Substituting a Substitute Currency – The Case of Estonia
2002
This study evaluates substitution of foreign currency balances in Estonia, a transition economy neighbouring countries participating in EMU. The focus is on substitution between dollar and euro balances in the three basic functions of money - unit of account, store of value and means of payment. While traditional models for currency substitution concentrate on substitution between a domestic currency and aggregate foreign currency balances, we look for substitution between the dollar and the euro or euro-related foreign currency balances. We find substitution between dollarization and euroization to be asymmetric in the short run, which suggests that inertia, irreversibility and ratchet eff…
European Natural Gas Seasonal Effects on Futures Hedging
2015
Abstract This paper is the first to discuss the design of futures hedging strategies in European natural gas markets (NBP, TTF and Zeebrugge). A common feature of energy prices is that conditional mean and volatility are driven by seasonal trends due to weather, demand, and storage level seasonalities. This paper follows and extends the Ederington and Salas (2008) framework and considers seasonalities in mean and volatility when minimum variance hedge ratios are computed. Our results show that hedging effectiveness is much higher when the seasonal pattern in spot price changes is approximated with lagged values of the basis (futures price minus spot price). This fact remains true for short …
MARKET CORRELATION, MARKET RETURNS AND PORTFOLIO IMPLICATION
2012
In this paper we examine the market correlation and market returns from Romanian perspective. Market returns are higher in emerging markets than developed market returns, but form portfolio perspective it`s also important to evaluate how much correlations are changing in emerging markets. Our results are important in allocation of financial instruments in institutional portfolio management.
Performance and international investments in microfinance institutions
2013
Preprint of the published version of an article from Strategic Change Using data from 319 microfinance institutions (MFIs) in 68 developing countries, we study the degree to which international debt investments are related to the financial and social performances of MFIs. We find that commercial investments are mainly related to financial performance and level of professionalisation of the MFIs. The targeting of women is not a priority, even though international commercial investors target MFIs that provide small loans. Subsidised investments, however, are mainly driven by the targeting of women, while financial performance and the level of professionalisation of the MFI is not a priority.
European Option Pricing and Hedging with Both Fixed and Proportional Transaction Costs
2003
Abstract In this paper we provide a systematic treatment of the utility based option pricing and hedging approach in markets with both fixed and proportional transaction costs: we extend the framework developed by Davis et al. (SIAM J. Control Optim., 31 (1993) 470) and formulate the option pricing and hedging problem. We propose and implement a numerical procedure for computing option prices and corresponding optimal hedging strategies. We present a careful analysis of the optimal hedging strategy and elaborate on important differences between the exact hedging strategy and the asymptotic hedging strategy of Whalley and Wilmott (RISK 7 (1994) 82). We provide a simulation analysis in order …
A Unified Approach to Portfolio Optimization with Linear Transaction Costs
2004
In this paper we study the continuous time optimal portfolio selection problem for an investor with a finite horizon who maximizes expected utility of terminal wealth and faces transaction costs in the capital market. It is well known that, depending on a particular structure of transaction costs, such a problem is formulated and solved within either stochastic singular control or stochastic impulse control framework. In this paper we propose a unified framework, which generalizes the contemporary approaches and is capable to deal with any problem where transaction costs are a linear/piecewise-linear function of the volume of trade. We also discuss some methods for solving numerically the p…
Do Investors Care About Noise Trader Risk?
2011
International audience; The link between investor sentiment and asset valuation is at the center of a long-running debate in behavioral finance. Using a new composite sentiment indicator, we show that the conventional risk does not explain the abnormal returns of portfolios most sensitive to the sentiment factor. Our result supports the existence of a sentiment risk valued by financial markets. We also find that the firms more impacted by the sentiment risk correspond to difficult-to-arbitrage and hard-to-value stocks, e.g. small stocks, growth stocks, young stocks, unprofitable stocks, lower dividend-paying stocks, intangible stocks and high volatility stocks.
Is Sentiment Risk Priced By Stock Market?
2012
International audience; This study tests if the financial markets price the investors sentiment risk. We construct portfolios based upon the stock returns exposure to sentiment. Our results show that the portfolio returns are positively correlated with the exposure of stocks to sentiment. The strategy that consists of buying stocks with the highest exposure to sentiment and selling stocks with the lowest exposure to sentiment generates a significant raw profit. Exploring the sources of profit, we find that neither the traditional risk factors nor the momentum factor can account for the profit. However, we find that the addition of the sentiment risk premium contributes to explain the profit.
STUDY REGARDING THE MARKOWITZ MODEL OF PORTFOLIO SELECTION
2015
The Markowitz model was introduced through the work of Harry Markowitz (1952) and analyzes the risk and the rentability of a diversified portfolio of securities. In our research, we want to use the Markowitz model in order to identify the structure of the optimal portfolio of risky assets, in other words the efficient portofolio. The study, conducted on three romanian companies from the construction sector, listed on the Bucharest Stock Exchange, leads to the conclusion that the portfolio is illegitimate, so it is necessary to sell the securities of the companies in the absence, procedure known as short sell.
Theoretical and Methodological Considerations on the Public Offers
2013
This paper describes the most important characteristics of the public offers, both from the theoretical and methodological view. The European Union emphasizes clarity and transparency. The author focuses on specific provisions of European Directive and Romanian law and regulations related to voluntary and mandatory takeover bids, on characteristics such as price, offeror and offeeree right, offer timetable.
