Samsung Electronics and SK Hynix, which saw sharp declines the previous day, both rebounded today (June 24).

On the KOSPI market today, Samsung Electronics closed at 340,500 won, a sharp increase of 9.84% from the previous trading day.

Starting the day at 314,000 won, up 1.29%, Samsung Electronics fluctuated before firmly establishing an upward trend in the afternoon.

SK Hynix closed at 2,580,000 won, up 0.98% from the previous trading day.

SK Hynix opened at 2,598,000 won, up 1.68%, and fell as low as 2,453,000 won—a 3.99% drop—during the session. However, like Samsung Electronics, it showed strength in the afternoon and shifted to a rise.

Following the 12.31% and 12.47% plunges of Samsung Electronics and SK Hynix yesterday, and the 7.87% drop in the Philadelphia Semiconductor Index overnight in New York due to concerns over artificial intelligence valuation burdens and market highs, a massive influx of bargain hunting led to the rebound.

In particular, investor sentiment appears to have been significantly stimulated by media reports suggesting that Samsung Electronics is expected to soon initiate a share buyback program nearing 90 trillion won.

According to industry sources, Samsung Electronics is currently preparing additional share buybacks to provide special performance bonuses and is expected to announce detailed plans in the near future.

As a result, the market capitalization of Samsung Electronics' common shares reached 1,990.6579 trillion won as of the market close today, surpassing SK Hynix's 1,838.7721 trillion won to reclaim the top spot on the KOSPI after two trading days.

On the KOSPI market today, individual and institutional investors net bought 2.6084 trillion won and 1.9123 trillion won, respectively.

Foreign investors net sold 4.6322 trillion won.
