South Korean stocks have extended a sharp slide, cutting the combined market capitalisation of the KOSPI and KOSDAQ by nearly 19 percent so far this month. Korea Exchange data showed the combined value stood at 6,057.134 trillion won at Monday’s close, down 1,386.351 trillion won since June 30. Market value has fallen sharply amid worries over a peak in the semiconductor cycle, renewed U.S.-Iran geopolitical tensions and rising oil prices.

South Korea\'s KOSPI rebounded after nearly a 9 percent drop a day earlier, supported by bargain buying from foreign investors and institutions. The index finished up 0.73 percent at 6,856.83 after opening lower and briefly rising to the 6,900 level. The KOSDAQ fell 1.92 percent to 783.98 and failed to regain 800 after a sell sidecar was triggered during the session.
