Yahoo Finance is the familiar free home for quotes, news, watchlists and broad market data. It’s great for a quick look, but it’s built for breadth, not depth — there’s no intrinsic-value DCF, and the portfolio analytics stop at the basics.
Free, familiar and enormously broad — quotes, news and data on almost anything.
Quick watchlists and portfolios that anyone can set up in seconds.
Yahoo shows a price and a P/E; Lemma Analysis shows what a stock is worth — a full DCF with your assumptions, margin of safety and scenarios.
No banner ads or clutter — a purpose-built terminal for valuing companies, screening and tracking a portfolio with real factor and drawdown analytics.
A thesis journal with review dates keeps you honest about why you own each position — something a quotes page will never do.
Sign up in a moment — no credit card. Everything below is included on the free plan.
Open any ticker and the DCF is pre-filled from years of financials. Change any assumption and fair value, margin of safety and the sensitivity grid update live.
Screen for candidates, then track them on a watchlist with a margin-of-safety target so each name carries an undervalued / fair / rich signal.
Record why you own each position and give it a review date. Reaffirm or exit when the date comes due — a habit the other tools don’t give you.
Yes — it’s free to start. The difference is depth: an intrinsic-value DCF, real portfolio analytics and a thesis journal instead of just quotes and news.
Yahoo Finance has no intrinsic-value DCF, only basic portfolio analytics and no thesis journal. Lemma Analysis adds an editable DCF with reverse DCF and scenarios, factor/drawdown analytics, and a journal to track why you hold each position — in an ad-free workspace.
No — it shows ratios and price data rather than a discounted cash flow model. Lemma Analysis gives you a full, editable DCF pre-filled from years of financials.
Yes — build watchlists in Lemma Analysis and set a margin-of-safety target on each, so every name carries an undervalued / fair / rich signal against your fair value.
