After a record plunge and rebound in July, South Korea\'s KOSPI marked time in August as volatility eased. September direction is expected to hinge on whether U.S. long-term yields stabilise, foreign funds return and gains broaden beyond semiconductors. Analysts cite improving profit forecasts, low forward valuations and rising shareholder returns as supportive. Risks include higher U.S. rates and foreign selling, while key U.S. data and Fed meetings will guide rate expectations.

South Korea\'s KOSPI fell more than 5 percent soon after the open on Tuesday, triggering a sell sidecar that temporarily halted program sell orders on the main board. As of 9:09 a.m., the index was down 381.32 points, or 5.64 percent, at 6,374.43. Foreign investors and institutions were net sellers, while retail investors bought. Samsung Electronics and SK Hynix fell, while Samsung Biologics rose.
