Asian stock markets surrendered early gains on October 29 as investors reacted to contrasting technology earnings, with South Korean shares and U.S. stock-index futures moving lower.

Investing.com reported South Korea’s KOSPI down nearly 3% in early Thursday trading and Samsung Electronics down nearly 6%. Reuters’ earlier snapshot also showed a substantial decline, with the KOSPI off 2.6% and Samsung more than 4% lower. These are intraday observations, rather than final closing results.

Samsung’s retreat followed record quarterly operating profit. Investors were assessing the earnings against expectations and waiting for details of its next shareholder-return policy. The company said that policy would be finalized in January, according to Investing.com.

U.S. results provided a sharply divided backdrop. Alphabet fell about 10% in after-hours trading following its earnings release, while Microsoft gained about 3%. Reuters and Investing.com linked the contrasting responses to cash-flow performance and the cost of artificial-intelligence infrastructure investment.

Nasdaq futures were lower during the Asian session. Amazon and Intel were due to report later Thursday, extending a week of major technology results.

The regional picture was mixed beneath the broad decline. Investing.com reported modest gains in Japan’s Nikkei 225 and Australia’s S&P/ASX 200, while mainland Chinese indexes fell and Hong Kong’s benchmark was largely flat.

The moves followed small gains in U.S. regular trading on October 28, when the Federal Reserve left interest rates unchanged. The S&P 500 closed at 7,743.98, the Dow Jones Industrial Average at 52,475.10 and the Nasdaq composite at 26,549.85, according to the Associated Press. Each gained less than 0.3%.
