A whale address locked in about $186,000 of profit after fully closing 2,908.3 SKHX long contracts and 2,323.9 SNDK long contracts over the past day, but would have seen combined gains reach about $1.385 million at this morning's highs if the positions had been held. That left about $1.2 million in missed upside, roughly 6.5 times the profit actually realized. The two positions were closed for a combined notional value of about $5.945 million. SKHX was exited at an average price of $1,022.9 for about $17,000 in realized profit, but later rose as high as $1,207.4, implying about $537,000 in missed gains. SNDK was exited at an average price of $1,278 for about $169,000 in realized profit, then climbed to $1,563.3, implying about $663,000 in additional missed upside. After the exits, SKHX and SNDK rose as much as 18.0% and 22.3%, respectively, versus the whale's average sell prices. The trader has not reopened long exposure and instead has taken the other side with a 10x isolated short of 2,524.2 SNDK contracts, worth about $3.902 million, at an average entry of $1,553.2. That short was showing about $18,000 in unrealized profit, with a liquidation price of $1,936.
