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...

Alexander Izmailov, Ph.D (theoretical physics) and Brian Shay, Ph.D (mathematics), of Market Memory Trading, L.L.C., present in a series of nine (9) white papers, aspects of a revolutionary advance in uncovering hidden dependencies via filtering noise from correlation matrices developed by the...

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...

Volatility is an important component of asset pricing; an increase in volatility on markets can trigger changes in the risk distribution of financial assets. In conventional financial theory, investors are considered to be rational and any changes in relevant risk are assumed to be a result of...

Lower skill of the active management industry can imply greater fee revenue, value added, and investor performance. Such outcomes arise in a competitive equilibrium in which portfolio choices of active managers partially echo those of noise traders and also contain manager-specific noise. Both...

We introduce the information microstructure of a canonical noisy rational expectations model (Hellwig, 1980) into the framework of a conventional real business cycle model. Each household receives a private signal about future productivity. In equilibrium, the stock price serves to aggregate and...

This paper utilizes a new dataset of foreign and domestic mutual funds in Mexico to assess their behavior and obtains three new findings. First, foreign mutual funds are more sensitive to global financial conditions and engage more in herding and positive feedback trading than domestic mutual...

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...

Whether lower stock price synchronicity reflects information or noise does not have a conclusive answer yet. From the perspective of analyst following in China, our empirical study reveals that, the stock price synchronicity which star analysts following is lower than that of non-star analysts,...
