关于QFII投资羊群效应的实证分析
Empirical Analysis of Herd Behavior forQFII
 [PDF]

张洋,
Finance (FIN) , 2015, DOI: 10.12677/FIN.2015.54009
Abstract:
以2004年第一季度到2014年第三季度A股市场上的前十大流通股名单中QFII的持股明细数据为样本,采用LSV模型和PCM模型并引进时间维度,通过测量羊群行为度来判断QFII在我国证券市场上是否存在羊群效应。同时,动态地比较不同时期QFII的羊群行为度,分析我国在股市暴涨暴跌时期QFII羊群行为的特征。结果发现,QFII在我国证券市场的投资过程中具有明显的羊群效应,其交易行为不遵循价值投资的理念。在股市暴涨暴跌的时候,其羊群效应会更加显著。在股市暴涨的时候,QFII体现的是买方羊群行为,在股市暴跌的时候,QFII体现的是卖方羊群行为。
Using the holding position details of QFII in the top ten tradable A-share market listed companies as samples from the first quarter of 2004 to the third quarter of 2014, the degrees of herd behavior of QFII are measured by using LSV model and PCM model combined with time dimension to determine whether there exit herd effects in Chinese securities market. In the meantime, to compare QFII herd behavior of different periods dynamically, the QFII herd behavior characteristics are analyzed during the period of the stock market prices soaring and falling. The result shows that QFII has significant herd behaviors in investment process in Chinese securities market, and its trading behavior does not follow the concept of value investing. When the stock market prices soar and fall, the herd behaviors will be more significant. With the stock market booming, QFII reflects a buyer herd behavior; while with the stock market crashing, QFII reflects a seller herd behavior.

Abstract:
本文结合某蛋白粉厂干燥塔实例,设计了干燥塔尾气余热利用方案,通过设置换热器进行余热回收,将常温20空气进行预热,提高空气温度约80,预热后的空气再经过过滤器,由鼓风机送入加热器加热后进入干燥塔,减少蒸汽的使用量,以达到减少煤炭消耗、节能减排的目的。经分析计算得到该方案核心装置换热器的设计结果,并对方案的初投资和运行效果、投资回收期等经济性指标进行了计算,表明该方案在尾气回收中可以取得较为实用的经济效益和社会效益
In combination with a protein powder factory drying tower example, an exhaust waste heat scheme is de- signed. By setting up the waste heat exchanger, the air is preheated from 20?C to 80?C. The preheated air goes through the filter into heater, heated into the drying tower, which can reduce the steam consumption and the coal consumption, achieving the goal of energy conservation and emissions reduction. Through analysis and calculation, the heat ex- changer design results are obtained. The initial investment, the operation results, and the investment capital are calcu- lated, which shows that the scheme in drying tower tail gas recovery has the economic and social benefits.
QFII交易策略对股票收益影响的实证分析
Empirical Analysis of Impacts of QFII Trading Strategies on Stock Returns
 [PDF]

Finance (FIN) , 2015, DOI: 10.12677/FIN.2015.54010
Abstract:
从行为金融学的角度出发,考察2010年三季度至2014年三季度70家QFII的交易策略对股票收益的影响。首先,通过MT指标的构建,检验惯性或反转现象的存在性;然后,按照MT值将不同的股票进行分类,采用Jegadeesh和Titman (1993)的模型研究惯性或反转交易策略的收益性,考察QFII的惯性或反转交易策略对股票收益的影响。结果表明,QFII大多倾向于追涨杀跌的惯性交易策略,并且惯性收益随着MT值的增长而增长,说明QFII的惯性交易策略影响了股票的惯性收益。
From the viewpoint of behavioral finance, this paper investigates the impact on stock returns of trading strategies for 70 QFII from the third quarter of 2010 to the third quarter of 2014. Firstly, the existence of momentum or contrarian phenomenon is tested by constructing a MT measure; then, the sample stocks are classified by the value of MT, and the stock returns are examined by using the model of Jegadeesh and Titman (1993) to analyze the impact of momentum or contra-rian strategy of QFII on stock return. Empirical results show that QFII tend to mostly use momentum strategy and also momentum return grows with the growth of MT value, implying that momentum strategy of QFII affects stocks’ momentum return.
基于VaR的新三板企业股权质押率分析—以枫盛阳(430431)为例
Analysis of Loan-to-Value Raito for NEEQ Companies Based on VaR—A Case Study of Fengshengyang (430431)
 [PDF]

Abstract:
股权质押贷款是新三板企业主要的债务融资方式,质押率的大小直接反映了股权质押贷款中的风险暴露程度。以新三板挂牌企业枫盛阳(430431)为例,采用VaR方法计算其质押率并通过模拟贷款分析击穿频率,判断质押率上限(30%)设定的合理性;在此基础上,以三板做市(899002)代表整个市场,对比枫盛阳(430431)与三板做市(899002)的击穿频率,分析个体企业和市场总体的差异。研究发现,模拟贷款期限越短VaR值越小,使得质押率越高,击穿频率越高;反之亦然。确定股权质押率时不仅要考虑市场的情况,还需要对所属行业企业资质进行针对性分析考虑。
Stock loan is a main financial access of debt type for SMEs in the NEEQ market, and the loan-to- value ratio reflects the risk exposure of stock loan. Using Fengshengyang (430431) as the case of NEEQ companies for analysis, this paper calculates loan-to-value ratio based on VaR, and gets the breakdown frequency by simulating loans, which in turn tests the rationality of the maximum ratio of 30% of stock loan. Considering NEEQ component index (899002) as the representative of the whole NEEQ market, the breakdown frequency of Fengshengyang (430431) and NEEQ component index (899002) are compared to find the difference between a specific company and the whole market. The results show that the shorter the term of simulating loans, the smaller the VaR value is, which makes both the loan-to-value ratio and the breakdown frequency higher; and versa oth-erwise. To determine the loan-to-value ratio, not only the market situation, but also specific factors of industry and enterprise are needed to be considered.

Abstract:
以聚乙烯吡咯烷酮为分散剂,水及无水乙醇为反应介质,偶氮二异丁腈引发剂,采用分散聚合的方法,制备出了一系列亚微米级的PS微球,分析了单体、引发剂、分散剂的用量,反应介质组成和搅拌速度对产物粒径及粒径分布的影响。结果表明,利用分散聚合,初步实现了PS粒径的可控,反应物组成对微球粒径及分布起主要作用,而搅拌速率只对微球粒径有影响,对粒径分布影响不大。
Polystyrene microspheres sized in sub micron were prepared by a dispersion polymerization with PVP as dispersant, H2O and ethanol as reaction medium, AIBN as initiator. The effects of H2O-ethanol ratio, string speed and amount of styrene, AIBN and PVP on particle size and distribution were discussed. Results show that PS spheres size could be preliminarily control. The component of reactant is the main effect of size and distribution, meanwhile, spin rate only effects sphere size.
