S&P Global Ratings has assigned MicroStrategy a 'B-' issuer credit rating, categorizing it as a junk bond due to its significant Bitcoin exposure and low dollar liquidity. The rating reflects concerns over the currency mismatch between its Bitcoin-denominated assets and dollar-denominated debt. Despite this, TD Cowen maintains a 'buy' rating for MicroStrategy, setting a price target of $620, citing the company's ongoing Bitcoin accumulation strategy. MicroStrategy recently increased its Bitcoin holdings to 640,808, valued at $74 billion, following a $43.4 million purchase. The company's stock saw a 3% increase, trading at approximately $298.
