The leveraged ETFs MSTX and MSTU, which aim to deliver twice the daily move of MicroStrategy (MSTR) stock, have suffered severe losses, dropping about 95% over the past year compared to MSTR's 67% decline. These ETFs use daily reset mechanics and synthetic exposure via swaps and options, which cause volatility decay and tracking errors, especially during choppy trading. MSTX has a larger asset base but higher fees, while MSTU offers a lower expense ratio. Both are better suited for very short-term trades, as holding them longer leads to significant value erosion unless MSTR enters a smooth, sustained uptrend.
