Portfolio investment is an efficient way to reduce risk . risk can be classified into systematic risk and nonsystematic risk , and the latter can be diversified by portfolio investment 投資組合是降低風(fēng)險的有效途徑,風(fēng)險可以分為系統(tǒng)風(fēng)險和非系統(tǒng)風(fēng)險,后者可以通過投資組合的方式加以分散和消除。
As a result , researcher found that the of sample stock was volatile and the linear relation of the model was not distinct . lastly , the study shows nonsystematic risk will make expected return change 從這一章的研究結(jié)果來看,樣本股票的值在研究期間很不穩(wěn)定,所擬合模型的線性關(guān)系也不顯著,本章實證結(jié)果表明上證a股市場股票定價行為不是均值-方差有效的。
( 2 , 1 , 7 ) nonsystematic convolutional codes are optimal convolutional codes on the same code length and information bit length condition , so they are adopted as space standard codes by ccsds ( consultative committee for space data systems ) ( 2 , 1 , 7 )非系統(tǒng)卷積碼在相同的碼長和信息長度下為最佳卷積碼,因此被ccsds (空間數(shù)據(jù)系統(tǒng)咨詢委員會)采納為空間標(biāo)準(zhǔn)碼。
The starting point of the thesis is oriented to nonsystematic risk management , i . e . , analyze the inherent risks of commercial banks with the car - purchasing loans , control and manage them by system - design and technology - design 本文研究的出發(fā)點被定位在非系統(tǒng)性風(fēng)險管理上,即對商業(yè)銀行在開展汽車消費貸款業(yè)務(wù)過程中的內(nèi)部風(fēng)險進行分析,并通過制度和技術(shù)設(shè)計來控制與管理風(fēng)險。
Furthermore , multi - investments can resolve the most part of nonsystematic risk . in chapter 4 , the thesis estimated the value of by means of time series regression firstly . secondly , we used ways of equilibrium analysis to test the risk - return relation of shanghai a - share 在第4章,本文先通過時間序列回歸估計了樣本股票的值,然后以上證綜合指數(shù)作為市場組合分期進行橫截面檢驗來考察上證a股的風(fēng)險-收益關(guān)系,本章采用了均衡分析方法。
