SK hynix narrows market cap gap with top-ranked Samsung Electronics
The market capitalization gap between Samsung Electronics and SK hynix has narrowed to a record low, analysts said Friday, as investors reward SK hynix for its early dominance in high-bandwidth memory (HBM) chips, which are vital to AI computing. Shares of Samsung Electronics and SK hynix closed Friday at 97,900 won ($67.2) and 582,000 won, respectively, down 1.3 percent and 2.2 percent from the previous session. Both stocks have entered a correction phase amid renewed concerns about an AI bubble. Nevertheless, the semiconductor industry remains in a clear expansion cycle, with demand rising across the spectrum — from legacy chips to advanced HBM. Among the two, SK hynix has outperformed sharply. Over the past three months, Samsung Electronics' shares have gained 39 percent, while SK hynix has soared 122 percent. As of Friday, SK hynix’s market capitalization stood at 422.2 trillion won, roughly 73 percent of Samsung Electronics’ 580.7 trillion won — marking the narrowest gap on record. Samsung has maintained the No. 1 spot by market cap on Korea’s stock exchange since November
