The paper is the first to evaluate the dividend tax clientele hypothesis using a data set of all domestic stock portfolios in the market. We find that investment funds that face a higher effective tax rate on dividend income than on capital gains tilt their portfolios away from dividend-paying stocks. These investors consequently earn a dividend yield that is about 35 basis points lower than that of investors who are tax neutral between dividends and capital gains (pension funds, unit-linked insurance, life insurance). Consistent with tax rules and charter provisions, we also find that private corporations prefer growth stocks, that foundations exhibit strong dividend preferences, and that partnerships rarely hold stocks portfolios. © 2014 Elsevier B.V.

We study a large data set of stock portfolios held by individuals and organizations in the Swedish stock market. The dividend yields on these portfolios are systematically related to investors' relative tax preferences for dividends versus capital gains. Tax-neutral investors earn 40 basis points higher dividend yield on their portfolios than investors which face higher effective taxation of dividends than capital gains. We conclude that there are dividend tax clienteles in the market. We also argue that the abundant portfolio holdings by closely-held corporations, despite triple taxation at a combined marginal tax rate as high as 77.5%, is a consequence of taxation.

In this paper, we characterize foreign ownership using a dataset of ownership and attributes of Swedish firms. The analysis reveals that foreigners show a preference for large firms, firms paying low dividends, and firms with large cash positions on their balance sheets. When we further analyze the preference for large firms, we find that market liquidity and presence in international markets, measured through export sales or listings on other exchanges, seem to characterize foreign holdings better than firm size alone. Foreigners also tend to underweight firms with a dominant owner. Importantly, we demonstrate that most of the features associated with foreign ownership are driven by the fact that foreign investors typically are mutual funds or other institutional investors. Hence, we identify an institutional investor bias rather than a foreign investor bias. Finally, using ownership data on a country level, we conclude that the results are particularly strong among U.S. investors, who comprise the largest institutions among foreign investors.

This thesis consists of four essays on topics relating to the fields of international portfolio choice, trading behavior, and asset pricing. "Direct Foreign Ownership, Institutional Investors, and Firm Characteristics" analyzes portfolios of Swedish stocks held by foreign investors. The analysis reveals that foreigners tilt their portfolios to firms with certain attributes. It is also shown that the seemingly specific preferences of foreign investors are driven by the fact that they are large institutional investors, and are not linked to their national origin. "Foreigners' Trades in Risky Assets: An assessment of Investment Behavior and Performance" analyzes foreigners' trading activities. It is shown that foreigners trade more than domestic investors. Further, they trade as non-informed trend followers in that they buy stocks that have recently done well. Nonetheless, after the liberalization of Sweden's stock market, foreigners' purchases have led to a permanent price increase and to a reduction in the cost of equity capital. "Exchange Rate Exposure, Risk Premia, and Firm Characteristics" shows that about fifty percent of Swedish listed firms are affected by exchange rate fluctuations. The sign and magnitude of exchange rate exposure are characterized across industries as well as firm attributes. The empirical analysis suggests that exposure can be eliminated through diversification, and that exchange rate risk is not priced. "Conditioning Information in Tactical Asset Allocation" examines whether investors can exploit the predictability in time-varying expected returns on Swedish stocks and bonds. It is shown that dynamic allocation strategies, based on conditioning information, significantly outperform several benchmark portfolios. This superior performance is not only statistically significant, it is economically large.
