Using an international Thomson Reuters Datastream database, where size coverage is unusually wide and data errors have been reduced to a low level, we show that some specification decisions, and especially those related to size, may have a significant impact on asset-pricing test results. We...

Investors who want to profitably trade stocks which they believe to be undervalued or overvalued are facing not just transaction costs: also cash constraints and short-selling restriction can hinder them. Intuitively, the more onerous friction may seem to be short-selling: borrowing shares from...

Using a carefully screened and filtered international database with a wide coverage across countries and size classes, this paper identifies and documents a post-1980s size effect which is persistent, not picked up by a Fama–French-style SMB, and largely due to the smallest-decile stocks. We...

Adherents of Fundamental Indexing (FI) suggest that it is more protable to base portfolio weights on indirectly size-related indicators like accounting data rather than directly on market caps. In noisy markets a la Roll (1984), it is argued, underpriced stocks overperform but are underweighted...

To explain convenience yield accruing to commodity inventory holders, time to maturity (TTM) and TIME to harvest should interact with current scarcity. Using weekly data for corn, wheat and soyabeans (1986–2009), the interaction (multiplicative) model performs better than traditional versions...

In this paper we reconsider the estimated deadweight costs for the emerging countries implied by the mean-variance portfolio model developed by Cooper and Kaplanis (1994) and general- ized by Sercu and Vanp¶ee (2007). We show both theoretically and empirically that estimated implicit investment...

Using an international Thomson Reuters Datastream database where size coverage is unusually wide and data errors have been reduced to a low level, we show that some specification decisions, and especially those related to size, may have a significant impact on asset pricing test results. We also...

The Heston-Rouwenhorst (HR) estimates of country and industry factors have been criticised for assuming that each stock has unit exposures to its own country and industry factor. We address this issue analytically and empirically. Our position is that HR are not modeling and estimating a return...
