This paper examines the holiday effect presence of on the Romanian stock market. We perform regressions with dummy variables and daily values of some from the main indexes of the Bucharest Stock Exchange. The results indicate a post-holiday effect for all the indexes and a pre-holiday effect...

This paper investigates the existence of the monthly effects on the Romanian Stock Exchange. We employ the returns of the main indices and the trading volume and the trading values from the main components of the Bucharest Stock Exchange. We find different forms of monthly seasonality...

The paper presents a measure of the intertemporal cross correlation between two time series and reports evidence of the presence of intertemporal cross dependence between the returns of NYSE stocks and those of the SP 500, showing that frequently traded stocks behave differently from stocks with...

A fast and accurate method for pricing early exercise and certain exotic options in computational finance is presented. The method is based on a quadrature technique and relies heavily on Fourier transformations. The main idea is to reformulate the well-known risk-neutral valuation formula by...

We present a pricing method based on Fourier-cosine expansions for early-exercise and discretely-monitored barrier options. The method works well for exponential Levy asset price models. The error convergence is exponential for processes characterized by very smooth transitional probability...

Here we develop an option pricing method for European options based on the Fourier-cosine series, and call it the COS method. The key insight is in the close relation of the characteristic function with the series coefficients of the Fourier-cosine expansion of the density function. In most...

This paper explores the relation between the prices and the trading volume from the Bucharest Stock Exchange. The data employed consist in the daily values from January 2002 to March 2011. We identify some significant changes caused by events such as Romania’s adhesion to the European Union or...

The systematic risk is considered as one of the most important factors that influence the investment in financial assets. Usually, it is evaluated in the framework of the Capital Asset Price Model. The systematic risk associated to firm equities is affected by some firm’s characteristics,...

The paper examines and explains why estimates of systematic risk (beta coefficient) shift the time-interval used to measure returns changes
