【摘要】:在金融經(jīng)濟(jì)相關(guān)研究之中,波動(dòng)率是非常重要的關(guān)鍵變量,對(duì)資產(chǎn)報(bào)酬波動(dòng)的預(yù)測(cè)是眾多的投資決定的關(guān)鍵前提信息。在投資組合交易策略、風(fēng)險(xiǎn)控制、金融衍生品資產(chǎn)定價(jià)以及制定貨幣政策之中,我們都需要波動(dòng)率這個(gè)關(guān)鍵信息。因此,對(duì)于市場(chǎng)波動(dòng)率的預(yù)測(cè),是金融市場(chǎng)的一個(gè)重大的研究任務(wù)。 本文選取基于無(wú)模型隱含波動(dòng)率計(jì)算而得的波幅指數(shù)VHSI為研究對(duì)象,實(shí)證研究發(fā)現(xiàn):在應(yīng)用包含回歸法時(shí),實(shí)證發(fā)現(xiàn)波幅指數(shù)VHSI包含信息量涵括了GARCH、 GJR-GARCH波動(dòng)率模型所含信息量;對(duì)于波幅指數(shù)VHSI預(yù)測(cè)是否包含SV模型所含信息,此方法不能夠得出肯定的結(jié)論;在應(yīng)用正交法時(shí),實(shí)證發(fā)現(xiàn)不管是否考慮時(shí)變波動(dòng)風(fēng)險(xiǎn)溢價(jià),波幅指數(shù)VHSI的預(yù)測(cè)對(duì)它本身的歷史波動(dòng)信息都是有效的,而且波幅指數(shù)VHSI的預(yù)測(cè)所含信息量能夠全部涵括歷史波動(dòng)率模型所含信息;不管風(fēng)險(xiǎn)溢價(jià)是恒定風(fēng)險(xiǎn)溢價(jià)還是時(shí)變風(fēng)險(xiǎn)溢價(jià),波幅指數(shù)VHSI都包含了歷史跳躍信息;與基于計(jì)量模型的歷史波動(dòng)率模型相比,波幅指數(shù)VHSI反映了一些有關(guān)未來(lái)跳躍行為的增量信息。因此可以說(shuō),波幅指數(shù)VHSI是對(duì)未來(lái)市場(chǎng)波動(dòng)率的一個(gè)有效預(yù)測(cè)。
[Abstract]:Volatility is a very important key variable in financial and economic research, and the prediction of asset return volatility is the key premise of many investment decisions. In portfolio trading strategies, risk control, asset pricing for financial derivatives and monetary policy, we all need the key message of volatility. Therefore, the prediction of market volatility is an important research task of financial market. In this paper, the amplitude index (VHSI), which is based on the calculation of model-free implied volatility, is selected as the research object. The empirical study finds that the amplitude index VHSI includes the information of GJR-GARCH and GJR-GARCH volatility model when the inclusion regression method is applied. As to whether the amplitude index VHSI prediction contains the information contained in SV model, this method can not draw a definite conclusion. In the application of orthogonal method, it is found that whether or not time-varying volatility risk premium is considered or not, The prediction of amplitude index VHSI is effective for its own historical fluctuation information, and the amount of information contained in the prediction of amplitude index VHSI can include all the information contained in the historical volatility model. Regardless of whether the risk premium is a constant risk premium or a time-varying risk premium, the amplitude index VHSI contains historical jump information, compared with the historical volatility model based on the econometric model. The amplitude index VHSI reflects some incremental information about future jump behavior. Therefore, the amplitude index VHSI is an effective prediction of the market volatility in the future.
