滬深300指數(shù)期貨最優(yōu)套期保值比率的計(jì)算
[Abstract]:As a type of futures trading, stock index futures trading and general commodity futures trading have the same characteristics and processes. Stock index futures is a leveraged investment tool. As long as it is judged in the right direction, it is likely to yield a very high return. Investors mainly use it to manage the risk of the stock portfolio. That is to guard against systemic risk (what we commonly call market risk) or arbitrage to gain risk-free returns. Hedging is the origin of futures, and hedging strategy is also one of the most fundamental strategies of stock index futures. By using stock index futures to hedge with a certain portfolio of stocks, we can avoid the price risk in the spot market. If futures positions match well with spot, hedging can eliminate most of the systemic risk in the spot market. The key to hedge stock index futures is to determine the hedge ratio. There are two kinds of research on modern optimal hedging ratio, one is risk minimization hedge ratio, the other is utility maximization hedging ratio. The model used to estimate hedging ratio is mainly (OLS), vector autoregressive model (VAR), based on cointegration error correction model (ECM), vector error correction model (VECM), Generalized autoregressive conditional heteroscedasticity model (GARCH),) and error modified GARCH model (ECM-GARCH) are represented. On April 16, 2010, after more than three years of simulated trading, China's stock index futures finally ushered in a formal listing transaction. Based on the actual trading data of Shanghai and Shenzhen 300 index spot and futures, this paper estimates the risk minimization hedging ratio and utility maximization hedging ratio by using ECM-GARCH model and mean-variance model using Eviews5.0 statistical software. It is found that the risk minimization hedging ratio is higher than the utility maximization hedging ratio both within and outside the sample.
