Shares opened higher on Tuesday, tracking overnight gains on Wall Street, amid growing expectations of the U.S. Federal Reserve's interest rate cut and market-friendly tax reform measures.
The benchmark Kospi added 4.88 points, or 0.15 percent, to 3,224.47 in the first 15 minutes of trading.
Overnight, U.S. stocks gathered ground as a weaker-than-expected August jobs report reinforced expectations that the Fed would start reducing rates soon. The Dow Jones Industrial Average rose 0.25 percent, and the tech-heavy Nasdaq composite gained 0.45 percent. The S&P 500 index went up 0.21 percent.
Investors also welcomed the news that Finance Minister Koo Yun-cheol on Monday hinted at the possibility of revising the government's earlier proposal on the criteria for major shareholders subject to capital gains tax on stock transactions.
The Finance Ministry had previously proposed lowering the threshold for capital gains tax on stock holdings from 5 billion won ($3.61 million) to 1 billion won, a move that has drawn criticism from investors.
