The KOSPI advanced for five consecutive trading days last week, with foreign investors posting 6.5 trillion won in net buying over the week — accounting for much of this month's index gains.

Yeo Han-koo, Minister for Trade Negotiations at the Ministry of Trade, Industry and Energy, has been abruptly removed from his post. Having been widely regarded as the key figure who led working-level negotiations throughout last year's Korea-US tariff talks, his dismissal has turned the direction of his successor's appointment and any potential shift in negotiating stance into the next variable to watch for the KRW/USD exchange rate and for stocks (tickers) in industry sectors with heavy exposure to US exports.

Samsung Electronics' (005930) minority shareholder count neared 8 million in the first half of this year, meaning roughly one in five Korean adults now holds the stock.
