1、中文摘要摘要:本文把統(tǒng)計(jì)物理學(xué)中的滲流理論與金融數(shù)學(xué)中的股票市場(chǎng)結(jié)合起來研究股票價(jià)格的波動(dòng)過程和收斂的極限狀態(tài).根據(jù)泊松分布和滲流理論構(gòu)造了股票價(jià)格的隨機(jī)模型,并利用特征函數(shù)的性質(zhì)論證了該模型的收斂性,得出所構(gòu)造的股票價(jià)格隨機(jī)模型的特征函數(shù)收斂到某一個(gè)Black.Scholes公式的特征函數(shù)的結(jié)論.加入實(shí)際中因突發(fā)事件引起的跳躍因素來修正模型,使得模型更加接近股票價(jià)格的波動(dòng)過程.本文進(jìn)一步計(jì)算出股票價(jià)格模型的期望與方差,討論了跳躍服從對(duì)數(shù)泊松分布時(shí)模型的無套利價(jià)格的下界.由于我國(guó)的證券市場(chǎng)是一個(gè)典型的復(fù)雜系統(tǒng),受一些因素的影響,因此需
2、要找到更能反應(yīng)真實(shí)市場(chǎng)特征的金融模型,這就必須對(duì)證券市場(chǎng)的一些統(tǒng)計(jì)特征量進(jìn)行分析.本文根據(jù)Ising模型構(gòu)造證券成交量模型,用上海、深圳證券交易所十只證券的成交量數(shù)據(jù)來擬合模型相應(yīng)的累積分布、自相關(guān)函數(shù)等統(tǒng)計(jì)特征圖.計(jì)算結(jié)果表明證券成交量的累積分布具有寬尾的特征,對(duì)應(yīng)的統(tǒng)計(jì)特征圖可以正確反應(yīng)真實(shí)證券市場(chǎng)的規(guī)律.關(guān)鍵詞:泊松分布;滲流理論;Black—Scholes公式;特征函數(shù);無套利價(jià)格;證券交易量;Ising模型;自相關(guān)函數(shù);分類號(hào):F830.91ABSTRACTABSTRACT:Inthispaper,wearecombinin
