Garbade and Silber (1979) demonstrate that an asset will be liquid if it has (1) low price volatility and (2) a large number of public investors who trade it. Although these results match nicely with common notions of liquidity, one key element is missing: liquidity also depends on (3) an asset...

The determination of trends and prediction of stock prices is one of the main tasks of the MACD (Moving Average Convergence Divergence) and the RVI (Relative Volatility Index) indicators of the technical analysis. The research covers the sample representing stocks which are continually traded on...

This study aims to verify whether there are any macroeconomic variables that have significant power in predicting the dynamics of financial markets. In particular, we want to identify an econometric model that can guide the strategies of operators in building their investment portfolios. The...

We show that three proxies for stock price informativeness, adjusted probability of information based trading (AdjPIN), price non-synchronicity and probability of information-based trading (PIN), decrease significantly due to an enlarged investor base after stock splits. The results are...

The battle between proponents of the Efficient Markets Hypothesis and champions of behavioral finance has never been more pitched, and little consensus exists as to which side is winning or the implications for investment management and consulting. In this article, I review the case for and...

In this paper, a result for bivariate normal distributions (Sheppard, 1899) from statistics is transformed into a financial asset context in order to build a tool which could translate a correlation matrix into an equivalent probability matrix and vice versa. This way, the correlation...

In this paper I build a continuous time model of a complete financial market with $N$ heterogeneous agents whose constant relative risk aversion (CRRA) preferences differ in their level of risk aversion. I find that preference heterogeneity is able to replicate a high market price of risk and a...

Classical quantitative finance models such as the Geometric Brownian Motion or its later extensions such as local or stochastic volatility models do not make sense when seen from a physics-based perspective, as they are all equivalent to a negative mass oscillator with a noise. This paper...

Learning the pre limited liability value process of equity claims and its relationship to the stock price is an answer to the financial jeorpardy question when observed option prices are the answer being given by the market. Constant dollar equity holder values, prior to the imposition of...

In this paper we look into the interaction of Google's search queries and several aspects of international equity markets. Using a novel methodology for selecting words and a VAR modeling approach, we study whether the search queries of finance related words can have an impact on market...
