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/SK hynix lead sharp snapback bounces.
After sharp selloffs, Samsung Electronics and SK hynix consistently lead snapback bounces. When circuit breakers hit and panic spikes, buying these two names for a short-term rebound trade the next day remains profitable because of their overwhelming weight and liquidity.

National Growth Fund stocks lead market recovery.
The National Growth Fund has approved massive direct equity investments into specific companies such as LIG Nex1 and LigaChem Bio, with more to come. Even though these stocks sold off on the news, companies backed by government funds tend to lead when the market recovers, so they are worth accumulating on weakness.

Semiconductor equipment stocks benefit from mega capex.
Samsung's disclosed 1,000-trillion-won 10-year capex plan and similar SK Group spending are a near-term positive for semiconductor equipment makers. The investment cycle is multi-year, so oversupply fears are 4–5 years away. Equipment companies will see strong order flow and valuations can expand now.
