SK Hynix vs. Micron: The Memory Trade Turns Into a 20% Valuation Gap

The setup: Micron's premium sits against SK hynix's HBM lead

Micron trades at roughly a 20% valuation premium despite holding about one-third of SK hynix's HBM share. That gap is the heart of the trade.

What the market is debating

• Bull case: SK hynix controls the scarcer asset. It holds 58% HBM market share versus Micron's roughly 20%, yet trades at only about 5.8 times forward earnings to Micron's 7 times. If investors keep valuing AI memory leadership through actual HBM scarcity, Micron's premium could compress.
• Bear case: Micron may simply deserve the higher multiple because it is the U.S. listing. SK hynix's Nasdaq ADR debut on July 10 was seven times oversubscribed, but broader U.S. investor access really improved after the launch rather than before it.

Why the timing matters now

The latest listing activity has made the relative valuation easier to compare, but this still looks like a slow re-rating story. A Zacks strategist said it would take months, not weeks for SK hynix to close the valuation gap with Micron. If HBM leadership is the key value driver, the adjustment should come gradually rather than in a sharp replay.
