题目:沪深300股指期货对股票市场的波动性影响研究摘要沪深300股指期货是以沪深300指数为合约目标物的金融期货合约,并且在交割日期以沪深300指数的现货价格作为基准结算价格。作为一种具有高杠杆性的金融衍生工具,文章通过对比沪深300股指期货推出前后对股票市场波动性的影响来研究其运行机制,并为投资者选择提供相关的建议。本文选用2008年12月1日到2018年12月6日沪深300指数日收盘价作为研究对象共2438个样本数据。2010年4月16日沪深300股指期货推出。通过ADF检验,ARCH效应检验,GARCH族模型分析股指波动性对股票市场影响,实证结果得出以下主要结论:沪深300指数的时间序列将会表现出聚集的现象,在前面时段间波动一直偏大,然而在之后的时期,就会一直处于偏小的状态,证实了沪深300股指期货推出后存在一定杠杆性,放大了新信息对股市的冲击,但总体上降低了股市波动性。关键词:股指期货、沪深300指数、股指波动性、GARCH族模型I沪深300股指期货对股票市场的波动性影响研究摘要AbstractCSI300stockindexfuturesarefinancialfuturescontractswiththeCSI300indexasthesubjectmatterofthecontract,andthespotpriceoftheCSI300indexasthebenchmarksettlementpriceonthedeliverydate.Asahighlyleveragedfinancialderivativetool,thispaperstudiesitsoperatingmechanismbycomparingtheimpactofCSI300stockindexfuturesonstockmarketvolatilitybeforeandaftertheirlaunch,andprovidesrelevantsuggestionsforinvestorstochoose.ThispaperchoosestheclosingpriceofCSI300indexfromDecember1,2008toDecember6,2018astheresearchobject,andhas2438sampledata.OnApril16,2010,CSI300stockindexfutureswerelaunched.ThroughtheanalysisofGARCHfamilymodels,ThroughADFtest,ARCHeffecttest,GARCHfamilymodelisusedtoanalyzetheimpactofstockindexvolatilityonstockmarket.Theempiricalresultsshowthefollowingmainconclusions:ThetimeseriesoftheCSI300Indexwillcontinuetofluctuateinacertainperiodoftime,whilethefluctuateinthefollowingperiodwillcontinuetobesmallandclustereffectappears,whichconfirmsthatthereiscertainleverageafterthelaunchoftheCSI300IndexFutures,andenlargestheimpactofnewinformationonthestockmarket,butgenerallyreducesthevolatilityofthestockspotmarket.Keywords:stockindexfutures,CSI300index,stockindexvolatili...
