Applying the same earnings revision, QoQ growth, and margin improvement screen to Korean stocks naturally includes Samsung Electronics, SK hynix, and Samsung Electro-Mechanics.

These sectors still lack a major rotation, so stock selection within these themes based on improving fundamentals is key.

Hanmi Semiconductor has a very high price-to-earnings ratio, but its operating margin is rising sharply and is expected to reach nearly 50% by Q2-Q3 2024. This margin level is approaching that of Samsung Electronics, indicating that despite the high valuation, the company's extreme profitability improvement justifies the multiple and supports the stock.

In a high interest rate environment, the key is to focus on companies with upward EPS revisions, strong quarter-over-quarter EPS growth, and improving operating margins. Applying this screen to US stocks, semiconductor hardware names dominate. Broadcom, Micron Technology, and AMD pass all criteria, while NVIDIA is excluded because its QoQ EPS growth is currently lower than the S&P 500 average. The semiconductor hardware theme continues to lead.
