Odaily News Since reaching its peak on November 20, MSTU, a double-leveraged ETF product that specifically tracks the rise of MicroStrategy (now called Strategy) shares, has fallen by about 81%. In the past three trading days, the ETF has fallen by about 40%, while Strategy's stock MSTR has also fallen sharply by about 20% during the same period. Leveraged ETFs perform poorly when the market is volatile. REX Shares and Tuttle Capital launched this ETF in September last year to provide investors with an investment tool that doubles the rise and fall of MSTR stocks. However, due to the volatility of Bitcoin prices, Strategy shares have fallen by about 15% since the beginning of the year. (Cointelegraph)
