Kamstra et al. (2003, 2009, 2012) offer a seasonal affective disorder hypothesis to explain variations in the daily returns of stock indices. We examine Kamstra et al. (2012) new variable called SAD onset/recovery. The analysis reveals concerns for the validity of the SAD hypothesis.

We show that the endogenous stochastic process of the liquidity of securities is as important to investment and valuation as the exogenous stochastic process of their cash flows. We develop a general-equilibrium model with heterogeneous investors who have an every-day motive to trade and pay...

This paper aims to extend the existing literature on foreign exchange rate risk pricing. Unlike the existing studies on Canada, we use six alternative bilateral and one multilateral exchange rate proxies. Furthermore, using both a two-factor and a three-factor capital asset pricing model (CAPM),...

In a perfectly liquid market, investors’ optimal allocation decisions refer to maximizing all three dimensions of liquidity, namely immediacy, width and depth. To the extent that investors fail to accommodate size (depth) along with price (width) in their optimal allocation decisions, their...

Unlike the U.S. and most developed countries, Taiwan stock market has been widely documented to have no value premium. Prior studies on the value premium typically adopt a conventional approach proposed by Fama and French (1992), which suggests a buy-and-hold strategy with annual rebalancing. We...

This paper uses the betas of book-to-market portfolios as proxies for systematic risks of industries instead of the individual betas computed from individual time-series regressions. Our empirical specification improves both the precision of the beta estimates and the cost of equity estimates....

Using eight measures of liquidity, and addressing the potential endogeneity of initial returns, we find underpricing generally increases the secondary market liquidity of IPOs over the first year of trading, irrespective of the horizon over which liquidity is measured. For two model...

We analyze a model of informed trading where an activist shareholder accumulates shares in an anonymous market and then expends costly effort to increase the firm value. We find that equilibrium prices are affected by the position accumulated by the activist, because the level of effort...

We demonstrate that the estimates of the Capital Asset Pricing Model (CAPM) parameters significantly differ across samples, which are based on different days of the week (representing different seasons). Our evidence suggests that the “noise” in the data is not an issue. We also show that...

This paper demonstrates that the factors based on typical procedures that employ sorting by characteristics (including size and book-to-market, among others) can create a good mechanical fit in the regressions of portfolio returns. Such factors are approximately linear functions of the sorted...
