The Tradr 2X Long SNDK Daily ETF (SNXX) experienced a significant 24-hour plunge of 12.76%. The leveraged ETF, designed to deliver twice the daily return of SanDisk Corp. (SNDK), saw heightened volatility surrounding SanDisk's fiscal third-quarter earnings release, with sharp moves occurring in the pre-market, intraday, and after-hours sessions.

The decline was primarily driven by a reversal in SanDisk's share price following its earnings report. Despite SanDisk reporting explosive third-quarter results that significantly surpassed market expectations—with revenue reaching $5.95 billion and adjusted EPS at $23.41—its stock fell in after-hours trading. This reaction reflects investor concerns about high valuations, as SanDisk's shares had already surged approximately 360% year-to-date and over 3300% in the past 12 months, pricing in substantial optimism about AI-driven demand.

Analysts note that the storage sector is benefiting from an AI-driven supercycle, with massive data center investments fueling demand for NAND flash memory. However, the market reaction to SanDisk's stellar performance indicates skepticism about the sustainability of such exceptional growth rates and potential profit-taking after the earnings announcement. As a 2x leveraged product, SNXX amplifies these underlying price movements, leading to the magnified decline.
