On July 21, Direxion Daily Semiconductor Bull 3X Shares (SOXL) rose 5.18% overnight, trading at $143.78/share, with turnover of $295 million.

On the news front, the rebound was driven by multiple catalysts. AMD officially launched its first rack-scale AI system Helios and announced Microsoft as a new customer, a move widely viewed as a direct challenge to NVIDIA's dominance in AI computing. This significantly boosted market confidence in semiconductor demand growth driven by AI infrastructure investment.

The ETF had plunged nearly 15% in the prior session due to South Korean regulatory tightening and a broad semiconductor selloff. The Korean central bank explicitly dismissed the semiconductor peak narrative, stating AI infrastructure investment continues to drive demand beyond supply, with this upcycle far exceeding historical averages. DRAM contract prices also rose sharply quarter-over-quarter, confirming no fundamental deterioration. Additionally, investors are focused on upcoming tech earnings this week, with expectations that positive signals from companies like Intel could provide further upside momentum.

The fund seeks daily investment results equal to 300% of the daily performance of the ICE Semiconductor Index, which tracks the 30 largest U.S.-listed semiconductor companies.
