道琼斯指数的除数

美国道琼斯指数的变化及大事记一道琼斯指数的由来及发展1.1 美国股市的起源1792年，24名纽约经纪人在纽约华尔街的一棵梧桐树下订立协定，约定以后每天都在此进行股票等证券的交易。

1817年，由于市场日渐活跃，于是参加者组成了纽约证券交易管理处。

1863年，它正式更名为纽约证券交易所。

这便是美国股市的起源。

1.2 道琼斯指数1.2.1 道琼斯的由来1882年，道（Dow）与好友琼斯（Jones）在华尔街15号创办了道琼斯公司。

1884年7月3日，道为了追踪股票市场推出了一项包含十一种股票的指数。

其中包括九家铁路公司和两家汽轮公司的加权平均价格。

1889年7月8日，《华尔街日报》诞生了。

一百年后，道提出的平均指数以及登载它的《华尔街日报》不但影响到整个华尔街，而且还影响了整个世界。

1896年5月26日，道第一次计算并对外公布了道琼斯工业平均数（DJIA），当日指数为40.94。

为了适应科技进步与股市发展的需要，现今道指30只成份股已不再局限于传统定义的工业股，如今的道指取样已经覆盖了整个美国股市中最优秀的蓝筹股，并包含了金融服务、科技、零售、娱乐以及生活消费品等多种行业。

作为样本，它们是各个行业的龙头或代表，这些样本股拥有最广泛的个体投资者和机构投资者。

1.2.2 道指的发展一、30年代大萧条“吃掉”道指33年的“积累” 1896年5月26日，道指（DJIA）从40.94点艰难起步。

1929年9月3日，道指收至历史最高点位381点。

20年代的定金交易使得全美国人都能像金融大腕们一样投资股票，甚至擦鞋匠都在投资。

这一时期也是美国走向世界霸主地位的重要转折时期。

在这一阶段，美国股市一路顺风，然而，正当美国人民沉浸在繁荣与幸福之中不能自拔时，一场历史上罕见的大危机正在悄悄逼近美国人民。

1929年的经济大崩盘开始于10月24日星期四的抛售狂潮，结束于10月29日的彻底崩溃。

人们永远也不会忘记那一个“黑色星期二”，10年的发展在几天之内毁于一旦，道琼斯指数下跌了24％，几十亿美元一下子全消失了。

国际上主要股票指数历史走势及成因分析一、道·琼斯股票价格指数道·琼斯指数是迄今为止历史最悠久、影响范围最广的股票指数，从开始编制至今 100 多年来从无间断。

1884 年 6 月 3 日，道·琼斯公司创始人查尔斯·道开始编制一种股票价格指数，并刊登在《每日通讯》上。

今天的道·琼斯指数发表在《华尔街日报》上，共分四个分类指数：工业股票价格指数、运输业股票价格指数、公用事业股票价格指数和综合股票价格指数。

其中，工业股票价格指数应用范围最广。

在这四类指数下又有若干的细分指数，总量达到 300 多种。

道·琼斯工业、运输业和公用事业股票指数都是平均系列指数，综合指数是由以上三个指数的 65 只成份股组成的平均指数，可以综合反映纽约证券交易所所有上市股票的价格总体走势。

道·琼斯平均指数采用算术平均法计算，遇到拆股、换牌等非交易情况时用除数修正法予以调整。

美国道琼斯指数历史走势道琼斯 30 种工业股票平均价格指数于 1896 年 5 月 26 日问世，百年来趋势分析如下：1 、 1920 年一战后，商品泡沫破灭，通货紧缩开始，迎来了股市大牛市场。

到1929 年 9 月 3 日 , 道·琼斯股票指数达到 20 年代的高峰。

1929 年 9 月至 1932 年 6 月 , 美国经济危机，道·琼斯指数下跌了 89% ，1929 年 10 月 28 日，美国股灾，日跌幅达 13% 。

美国 1929-1932 年经济危机的起因是房地产泡沫，按揭庞大，无力偿还，发生了银行金融危机。

2 、 1932 年 7 月至 1937 年 2 月，道·琼斯指数回升，整个这一时期的升幅为 337% 。

当时，罗斯福新政，美国经济开始复苏。

1949 年 6 月至 1966 年 1 月，该指数在二战后上升了 487% 。

二战后商品及通胀泡沫破灭， 1950 年，制止通货膨胀跟至，艾森豪威尔股市牛市开始。

道指除数计算公式
道指除数（Dow Divisor）是用于计算道琼斯工业平均指数（Dow Jones Industrial Average, DJIA）的一个关键数值。

道琼斯工业平均指数是一个价格加权指数，它衡量的是30家大型美国公司的股票价格。

然而，由于股票分割、股息支付、公司替换等原因，直接使用这些公司的股票价格来计算平均数是不准确的。

因此，道指除数被引入来作为一个调整因子，确保指数的历史连续性。

道指除数的计算公式并不是直接给出的，因为它是由道琼斯公司的专家根据一系列复杂的因素来定期调整的。

然而，我们可以理解道指除数是如何影响道琼斯工业平均指数的计算的。

道琼斯工业平均指数（DJIA）的计算公式大致如下：
DJIA = (ΣP) / 道指除数
其中，ΣP 表示30家成分股的价格之和。

道指除数是一个小于1的数，它的作用是调整股票价格的总和，以反映股票分割、替换、股息支付等因素对指数的影响。

如果没有这些调整，指数的历史比较就会变得困难，因为股票价格的绝对变化会掩盖其相对表现。

道指除数是由道琼斯公司的指数委员会定期调整的，以确保指数
的连续性和可比性。

这些调整通常是在股票分割、股息支付、公司替换等事件发生后进行的。

需要注意的是，由于道指除数是道琼斯公司的专有信息，普通投资者无法直接计算或获取其精确值。

我们只能通过观察道琼斯工业平均指数的变化来间接了解道指除数的影响。

道琼斯指数计算例子
【篇一：道琼斯指数计算例子】
道琼斯股票价格平均指数最初的计算方法是用简单算术平均法求得，当遇到股票的除权除息时，股票指数将发生不连续的现象。

1928年后，道琼斯股票价格平均数就改用新的计算方法，即在计点的股票
除权或除息时采用连接技术，以保证股票指数的连续，从而使股票
指数得到了完善，并逐渐推广到全世界。

现在的道琼斯股票价格平均指数是以1928年10月1日为基期，因
为这一天收盘时的道琼斯股票价格平均数恰好约为100美元，所以
就将其定为基准日。

而以后股票价格同基期相比计算出的百分数，
就成为各期的股票价格指数，所以现在的股票指数普遍用点来做单位，而股票指数每一点的涨跌就是相对于基准日的涨跌百分数。

计算公式为：
股票价格平均数=入选股票的价格之和/入选股票的数量
【篇二：道琼斯指数计算例子】
1. 股价平均数的计算股票价格平均数反映一定时点上市股票价格的
绝对水平，它可分为简单算术股价平均数、修正的股价平均数、加
权股价平均数三类。

人们通过对不同时点股价平均数的比较，可以
看出股票价格的变动情况及趋势。

30元，计算该市场股价平均数。

将上述数置入公式中，即得：股价平均数＝(p1＋p2＋p3＋p4)/n ＝
（10＋16＋24＋30）/4 ＝20(元)
【篇三：道琼斯指数计算例子】。

道琼斯指数除数
道琼斯指数是由30只美国企业的股票组成的股票指数。

而这30只股票的价格总和并不等于道琼斯指数的值，这是因为道琼斯指数使用了一种特殊的加权平均算法来计算其值。

而这个加权平均算法的核心就是指数的“除数”。

道琼斯指数除数是一个常数，用于抵消道琼斯指数中股票价格总和与实际指数值之间的差异。

除数的取值在指数的计算过程中是固定的，但它会随着股票分拆、合并、红利等因素的发生而偶尔进行调整。

目前，道琼斯指数的除数约为0.152。

除数的意义在于保证道琼斯指数的连续性和可比性。

如果不使用除数，道琼斯指数的值将会随着股票价格变化而不断波动，难以进行比较和研究。

而通过使用除数，道琼斯指数的变化趋势可以更加明显地展现出来，同时也方便了投资者对市场的分析和决策。

道琼斯指数，又可以叫作“道琼斯股票价格平均指数”，可以用“$US30”表示。

它
是在1884年由道琼斯公司的创始人查尔斯·亨利·道编制的一种算术平均股价指数，可以说是世界上历史最悠久的股票指数，同时也是世界上最有影响、使用最广的股价指数。

道琼斯股价指数由四种股价平均指数构成，分别是：
1.以30家著名的工业公司股票为编制对象的道琼斯工业股价平均指数；
2.以20家著名的交通运输业公司股票为编制对象的道琼斯运输业股价平均指数；
3.以15家著名的公用事业公司股票为编制对象的道琼斯公用事业股价平均指数；
4.以上述三种股价平均指数所涉及的65家公司股票为编制对象的道琼斯股价综
合平均指数。

而在这四种道琼斯股价指数中，最著名的就是第一种道琼斯工业股价平均指数了。

人们通常所说的道琼斯指数也正是指道琼斯工业平均指数。

《证券投资学》参考资料――股票交易市场之道一琼斯股票指数
道一琼斯股票指数全称为道一琼斯股票价格平均指数。

是世界上最早的最有影响的股票价格指数。

道一琼期指数是查尔斯•享利•道和爱德华•琼斯，在1884年7月3日计算并发表在《客户午后快汛》上的。

最早的道一琼斯指数只包括11种股票，其中9种是铁铝股票到了1938年达65种。

这65种股票包括四组指数：①30种工业股票平均指数。

包括全国最大的最有代表性的工商业公司。

－般提到的道一琼斯指数就是指这个指数，这是一个作用更突出的指数。

②20种运输业股票平均指数。

③公用事业股票平均指数。

根据15家最大的公用事业股票编制。

④65种工业股票平均指数。

这个指数更能反映股票市场的变化趋势。

道一琼斯指数的计算方法是，以1928年10另1日为基期、基期为100，报告期与基期相比乘100，即为报告期指数。

从1928年起采取除数修正法，以维持股指的连续性。

道琼斯指数（Dow Jones index）The Dow Jones Indexes Dow Jones index is an arithmetic average stock index. The Dow Jones index is the oldest stock index in the world, and its full name is the stock price average. Usually, the Dow Jones index is probably the first Average group in the Dow Jones index (Dow Jones Industrial).The Dow Jones index was first compiled by Charles Doug, founder of the Dow Jone am Co in 1884. The Dow Jones average stock price index is based on the 11 representative railway companies calculate was compiled using the arithmetic mean method, published in Charles Doug's own editor published in the "Daily" on communication. The formula is: the average of the stock price = the sum of the selected shares and the quantity of the selected sharesDow Jones indexThe index aims to reflect the general trend of the U.S. stock market, covering financial, technology, entertainment, retail and other industries.Editor's note Dow Jones Industrial AverageThe Dow Jones Industrial Average currently consists of the "Wall Street journal" editorial department of maintenance, the selection criteria of its constituent stocks including sustainable development companies, large scale, high reputation, representative of the industry, and for the majority of investors.

To date, only Ge remains in the index in the 12 components. The remaining 11 are listed below (in the order of the company's English name):The United States cotton oil manufacturing company, formerly known as Bestfoods, is now part of Unilever's American sugar company, now Amstar Holdings, the American Tobacco companies,In 1911 for violating antitrust law was forced to split Chicago Gas Co, in 1897 was acquired by Peoples Gas Light & Coke Co. (now the people's energy company) Distilling & Cattle Feeding Company, Millennium Chemicals Laclede Gas is Light Company The Laclede Group, still with the name National Lead operation Company, now NL Industries company in North America. In 1940s the bankruptcy of Tennessee coal and iron and railway company, in 1907 by the American Iron and steel American Fur Company's dissolution in 1952 U.S. rubber company, in 1967 changed its name to Uniroyal (2000: Uniroyal), acquired by Michelin in 1990 when it was first released when the index was 40.94. It is calculated as an average index, first of all the prices of all the constituent stocks, and then divided by the number of shares. In 1916, the number of stocks in the Dow Jones industrial average increased to 20, the last in 1928 increased to 30. By November 14, 1972, the average was above 1000 points for the first time (1003.16 points). After 1980s, especially in 1990s, you can see a very rapid growth in the average index.

By October 9th, it fell below 9000.The Dow Jones Industrial Average biggest one-day percentage decline occurred in the "black Monday" in 1987, when the average index fell 22.6%. The biggest one-day point decline occurred in September 29, 2008, when the Dow Jones Industrial Average fell 777.68 points to close 10365.45 points. But then a series for subprime mortgages because of financial policy innovation, in October 13, 2008 the largest single day record inflation record. The Dow Jones industrial index rose 936.42 points to close 9387.61 points.Edit this section of the Dow Jones index founderCharles Henry Doug, a small farmer who has only been a primary school student, has become an excellent financial journalist by self-study. Edward Davis Jones, graduated from BrownUniversity, was as grumpy as his red beard showed. Charles Milfort Bergstrice, because the surname is too long, lost forever in the history of the opportunity. In November 1882, two young reporters Charles Doug and Edward Jones Dow Jone am Co was established in 15 Wall Street, a small office, then all their belongings only a typewriter and a phone,. The company's first business is only two pages of evening news. The text of the customer evening news is about stock market related information. In the early days, in order to save money, the two managers can only copy the evening paper, 24 copies of poor paper. Soon after the company was founded,Third partner journalist Charles Bergstrice joined, but the company name did not change. In 1884, they launched an index containing 11 stocks. Among them, the average price of 9 railway companies and 2 steam turbine companies, which is also the prototype of the Dow Jones index. In July 8, 1889, the evening paper changed to the Wall Street journal, which specializes in reporting stock information. In May 26, 1896, Charles Doug's Wall Street journal published the first average price index for 30 industrial stocks, the Dow Jones index, which is often called the Dow Jones index. In March 1902, Dow Jone am Co sold Clarence Byron, a news mogul, for $130 thousand. Charles died in the same year, but the stock index he founded has been a profound influence on the world economy, and has continued so far.
