可变利率投资组合股票成交额

『壹』 请问：投资组合的收益率与股票的数量有什么关系可分散风险可否得到相应的风险溢价

投资组合的收益率:指一个投资组合的加权平均收益率。如购买10支股票，组合的收益率=总的收益/总的投资
你购买的不同股票数量不同，价格大数量多的股票权重就大。
比如购买2只股票，A股票10000股，价格8元，B股票数量5000股，价格4元。那么A股票的权重就是8*10000/（8*10000+4*5000）=80%，A股票的涨跌对总收益率的影响就是80%了。
分散风险不能得到相应的风险溢价。
风险和收益总是相伴而生的。高风险高收益，低风险低收益。
分散风险只是说尽量避免高风险高收益，寻求风险和收益的均衡
希望可以帮助你更好的理解

---------------------------------------------------------------------------------------------------------------------
一般理论上来说,利率下降时,股票的价格就上涨；利率上升时,股票的价格就会下跌。因此,利率的高低以及利率同股票市场的关系,也成为股票投资者据以买进和卖出股票的重要依据。

利率对于股票的影响可以分成三种途径:

一是利率变动造成的资产组合替代效应,利率变动通过影响存款收益率,投资者就会对股票和储蓄以及债券之间做出选择,实现资本的保值增值。

通过资产重新组合进而影响资金流向和流量,最终必然会影响到股票市场的资金供求和股票价格。利率上升,一部分资金可能从股市转而投向银行储蓄和债券,从而会减少市场上的资金供应量,减少股票需求,股票价格下降；反之,利率下降,股票市场资金供应增加,股票价格将上升。

二是利率对上市公司经营的影响,进而影响公司未来的估值水平。

贷款利率提高会加重企业利息负担,从而减少企业的盈利,进而减少企业的股票分红派息,受利率的提高和股票分红派息降低的双重影响,股票价格必然会下降。相反,贷款利率下调将减轻企业利息负担,降低企业生产经营成本,提高企业盈利能力,使企业可以增加股票的分红派息。受利率的降低和股票分红派息增加的双重影响,股票价格将大幅上升。

三是利率变动对股票内在价值的影响。

股票资产的内在价值是由资产在未来时期中所接受的现金流决定的,股票的内在价值与一定风险下的贴现率呈反比关系,如果将银行间拆借、银行间债券与证券交易所的债券回购利率作为参考的贴现率,则贴现率的上扬必然导致股票内在价值的降低,从而也会使股票价格相应下降。股指的变化与市场的贴现率呈现反向变化,贴现率上升,股票的内在价值下降,股指将下降；反之,贴现率下降,股价指数上升。

以上的传导途径应该是较长的一个时期才能体现出来的,利率调整与股价变动之间通常有一个时滞效应,因为利率下调首先引起储蓄分流,增加股市的资金供给,更多的资金追逐同样多的股票,才能引起股价上涨,利率下调到股价上涨之间有一个过程。如我国央行自1996年5月以来的八次下调存款利率,到2002年1年期定期储蓄存款的实际收益率只有1.58%。在股票价格在较长时间内持续上涨的情况下,股票投资的收益率远远高于存款的报酬率,一部分储蓄存款转化为股票投资,从而加快了储蓄分流的步伐。从我国居民储蓄存款增长率来看,1994年居民储蓄存款增长率45.6%,之后增幅连年下滑,而同一时期股票市场发展迅速,1999年下半年开始储蓄分流明显加快,到2000年分流达到顶点,同年我国居民储蓄存款增长率仅为7.9%。这一年股票市场也牛气冲天。2001年储蓄分流则明显减缓,增长率14.7%,居民储蓄倾向增强。2001年股市波动性加大,股价持续几个月的大幅回调,则是2001年储蓄分流减缓、居民储蓄存款大幅增加的主要原因之一。

另外,利率对于企业的经营成本影响同样需要一个生产和销售的资本运转过程,短时间内,难以体现出来。因此,利率和股票市场的相关性要从长期来把握。

实际上,就中长期而言,利率升降和股市的涨跌也并不是简单的负相关关系。就是说,中长期股价指数的走势不仅仅只受利率走势的影响,它同时对经济增长因素、非市场宏观政策因素的反应也很敏感。如果经济增长因素、非市场宏观政策因素的影响大于利率对股市的影响,股价指数的走势就会与利率的中长期走势相背离。

典型如美国的利率调整和股市走势就出现同步上涨的过程。1992年至1995年美元加息周期中,由于经济处于稳步增长阶段,逐步收紧的货币政策并未使经济下滑,公司盈利与股价走势也保持了良好态势,加息之后,股票市场反而走高,其根本原因是经济增长的影响大于加息的影响。

我国从1996年5月进入降息周期的拐点。股指也进入上升周期。利率与股指的走势发生了5年的负相关关系。但2001年在利率没有进入升息周期的情况下,股指开始了下跌的趋势。分析其原因,我国非市场宏观政策因素的影响大于利率对股市的影响。人们对非流通的国有股将进入市场流通的担心和恐惧导致了股市投资的风险和收益发生了非对称的变化。从这个角度来看,由于我国目前非市场宏观政策因素仍然有比较大的不确定性,所以利率对股市的影响不能够成为我们研究和预测股市中长期走势的主要因素。

就短期而言,我国利率的变动对股价的走势很难判断存在相关性。利率调整当天和随后的股价波动并不能说明二者之间有何必然的联系。从当前股市的状况分析,很明显也和利率的走势不符合理论上的负相关性。股票市场的低迷更多地被归结为上市公司的质量以及诸多体制性问题和投资者信心问题。因此,在看待我国加息预期对于股票市场的影响时,还要考虑其他诸多因素,而不能简单从前文所述的理论关系来判断。利率只是影响股市的因素之一,而不是惟一决定因素。因此,我们不能唯利率升降是从,要具体分析,何况即使利率上升,股市也并不是就完全没有投资机会。（

Interest rates. Most people pay attention to them, and they can impact the stock market. But why? In this article, we'll explain some of the indirect links between interest rates and the stock market and show you how they might affect your life.

The Interest Rate
Essentially, interest is nothing more than the cost someone pays for the use of someone else's money. Homeowners know this scenario quite intimately. They have to use a bank's money (through a mortgage) to purchase a home, and they have to pay the bank for the privilege. Credit card users also know this scenario quite well - they borrow money for the short term in order to buy something right away. But when it comes to the stock market and the impact of interest rates, the term usually refers to something other than the above examples - although we will see that they are affected as well. (To read more, see Who determines interest rates?)

The interest rate that applies to investors is the U.S. Federal Reserve's federal funds rate. This is the cost that banks are charged for borrowing money from Federal Reserve banks. Why is this number so important? It is the way the Federal Reserve (the "Fed") attempts to control inflation. Inflation is caused by too much money chasing too few goods (or too much demand for too little supply), which causes prices to increase. By influencing the amount of money available for purchasing goods, the Fed can control inflation. Other countries' central banks do the same thing for the same reason.

Basically, by increasing the federal funds rate, the Fed attempts to lower the supply of money by making it more expensive to obtain.(To see more on the Federal Reserve, read Get To Know The Major Central Banks, The Fed Model And Stock Valuation: What It Does And Does Not Tell Us and Formulating Monetary Policy.)

Effects of an Increase
When the Fed increases the federal funds rate, it does not have an immediate impact on the stock market. Instead, the increased federal funds rate has a single direct effect - it becomes more expensive for banks to borrow money from the Fed. However, increases in the discount rate also cause a ripple effect, and factors that influence both indivials and businesses are affected.

The first indirect effect of an increased federal funds rate is that banks increase the rates that they charge their customers to borrow money. Indivials are affected through increases to credit card and mortgage interest rates, especially if they carry a variable interest rate. This has the effect of decreasing the amount of money consumers can spend. After all, people still have to pay the bills, and when those bills become more expensive, households are left with less disposable income. This means that people will spend less discretionary money, which will affect businesses' top and bottom lines (that is, revenues and profits).

Therefore, businesses are also indirectly affected by an increase in the federal funds rate as a result of the actions of indivial consumers. But businesses are affected in a more direct way as well. They, too, borrow money from banks to run and expand their operations. When the banks make borrowing more expensive, companies might not borrow as much and will pay a higher rate of interest on their loans. Less business spending can slow down the growth of a company, resulting in decreases in profit. (For extra reading on company lending, read When Companies Borrow Money.)

Stock Price Effects
Clearly, changes in the federal funds rate affect the behavior of consumers and business, but the stock market is also affected. Remember that one method of valuing a company is to take the sum of all the expected future cash flows from that company discounted back to the present. To arrive at a stock's price, take the sum of the future discounted cash flow and divide it by the number of shares available. This price fluctuates as a result of the different expectations that people have about the company at different times. Because of those differences, they are willing to buy or sell shares at different prices.

If a company is seen as cutting back on its growth spending or is making less profit - either through higher debt expenses or less revenue from consumers - then the estimated amount of future cash flows will drop. All else being equal, this will lower the price of the company's stock. If enough companies experience a decline in their stock prices, the whole market, or the indexes (like the Dow Jones Instrial Average or the S&P 500) that many people equate with the market, will go down. (To learn more, check out Why Do Markets Move?, Forces That Move Stock Prices and What causes a significant move in the stock market?)

Investment Effects
For many investors, a declining market or stock price is not a desirable outcome. Investors wish to see their invested money increase in value. Such gains come from stock price appreciation, the payment of dividends - or both. With a lowered expectation in the growth and future cash flows of the company, investors will not get as much growth from stock price appreciation, making stock ownership less desirable.

Furthermore, investing in stocks can be viewed as too risky compared to other investments. When the Fed raises the federal funds rate, newly offered government securities, such Treasury bills and bonds, are often viewed as the safest investments and will usually experience a corresponding increase in interest rates. In other words, the "risk-free" rate of return goes up, making these investments more desirable. When people invest in stocks, they need to be compensated for taking on the additional risk involved in such an investment, or a premium above the risk-free rate. The desired return for investing in stocks is the sum of the risk-free rate and the risk premium. Of course, different people have different risk premiums, depending on their own tolerance for risk and the company they are buying. However, in general, as the risk-free rate goes up, the total return required for investing in stocks also increases. Therefore, if the required risk premium decreases while the potential return remains the same or becomes lower, investors might feel that stocks have become too risky, and will put their money elsewhere.

Interest Rates Affect but Don't Determine the Stock Market
The interest rate, commonly bandied about by the media, has a wide and varied impact upon the economy. When it is raised, the general effect is to lessen the amount of money in circulation, which works to keep inflation low. It also makes borrowing money more expensive, which affects how consumers and businesses spend their money; this increases expenses for companies, lowering earnings somewhat for those with debt to pay. Finally, it tends to make the stock market a slightly less attractive place to investment.

Keep in mind, however, that these factors and results are all interrelated. What we described above are very broad interactions, which can play out in innumerable ways. Interest rates are not the only determinant of stock prices and there are many considerations that go into stock prices and the general trend of the market - an increased interest rate is only one of them. Therefore, one can never say with confidence that an interest rate hike by the Fed will have an overall negative effect on stock prices.

『叁』 股票交易里，成交额排名是什么意思成交额是指买入和卖出吗成交额排前的股票有什么优势

对交易所来说，成交必然是有一个买入另一个卖出的结果，所以这个金额就是单方的金额，其实买和卖的金额是一样的，算一个即可。
成交额排名是交易所对股票的成交金额进行统计后得到的，成交额排前的股票一是大盘股，它们的股份数量大，成交金额自然多；二是当天的热门股，成交活跃，成交量也就大了。

『肆』 关于股票成交金额的问题，到底是=买入+卖出，还是=买入或卖出额

第一个问题，买就是卖，卖就是买，所以你的猜想是正确的。第二个问题，买入比例，指的是买入金额和成交金额的比例。注意看这个交易公开信息，是连续三个交易日的。11.8亿仅仅是当天的，需要把连续三个交易日的成交金额都加上。

『伍』 股票成交额是什么意思能说明什么事情

简单地说，交易量是指交易的股票手数、换手率和交易量之间的关系；成交量是指交易量、所有买卖的金额以及股票价格和股票交易量之间的关系。这两个概念实际上是一回事，但形式不同。您可以计算买方购买股票时的交易金额和卖方出售股票时的交易金额。这两个数字都很大，说明股票交易活跃，换手率大。如果这个数字很小，这表明交易很枯燥。你认为股票交易量怎么样？成交量的上升和成交量的下降表明股票价格处于较低水平。通常，股票价格呈下降趋势。

当股票涨停时，交易量越小，卖出价格越低，卖出压力越小，继续涨停的可能性越大。对于交易量巨大的交易限额，我们应该观察交易是发生在交易限额之前还是之后。上升和放大代表着阻止庄逃跑的潜力；衰退的扩大意味着衰退并不强烈。同样，庄师傅也不应该建仓库。如果是高水平和大规模的下跌，则更有可能是主要的分销和发货；如果是低成交量、连续成交量或巨额成交量，预计下跌将放缓，短期内可能反弹。

『陆』 股票成交额是怎么算的

计算公式

买入（卖出）金额=成交金额+交易费

=成交金额+佣金+印花税+过户费+手续费

=成交金额+成交金额×佣金率+成交金额×印花税率+其它费

=成交金额×（1+费率）+其它费

=成交单价×成交股数×（1+费率）+其它费

=持仓单价×成交股数+其它费

=持仓金额+其它费

其中，

成交金额=成交单价×成交股数

佣金=成交金额×佣金率

印花税=成交金额×印花税率

费率=佣金率+印花税率

其它费=过户费+手续费

过户费=成交股数×过户费率

手续费=5元/笔

持仓单价=成交单价×（1+费率）

持仓金额=持仓单价×成交股数

=成交单价×（1+费率）×成交股数

(6)可变利率投资组合股票成交额扩展阅读：

1、交易费用

交易费用，可简称为交易费。又分为买入交易费用和卖出交易费用。

（一）买入交易费用：可简称为买入交易费，是指投资者买入股票时需支付给有关机构的费用。包括，佣金、印花税、过户费和证券公司收取的手续费。

（二）卖出交易费用：可简称为卖出交易费，是指投资者卖出股票时需支付给有关机构的费用。也包括，佣金、印花税、过户费和证券公司收取的手续费。

但与买入交易费不同的是，由于，买入股票时，买入交易费是将其加入到买入金额中，因此，其取值为正。

而卖出交易费，由于卖出股票时，卖出交易费是要从卖出金额中减去，因此，取值为负。另外，目前由于印花税采取单向收取方式，即买入股票时不收取；卖出股票时才收取。因此，两者也不相同。

为了简化起见，可将两者统称为交易费。其单位为元。但是，必须注意的是，如前所述两者的区别。

2、成交数量

成交数量可分为买入成交数量和卖出成交数量，两者统称为成交数量或成交股数。成交数量是指买入或卖出股票时，股票成交的股数。其单位为股。

3、成交单价

成交单价也可分为买入成交单价和卖出成交单价，或简称为买入单价和卖出单价。为了简化起见，两者可统称为成交单价。成交单价是指买入或卖出股票时每股的成交价格，其单位为元/股。

4、佣金

佣金是证券交易所收取的费用，其单位为元。

5、印花税

6、印花税是国家收取的税费，其单位为元。

7、过户费

过户费是证券交易所收取的一种费用，其单位为元。

8、证券公司收取的手续费

该费用通常按每笔固定收取5元。

9、其它费

由于，佣金和印花税都与成交金额有关，而过户费和证券公司收取的手续费与成交金额无关，因此，有时将过户费和证券公司收取的手续费之和统称为其它费。

『拾』 利率变动对股价有何影响

在股票投资中，影响股票的因素非常多，例如公司的营业收入、行业政策、公司的行业地位、当前的产品的供需情况等等，但是在不可否认，利率调整对股市的影响至关重要。

1、利率上升：当市场的利率上市时，它会通过两个方面影响股市的走势。一方面，利率上升，企业的融资成本增加，财务费用的开支也会同步增加，导致企业扩张的意愿下降，在原有的营业收入维持不变的情况下，费用的增加会导致净利润的下降，公司的市值也会同步下降。另一方面，当利率上升时，以债券为代表的固定预期收益理财产品的吸引力对投资者显著增加，原先投资股票市场的资金会逐渐转向到固定预期收益理财，导致市场的成交量不足，股市的上涨动能不足，有可能导致股市大盘回调。

2、利率下降：实际上，利率下降也是通过减少企业的融资成本和增加市场的货币资金投向，来进一步影响股市大盘的具体走势。利率下降，企业融资成本下降，净利润上升，企业的市值上涨。利率下降，投资固定预期收益的资金减少，投资股票市场的资金增加，导致市场的整体成交量上涨，为大盘上涨注入新鲜活力。
