Hedging Effectiveness

Hedging Effectiveness

The extent to which hedging an investment actually reduces risk. There are a large number of hedging strategies one can use. For example, one may take a long position on a security and then sell short the same security. However, some strategies may be forms of naive diversification, which reduce hedging effectiveness. In an extreme example, if one buys a stock and then short sells a bond in a completely different industry, one is more likely to increase risk rather than decrease it.

The hedging effectiveness of the SDE-MV model outperforms the MV model and the FSDE model; thus the SDE-MV model performs better both in sample and out of sample when the Hurst parameter of the spot is larger than the futures.
Our results show that purchasing gap insurance can generally increase the hedging effectiveness in multiple ways by reducing basis risk, thus increasing shareholder value and, at the same time, lowering shortfall risk.
For explanation of hedging effectiveness, basis risk and derivation of hedge ratio, see, among others, Hull (2012).
Overall, the results are comparable to the baseline results, suggesting that the conclusion made earlier with respect to the larger estimation period still hold in general and in particular the institutional involvement is related to the hedging effectiveness of real estate stocks.
Based on the out of sample hedging effectiveness given by the variance reduction, the methods are compared.
In addition, for any given model the more "exotic" the option, the poorer the hedging effectiveness.
The underlying index, which is derived from the price of a basket of routes, could not hedge well for individual route because hedging effectiveness is directly related to the underlying risk.
There are three primary methods of testing the hedging effectiveness of forwards, futures, and swaps when the critical terms of the hedging derivative and the hedged item are not identical: the dollar-offset method, the variability-reduction method, and the regression method.

They have helped us build portfolio stress-tests that enable us to measure the impact of worst-case market scenarios on our hedging effectiveness as well as risk decomposition tools to support our risk budgeting process.
Sensitivity analysis concludes the research by exploring the impact of basis risk, variable hedging cost, jump volatility, and jump intensity on hedging effectiveness.
