Define the task and labels
Decide whether you predict drawdown, VaR exceedance, default, or a binary risk flag and assemble corresponding historical labels.
Analyse portfolio risk. Quantify decision impact.
Portfolio risk analysis translates portfolio inputs (prices, exposures, positions) into measures that help decisions such as rebalancing or hedging. Key practical issues are realistic labels, time-series train/test splits, transaction costs, and model monitoring for drift and data quality.

Portfolio risk analysis translates portfolio inputs (prices, exposures, positions) into measures that help decisions such as rebalancing or hedging. Key practical issues are realistic labels, time-series train/test splits, transaction costs, and model monitoring for drift and data quality.
A proposed application: provide near-term risk scores and scenario summaries to portfolio managers so they can prioritise human review. Because this domain affects real money, any automated score should be shown alongside human-reviewed explanations and not used without governance and a compliance process.
Decide whether you predict drawdown, VaR exceedance, default, or a binary risk flag and assemble corresponding historical labels.
Build rolling-window features from returns, exposures and macro indicators and ensure train/test splits respect chronology to avoid leakage.
Fit a simple pipeline (scaling and a classifier or regressor) to establish a reproducible baseline and log metrics such as MAE, AUC or realised drawdown.
Check performance by horizon and instrument, test scenarios for tail events, and plan monitoring for drift, missing inputs and latency.
The supplied starter creates a synthetic binary classification dataset via sklearn.datasets.make_classification, builds a StandardScaler + RandomForestClassifier pipeline, fits it on the synthetic features, and prints a sklearn classification_report. It does not load financial data, compute portfolio returns, or implement financial risk metrics.
model = Pipeline(
steps=[
("scale", StandardScaler()),
("classifier", RandomForestClassifier(n_estimators=250, random_state=RANDOM_STATE)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)The code uses purely synthetic classification data and arbitrary labels from make_classification; it therefore cannot be used to assess portfolio risk on real instruments. There is no time-series handling, no financial features (returns, exposures, prices), and no economic risk metrics such as VaR or drawdown.
A proposed extension: replace the synthetic dataset with historical positions, returns and market factors; label events such as large drawdowns or constraint breaches and retrain the baseline pipeline using time-aware splits.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
