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(shí)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(diǎn)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(fèi)貸款業(yè)務(wù)過程中的內(nèi)部風(fēng)險進(jìn)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(jìn)行橫截面檢驗(yàn)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。
In this article we firstly puts forward and discusses the quantitative analysis of real estate investment systematic risk and earnings with the investment economics theory and the probability and mathematical statistics method , secondly puts and discusses the quantitative analysis of real estate investment nonsystematic risk and earnings with monte carlo method and the probability and mathematical statistics method , finally discusses the quantitative analysis of real estate investment total risk and earnings with the probability and mathematical statistics method 文中首先提出并論述了利用投資經(jīng)濟(jì)學(xué)理論和概率數(shù)理統(tǒng)計方法對房地產(chǎn)投資系統(tǒng)風(fēng)險及其收益進(jìn)行定量分析;其次提出并闡述了利用蒙特卡洛方法和概率數(shù)理統(tǒng)計方法對房地產(chǎn)投資非系統(tǒng)風(fēng)險及其收益進(jìn)行定量分析;最后論述了利用概率數(shù)理統(tǒng)計方法對房地產(chǎn)投資綜合風(fēng)險及其收益數(shù)值的定量分析方法。
There are also some abnormity in nowadays security market in chinaserious systematic risk embodied by abnormal fluctuating of stock price ; market maker " manipulating prevail on the background of imperfect information reveal system and regulation system ; market credit and interests and confidence of public investors impaired by the outstanding nonsystematic risk of individual stock 分析我國證券市場發(fā)展現(xiàn)狀,股市價格的異常波動幅度體現(xiàn)了嚴(yán)重的系統(tǒng)風(fēng)險,在信息披露制度很不完善、監(jiān)管體武漢理工大學(xué)碩士學(xué)位論文制不夠健全的背景下,流行“莊家”炒作行情,個股的非系統(tǒng)性風(fēng)險非常突出,傷害了市場信用和公眾投資者的利益和信心。
