Buffett-style quality score (0–100)
Every stock is rated on the four criteria Warren Buffett is known for — circle of competence, moat, a fortress balance sheet, and margin of safety — with the reasoning shown, not hidden.

A discounted-cash-flow estimate with bear, base, and bull scenarios and a Gordon-growth terminal value, so you can see whether the current price looks cheap or expensive.
Valuation & intrinsic value
P/E, P/B, Graham Number (where it applies), and an averaged intrinsic-value estimate — the classic value-investing yardsticks in one place.
Peer comparison
See how the company stacks up against its closest competitors on growth, margins, and returns on capital.

Revenue, earnings, debt, cash, and returns on invested capital — the numbers that tell you how the business is really doing.
Plain-English AI deep-dive
A plain-English written summary that explains what the business does, where its edge is, and what the risks are — in language anyone can follow.

How is the Buffett score calculated?+
It blends four sub-scores (each 0–10) with fixed weights into a 0–100 composite: circle of competence 25% (a sector and industry lookup), moat 30% (margins, return on equity, revenue growth, and company size), financial strength 25% (debt-to-equity, current ratio, and cash flow), and margin of safety 20% (price versus an intrinsic estimate built from the Graham Number and a fair-P/E value).
