Abstract
This paper examines the capabilities of the Normal Inverse Gaussian
distribution as a model for stock returns. We extend the model of
Barndorff-Nielsen (1997) to allow for a richer volatility structure and compare
with the existing GARCH-type models. We conclude that the proportional model
outperforms some of the most praised GARCH-M models. In particular, we make a
big gain in modelling the skewness of equity returns
