DUEL
Pairwise fundamental scores for two US stocks
What it is
An open Python routine that scores two US-listed companies against each other on eight fundamentals taken from SEC EDGAR filings. Revenue growth, margins, cash flow, return on capital, asset turnover, accrual quality, and leverage become one relative score based on how wide the gap is, and separate consistency checks point out tensions without changing the score. Fundamental investors and researchers who want a transparent head-to-head on official filings are the audience. Only that base comparison is published, as a hand-checked snapshot rather than a scheduled download, and the resilience and valuation reports stay unpublished.
