Meet the Super Semiconductor ETF Obliterating Nvidia, AMD, and Broadcom This Year

The Roundhill Memory ETF (DRAM) has doubled since its spring 2026 launch, outperforming major AI chip makers by focusing on high-bandwidth memory (HBM), which has become the critical bottleneck in AI supply chains. The ETF holds ~20 memory companies with 75% concentrated in Samsung, SK Hynix, and Micron, benefiting from tight HBM supply and strong pricing power. However, the fund carries significant risks including extreme concentration, high volatility, geopolitical exposure, and the cyclical nature of memory markets.
