T-Rex 2X Long MSTR Daily Target ETF (MSTU) is trading 3.9% down today, magnifying losses as its underlying stock, MicroStrategy (MSTR), continues to slide. - The decline follows a hawkish Federal Reserve policy signal on June 17, which held rates at 3.50%-3.75% but indicated potential future hikes, pressuring high-beta assets like MSTR. - Additionally, MicroStrategy is facing mounting concerns over its STRC financing vehicle and speculation about the potential sale of Bitcoin to cover dividend payments, contributing to MSTR's extended selloff on June 18. - Due to MSTU's 2x daily leverage structure, these combined pressures on MicroStrategy are resulting in magnified losses for MSTU shareholders.
