SK Hynix and Samsung Shares Swing Over 20% Amid Investor Frenzy

South Korean technology stocks experienced extreme intraday volatility, with SK Hynix and Samsung Electronics each swinging more than 20% in a single session after earlier double‑digit declines. Investors described the market as a "gambling arena" and some reduced holdings, while analysts warned the swings are driven by noise rather than fundamentals.

Influencer Mi‑ja publicized her recent SK Hynix purchase on social media, showing the stock had fallen over 13% since her buy. Her post sparked a wave of criticism from online followers, many demanding refunds for their losses. The episode highlighted the impact of popular personalities on market sentiment.

Industry experts pointed to single‑stock 2× leveraged ETFs as amplifiers of the volatility, noting that these products delivered near‑zero returns during the rally‑fall cycle. Despite the turbulence, several brokerages raised price targets for both companies, citing solid earnings outlooks and ongoing memory‑chip demand.
