ruly Your criteria, applied with discipline, and a record of every decision.
A decision-support tool for individual investors. You pick your criteria and thresholds, you enter your figures, and each criterion gets a verdict. The decision stays yours.
Free for up to 3 sheets, no credit card needed.
- Return on invested capital (ROIC) 18.4% Threshold ≥ 15% Criterion met
- Operating margin 21.0% Threshold ≥ 15% Criterion met
- Net debt / EBITDA 2.6 Threshold ≤ 2 To monitor
- Annual revenue growth (5 years) 3.1% Threshold ≥ 5% Criterion not met
Three steps, always the same
-
Pick your strategy
Start from a preset strategy (long-term quality, growing dividend, value, reasonable growth) or build your strategy criterion by criterion, with your own thresholds.
-
Enter your figures
Take them from the annual report or from your usual data website. No market data is supplied: you know where every number comes from.
-
Read the verdict, note your decision
Each criterion is met, to monitor or not met. You note your decision, “I’m buying”, “I’m watching” or “I’m passing”, then freeze a dated version after each earnings release.
Built for discipline, not for noise
-
Your rules, not an algorithm’s
The verdict applies your criteria and your thresholds. No in-house score, no imposed ranking.
-
A record of every decision
A frozen version keeps the figures and your decision at a given date. You can reread why you decided, one earnings release after another.
-
A dashboard you can read
One row per company, one dot per criterion: compare your sheets at a glance.
-
No ads, no profiling
Your account only knows your email address and your language. No advertising, no resale of data.
-
On all your devices
Your sheets sync across your devices and stay readable offline.
-
In four languages
English, French, German and Spanish, with the number and date formats of your language.
What the tool does not do
It supplies no market data, rates no company and never tells you what to do with a stock. It is a decision-support tool, not investment advice.
