Collect and label corpus
Assemble a timestamped corpus of financial news or filings with clear labelling rules (directional or continuous) and keep a held-out validation period.
Analyse financial news sentiment. Judge sentiment impact cautiously.
Financial-news sentiment analysis aims to score news items by directional tone (positive, negative, neutral) and to flag language that could affect investment or compliance decisions. Label quality, temporal drift, market-event correlation and ambiguous language are common challenges.

Financial-news sentiment analysis aims to score news items by directional tone (positive, negative, neutral) and to flag language that could affect investment or compliance decisions. Label quality, temporal drift, market-event correlation and ambiguous language are common challenges.
A proposed application: a dashboard that highlights potentially market-moving headlines and presents human-review reasons and links to source text. This extension is not implemented in the supplied starter.
Assemble a timestamped corpus of financial news or filings with clear labelling rules (directional or continuous) and keep a held-out validation period.
Train a TF-IDF plus logistic-regression baseline, using only training text to build vocabulary and preserving class balance strategies for rare labels.
Report precision, recall and F1 per class and inspect examples around major market events and ambiguous language for systematic errors.
Design a human-in-the-loop review panel, monitoring drift and adding auditing, latency and privacy safeguards before any automated decision use.
The supplied starter builds a small scikit-learn pipeline: it defines six short, generic English sentences with binary labels, splits them into train and test sets, fits a TF-IDF vectoriser plus LogisticRegression, prints a classification report on the tiny test split, and shows one sample prediction. The data are not financial news and do not validate a financial sentiment model.
model = Pipeline(
steps=[
("tfidf", TfidfVectorizer(ngram_range=(1, 2), min_df=1)),
("classifier", LogisticRegression(max_iter=1000)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)The starter uses six handcrafted, non-financial sentences and binary labels; this is not representative of financial-news text, events or label granularity. The tiny test split cannot support meaningful performance claims and the code lacks timestamp handling, deployable I/O, calibration, or drift monitoring required for finance use.
A proposed extension: collect a labelled, timestamped corpus of financial headlines and filings, train a TF-IDF and transformer-embedding ensemble, and surface predictions in a review dashboard that records human adjustments and timestamps for drift analysis.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
