This paper compares option pricing models, based on the Black model (Black, 1976), with particular emphasis on volatility measures and estimators applied in the process of valuation. We calculate the Black model with historical (BHV), implied (BIV) and several different types of realized (BRV)...

The main idea of this research is to check the efficiency of the Black option pricing model on the basis of HF emerging market data. However, liquidity constraints - a typical feature of an emerging derivatives market - put severe limits for conducting such a study. That is the reason why we...

Option pricing models are the main subject of many research papers prepared both in academia and financial industry. We check the properties of option pricing models with different assumptions concerning the volatility process (historical, realized, implied, stochastic or GARCH model). For this...

The ad hoc Black-Scholes (AHBS) model is one of the most widely used option valuation models among practitioners models. The main contribution of this study is methodological. We have two main results: (1) we make the empirical observation that typically the call and put sneers are discontinuous...

In this article the relationship between market return and volatility is examined by applying out-of-sample methodology and ARCH (M) class models in the Tehran Stock Exchange (TSE) and international stock exchanges. The results are inconsistent with portfolio theory implications in NASDAQ, ISE...

Based on a method developed by Laybourne, Kim and Taylor (2007) for detecting multiple changes in persistence, we test for changes in persistence in the dividend-price ratio of the Nasdaq stocks. The results confirm the existence of the so-called Dotcom bubble around the last turn of the century...

In this paper, we compared several Black option pricing models by applying different measures of volatility and examined the Black model with historical (BHV), implied (BIV), and several different types of realized (BRV) volatility. The main objective of the study was to find the best model;...

Purpose of this paper - The current paper aims to analyze the impact of the debt crisis on the FTSE/ASE 20 index volatility. The research also examines the impact of powerful foreign capital markets on the Greek Stock Exchange market, the seasonality returns (Day-of-the-Week effect) and the...

In this paper, we examine the behavior of the intra-daily stock returns and close-end stock price manipulation in the Istanbul Stock Exchange (ISE). Understanding the price behavior in a given trading day could help investors when they are making their buy and sell decisions. Studies of...

Using daily data of four currencies (Japanese yen, euro, British pound, and Australian dollar) in terms of the U.S. dollar, and these four currencies in terms of the euro from January 2004 to February 2008, we examine the lead-lag relationship between the credit default swap (CDS) market and the...
