Collect and normalise fundamentals
Extract structured features (ratios, growth rates) from filings and price histories, and normalise by sector and firm size.
Rank stocks by fundamentals. Check similarity-based signals.
A fundamentals ranking engine uses company financial attributes to score and order stocks for investment or screening. Key issues include feature construction from filings, normalising across firms and sectors, handling missing or delayed inputs, and measuring downstream portfolio risk and return.

A proposed decision-support tool for research analysts: surface top candidates by fundamentals for manual review. A human reviewer must remain in charge; this prototype is not for real trading, investment or portfolio-allocation decisions without rigorous backtesting, compliance and operational controls.
Extract structured features (ratios, growth rates) from filings and price histories, and normalise by sector and firm size.
Create a simple scoring model (e.g. weighted linear score or ordinals) with clear preprocessing pipelines and train/test splits.
Assess metrics such as rank correlation (Spearman), return deciles and simulated Sharpe over a backtest window, and inspect failure modes.
Produce an explanation panel showing contributing features, comparable peers and reason codes for each ranked stock.
The supplied starter builds a toy user–item rating matrix from six synthetic ratings, computes cosine similarity between users, finds the most similar user to a target, and recommends items that the neighbour rated but the target has not. It uses pandas pivot_table and sklearn.metrics.pairwise.cosine_similarity and prints three recommended item scores.
matrix = ratings.pivot_table(index="user", columns="item", values="rating").fillna(0)
user_similarity = pd.DataFrame(
cosine_similarity(matrix),
index=matrix.index,
columns=matrix.index,
)
The starter uses synthetic user–item ratings and a nearest-neighbour recommender; it does not load company financials, compute fundamentals-based features, or evaluate stock-ranking metrics. Therefore it does not implement the titled fundamentals ranking task.
Proposed extension: replace the synthetic ratings with a dataset of company fundamentals and market prices, compute standard financial ratios and z-scores, and build a weighted scoring or learning-to-rank baseline with backtested performance.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
