Finviz is a fast, data-dense platform loved for its stock screener, market heatmap and technical charts. It’s excellent for scanning the market, but it stops at ratios and price action — there’s no intrinsic-value DCF and nothing to track your reasoning over time.
A famously fast screener and a market-wide heatmap that are hard to beat for scanning.
Dense technical charts, news and breadth data all on one screen.
Finviz tells you a stock is cheap on a ratio. Lemma Analysis tells you what it’s worth: a full DCF with your assumptions, margin of safety and scenarios — not just a P/E column.
Reverse DCF converts today’s price into the growth the market is betting on, so a “cheap” screen result gets a real intrinsic-value check before you act.
Beyond the scan, keep a thesis for every holding with a review date, plus portfolio factor, drawdown and correlation analytics Finviz simply doesn’t offer.
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. Lemma Analysis is free to start and adds what Finviz lacks: an intrinsic-value DCF you control, portfolio analytics and a thesis journal, alongside a stock screener.
Finviz is built for scanning and technicals; it has no intrinsic-value DCF, no portfolio factor/drawdown analytics and no thesis journal. Lemma Analysis adds all three so you can value a stock and hold it with discipline, not just find it.
No — Finviz screens on ratios and price action rather than discounted cash flow. Lemma Analysis gives you a full DCF with editable assumptions, scenarios and a reverse DCF.
Yes. Lemma Analysis includes a stock screener; the difference is that a result can flow straight into a DCF valuation and onto a watchlist with a margin-of-safety target.
