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

Canadian project asymmetric upside for Hanwha Ocean
The Canadian CPSP project decision expected this month offers asymmetric upside for Hanwha Ocean. If awarded, it could fill roughly two years of special ship orders at once, while failure does not disrupt the strong earnings trend. The risk/reward is skewed to the upside.

AI data center engine orders boost HD Hyundai Heavy
HD Hyundai Heavy's engine machinery division has secured an order for 20MW gas engines for data centers, representing about 7% of annual capacity. This links shipbuilding to AI power demand and could drive expansion and re-rating if data center orders grow.

Shipbuilding upcycle not over, buy leaders.
Korean shipbuilders hold record order backlogs stretching to 2027–2028, with ship prices remaining high and no sign of a peak. New catalysts include the potential Canadian submarine project, which could fill two years of naval vessel orders for Hanwha Ocean, and data center power generation engine contracts for HD Hyundai Heavy Industries. HD Korea Shipbuilding & Offshore is deeply undervalued as a holding company, trading at a large discount to the sum of its listed and unlisted assets plus high dividend yield.

HD Korea Shipbuilding deeply undervalued high dividend
HD Korea Shipbuilding & Offshore Engineering is extremely undervalued. The market cap is largely explained by its stake in HD Hyundai Heavy alone, ignoring unlisted subsidiaries and cash. Its dividend yield is about double that of HD Hyundai Heavy, and DPS can rise further as earnings grow towards 2027-28, making it a safe high-dividend pick.

Long power transformer stocks for structural demand.
The power equipment sector is driven by structural demand from AI data center expansion, reshoring, renewable energy integration, and aging grid replacement. The three transformer makers (LS Electric, Hyosung Heavy Industries, HD Hyundai Electric) have strong order pipelines, quality and delivery advantages, and their valuations are attractive after the recent pullback. Yoo recommends buying on dips with a long-term horizon, as the fundamentals remain intact and the medium-to-long-term outlook is robust.
