The Tradr 2X Long SNDK Daily ETF (SNXX) experienced a significant pre-market plunge of 8.53% on Wednesday. As a leveraged product designed to deliver twice the daily return of its underlying asset, the ETF's sharp decline was directly tied to movements in SanDisk Corporation's stock.

The drop was primarily driven by profit-taking activity in SanDisk shares following a substantial intraday rally in the previous session. SanDisk had surged over 5% during regular trading after investment firm Bernstein raised its price target significantly, citing new-generation long-term agreements that are reshaping the memory industry business model. However, investors subsequently locked in gains, causing SanDisk to fall more than 3% in after-hours trading.

This pullback in the underlying stock was amplified by the ETF's 2x leverage mechanism, resulting in the steeper decline. The movement follows a period of exceptional volatility for SanDisk, which had seen its stock price skyrocket over 850% in the first half of 2026 amid structural supply-side constraints in the NAND flash memory industry, creating conditions ripe for profit-taking after significant price advances.
