The chapter investigates chosen hedging strategies with options as useful risk hedging instruments. Assuming that average investor prefers greater return, is risk-averse, and prefers greater positive skewness, the performance of different hedged and unhedged portfolios is evaluated using stochastic dominance (SD) criteria and data envelopment analysis (DEA). The SD is examined up to the third degree (TSD) using Davidson-Duclos (DD) test. In the DEA, a super efficiency BCC model is used. It is investigated how these two methodologies can be combined and how the TSD criteria can be integrated into DEA in order to simplify the analysis of determining efficient hedging strategies with options.

This article explores the possibility of implementing weather derivatives in cultural events through an empirical application to celebrations of Comunidad Valenciana (Spain). Temperature- and rainfall-based options geared to the three counties of this Autonomous Community are proposed to mitigate the risk exposure of this event. First, the contracts are priced through the Index Value Simulation and Daily Simulation techniques, which rely on Monte Carlo simulations. Next, they are used to design realistic hedging strategies, which are evaluated under different meteorological scenarios. The degree of geographical basis risk affecting this region, as measured by the root mean square error, is also assessed since it is a common issue refraining the application of weather derivatives. The outcomes attained emphasize the high hedging potential of the suggested tools and indicate the appropriateness of considering, on a case-by-case basis, the possibility of using a combination of derivatives geared to nearby stations as a solution to mitigate basis risk exposure.

Purpose – The purpose of this study is to delineate the factors influencing the use of financial derivatives by non-financial firms in managing their exchange rate exposure. In total, 219 non-financial firms are surveyed in regard to their financial hedging decision. Design/methodology/approach – This study is conducted via a survey and the questionnaires were sent to the treasurers and financial controller of the firms. Descriptive analysis is employed to assess the profiles of the respondents. Then, factor analysis is carried out to determine the factors influencing the use of financial derivatives in Malaysia. Findings – The results indicate that the hedging decision of non-financial firms is influenced by their assertive level toward the market and regulators and also how flexible they are for derivative instruments. The intellectual capability that firms acquire to perform hedging strategies is also vital in influencing them to make hedging decision. Practical implications – The insights of this survey would assist and prepare firms to hedge their exchange rate risk by employing financial derivatives. Knowing the influences of firms' adoption of currency derivatives would allow policy makers to formulate their policies in boosting the liquidity of Malaysian derivative market. Originality/value – This study presents findings on the factors influencing the execution of financial hedging by non-financial firms in Malaysia. Survey data are used to seek for the feedback from the market players in order to provide empirical evidence on the corporate use of financial hedging.

The conditional risk-minimizing hedge strategies are estimated for an international portfolio of the US, UK and Switzerland stocks, for the period of February of 1973 to March of 2002. The empirical results show that the optimal dynamic hedging strategies can capture partially the currency fluctuations, and greatly reduce the currency risk and enhance the risk-adjusted returns of the portfolio with significant foreign currency exposures. </span></p>

The adoption of floating foreign exchange rate regime in the 1990s and international trade have led to increased exposure of Kenyan firms to foreign exchange risk. Foreign exchange risk can affect a firm’s expected cash flows, and by extension, its financial performance. This paper examines the effects of foreign exchange risk hedging techniques on the financial performance of publicly listed firms in Kenya. The target population constituted all the 54 firms that were continuously listed on the Nairobi Securities Exchange during the study period, from 2011 to 2016. The study used panel data research design. Secondary data was obtained from financial statements of the listed firms. The data was coded and analysed using descriptive and inferential statistics—correlation and regression—with the aid of STATA software. The feasible generalised least square model was used to test the hypotheses. The results show currency hedging has a positive effect on financial performance. This implies that when hedging strategies and hedging tools are implemented appropriately, they help firms achieve their financial objectives, increasing financial performance, hence creating value for shareholders.
