The ETF Opportunities Trust T-Rex 2X Long MSTR Daily Target ETF (MSTU) closed at $9.91 on February 4, 2025, up 0.81% as MicroStrategy's stock experienced a surge in interest due to significant institutional investments and a positive outlook on Bitcoin. MicroStrategy's stock performance was buoyed by Cullinan Associates Inc. and Sloy Dahl & Holst LLC increasing their holdings, reflecting confidence in the company's strategy and substantial Bitcoin holdings. Bitcoin's rebound to $94,000, following a dip to $90,000, further supported MicroStrategy's stock, driven by a positive shift in market sentiment after U.S. President Donald Trump delayed new tariffs on Canada and Mexico. However, MicroStrategy surprised the market by pausing its Bitcoin buying spree, the first halt in 12 weeks, which led to speculation about the reasons behind this decision. The pause coincides with the company's issuance of perpetual preferred stock and the upcoming earnings release, suggesting potential regulatory or strategic considerations.
