Market read
The AI‑driven memory rally lifts Samsung and SK Hynix, with spillover to global semiconductor sentiment.
What to watch
Potential supply‑side constraints from new capacity additions in 2027‑2028 may temper long‑term upside.
Background
AI agents like Meta's Muse require high‑performance DRAM, prompting a rally in memory stocks worldwide.
