ScanTech AI shares surge 16.75% after-hours as market weakness drives sector rotation toward tech.

ScanTech AI Systems Inc. surged 16.75% in after-hours trading, driven by a broader market shift toward technology stocks amid sector rotation. The stock's pre-market rise of 10.15% highlighted its resilience as the Nasdaq-100 and S&P 500 declined, signaling investor confidence in the company's AI-driven security solutions. Analyst Emily J. Thompson noted that Scantech's advanced CT screening technologies and strategic positioning in the AI sector may have attracted renewed interest, particularly in a weak market environment. The after-hours gain suggests continued momentum as investors bet on the firm's innovation in non-intrusive threat detection and its relevance to critical infrastructure sectors.
