On August 27, Tradr 2X Long SNDK Daily ETF rose 8.14% in after-hours trading, trading at $14.24/share, with turnover of $40.05 million. The product is a 2x leveraged long ETF on Sandisk, and the underlying stock's after-hours rally amplified through leverage drove the gain.

On the news front, regulatory filings revealed that quantitative trading giant Jane Street significantly increased its Sandisk holdings to approximately 7.41 million shares as of July 29, adding roughly 6.25 million shares — a position increase of nearly 540% — pushing its stake above 5% of Sandisk's outstanding shares. Sandisk rose 3.38% after hours to $1,549.49/share on August 27 following the disclosure. Against the backdrop of Sandisk's recent pullback from highs after a sharp correction driven by Samsung's disappointing shareholder return plan and Jefferies' target price downgrade, the top-tier institution's contrarian accumulation sent a positive signal to the market, triggering a recovery in the leveraged ETF.
