Chipmakers SK Hynix and Micron join $1tn club on surging AI demand - BBC
SK Hynix and Micron have both crossed the $1 trillion valuation mark as AI-driven demand for HBM and high-bandwidth memory accelerates, with MU up ~19% today alone. The milestone signals a sentiment regime shift for memory chips, but parabolic single-day moves and heavy insider selling at MU set up a classic buy-the-news exhaustion risk.
What happened
SK Hynix and Micron have both crossed the $1 trillion valuation mark as AI-driven demand for HBM and high-bandwidth memory accelerates, with MU up ~19% today alone.
The read · May 26
Fade the MU gap-up near $895 — insider selling (54 sales, zero buys last 30d) and a 19% single-day rip on milestone news screams distribution into retail euphoria.
Wrong if
Trade fails if Micron drops a surprise guidance raise or NVDA announces expanded HBM orders, either of which could keep the memory rally running well past the $1T milestone and squeeze any short position hard.

The read, in fullWhy it matters
MU is up 19% in a single session on a symbolic valuation milestone — exactly the kind of event that attracts retail momentum but where smart money exits. The insider data is telling: 54 sells and zero buys in the last 30 days suggests insiders were staging distribution ahead of this print. Consensus is already heavily bullish (17 Strong Buy / 32 Buy), meaning the upgrade cycle is largely priced in and there's limited incremental positive re-rating to drive a sustained move higher from these levels.
