We examine the relationship between price limits and stock market volatility. We find when price limits are made more (less) restrictive stock market volatility is usually not lower (higher). This finding contradicts conventional wisdom and the view of most regulators.  2001 Elsevier Science B.V. All rights reserved.

a r t i c l e i n f o Keywords: Price range CARR Financial crisis Smooth transition copula Volatility contagion REIT We use a newly-developed time-varying range-based volatility model to capture the dynamics of securi-tized real estate volatility. The novelty of the model is the use of a smooth transition copula function to capture the nonlinear comovements between major REIT markets in the pre...

A new approach to modelling and pricing derivative securities based on many underlying assets is developed, with the ultimate, practical aim to properly price such derivatives when each underlying shows a volatility smile/skew. We show that the proposed multidimensional model can indeed account for the observed implied volatility smiles for a range of single securities, when each single-asset v...

S tock returns of companies listed on the stock exchange is one of the most important criteria in assessing the macroeconomic. This study investigates the effect of exchange rate Volatility on the stock exchange Returns of D8 countries. It takes monthly data during the period (2008:1-2015:6) constituting 90 observations. At first we used Panel-GARCH model to estimate Exchange Rate Vo...

An Asian option is a path-depending exotic option, which means that either the settlement price or the strike of the option is formed by some aggregation of underlying asset prices during the option lifetime. This thesis will focus on European style Arithmetic Asian options where the settlement price at maturity is formed by the arithmetic average price of the last seven days of the underlying ...

the study attempts to find out the impact of buyback announcement on share price. paired sample t-test is employed to compare share price before and after the buyback announcement. the analysis of variance is also used to find out whether there is any significant difference among industries in the price change due to buyback announcement. the study is carried out from 1st january 2005 to 31st d...

Single index financial market models cannot account for the empirically observed complex interactions between shares in a market. We describe a multi-share financial market model and compare characteristics of the volatility, that is the standard deviation of the price fluctuations, with empirical characteristics. In particular we find its probability distribution is similar to a log normal dis...

The futures market in West Texas Intermediate crude oil was introduced in 1983 with a posted-price cash market in which the posted price changed a few times a year. By 2002, the cash price changed almost daily. Evidence from producers’ invoices shows that this initially low frequency of price changes reflects transactions prices. Using experiments, we show that the introduction of a futures mar...

We use Bayesian Markov Chain Monte Carlo methods to investigate the linkage between the volatility of ethanol security prices and the uncertainty surrounding the profitability of ethanol production and the price variations of non-ethanol energy securities. The joint evolution of return and volatility is modeled as a stochastic process that incorporates jumps in both return and volatility. While...

This thesis examines the performance of five option pricing models with respect to the pricing of barrier options. The models include the Black-Scholes model and four stochastic volatility models ranging from the single-factor stochastic volatility model first proposed by Heston (1993) to a multi-factor stochastic volatility model with jumps in the spot price process. The stochastic volatility ...
