Micron and SanDisk drop 5-6% as rising Treasury yields compress their multiples, despite 2026 YTD gains of 255% and 653%. Seagate and the Roundhill Memory ETF each fall 6%, with uniform sector declines confirming a macro rate reset rather than any company-specific news. Act now: the analyst who called NVIDIA in 2010 just named his top 10 AI stocks — and Micron Technology didn't make the cut.
Grab the names FREE today. Memory and storage stocks are selling off Tuesday morning as rising Treasury yields pressure what has been the most extended trade in the semiconductor sector. Three names are anchoring the move.
Micron Technology (NASDAQ:MU) stock is declining 5% to $962.85. Meanwhile, SanDisk (NASDAQ:SNDK) shares are down 6% to $1,681.10. Western Digital (NASDAQ:WDC) stock is cratering 7% to $500.05.
The declines cap a torrid 2026 run for the group. Through Monday's close, Micron stock was up 255% year to date (YTD), SanDisk shares were up 653%, and Western Digital stock was up 211%. Nothing in today's action points to a change in memory fundamentals; this is a valuation reset driven by the cost of capital.
The mechanism is straightforward. Higher Treasury yields raise the discount rate applied to future earnings, which hits hardest the stocks whose valuations lean most on distant results. Yields also raise the financing cost of the fabrication capacity Micron and Western Digital are building, and both channels push in the same direction for this group.
A VIX reading of 14.25 signals no broad panic in equities, and the S&P 500 is only down half a percent. That backdrop supports the read that today is a sector-specific derating rather than systemic stress. Micron, SanDisk, and Western Digital led the semiconductor complex all year, and today they are leading the drawdown.
