Delta- Hedging: Comments and a Case in Mathematical Finance

Abstract

The paper questions the ability of arbitrageurs to ascertain value with some confidence and to realize it quickly. The discussion in the paper suggests a reason why some markets are more attractive for arbitrage than others The paper identifies a number of so-called anomalies in which particular investment strategies have may not earn higher returns than their systematic risk. Our analysis offers a different mathematical approach to understanding these anomalies than does the standard efficient market theory.
