South Korea's Patriotic Theme Stocks Surge 237% in 15 Days on Social Sentiment, Not Fundamentals

According to Korea Exchange, Hansung Enterprise shares surged 237.67% from July 1–15, 2026, while market cap jumped from 26.7 billion won to 90.1 billion won. Monami shares rose 173.41% in the same period, reaching 65.1 billion won market cap. The rally was driven by social media campaigns calling to save domestic brands facing delisting risk after the government raised the KOSPI threshold to 30 billion won in July.

However, earnings data reveal the danger. Enex posted a 22.59% revenue decline and 2.87 billion won operating loss in Q1 2026, while Monami's operating deficit surged to 27.1 billion won. Financial experts warn that theme-driven rallies reverse sharply when sentiment shifts—gold-standard example Kum Ho Construction soared 250% in early July before falling 44.84% within one week. Investors should verify underlying business fundamentals rather than rely on price momentum alone.
