This paper describes a simple yet powerful methodology to decompose asset returns sampled at high frequency into their base components (continuous, small jumps, large jumps), determine the relative magnitude of the components, and analyze the finer characteristics of these components such as the...

We study the effect of country-specific noise on stock price comovement. Using a sample of dual-listed stocks, we show that the effect persists over time for some largest A-shares traded in China, but diminishes quickly for their H-shares traded in Hong Kong. We then examine whether the noise...

In contrast to the efficient-market hypothesis (EMH), the noisy-market hypothesis (NMH) asserts that prices are but noisy indications of fundamental values. We study losses in certainty equivalents of investing according to one hypothesis (NMH or EMH) when the other is true. Our findings suggest...

This paper examines unique cultural features associated with the Japanese calendar known as rokuyo, which classifies days into six categories of varying levels of favorable/unfavorable sentiment days. Prior to the internationalization of Japanese financial markets in the early 1980s, rokuyo has...
