Tech Futures Slide As SanDisk, SK Hynix Plunge; TSMC Falls Despite Strong Earnings

The Quick Take

• Tech futures fell as SanDisk and SK Hynix plunged on earnings and guidance concerns
• TSMC shares sold off despite reporting strong Q2 profit, as guidance disappointed traders
• Chipmaker stocks led pre-market declines with Micron and AMD also under pressure

US technology futures retreated Thursday as semiconductor stocks led a broad pre-market selloff, with SanDisk and SK Hynix at the centre of the downdraft following results and guidance commentary that disappointed traders expecting further upside from the AI memory buildout cycle. TSMC, which had reported strong Q2 earnings the same morning, also sold off as investors rotated out of positions ahead of further earnings announcements from other major semiconductor suppliers.

The simultaneous declines in memory and logic chipmakers highlight the growing sensitivity of semiconductor valuations to forward guidance rather than current-period earnings, with stock prices increasingly priced for near-perfection. SK Hynix's move, in particular, drew attention given the company's central role in supplying high-bandwidth memory chips for AI accelerator packages, where any softness in its guidance carries signal value for the entire AI infrastructure supply chain.

For investors tracking the broader technology sector, Thursday's futures action serves as a reminder that the AI-driven semiconductor bull cycle is not immune to normal earnings volatility and position clearing. Stocks that have run sharply into quarterly events often see mechanical selling regardless of the fundamental result, and the degree to which declines persist into the regular session or are reversed will provide a cleaner read on the underlying institutional conviction in the sector's multi-year growth trajectory.
