Avoid causal shortcuts
Time-series similarities can arise by chance or shared trends. This exploration is not part of the stock score.
Different series, different clocks
Sunspot observations and financial prices have different frequencies and long-term patterns. Align the periods before comparing them and check whether a visual similarity depends on smoothing or a selected window. A shared rise or fall does not by itself establish a mechanism connecting solar activity with market returns.

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.
