Credit Risk Assessment of Corporate Debt using Sentiment and News



A QWAFAFEW discussion led by:


Dan diBartolomeo




Since the Global Financial Crisis of 2007-2009 history has been marked with numerous failings to correctly assess the credit worthiness of financial instruments, financial institutions and governments.   Institutional confidence in the traditional credit rating agencies has been greatly reduced.   One of the largest rating agencies, Standard and Poors, recently agreed to pay a $1.4 billion fine to US regulators for alleged widespread negligence in the ratings of certain complex financial instruments.   As an alternative to the traditional rating process, this work will illustrate the potential use of sentiment statistics from quantified news to calibrate and update the credit risk of corporations and financial institutions in real time.   A modified version of the Merton (1974) contingent claims model from diBartolomeo (2010, 2012) is used to break each corporate debt into two pieces, the first considered riskless debt and the second equity in the issuer.   We utilize news flows and sentiment statistics to frequently update the expected volatility of the assets of the firm and hence the credit risk of the debt in terms of both the probability of default and loss given default.




Mr. diBartolomeo is President and founder of Northfield Information Services, Inc. Based in Boston since 1986, Northfield develops quantitative models of financial markets. The firm’s clients include nearly three hundred financial institutions in twenty countries.


Dan is a Visiting Professor at the CARISMA Research Center of Brunel University in London. In addition, he serves on the Board of Directors of the Chicago Quantitative Alliance and the advisory board of the International Association of Financial Engineers. He is also an active member of the Financial Management Association, and “QWAFAFEW.” He has been admitted as an expert witness in US federal courts and state courts for litigation matters regarding investment management practices and derivatives.


In 2010, Dan received an award from Institutional Investor magazine as one of the forty most influential executives in financial technology in connection with his analytical work that helped uncover the Madoff investment fraud.


Mr. diBartolomeo is a director of the American Computer Foundation, and formerly served on the industry liaison committee of the Department of Statistics and Actuarial Sciences at New Jersey Institute of Technology. He continues his several years of service as a judge in the Moscowitz Prize competition, given by the University of California at Berkeley for excellence in academic research on socially responsible investing. He is also vice-president of the Boston Economics Club, and a regional director of the PRMIA organization.
