Valuation, quality and timing
The quantitative model weights valuation at 40%, quality and trend at 30%, and timing at 30%. Risk filters take precedence over the final number.

Coverage before confidence
Missing inputs are excluded from measured points. Low coverage pulls a pillar towards neutral; critical gaps and specialist sectors can leave a stock unrated.
Cash flow and solvency
Review free cash flow, enterprise value, net debt and interest coverage. FCF/EV is a screening approximation using levered free cash flow, not a full valuation model.
Verified insider activity
Consult SEC filings, eligible purchases, independent buyers and excluded or unverified transactions. Zero eligible purchases is not proof of no activity.
Read the score and the coverage together
The stock report combines three pillars: valuation at 40%, quality and trend at 30%, and timing at 30%. Within each pillar, available metrics are assessed against explicit thresholds. Missing inputs reduce coverage and the measured result is adjusted towards neutral. This is not evidence that missing figures are healthy. Critical gaps or unsuitable sectors can leave the company unrated.
Example: a cheap-looking business with weak cash flow
Suppose a company looks inexpensive relative to earnings but has negative operating cash flow and high debt. Open the free-cash-flow, debt and interest-coverage details before interpreting its total score. FCF/EV uses levered free cash flow as a screening approximation; it is not a discounted cash-flow valuation. A risk filter can take precedence even when another pillar looks attractive.
What insider evidence can tell you
The insider section separates SEC documents, transaction facts and interpretation. It distinguishes eligible purchases, reported sales, independent buyers and excluded or unverified operations. A result of zero eligible purchases can reflect the selected window, coverage or eligibility rules. Read the filing before inferring conviction, and do not assume a sale is meaningless.
Questions about this tool
- Where does the stock data come from?
- Market and company inputs include Yahoo Finance data; insider verification uses SEC filings. The web application fetches data through its server. Dates, gaps and source coverage matter, especially for small companies and non-US listings.
- Does a high score mean I should buy?
- No. The score summarises the model's inputs and assumptions. Check coverage, mandatory risk filters, sector fit and the original accounts before using it in your own research.
- Does AI change the quantitative score?
- No. AI supplies a separate qualitative interpretation of risks, products, catalysts and narrative. It can challenge the reading without rewriting the calculated score.

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.
