The Tradr 2X Long SNDK Daily ETF (SNXX) experienced a significant 24-hour surge of 8.92%. The leveraged ETF, which aims to deliver twice the daily return of SanDisk Corp., saw substantial gains across pre-market, intraday, and after-hours trading sessions, reflecting amplified bullish momentum in the underlying stock.

The rally was primarily driven by SanDisk's outstanding fiscal third-quarter results, which massively exceeded analyst expectations for revenue and earnings per share. This strong performance triggered a wave of analyst upgrades, with several firms significantly raising their price targets for SanDisk, contributing to the positive sentiment.

Further bolstering investor confidence were SanDisk's strategic business developments. The company secured multiple long-term supply agreements with minimum revenue guarantees and financial collateral, greatly improving future revenue visibility. Additionally, progress in High Bandwidth Flash (HBF) technology development and a strategic equity investment in Nanya Technology to secure DRAM supply strengthened the company's market position and long-term growth outlook, fueling the leveraged ETF's ascent.
