The KOSPI touched the 7,000 mark during trading today (the 22nd) before paring its gains to finish in the 6,700 range.
The retreat appears to reflect cautious sentiment ahead of Alphabet's earnings release, which is seen as a turning point for the artificial intelligence rally.
The KOSPI closed up 49.75 points, or 0.74%, at 6,797.70 compared to the previous session.
The index opened up 304.14 points, or 4.51%, at 7,052.09 from the previous trading day and surged as high as 7,166.00 during the session.
This marks the first time in four trading sessions since the 15th that the KOSPI has surpassed the 7,000 threshold during trading.
As a result, a sidecar for program buying was triggered on the main bourse.
This marks the 40th sidecar activation overall this year and the 20th for buy orders.
However, upward momentum weakened in the afternoon, wiping out most of the earlier gains.
Although foreign investors posted net purchases in the trillions of won for the first time in a while, selling by retail and institutional investors left the index moving sideways.
On the main stock market, foreign investors were net buyers of 2.6311 trillion won, while retail and institutional investors were net sellers of 1.2278 trillion won and 1.3868 trillion won, respectively.
Foreign investors recorded a net selling advantage of 43 billion won in the KOSPI 200 futures market.
The won-dollar exchange rate stood at 1,480.1 won, up 6.7 won from the Seoul foreign exchange market at 3:30 PM.
The KOSPI rose sharply in the morning, driven by strong buying centered around the two semiconductor giants.
This followed broad gains across all three major indexes on Wall Street overnight, including the Nasdaq Composite, alongside a 5.21% surge in the Philadelphia Semiconductor Index.
However, the upward trend slowed in the afternoon due to growing caution ahead of the earnings report from Google parent Alphabet, scheduled to be released early tomorrow morning Korean time.
In the wake of this, Samsung Electronics finished the regular session up 0.58% at 260,500 won, while SK Hynix fell 0.33% to close at 1,830,000 won.
SK Hynix briefly climbed as much as 9.26% to 2,006,000 won during the session, briefly recovering the 2 million won mark before ultimately slipping.
Nevertheless, foreign investors net bought 1.2563 trillion won in SK Hynix and 583.4 billion won in Samsung Electronics, respectively.
They ranked first and second in net purchases.
Other top market-cap shares also saw their morning gains narrow or turned lower by the end of the session.
Samsung Electro-Mechanics (2.67%), Hyundai Motor (4.76%), and LG Energy Solution (1.26%) advanced, whereas SK Square (-1.84%), Samsung Biologics (-1.65%), and Shinhan Financial Group (-0.19%) declined.
By sector, communications (5.08%), construction (4.62%), and transportation equipment and parts (3.02%) gained, while medical and precision equipment (-6.48%), textiles and apparel (-1.27%), and pharmaceuticals (-1.18%) fell.

The KSDaq index finished down 2.25 points, or 0.30%, at 751.09.
The index opened up 19.07 points, or 2.53%, at 772.41 from the previous session and showed gains of over 4%, but its upward momentum slowed in the afternoon before turning downward just before the close.
Retail investors were net buyers of 263.8 billion won, whereas institutional and foreign investors were net sellers of 191.4 billion won and 84.2 billion won, respectively.
Among top market-cap shares, EcoPro BM (1.51%), EcoPro (2.53%), and Rainbow Robotics (16.28%) rose, while Alteogen (-1.83%), Jusung Engineering (-4.26%), and Wonik IPS (-3.79%) dropped.
In the KSDaq market, advancing stocks totaled 839, declining stocks 793, and unchanged stocks 103.
