Frequently asked questions
Is Market Lens really a free Simply Wall St alternative?+
Yes. The full workflow — a Buffett-style quality score, a DCF fair-value estimate, fundamentals, and a plain-English AI summary — is free, with no account required. Paid research platforms typically charge a monthly or annual subscription for a comparable feature set.
What does Market Lens do that a typical research dashboard does not?+
It shows its homework. Instead of only a summary score, Market Lens walks through the four Buffett criteria and the DCF assumptions so you can see why a number came out the way it did. It also includes a congressional-trade tracker.
What is the Buffett-style score based on?+
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). See the Methodology page for the full breakdown.
Is this investment advice?+
No. Market Lens is educational research. It shows you the analysis and the reasoning; the decision is always yours. It scores stocks against a rules-based checklist and labels them Meets criteria, Watch, or Fails criteria. It does not tell anyone to buy or sell, it does not predict prices, and it is not investment advice.
