The AI chip stock boom is showing severe cracks at the start of the third quarter, with massive sell-offs spreading from the US to Asia. Traders are questioning the massive spending on AI, making the recent winners highly vulnerable to a larger drop.

## Idea

Memory and chip stocks like Micron saw historic rallies in Q2, but Q3 is opening with a brutal hangover. Micron already wiped out $200 billion in value in a single day. The panic is spreading globally as South Korean and Japanese chip stocks fall sharply, driven by fears that companies like Meta selling computing power signals an oversupply of AI capacity. When a leading sector like semiconductors shows this kind of global, cascading weakness right after a record run, it often signals a broader shift in investor sentiment. Betting against the recent winners (or buying put options on them) is a high-probability way to play this sudden loss of momentum.
