Seoul shares plummet nearly 5 pct on tech weakness

SEOUL, July 7 (Yonhap) -- Seoul shares plummeted nearly 5 percent Tuesday as technology stocks extended losses after Samsung Electronics Co. released its preliminary second-quarter earnings estimate. The Korean won fell against the U.S. dollar.

After opening 1.6 percent lower, the benchmark Korea Composite Stock Price Index (KOSPI) extended losses, falling 395.02 points, or 4.91 percent, to close at 7,656.31.

Trade volume was heavy at 512.29 million shares worth 39.66 trillion won (US$25.9 billion), with decliners outnumbering gainers 509 to 358.

Institutions and foreigners sold a net 309.1 billion won and 2.92 trillion won worth of stocks, respectively, while individuals purchased a net 3.13 trillion won.

Technology stocks plunged on profit-taking after Samsung Electronics estimated its operating profit for the April-June period at 89.4 trillion won, beating market forecasts.

Market bellwether Samsung Electronics fell 7.4 percent, while chip giant SK hynix declined 6.4 percent ahead of its planned $29 billion U.S. listing later this week.

The Korean won was trading at 1,528.20 won per U.S. dollar as of 3:30 p.m., down 2.1 won from the previous session.

The Korea Exchange (KRX), the country's bourse operator, activated a circuit breaker for the benchmark index, suspending trading of KOSPI-listed shares for 20 minutes after the index plunged more than 8 percent during the session.
