基于投资者情绪视角下的股指期货套期保值

Hedging of Stock Index Futures from the Perspective of Investor Sentiments

以沪深300股指期货为研究对象,采用t-Copula-ECM-GARCH动态模型,研究沪深300股指期货的最优套期保值策略,并将其与最小二乘法(OLS)等传统套期保值策略进行比较。通过主成分分析方法(PCA)构建股票现货市场和股指期货市场的投资者情绪指数,并将其分别引入上述模型中。结果表明,与未考虑投资者情绪的套期保值策略相比,加入投资者情绪指数后沪深300股指期货的套期保值效果明显提高。说明基于投资者情绪的套期保值模型比原有模型规避风险的效果更好。
