Why is SoftBank Group stock tumbling today?

SoftBank Group (9984) fell 4.2% after reporting a ¥1.12 trillion net loss for Q2 2026, down from a ¥2.5 trillion profit a year earlier. The loss was driven by a $3.7 billion charge on U.S. AI data center projects and a 23% drop in Arm Holdings' share price. The Vision Fund segment also swung to a loss. The Nikkei 225 rose slightly, indicating the decline was company-specific.
