SK Hynix Stock Tumbles Over 34% This Month Ahead of Q2 Earnings on July 29

According to F&Guide, SK Hynix stock has tumbled approximately 34% this month amid broader semiconductor sector weakness driven by international oil price spikes, foreign profit-taking, and concerns about slowed memory demand from improved Chinese AI model efficiency. The chipmaker is set to report Q2 earnings on July 29, with consensus operating profit forecast at 64.23 trillion won, up 597.2% year-over-year.

Investors are closely focused on management commentary regarding HBM (high-bandwidth memory) pricing, AI chip demand trajectories, and capital expenditure guidance. Recent optimism from Alphabet's stronger-than-expected results and expanded AI infrastructure investment pledges has eased concerns about AI investment slowdown, though analyst KB Securities expects an "AI efficiency paradox" where higher model efficiency drives expanded memory demand and AI capital spending.
