Start with a comparable universe
Choose an available market or fund group before adjusting filters. Rankings depend on that universe and the data available at the time of the scan. Comparing scores across companies with very different coverage or specialist business models can hide more than it reveals. Open the individual report to check those differences.
Example: narrowing a research list
Begin with a broad list, sort by the component relevant to your question, and inspect a few candidates in detail. For a value-oriented search, a valuation score is a starting point; debt, cash generation and coverage can explain why a candidate is risky. Save the names that merit further work and record why, instead of treating the first row as an automatic trade.
Questions about this tool

- Why can rankings change?
- Prices, financial inputs and data coverage change. Compare the report dates and calculation details before interpreting a new position in the ranking.

Methodology, sources and authorship
Astro Trader is developed by Víctor Balcells. The stock model weights valuation (40%), quality and trend (30%), and timing (30%). Risk filters and data coverage accompany the result. Crypto and ETFs have their own models; exploratory cycles do not enter the fundamental stock score.
Market data comes from external providers, including Yahoo Finance; insider evidence links to SEC filings. Consult each report's dates, original sources and coverage: a missing observation is not a confirmed zero. AI text is generated commentary, not a statement written or verified by the author.
