[Mining Company MARA Stock Drops Over 3%, Downgraded to 'Underweight' by JPMorgan] BlockBeats News, September 14, according to BIT (Bit.com) market data, the stock price of Bitcoin mining company MARA fell by 3.57% today, with its market capitalization dropping to $4.456 billion. On the news front, JPMorgan downgraded the rating of Bitcoin mining company MARA from 'Overweight' to 'Underweight' and lowered the target price from $13 to $11. Analyst Richard Choe believes that MARA's strategy of forming a joint venture with Starwood Capital and shifting part of its mining facilities toward AI and high-performance computing data centers may face issues of 'value dilution.' Additionally, some of the company's mining sites have limited power capacity, making them unsuitable for transformation into data centers.
