Full-line repair of storage chips: SK hynix rises 5% and SanDisk turns positive; concerns about AI demand being a hedge

After earlier choppy consolidation, the semiconductor sector today shows a clearly rebound-and-strengthening trend. This broad rally is not an isolated market move, but rather a concentrated reflection of investors’ renewed risk appetite for tech growth stocks. From a macro perspective, earlier worries about the sustainability of artificial intelligence infrastructure investment are being offset by tangible earnings expectations and order delivery. As a result, capital flows are starting to shift from defensive sectors back toward technology hardware areas with both high beta and high certainty. As a core link in the semiconductor cycle, storage chip pricing volatility directly mirrors changes in the supply-demand landscape. In particular, the urgent need for high-bandwidth storage from servers and data centers has made this sector a key place to watch tech momentum.
