發(fā)布時(shí)間:2019-04-29 20:33
【摘要】:在去除交易量時(shí)間趨勢(shì)與自回歸的基礎(chǔ)上,大量的實(shí)證檢驗(yàn)發(fā)現(xiàn)即期交易量與價(jià)格波動(dòng)之間存在正相關(guān)關(guān)系.然而交易量序列同時(shí)還存在異方差現(xiàn)象.用同時(shí)去除時(shí)間趨勢(shì)、自相關(guān)與異方差的交易量作為信息流的代表,來(lái)研究?jī)r(jià)格波動(dòng)與交易之間的關(guān)系,結(jié)果發(fā)現(xiàn),新的交易量序列能更好地解釋收益率的異方差特征,而且市場(chǎng)成熟度不同的國(guó)家,交易量序列的這種解釋能力也不同.
[Abstract]:On the basis of removing the time trend of trading volume and auto-regression, a large number of empirical tests show that there is a positive correlation between spot trading volume and price fluctuation. However, Heteroscedasticity also exists in the trading volume series. The relationship between price fluctuation and transaction is studied by removing the time trend and auto-correlation and heteroscedasticity as the representative of information flow. The results show that the new trading volume series can better explain the heteroscedasticity characteristics of the rate of return. And the market maturity of different countries, trading volume sequence of this interpretation capacity is also different.
