- The KOSPI 200’s strong performance is highly concentrated in AI Memory Semiconductor stocks, suggesting the need for a protective measure against sector-specific volatility.
- An impending labor strike at Samsung Electronics poses a short term risk complicating calculations regarding the current geopolitical environment. The strike may reduce Korea’s GDP, which warrants downside portfolio protection.
