A significant trader has shorted Samsung Electronics and SK Hynix on the Hyperliquid platform using 4x leverage, with a position valued at $13 million. This move comes as the Korea Composite Stock Price Index (KOSPI) surged, triggering a circuit breaker during trading hours. Despite the short position, Samsung Electronics and SK Hynix saw substantial gains, rising 7.5% and 12.9%, respectively. SK Hynix's performance was particularly strong, driven by its collaboration with NVIDIA to develop next-generation memory, pushing its share price above USD 1,400.
