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

Mercantil cheap, elderly banking growth.
Banco Mercantil focuses on elderly clients (50+), won the latest INSS auction, and has a unique branch-based distribution. It trades at low multiples (4x earnings with 40% ROE), has strong growth from healthcare-assistance products (Meu Mais), and is undervalued due to low liquidity. Management is excellent.

Inter oversold, bought after drop.
Banco Inter sold off 15% on earnings and another 7% on Investor Day due to credit quality concerns and a change in guidance (60/30 to rule-of-50). We saw that as overdone and bought shares this morning. The bank has strong growth potential, conservative provisioning on payroll loans, and a path to 18% ROE in the short term.

Randon sum-of-parts discount, cyclical recovery.
Randon is a conglomerate with heavy leverage and cyclical headwinds, but its sum-of-parts valuation is compelling: Frasle stake alone is worth more than market cap, and the consortium business alone has high value. Operating improvements are underway, and when the cycle turns, earnings can multiply. Patient holders should be rewarded.

Intelbras security growth, margin expansion.
Intelbras has recovered from past capital allocation mistakes in solar energy. Now focused on security (monitoring, cameras, locks) where it has a strong market position. Revenue is growing 11% annually with expanding margins. The stock has performed well YTD and remains a quality small cap with predictable cash flows.

Lavvi cheap, high-end builder.
Lavvi is a high-end homebuilder in São Paulo with excellent management and a strong land bank. After a 30-40% drop in share price, we initiated a position. The company has a large contracted backlog (R$2bn) and high REF margins, indicating significant future revenue and earnings growth. It fits our concentrated small-cap strategy.

Priner growth, mining capex tailwind.
Priner is a services company focused on mining (yellow line equipment operation and assembly). Recent acquisitions (Real, CMEP) have transformed it. Revenue should reach R$2.2bn this year with strong EBITDA margin expansion thanks to operational leverage. The company generates enough cash to reinvest, and net profit could grow 70-80% YoY. It trades at an attractive multiple for a high-growth small cap.

Technos quality, operational leverage.
Technos is a watch retailer with 30% market share in Brazil. It has delivered strong revenue growth (volume and price), expanding gross margins, and operational leverage (SG&A/revenue declining). It is nearly net cash, pays dividends, and buys back shares. The weak dollar helps import costs. Q1 EBITDA grew 15% YoY. A high-quality small cap.

Vulcabras undervalued, high dividend potential.
Vulcabras has a strong brand in athletic footwear, growing double-digit volume and price thanks to performance shoes and e-commerce. Net profit fell due to higher financial expenses after paying dividends, but cash generation remains high. At current prices, the dividend yield could reach 12% next year. The stock is down 23% YTD, offering a good entry.
