This book was released on 2010 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines hedging effectiveness of futures contract on a financial asset and commodities in Indian markets. In an emerging market context like India, the growth of capital and commodity futures market would depend on effectiveness of derivatives in managing risk. For managing risk, understanding optimal hedge ratio is critical for devising effective hedging strategy. We estimate dynamic and constant hedge ratio for Samp;P CNX Nifty index futures, Gold futures and Soybean futures. Various models (OLS, VAR, and VECM) are used to estimate constant hedge ratio. To estimate dynamic hedge ratios, we use VAR-MGARCH. We compare in-sample and out-of-sample performance of these models in reducing portfolio risk. It is found that in most of the cases, VAR-MGARCH model estimates of time varying hedge ratio provide highest variance reduction as compared to hedges based on constant hedge ratio. Our results are consistent with findings of Myers (1991), Baillie and Myers (1991), Park and Switzer (1995a,b), Lypny and Powella (1998), Kavussanos and Nomikos (2000), Yang (2001), and Floros and Vougas (2006).

Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the hedging effectiveness of Universal Stock Futures trading in London at protecting the underlying spot position from variations in portfolio returns using four different hedge ratios. The hedge ratios under analysis are: the naive 1:1 hedge ratio, the risk-minimizing hedge ratio, a modified version of the risk-minimizing hedge ratio and a time-varying hedge ratio under a GARCH (1,1) process which is allowed to change on a daily basis. The aim of the research is to examine which hedge ratio provides the best protection from market fluctuations when hedging a stock spot position with its futures contract. The findings suggest that the time-varying hedge ratio provides a better hedging strategy than the other techniques although some companies exhibited a smaller portfolio variance when protected with a constant hedge ratio.

Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the hedging effectiveness of the Standard amp; Poor's (Samp;P) 500 stock index futures contract using weekly settlement prices for the period July 3rd, 1992 to June 30th, 2002. Particularly, it focuses on three areas of interest: the determination of the appropriate model for estimating a hedge ratio that minimizes the variance of returns; the hedging effectiveness and the stability of optimal hedge ratios through time; an in-sample forecasting analysis in order to examine the hedging performance of different econometric methods. The hedging performance of this contract is examined considering alternative methods, both constant and time-varying, for computing more effective hedge ratios. The results suggest the optimal hedge ratio that incorporates nonstationarity, long run equilibrium relationship and short run dynamics is reliable and useful for hedgers. Comparisons of the hedging effectiveness and in-sample hedging performance of each model imply that the error correction model (ECM) is superior to the other models employed in terms of risk reduction. Finally, the results for testing the stability of the optimal hedge ratio obtained from the ECM suggest that it remains stable over time.

This book was released on 2016 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study demonstrates how hedging methodologies can be evaluated in a modern risk management context and provides a hedging effectiveness of dynamic hedge ratios. The results provide an indication of the superior performance of the time varying hedge ratio as compared with traditional constant ratio. Time varying hedge ratio estimated by CCC-GARCH model shows a clear advantage over linear regression based constant hedge ratio in minimizing the variance (risk) of portfolio returns over the whole 10 years of analysis. The time-varying hedge ratio estimated in our study provides an efficient measure for bond investors to maximize the value of their investments by changing positions in both spot and future markets of U.S. Treasuries with the change in actual yields of cash market. The results are robust in the sense that constant conditional correlation model does take account of the conditional heteroskedasticity present in the data in case of spot market.

Book excerpt: We use the classic agency model to derive a time-varying optimal hedge ratio for low-frequency time-series data: the type of data used by crop farmers when deciding about production and about their hedging strategy. Rooted in the classic agency framework, the proposed hedge ratio reflects the context of both the crop farmer's decision and the crop farmer's contractual relationships in the marketing channel. An empirical illustration for the Dutch ware potato sector and its futures market in Amsterdam over the period 1971 - 2003 reveals that the time-varying optimal hedge ratio decreased from 0.34 in 1971 to 0.24 in 2003. The hedging effectiveness, according to this ratio, is 39%. These estimates conform better with farmers' interest in using futures contracts for hedging purposes than the much higher estimates obtained when price risk minimisation is the only objective considered.

This book was released on 2001 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the hedging effectiveness of Australian, Hong Kong and Japanese stock futures markets. For each market two sets of futures indices are used in the empirical tests. Effectiveness of four different hedging ratios depending on different estimation procedures are investigated. The unhedged, the traditional hedge and the minimum variance hedge ratios are all constant while the bivariate GARCH hedge ratio is time-varying. The effectiveness of the hedge ratio are compared by investigating the out-of-sample performance of the four ratios. The whole sample consist of daily returns from January 1990 to December 1998. Two out-of-sample periods are used January1997 to December 1998 (two years) and from January 1998 to December 1998 (one year). Results show that the time-varying GARCH hedge ratio out-performs the constant ratios in most of the cases but not all. This is true using both out-of-sample periodsKeyWords: Hedge Ratio, Bivariate GARCH, Cash Index, Futures Index, Variance.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper estimates time-varying and constant hedge ratios, and investigates their performance in reducing freight rate risk in routes 1 and 1A of the Baltic Freight Index. Time-varying hedge ratios are generated by a bivariate error correction model with a GARCH error structure. We also introduce an augmented GARCH (GARCH-X) model where the error correction term enters in the specification of the conditional covariance matrix. This specification links the concept of disequilibrium (as proxied by the magnitude of the error correction term) with that of uncertainty (as reflected in the time varying second moments of spot and futures prices). In- and out-of-sample tests reveal that the GARCH-X specification provides greater risk reduction than a simple GARCH and a constant hedge ratio. However, it fails to eliminate the riskiness of the spot position to the extent evidenced in other markets in the literature. This is thought to be the result of the heterogeneous composition of the underlying index. It seems that restructuring the composition of the Baltic Freight Index (BFI) so as to reflect homogeneous shipping routes may increase the hedging e�tiveness of the futures contract. This by itself indicates that the imminent introduction of the Baltic Panamax Index (BPI) as the underlying asset of the Baltic International Financial Futures Exchange (BIFFEX) contract is likely to have a beneficial impact on the market.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the hedging effectiveness of the S&P CNX Nifty index futures by employing four competing models, viz., the simple Ordinary Least Squares (OLS) method, the Bivariate Vector Autoregressive (BVAR) model, the Vector Error Correction Model (VECM), and the multivariate Generalized Autoregressive Conditional Heteroscedasticity (GARCH) with error correction model. The hedge performances obtained from the different econometric models for the in-sample and out-of-sample periods are compared in terms of variance minimization criterion.

Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the hedging effectiveness of the FTSE/ATHEX-20 and FTSE/ATHEX Mid-40 stock index futures contracts in the relatively new and fairly unresearched futures market of Greece. Both in-sample and out-of-sample hedging performances using weekly and daily data are examined, considering both constant and time-varying hedge ratios. Results indicate that time-varying hedging strategies provide incremental risk-reduction benefits in-sample, but under-perform simple constant hedging strategies out-of-sample. Moreover, futures contracts serve effectively their risk management role and compare favourably with results in other international stock index futures markets. Estimation of investor utility functions and corresponding optimal utility maximising hedge ratios yields similar results, in terms of model selection. For the FTSE/ATHEX Mid-40 contracts we identify the existence of speculative components, which lead to utility-maximising hedge ratios, that are different to the minimum variance hedge ratio solutions.

Available in PDF, EPUB and Kindle. Book excerpt: This paper analyzes the influence of sudden changes in the unconditional volatility on the estimation and forecast of volatility and its impact on futures hedging strategies. We employ several multivariate GARCH models to estimate the optimal hedge ratios for the Spanish stock market including in each one some well-known patterns that may affect volatility forecasts (asymmetry and sudden changes). The main empirical results show that more complex models including sudden changes in volatility outperform the simpler models in hedging effectiveness both with in-sample and out-of-sample analysis. However, the evidence is stronger when the tail loss distribution is used as a measure for the effectiveness Value at Risk (VaR) and Expected Shortfall (ES) suggesting that traditional measures based on the variance of the hedge portfolio should be used with caution.

Download or read book The Effect of Asymmetries on Optimal Hedge Ratios written by Chris Brooks and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There is widespread evidence that the volatility of stock returns displays an asymmetric response to good and bad news. This article considers the impact of asymmetry on time-varying hedges for financial futures. An asymmetric model that allows forecasts of cash and futures return volatility to respond differently to positive and negative return innovations gives super in-sample hedging performance. However, the simpler symmetric model is not inferior in a hold-out sample. A method for evaluating the models in a modern risk-management framework is presented, highlighting the importance of allowing the optimal hedge ratios to be both time-varying and asymmetric.
