SK Hynix IncSK Hynix's Q2 report missed expectations and guided for massive capex increase, triggering sector rout.
SanDisk shares fell 7% to $1,019 and Micron Technology dropped 6% to $775 as a memory-sector selloff intensified on Wednesday. The rout was triggered by SK Hynix's second-quarter report, which delivered a record operating profit up 557% year over year and a record 76% operating margin but missed expectations, and more importantly guided for a 50% increase in 2026 capital expenditure to at least $31 billion, stoking fears of an overheating AI capex cycle. SanDisk has collapsed 36% over five days, while the Roundhill Memory ETF fell 4% to $46 and is down 20% over the same period. Bucking the trend, Seagate Technology gained 2% to $759 after beating fourth-quarter earnings estimates, highlighting a stark divergence between HDD-focused storage names and NAND/DRAM memory names. The Philadelphia Semiconductor Index is down 19% in July, on pace for its worst month since 2008, with all members below their 50-day moving averages.
