AI Expectations Hit a Fever Pitch

Samsung Electronics reported a 19-fold profit surge that triggered circuit breakers on the Korean market, yet semiconductor and AI stocks are selling off as investors reassess stretched valuations against fundamentals. The earnings beat highlights the AI infrastructure boom, but traders are dumping shares across the sector despite record results.

Amazon (AMZN) and Alphabet (GOOGL) continue pouring capital into AI infrastructure buildouts, part of the hyperscaler spending wave fueling chip demand. The disconnect between strong earnings and weak stock performance signals concern that current multiples have priced in years of growth already.

Lockheed Martin (LMT) is acquiring Ultra Maritime to add sonar capabilities, part of a broader defense-sector pivot toward smaller drones and digital systems. The shift reflects budget pressure and changing military doctrine favoring distributed, lower-cost platforms over traditional big-ticket weapons systems.

The Samsung circuit breaker underscores the volatility embedded in AI-related names, where even blowout quarters can trigger profit-taking if sentiment turns.
