# U.S. stock night trading volatility: Bitcoin fluctuations and executive sell-offs hit Strategy stock price down 3.36% in after-hours trading

**U.S. Stock Night Market Movements**

Strategy fell 3.36% in the night market. Based on recent news,

1.  On November 17, Strategy's stock price dropped to $192, the lowest point since the end of 2024, with a market value evaporating by about $72 billion. The volatility in the Bitcoin market directly affected Strategy's stock performance.
    
2.  On November 19, Strategy's Executive Vice President Shao Wei-Ming sold 5,200 shares of company stock at a price of $200, totaling $1.04 million. This insider trading raised market concerns about the company's prospects.
    
3.  On November 20, JP Morgan warned that if indices like MSCI remove Strategy, it could face billions of dollars in capital outflows.
