South Korea's stock market staged a remarkable comeback on Friday, with the KOSPI index surging more than 18% after three straight days of heavy losses. The sharp rise put the benchmark index on track for its biggest single-day percentage gain on record.

So, what fuelled this dramatic rally? Here are the three key reasons.

AI AND CHIP STOCKS BOUNCED BACK

The biggest driver of Friday's rally was the strong rebound in artificial intelligence (AI) and semiconductor stocks.

SK Hynix and Samsung Electronics jumped more than 23% each, while Taiwan Semiconductor Manufacturing Co. (TSMC) gained around 10%. These companies were the biggest contributors to the rise in the MSCI Asia Pacific equities index.

The rebound came after investors returned to AI-linked stocks following a sharp three-day sell-off.

STRONG RALLY IN US TECHNOLOGY STOCKS

The positive mood in Asia followed a strong overnight session on Wall Street.

US chip stocks recorded their biggest one-day gain in more than a year, boosting confidence across global markets. Nasdaq 100 futures also pointed to further gains after the technology-heavy index ended a six-day losing streak.

Investor sentiment received another boost after Amazon reported strong earnings, sending its shares up 9.5% in after-hours trading. Apple, however, fell more than 6% after warning that supply shortages could affect its sales outlook.

INVESTORS BOUGHT BACK STOCKS AFTER A STEEP FALL

Friday's rally also came after a sharp correction in the KOSPI over the previous three trading sessions.

The index had fallen more than 17% as investors sold technology stocks amid concerns over an AI bubble and growing competition from Chinese companies in AI and chipmaking.

After the sharp decline, investors returned to buying beaten-down technology shares, helping the market recover strongly.

Markets remain cautious

Despite Friday's record rally, investors continue to watch global developments closely.

Markets are assessing the strength of the US economy and whether the more than 20% rise in oil prices this month could push inflation higher. Brent Crude prices edged lower on Friday as shipping through the Strait of Hormuz showed signs of improving despite continued tensions in the Middle East.

Even after the sharp rebound, the KOSPI remains well below the record high of over 9,000 that it reached in June.
