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

Hold 30%+ Samsung and SK hynix.
The Korean stock market is heavily concentrated in Samsung Electronics and SK hynix due to AI semiconductor demand. Hyper-scaler capex is surging well above expectations and is driven by US-China competition, ensuring continued investment. Semiconductor export data remains strong, supporting the thesis. Investors should allocate at least 30% of their portfolio to these two stocks.

Naver's B2B AI pivot with Nvidia.
Naver is transforming from a B2C advertising-led model to a B2B AI infrastructure provider, backed by a strong Nvidia partnership that supplies GPUs and gives it unique access to Korea’s massive user data. The historic volume spike in the stock signals fresh market interest, and the B2B AI revenue roadmap—projecting 0.85 T KRW by 2027 rising to 17 T KRW by 2031—offers a clear re‑rating catalyst. With government and Nvidia having already set the stage, Naver is now at an attractive entry price to start building a position and watch the AI transition unfold, despite residual skepticism.
