By Reuters | Updated: April 8, 2026

SEOUL, April 8 (Reuters) – Shares of South Korean ​chipmaker SK Hynix (000660.KS) surged on Wednesday ‌after peer Samsung Electronics (005930.KS) forecast market-beating quarterly earnings, fuelling expectations about SK Hynix’s results.

Samsung ​Electronics on Tuesday projected its ​first-quarter operating profit would jump more ⁠than eight-fold, beating analyst estimates ​as booming demand for artificial intelligence ​infrastructure stretched supply and drove chip prices higher.

Korea Investment & Securities on Wednesday raised its ​estimate for SK Hynix’s operating ​profit full-year by 28% to 216 trillion won ($146.55 ‌billion), ⁠more than quadruple from 2025, due to stronger-than-expected price increases of both DRAM and NAND chips.

SK Hynix ​shares traded ​up 15% ⁠at 1,050,000 won ($712.20) each, outperforming Samsung's 8.7% gain ​and the wider market's (.KS11) 7% ​rise.

SK ⁠Hynix, the world’s second-biggest memory chip maker after Samsung Electronics, is set ⁠to ​report January-March earnings later ​this month.
