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

SK hynix will rebound after passive selling.
The recent correction in SK hynix is driven by passive/index fund selling and option expiry overshooting, not active selling of the stock itself. Volume is low, indicating that the selling is not aggressive. After the correction, SK hynix will resume its uptrend. Investors should hold or buy on dips, not sell.

Samsung Electronics will recover after passive selling.
Samsung Electronics is experiencing the same passive selling pressure as SK hynix due to index fund rebalancing and BlackRock raising cash for SpaceX. The selling is not based on fundamental deterioration. Samsung Electronics will recover after the adjustment phase.

KOSPI level-up supports above 3,000.
KOSPI has broken above its multi-year resistance level around 3,000 in a structural level-up event, similar to the break above 1,000 in the mid-2000s. Historical pattern shows that after such a break, the previous resistance becomes new support, making a fall back to the old range (e.g., 2,000) unlikely. This implies a higher structural floor for the Korean equity market.
