The GraniteShares 2x Long MU Daily ETF (MULL) is designed to achieve investment returns, before accounting for its fees and expenses, that are double (200%) the daily percentage change of Micron Technology Inc.'s common stock (NASDAQ: MU). It's important to note that there's no assurance the fund will consistently meet this daily target. Investors should also be aware that, due to the impact of compounding, this fund should not be anticipated to deliver two times the cumulative return of MU over timeframes longer than a single trading day.
