BUZZBERG Alpha Score combines three things: realized average return, confidence in the sample size, idea volume, and speaker reputation. Speakers with only a few calls are pulled closer to the platform average; speakers with many evaluated ideas keep more of their own return. Reputation only boosts: 5.0 or lower is neutral, while scores above 5 add weight. Scores are normalized to 0-100; 100 is best. Read the FAQ

Samsung and SK Hynix undervalued vs profit share
Samsung Electronics and SK Hynix together account for 48% of KOSPI market cap but 72% of its net profit, implying the stocks are not overvalued relative to their earnings contribution. The profit share supports further upside, similar to TSMC's relationship with the Taiwan Weighted Index.

Buy Korean mid-caps with strong profitability
Several mid-cap stocks within the top 100 by market cap have higher rankings in sales growth, net profit growth, operating margin, and ROE than their market cap rank, suggesting they are undervalued and could re-rate. Examples include Samsung Heavy Industries, Korea Aerospace Industries, AP (cosmetics), Samsung E&A, and Hyundai Marine Solution.

KOSPI target 10,379 points from earnings
Based on 2025 KOSPI net profit estimate of 853 trillion KRW and the historical average PER of 9.96x, the KOSPI index can reach approximately 10,379 points. Current PER of 7.7x leaves room for expansion even without a re-rating, and earnings growth supports the target.

Buy Korean earnings/margin improvers
Applying the same earnings revision, QoQ growth, and margin improvement screen to Korean stocks naturally includes Samsung Electronics, SK hynix, and Samsung Electro-Mechanics. Below them, the screen selects aerospace and power equipment names such as Korea Aerospace Industries and Hyosung Advanced Materials, which are tied to defense and power equipment themes. These sectors still lack a major rotation, so stock selection within these themes based on improving fundamentals is key.

Hanmi Semiconductor margins near 50%
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.

Buy US semis with improving margins
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.

Alphabet could overtake NVIDIA as top pick
Alphabet (Google) has been diversifying its revenue through cloud and AI investments, while Nvidia is heavily dependent on data center sales. As Alphabet's cloud segment grows and its AI investments (OpenAI, Anthropic) gain value, Alphabet could become more attractive than Nvidia and potentially overtake it in market cap.
