wednesday to settle at $1,032.28.
• Global contagion sent South Korea’s KOSPI benchmark tumbling 7.9%, with memory chip competitors SK Hynix and Samsung plunging 14.6% and 9.1% respectively.
• Year-to-date gains through Wednesday still show Micron ahead by 262%, trading approximately 128% above its 200-day moving average.
• Critical support zone identified near $991; falling through this level may trigger additional downside pressure.
• Wall Street maintains optimistic outlook with consensus price target of $1,542.05, while Cantor Fitzgerald and Barclays project $2,000.

Micron Technology (MU) shares experienced significant turbulence this week, collapsing 10.6% during Wednesday’s session to settle at $1,032.28, then extending losses with a 2.18% decline in Thursday’s premarket trading to approximately $1,009.76. This two-session retreat represents part of a wider semiconductor sector downturn that triggered volatility across domestic and international markets.

The selling pressure transcended American markets. South Korea’s KOSPI benchmark — which has been among 2026’s strongest-performing global indices — closed Thursday’s session down 7.9%. With heavy concentration in memory chip manufacturers, the index bore the brunt of sector-specific weakness. SK Hynix plummeted 14.6% while Samsung retreated 9.1%. These companies compete directly with Micron in DRAM and NAND memory segments.

Despite recent volatility, Micron‘s broader performance trajectory remains impressive. Through Wednesday’s close, shares have surged 262% year-to-date — performance that eclipses most Wall Street benchmarks. The KOSPI maintains an 81% gain for 2026 despite Thursday’s pullback. Meanwhile, the S&P 500 has advanced a modest 9.3% during the same period.

However, short-term technical indicators reveal emerging weakness. Micron currently trades approximately 4.1% beneath its 20-day simple moving average of $1,048.47, suggesting the immediate trend is undergoing consolidation following the stock’s June peak. The relative strength index registers at 51.95 — neutral territory — indicating the shares are pausing rather than experiencing fundamental breakdown.

Key Levels to Watch

Market participants are monitoring two critical price thresholds. Overhead resistance exists around $1,089.50, representing the level Micron must reclaim to reestablish bullish momentum. Conversely, downside support emerges near $991. Breaching this floor could trigger additional selling pressure.

For perspective, Micron continues trading roughly 19.5% above its 50-day moving average of $841.56 and approximately 128.4% above its 200-day moving average of $440.26. These metrics suggest the long-term uptrend remains fundamentally sound.

Micron maintains substantial ETF representation. The stock commands an 8.39% allocation in the Invesco S&P 500 Momentum ETF (SPMO), a 9.78% weighting in the Invesco PHLX Semiconductor ETF (SOXQ), and a 9.46% position in the Global X DAX Germany ETF (DAX). Such concentrated ETF exposure means institutional fund flows can magnify price movements in either direction.

Earnings and Analyst Targets

Micron’s upcoming quarterly earnings release is scheduled for September 22, 2026. Wall Street consensus anticipates earnings of $31.24 per share — a substantial increase from $3.03 reported in the prior-year period. Revenue projections stand at $50.72 billion, dramatically exceeding last year’s $11.31 billion. These forecasts illustrate extraordinary growth momentum.

The stock currently trades at a price-to-earnings multiple of 23.3, which analysts view as reasonable compared to semiconductor industry peers.

Analyst sentiment remains decidedly bullish. Consensus price target for MU sits at $1,542.05. Cantor Fitzgerald elevated its target to $2,000 on June 29, while Barclays established an identical target on June 25. Cantor’s previous target stood at $1,500.

Micron’s Benzinga Edge metrics support the optimistic thesis: momentum score of 99.62, quality score of 97.83, and growth score of 85.15. The lone weakness appears in valuation, scoring just 24.83 — reflecting concerns about how rapidly shares have appreciated.

As of Thursday’s premarket session, MU traded at $1,009.76, down 2.18%.
