Pricing Of Idiosyncratic Risk In An Intermediary Asset Pricing Model, Hasib Ahmed
Pricing Of Idiosyncratic Risk In An Intermediary Asset Pricing Model, Hasib Ahmed
University of New Orleans Theses and Dissertations
Standard asset pricing theories suggest that only systematic risk is priced. Empirical studies report a relationship between idiosyncratic volatility or risk (IVOL) and asset price. The most common explanation for this anomaly is that households under-diversify creating a Bad Model problem. This paper uses an Intermediary Asset Pricing Model (IAPM) as a way to control for under-diversification in evaluating the relationship between IVOL and asset price. We find that IVOL premia is lower in an IAPM. Our findings indicate that under-diversification can explain the anomaly partially.
