Samsung ships next-gen AI chips and the AI rally won't stop — ride semiconductor momentum
Samsung just started shipping its most advanced AI memory chips to customers, sending its stock up 6%. At the same time, the S&P 500 is on track for its ninth straight weekly gain, powered almost entirely by AI-related stocks — contradicting the old 'sell in May' rule.
Idea
Samsung's new HBM4E memory chips are the latest signal that the AI hardware build-out is still accelerating — these chips go into the data centers powering AI models. When a major supplier like Samsung starts shipping next-generation parts, the companies that design AI chips (Nvidia, AMD) and the broader semiconductor sector tend to keep rallying. The S&P 500 has now climbed for nine straight weeks thanks to AI demand, which tells you the big money is still flowing into this theme. Even though these stocks have already run up, momentum in AI has been self-reinforcing — each new product launch and earnings beat pulls more investors in.
