South Korean stocks ended markedly higher Friday to extend their winning streak to a fourth session as investors pinned hopes on a turnaround in the global semiconductor sector amid eased fears over the global banking turmoil. The local currency fell against the US dollar.

The benchmark Korea Composite Stock Price Index added 23.7 points, or 0.97 percent, to close at 2,476.86. Trading volume was a bit heavy at 705.36 million shares worth 12.51 trillion won ($9.62 billion), with gainers outpacing decliners 480 to 407.

Foreign and institutional investors bought a net 517.3 billion won and 207.16 billion won worth of shares, respectively, while retail investors sold a net 721.12 billion won worth of shares.

The index opened higher, tracking overnight gains on Wall Street, and maintained the momentum throughout the session.

"Investors digest the global banking sector turmoil, and the Philadelphia Semiconductor Index rose 1.62 percent to raise optimism about a turnaround," Kiwoom Securities analyst Han Ji-young said. "The passage of the K-Chips Act will also serve as a positive factor for the domestic tech sector."

On Thursday, the National Assembly passed the act, which calls for expanding the tax credit rate for facility investment by chipmakers and other national strategic sectors.

The semiconductor index hit the highest level in nearly a year Thursday on growing hopes for surging demand for artificial intelligence technology, according to foreign media reports.

Analysts also pointed to budding signs of a recovery in the Chinese economy, as China's Premier Li Qiang noted his nation's economy has gained momentum for a rebound.

Investors now await the release of the US' core personal consumption expenditures price index, key inflation data, Friday (local time) in order to gauge the Federal Reserve's monetary policy path.
