MU Grinds to $810 as Samsung Strike Countdown Tightens the Memory Tape

The Strike Clock

The cleanest catalyst into this print is calendar risk, not headline risk. Samsung Electronics' national union, the largest in the company's history, has approved an 18-day general strike beginning May 21 after a 93.1% vote and a failed government mediation over profit-linked bonuses. Jefferies' read, echoed by TrendForce's contained-but-price-supportive scenario, pegs the realistic disruption at roughly 3% of global memory output — small in absolute terms, large for a market where contract pricing is already set on the assumption that nothing slips. TrendForce's own framing matters here: even if Samsung's revenue impact stays contained, the order-shift risk lands directly on SK hynix and Micron, the only two suppliers with the capacity and qualifications to absorb redirected HBM and high-end DRAM bookings.

Why The Bid Keeps Coming

The price action is not running on the strike alone. Bank of America's near-doubling of its MU price target to $950 from $500 re-rated the entire sell-side band on a refreshed $1.7 trillion AI data center TAM through 2030, with Deutsche Bank and DA Davidson already parked at $1,000. Underneath those calls is the fundamental that does the actual work: Micron's calendar 2026 HBM supply is sold out, HBM4 high-volume production pulled in a quarter earlier than guided, and order books extending into 2027. Q2 guidance of $18.70B at a 68% non-GAAP gross margin is what the strike narrative is being layered on top of, not a substitute for. That is why a sub-5% daily move on a stock already up ~116% off the April low still gets faded into and bought back.

Where The Trade Breaks

The setup has obvious failure modes worth pricing. Insiders have been trimming on the way up, RSI has flashed overbought above 85 ahead of the print, and the Motley Fool valuation case lays out the standard cyclical-peak warning for anyone underwriting a $900B+ market cap on a memory name. The clean binary is the strike itself: a last-minute settlement on May 20 likely takes the fastest 5–8% off the top, while a strike that actually runs the full 18 days hands Micron and SK hynix a pricing reset they did not have to engineer themselves. Above ~$815 the tape is in price discovery; the level traders are watching on the other side is the prior consolidation shelf near $780, where the BofA-driven gap from yesterday fills.
