SK hynix (HY9H.F) fell 4% in the previous session to €1325 as its rapid surge triggered forced selling from institutional investors hitting portfolio limits. The drop follows a sharp rally sparked by the company's strategic investment in AI leader Anthropic.
- The recent rally was driven by SK hynix's participation in Anthropic's latest funding round, which was announced around May 28.
- The subsequent pullback on May 29 is attributed to significant technical selling pressure, as multiple large funds were forced to trim their positions to comply with single-stock concentration limits after the share price soared.
- This selling pressure is viewed as a technical event—a 'success problem'—rather than a reaction to negative fundamental news about the company.
