Strategy’s stock (MSTR) climbed 16.39% on Friday to close at $153.92, after starting the day at $132.25 and touching an intraday high of $154.02, as Bitcoin moved back above $80,000. The gain lifted MSTR’s one-month return to approximately 48% through Sept. 18, placing it at the top of the Nasdaq-100 constituent return ranking. Trading volume reached about 54.3 million shares, well above recent daily levels.
The move came as Bitcoin rose more than 5% Friday, fueling renewed interest in crypto-linked stocks. Strategy has historically amplified Bitcoin’s moves: on Friday, MSTR gained 16% while Bitcoin rose about 5–6%. As of Sept. 13, Strategy held approximately 845,050 BTC, acquired for a total cost of $63.73 billion, including fees and expenses, at an average purchase price of about $75,412 per Bitcoin. Its last confirmed purchase was 4,603 BTC for roughly $369.7 million.
According to the latest SEC filing, Strategy did not buy or sell Bitcoin between Sept. 8 and Sept. 13, and made no sales under its at-the-market stock program. Instead, the company spent cash repurchasing STRC preferred stock: $176.3 million for 1.81 million STRC units between Aug. 31 and Sept. 7, followed by another $139.3 million in the next reporting period. Executive Chairman Michael Saylor posted “A little more orange” on Sunday alongside an accumulation chart, a pattern he has used before confirmed purchase disclosures. No new Bitcoin transaction has been officially reported, so the confirmed balance remains 845,050 BTC.
