【摘要】:隔夜信息是資本市場(chǎng)信息的重要組成成分,對(duì)股票價(jià)格變動(dòng)有不可忽視的影響。按休市時(shí)間長(zhǎng)短將隔夜信息分為三部分并以逐步推進(jìn)的方式將日內(nèi)交易分為八個(gè)時(shí)段,研究隨后開(kāi)市一天內(nèi)隔夜信息對(duì)股票收益率和波動(dòng)性的影響。研究結(jié)果表明:隔夜信息對(duì)資本市場(chǎng)收益率和波動(dòng)性均有顯著影響并且休市時(shí)間長(zhǎng)度不同的隔夜信息對(duì)收益率和波動(dòng)性的影響不同;驗(yàn)證了隔夜信息對(duì)波動(dòng)性杠桿效應(yīng)的存在,此外,結(jié)果顯示隔夜信息在開(kāi)盤(pán)一小時(shí)后可以融入到市場(chǎng)價(jià)格中。
[Abstract]:Overnight information is an important component of capital market information, which has an important influence on stock price change. The overnight information is divided into three parts according to the length of the closing time, and the intraday trading is divided into eight periods in a progressive way. The influence of overnight information on the stock yield and volatility is studied after the opening of the market. The results show that: overnight information has a significant impact on the return and volatility of the capital market, and the overnight information with different closure time has different effects on the return and volatility; In addition, the results show that the overnight information can be integrated into the market price one hour after opening.
