Stock Rover is a powerful research tool with deep fundamental screening, strong portfolio analytics and fair-value estimates. It’s one of the closest tools to what we do — but it lives in a dense, dated desktop-style interface, and it has no place to record your thesis.
Very deep fundamental screening across a huge library of metrics.
Strong portfolio analytics and research reports for serious US investors.
The same analytical depth without the dense, dated learning curve — a clean terminal you can actually move through quickly, in light or dark.
Go past a static fair-value figure: edit the DCF assumptions, compare bear/base/bull scenarios, and reverse the model to see the growth the price assumes.
Record why you hold each position and give it a review date — a discipline layer Stock Rover’s analytics don’t include.
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 offers similar depth (screener, portfolio analytics, valuation) in a modern, faster interface, adds a reverse DCF and a thesis journal, and is free to start.
Two things stand out: a reverse DCF that shows the growth priced into a stock, and an investment thesis journal with review dates. It also runs in a modern light/dark interface rather than a dense desktop-style one.
Stock Rover’s screener is genuinely deep and we don’t pretend otherwise. Lemma Analysis covers fundamental screening too, and connects it to a DCF valuation and a thesis journal so a screen result flows into a decision.
Yes — Lemma Analysis is free to start with no credit card, including the DCF, screener, portfolio analytics and journal.
