Because this involves a critical global energy shipping route, market risk aversion was instantly reignited, and capital immediately pulled back from the highly volatile and highly leveraged Japanese and South Korean tech sectors.In addition, Samsung Electronics' share price was hit by planned employee protests sparked by inconsistent internal incentives, as well as its newly released, mixed Q2 earnings guidance. According to the published data, total Q2 revenue was 171 trillion KRW, lower than the market expectation of 173.9 trillion KRW, while operating profit was 89.4 trillion KRW, slightly higher than the market expectation of 87.3 trillion KRW.Find out more</div>
