MU Fades to $790 as Korea AI Tax Aftershock Bleeds Into Profit-Taking

The Korea Tax Aftershock

On Tuesday, May 12, South Korean President Lee Jae-myung's chief of staff posted on Facebook floating a windfall profits tax on the AI economy to fund a national dividend. The post wasn't legislation, wasn't specific, and didn't name any companies, but the tape took it seriously and ripped roughly $100 billion out of Micron's market cap intraday before settling 3.6% lower on the session. By Wednesday Micron had clawed back about 3.2% as the desk consensus pointed out the obvious: Micron makes no chips in Korea, so even a finalized Korean windfall tax would not directly touch its P&L. The 24-hour fade to ~$790 is the second-order move — the relief bid getting trimmed as traders price the residual risk that the idea travels to Beijing or Washington before it dies.

A Parabolic Tape Looking for a Reason to Rest

The Korea story is the spark; the kindling is the stock itself. Micron is still up roughly 89% over the trailing month and finished Tuesday less than 1% off the all-time closing high near $815. That sort of vertical generates its own mean-reversion gravity: the marginal long has a thirty-handle of profit to defend, and any plausible-sounding bear headline becomes an excuse to ring the register. Morgan Stanley flagged the same dynamic across the broader chip complex this week, framing the recent semis selling as positioning rather than a fundamental break.

Samsung's Strike Clock Is Still Ticking

The structural setup hasn't moved. Samsung's union voted 93.1% in favor of an 18-day walkout starting May 21, and the most recent mediated talks with management collapsed. TrendForce sees the direct revenue impact on Samsung as contained but expects pricing support across DRAM and NAND, with order risk shifting toward SK hynix and Micron — exactly the tightening-supply setup the bull case has been pricing into Micron's June quarter. With the walkout seven days out, today's pullback reads as the tape pricing time decay on a binary event, not a re-rating of the thesis.
