On September 14, Vicor fell 6.02% in pre-market trading, trading at $186.0 per share, with turnover of $85,600. The decline follows a sharp rally of over 10% on September 11, when the company announced plans to acquire two properties in New Hampshire for chip manufacturing capacity expansion, triggering profit-taking pressure as gains unwound.

On the news front, Vicor plans to purchase a 334,000-square-foot building in Merrimack and a 54-acre parcel in Hooksett to construct two new wafer fabrication facilities totaling nearly one million square feet, aimed at scaling production of its AI power delivery technology. While the expansion signals long-term growth ambitions, the rapid run-up in share price over preceding sessions has invited selling pressure from short-term holders locking in gains.

Within the Electrical Components and Equipment sector, broad-based weakness compounded the pullback. Among peers, Vertiv Holdings fell 5.84%, Emerson declined 3.29%, Eaton dropped 3.23%, Rockwell Automation slipped 0.84%, and Ametek was flat. The sector-wide downdraft amplified downside momentum in the stock.
