Abstract
This study examines the utility of Grammatical
Evolution in modelling the corporate bond-issuer credit
rating process, using information drawn from the
financial statements of bond-issuing firms. Financial
data, and the associated Standard & Poor's
issuer-credit ratings of 791 US firms, drawn from the
year 1999/2000 are used to train and test the model.
The best developed model was found to be able to
discriminate in-sample (out-of-sample) between
investment-grade and junk bond ratings with an average
accuracy of 87.59 (84.92)% across a five-fold cross
validation. The results suggest that the two
classifications of credit rating can be predicted with
notable accuracy from a relatively limited subset of
firm-specific financial data, using Grammatical
Evolution.
