A stock ticker displays the benchmark KOSPI index closing at a record high of 8,788.38, up 3.68 percent from the previous session, at a dealing room of Woori Bank's headquarters in Seoul, Monday.

Yonhap A 63-year-old retiree surnamed Lee in Seoul says stocks have largely replaced bank deposits in his portfolio.

"Since retiring two years ago, I've kept most of my assets in brokerage accounts rather than savings accounts.

I mainly invest in semiconductor stocks such as Samsung Electronics and SK hynix, along with shares of major financial groups," he said.

Lee said he hopes the gains will help cover living expenses and allow him and his wife to travel abroad more often.
