Here's how much MicroStrategy stock is down since Bitcoin's last all-time high

Core Viewpoint - Strategy (formerly MicroStrategy) has experienced a significant decline in its stock price, closely correlated with the downturn in Bitcoin prices, highlighting the volatility and risks associated with its investment strategy in digital assets [1][2][4]. Stock Performance - Since October 6, 2025, MSTR shares have fallen from $360 to $151.86, representing a nearly 58% decrease in less than three months [2]. - The current market capitalization of Strategy is approximately $47.2 billion, reflecting a loss of around $53 billion [3]. - MSTR stock is trading at its 52-week lows and would rank as the sixth worst-performing stock in the S&P 500 if it were included, with a 47.5% decline in 2025 [6][10]. Bitcoin Holdings - Despite the stock decline, Strategy still holds approximately $60 billion worth of Bitcoin, indicating that the company is trading at about 21% below the value of its Bitcoin holdings [3]. - Even if Bitcoin prices were to drop to $75,000, the Bitcoin portfolio would still be valued at roughly $50 billion, with no collateral-backed Bitcoin debt [7]. Strategic Implications - The decline in MSTR shares illustrates the relationship between Bitcoin and the company's market performance, particularly given the aggressive Bitcoin investment strategy promoted by executive chairman Michael J. Saylor [4]. - The volatility in the interplay between Bitcoin and premium valuation may prompt similar companies to reconsider their approaches to digital assets and balance sheets [5].
