RMBC seeks to deliver 200% of the daily performance of Rambus Inc. (TICKER: RMBS), through derivatives such as swap agreements and exchange-traded equity futures to create leveraged exposure. Rambus is a global semiconductor company providing industry chips and silicon IP for data-intensive computing systems, focusing on data center and artificial intelligence (AI) infrastructure. The portfolio is rebalanced at the end of each trading day to maintain its targeted leverage level, meaning returns over periods longer than a single day can differ significantly from two times the cumulative return of RMBS due to compounding effects. Collateral supporting these derivative positions may be invested in money market instruments, repurchase agreements, or short-term US government securities.
