Asset manager Vanguard has trimmed its stake by 10%, in Michael Sayor’s Strategy (previously MicroStrategy), during the second quarter of 2025. This comes as the MSTR stock has lost its volatility and has been trading in a very tight range over the past four months, finding support at $360. The recent trimming of stake by the largest shareholder, Vanguard, has raised questions on the stock’s near-term trajectory.
