Memory Chip Makers Rally on AI Supercycle Thesis

Memory semiconductor stocks have entered a parabolic phase, with Micron, SanDisk, Broadcom, AMD, and Intel all posting sharp gains as traders embrace a "supercycle" narrative. The thesis rests on three pillars: AI data-centre buildouts requiring massive DRAM and NAND capacity, elevated chip prices sustained through 2027, and margin expansion that justifies premium valuations even at historically high forward multiples. JPMorgan raised its Kospi target to 10,000, citing the semiconductor cycle, while analysts flagged that memory-chip forward PE ratios remain "very low" relative to earnings growth expectations.

Call skew has hit record levels while put skew has collapsed to historic lows, signalling massive retail and quant positioning in upside calls. One analyst flagged the first stage of a parabolic move: gap-and-go breakaways, sideways consolidation, then exhaustion gaps. Multiple posts warned of pump-and-dump dynamics in lower-float names (MRAM, RXT) and questioned whether a "fire sale" would follow.

Equipment makers like ASML are benefiting from capex flows. However, sceptics point out that memory-chip pricing is commodity-like and vulnerable to oversupply; one analyst explicitly warned that "a shitbox Chinese factory announcing 50% discount on latest RAM tech would be doomsday." Energy shocks and potential rate hikes could dampen capex cycles. The tension between momentumThe empirical fact that winners keep winning over the medium term.-driven technicals and fundamental risks is acute.

This froth raises crash risk; bear capitulation and record call positioning typically precede reversals.
