Micron's 100-Point Gap Down: What Happened, and Why Wednesday's Print Is Now the Whole Trade
MU and SNDK led the U.S. memory complex lower Tuesday as South Korea's KOSPI crashed 10%, triggered a trading halt, and Samsung and SK Hynix gave back weeks of gains. With Micron reporting fiscal Q3 after the close on Wednesday, the dip is either a gift entry or the first crack in the AI-memory thesis. Here's the read.
Memory got wrecked today.
Micron (MU) gapped down about 100 points, SanDisk (SNDK) dropped roughly 200 points, and the U.S. memory complex traded in sympathy with a 10% crash in South Korea's KOSPI that was deep enough to trigger a trading halt. Samsung Electronics and SK Hynix — the two giants that actually set global DRAM and NAND pricing — led the Korean market lower on what looks like forced profit-taking after one of the most vertical runs in semiconductor history.
Micron reports fiscal Q3 2026 after the close on Wednesday. That print is no longer just a quarterly check-in. It is now the only thing standing between this dip and a genuine reassessment of the AI-memory bull case. Below is what happened, why it happened, and what I think the trade looks like into Wednesday night.
