Different share classes on the same firms provide a natural experiment to explore how investor clienteles affect momentum and short-term reversals. Domestic retail investors have a greater presence in Chinese A shares and foreign institutions are relatively more prevalent in B shares. These differences result from currency conversion restrictions and mandated investment quotas. We find that only B shares exhibit momentum and earnings drift and only A shares exhibit monthly reversals. Institutional ownership strengthens momentum in B shares. These patterns accord with a setting where short-term reversals (which represent inventory risk premia) prevail in a market dominated by noise traders and momentum prevails in markets where noise traders are less prevalent relative to informed investors who underreact to fundamental signals. Overall, our findings confirm that clienteles matter in generating stock return predictability from past returns.

This study investigates how Schwartz’s cultural dimensions of embeddedness and mastery affect the corporate cost of debt through bankruptcy risk and sensitivity to agency activity channels. Using data from 33 countries, we find a strong and robust negative relation between embeddedness and the cost of debt. The estimated relation between mastery and the corporate cost of debt is negative and significant in most of the tests. Further analyses reveal that the development of financial intermediation and the enforcement of insider trading law moderate the relation between culture and the cost of debt. Confirming our hypotheses, we document that embeddedness is negatively related to bankruptcy risk and sensitivity to agency activity. We find that mastery is positively related to bankruptcy risk across countries as well, but this relation is weaker. We also show that mastery is positively related to sensitivity to agency activity among countries with highly leveraged firms.

We examine how societal secrecy affects the underpricing of initial public offerings (IPOs). Using a large sample of 18,304 IPOs across 38 countries, we find robust evidence that IPO underpricing is positively related to societal secrecy. Additional analyses reveal that investor protection, market openness, and third-party certification moderate the effect of societal secrecy on IPO underpricing. We find that societal secrecy influences IPO underpricing through the information asymmetry, demand for control, and information cascade channels. Collectively, we show that societal secrecy exerts a strong influence on IPO underpricing globally.

ABSTRACT This paper examines how cultural differences influence the returns of momentum strategies. Cross‐country cultural differences are measured with an individualism index developed by Hofstede (2001) , which is related to overconfidence and self‐attribution bias. We find that individualism is positively associated with trading volume and volatility, as well as to the magnitude of momentum profits. Momentum profits are also positively related to analyst forecast dispersion, transaction costs, and the familiarity of the market to foreigners, and negatively related to firm size and volatility. However, the addition of these and other variables does not dampen the relation between individualism and momentum profits.
