SanDisk Surges 5.5% at Close — Index Rebalancing, Not Fundamentals?
SanDisk flipped a 2% intraday loss to close up 5.50%, on MSCI World and ACWI inclusion forcing mechanical passive buying — it gave back 1.06% after hours once the rebalance window shut. Micron rose 2.77% on 22.6M shares, half its 45.6M average; SK Hynix +2.20%. Kioxia and SanDisk committed over $31 billion to capacity, while CXMT's first-half revenue jumped 874% with HBM3E in trial production. 36GB HBM3E spot runs near $2,100, 4–5x contract — but Micron is locked into multi-year deals. Chase the spread, or wait for CXMT's yields?
