Vicor is trading 8.18% down at $222.51 as broad semiconductor weakness and rising Treasury yields pressured AI and growth stocks on August 19, 2026.
- The decline follows a 4.37% drop on August 18, despite bullish company news: 2026 revenue guidance above $600 million and nearly 10% expected sequential third-quarter growth.
- SOXX fell 2.50% during regular trading, making today’s move appear sector-driven rather than tied to a new Vicor-specific negative announcement.
