We examine the performance of the buy-write option strategy (BWS) on the Australian Stock Exchange and analyse whether such an investment opportunity violates the efficient market hypothesis on the basis of its risk and returns. This study investigates the relationship between buy-write...

We consider a model where investors can invest directly or search for an asset manager, information about assets is costly, and managers charge an endogenous fee. The efficiency of asset prices is linked to the efficiency of the asset management market: if investors can find managers more...

We argue that the Jacobsen and Visaltanachoti (2009) study is incomplete. Jacobsen and Visaltanachoti (2009) evaluate the Halloween effect or ‘Sell in May'-effect as documented by Bouman and Jacobsen (2002), and extend the analysis into the relative performances of sectors during the winter...

We investigate how security specific mispricing may persist under limits to arbitrage; specifically, when arbitragers are limited by the availability of substitutes and financial constraints. We use a part of the market to book decomposition as a proxy for mispricing. The availability of...

Theory has linked price momentum with price reversals (Barberis, Shleifer, and Vishny (1998), Daniel, Hirshleifer, and Subrahmanyam (1998), and Hong and Stein (1999)). The models generally rely on behavioral descriptions of irrational investors who push prices beyond their fundamental value thus...

We explore the link between stock returns and changes in market capital concentration across firms. Our theory uncovers a concentration risk factor driven by time-varying changes in the distribution of market capital. A powerful implication of our theory is the necessary existence of this...

The past several years have witnessed the introduction of hundreds of so-called “smart beta” equity indices. These indices provide exposure to risk factors, such as value or low volatility, in order to seek excess return and/or risk reduction compared to cap-weighted indices. Although the...
