Monthly corporate bankruptcy predictions arrive the 2nd of every month.

Tutorials are the best documentation — Corporate Bankruptcy Tutorial

Input Datasets	SEC Bankruptcies, Delistings, Market Data, Financial Statements
Models Used	CNN, LightGBM, RocketModel, AutoEncoder
Model Outputs	Calibrated Probabilities, Shapley Values

Description

The model predicts the likelihood of bankruptcies in the next 6-months for US publicly listed companies using advanced machine learning models.

With an accuracy of around 89% and ROC-AUC of 85%, these models represent a large improvement over traditional methods of bankruptcy prediction for equity selection.

Advanced modeling techniques used in this dataset:

• The Boosting Model: Utilizes LightGBM technology, integrating both fundamental and market data for accurate predictions.
• The Convolutional Model: Employs a Convolutional Neural Network (CNN) for efficient pattern recognition in market trends.
• The Rocket Model: Specializes in time series data, using random convolutional kernels for effective classification and forecasting.
• The Encoder Model: Combines LightGBM with CNN autoencoders, enhancing feature engineering for more precise predictions.
• The Fundamental Model: Focuses solely on fundamental data via LightGBM, without extra architectural layers, for straightforward financial analysis.

Data Access

Monthly Probabilities

Specific Tickers

import sovai as sov
df_bankrupt = sov.data('bankruptcy', tickers=["MSFT","TSLA","META"])

Specific Dates

import sovai as sov
df_bankrupt = sov.data('bankruptcy', start_date="2017-01-03", tickers=["MSFT"])

Latest Data

import sovai as sov
df_bankrupt = sov.data('bankruptcy')

All Data

import sovai as sov
df_bankrupt = sov.data('bankruptcy', full_history=True)

Daily Probabilities

import sovai as sov
df_bankrupt = sov.data('bankruptcy/daily', tickers=["MSFT","TSLA","META"])

The daily probabilities are experimental, and have a very short history of just a couple of months.

Feature Importance (Shapleys)

import sovai as sov
df_importance = sov.data('bankruptcy/shapleys', tickers=["MSFT","TSLA","META"])

Feature Importance (Shapley Values) calculates the contribution of each input variable (features) such as Debt, Assets, and Revenue to predict bankruptcy risk.

Reports

Sorting and Filtering

import sovai as sov
sov.report("bankruptcy", report_type="ranking")

Filter the outputs based on the top by Sector, Marketcap, and Revenue and bankruptcy risk. You can also change ranking to change to investigate the month on month change.

sov.report("bankruptcy", report_type="sector-change")

When sans_market is positive, it means that the fundamentals show a larger predicted bankruptcy than what the market predicts (stock might go down in medium term) , when sans_market is negative, the market might have overreacted, and predict a larger probability of bankruptcy than what the fundamentals suggest (stock might go up in medium term).
