wholesale gold crystal jewelry my country's stock market index refers to the "Shanghai Comprehensive Index" of the Shanghai Stock City and the "Shenzhen Stock Exchange Stock Index" in Shenzhen. SSE Comprehensive Index: Taking all stocks (including A shares and B shares) listed on the Shanghai Stock Exchange as a sample, the issuance of issuance is the right (including the circulating share capital and the non -tradable share capital), the weighted average method is calculated. December 19 is the base day, and the base day index is set to 100 points of the stock price index. Shenzhen Stock Exchange Establishment Estate Index: Those who are listed listed on the Shenzhen Stock Exchange are drawn from all stocks listed on the market. On the 20th, the base day index is set as a stock price index of 1000 points.
luxury jewelry wholesale Stock index = (total stock market value of the day ÷ total stock market price of the base period) × 100 × 100 is calculated by all stocks, and there are some other arithmetic methods.
(1) Arithmetic stock price index method. The arithmetic stock price index method is based on a trading day as the base period. The countdown of the number of sample stocks is multiplied by the comparison of the price of each sample stock price and the base price. For: arithmetic stock price index = 1 / Collect number of sample stocks × ∑ × × (Chen complaint price / base price price) × basal period index value
(2) arithmetic average method. It is to calculate the arithmetic average of all samples in this stock index.
The average number of arithmetic of the stock price = (the total price per share of the sampling stock) ÷ (the number of sampling stock categories) then, then the calculated average is compared with the average period obtained from the same law. The stock price index of the period, that is, the stock price index = (current stock price analogy) ÷ (the average of the basal stock price arithmetic) × 100%.
(3) The weighted average method. It is the weighted average of all samples in this stock index. Usually the number of authority is allocated based on the total market value of each stock or the total number of listed shares traded at that time. The stock price index of most countries in the world is calculated by the weighted average method, such as 300 stock price indexes such as the US standard Pur index and the Tokyo Stock Exchange Index.
(4) Division of revision method. Also known as the Daojin Fa, it is a method of calculating the average stock price invented in 1928 to overcome the shortcomings of the simple average law. The core of this method is to find a constant division to correct the changes in the total amount of stock price caused by factors such as paid capital increase and stock support, which truthfully reflects the average stock price.
The calculation formula is: Taoist divisor = new stock price after change / the average of the average stock price of the old stock price of the old stock price = the total stock price of the complaint period / the division of the road
Amendment method:
1. The intention of this method is due to the incident of capital increase, listing of new shares, or abolition of listing, etc., which will cause changes in the total number of listed shares and cause the total stock price. , Corresponding mediation of the stock price of the base period must be made.
2, the formula is: the basis of the basis of the basis = the total amount of the original period × the total amount of the stock price after the number of stocks is changed / the total amount of the stock price before the transformation of the listed stock.
wholesale jewelry cardboard boxes The stock price index is obtained by calculating the total value of the stock market price of the sample stock market.
The stock price index (Stock
index) is an indicator describing the total price level of the stock market. It is a representative set of stocks that weigh their prices for average and can be obtained through certain calculations. The selection and calculation methods of various indexes are different.
The calculation method of the stock index
1. Relative method
The relative method is also called the average method, which is to calculate the various stock indexes first. Coupled with the total arithmetic average. The calculation formula is:
stock index = N
The general stock index of the British "Economist" ordinary stock index uses this algorithm.
2. The comprehensive method
The comprehensive method is to sum up the base period and reporting period of the sample stock first, and then compare the stock index. That is:
The sum of the stock price of the reporting period/the sum of the stock price of the reporting period
substitating the number:
stock price index = (8 12 14 18)/(5 8 10 10 10 15)
=
52/38 = 136.8%
is that the stock price of the reporting period increased by 36.8%from the base period.
In the general method and comprehensive method calculation of the stock index, neither of the two considers the differential amount and transaction volume of various sampling stocks, but the impact on the stock market price of the entire stock market is different. The calculated index is not accurate enough. In order to make the stock index calculation accurately, the number of rights needs to be added. The number of rights can be transaction volume or circulation.
3. The weighted method
The weighted stock index is weighted according to the relative importance of sample stocks. Divided by time, the number of authority can be the number of basis rights or the number of reporting options. The index with the number of rights (or issuance) of the basis of the basis is called the Lasbiel Index; the index with the number of rights (or issuance) with the number of transactions (or issuance) is called the fabric index. For the geometric average of the Lasbier index and the faction index, the geometric weighted stock price index "Fei Xue ideal".
The Lasbier index focuses on the number of stocks (or circulation) in the base period, while the fabric index focuses on the number of transactions (or issuance) of the reporting period. Most of the current stock indexes in the world are fabricated index.
definition and principle
The stock price index is an indicator to reflect the overall level of various stock market prices in the entire stock market and its changes. Referred to as the stock index. It is a reference number that shows changes in the stock market by the stock exchange or financial service agency. Due to the ups and downs of stock prices, investors must face market price risks.
For the price changes of a specific stock, investors are easy to understand, and the price changes of multiple stocks must be understood one by one. It is neither easy nor annoyed. In order to adapt to this situation and needs, some financial service institutions use their business knowledge and familiarity with the advantages of the market to prepare the stock price index, such as Daofu Investment and Public release as an indicator for market price changes. Investors can test the effects of their own investment and predict the movement of the stock market. At the same time, the press and company owner also used this as a reference indicator to observe and predict the economic development situation.
It calculates the average stock price or index. The following four points are often considered:
(1) Sample stocks must be typical and ordinary. To this end, the selection of samples should consider its industry distribution, market influence, and market influence, and Factors such as stock levels and appropriate quantities.
(2) The calculation method should be highly adaptable, which can make corresponding
stock price indexes
adjustment or correction to make the stock index or average. Sensitivity.
(3)
The scientific calculation basis and means. The caliber of the calculation basis must be unified, and the closing price is generally calculated. However, as the calculation frequency increases, some are calculated at a time price of each hour or even shorter.
(4)
This should have good equilibrium and representative period.
fashion jewelry wholesale near me 1. According to the definition, the stock index is the average stock price. However, from the actual role of the two in the stock market, the average of the stock price reflects the general level of changes in multiple stock prices, which is usually expressed at an arithmetic average.
2. Through comparison of the average stock price of different periods, people can understand the level of changes in multiple stock prices. The stock index is a relative indicator that reflects the changes in the stock price in different periods, that is, the percentage of the average stock price of the first period as the basis for the average stock price in the first period. Through the stock index, people can understand the percentage rate of the stock price of the calculation period than the stock price in the base period. Because the stock index is a relative indicator, for a long period of time, the stock index can more accurately measure the changes in the stock price than the average stock price.
wholesale little girl jewelry The stock price index is compiled by the index method in statistics, which reflects the overall price of the stock market or the changes and trends of some types of stock price.
The scope covered by the price trend reflected in the stock price index can be divided into a comprehensive index that reflects the entire market trend and a classification index that reflects a certain industry or a certain type of stock price. For example, the Hang Seng Index reflects the overall trend of the Hong Kong stock market, and the Hang Seng State -owned Enterprise Index reflects the price trend of the Japanese stocks listed in Hong Kong and the Hang Seng Red Chips Index reflects the price trend of the Hong Kong stock market. According to the number of stock samples incorporated into the calculation range of the index when the stock price index is compiled, the stock price index can be divided into all the Chinese stock price indexes and the ingredient stock index. The former refers to incorporating all the stocks involved in the price trend reflected in the index into the index calculation range. For example, the comprehensive index of the Shanghai Stock Exchange issued by the Shanghai Stock Exchange is to incorporate the price changes of all listed stocks into the calculation range. Shanghai Securities Securities Securities The industry stock price index, the commercial stock price index, etc. will include all industrial listed stocks and commercial listed stocks into their respective index calculation range, respectively. The Chengfen Stock Index refers to selecting a part of the more representative stocks from all the stocks covered by the index as an index sample, which is called the index's ingredients. When calculating, only the selected component stocks are included in the index H calculation range. For example, the Shenzhen Securities Trading Listening to the Ingredient Stock Index is a comprehensive constituent stock index that is selected from all listed stocks on the Shenzhen Stock Exchange. Through this index, the price trend of the coordinarian listing shares can be reflected closely. The industrial stock index issued by the Shenzhen Stock Exchange is from the Shenzhen Stock Exchange. The Chuanjia ingredients stocks were selected as the representative of the industrial stocks of Bu City. When preparing the ingredient index, in order to ensure that the selected samples are fully representative, the international practice is to comprehensively consider the proportion of the total market price and transaction volume of sample stocks in all listed stocks. It is necessary to fully consider the industry's industry representativeness. After the index is announced, it is necessary to change the sample stock regularly according to market changes.
The calculation method of the stock price index, there are two types of arithmetic average method and weighted average method. The average method of arithmetic is to make a simple average of each stock price of the constituent index, and calculate a average value. E.g. If the calculated stock index includes 3 stocks, the price is 15 nifevity, 20 yuan, and 30 yuan, the average stock price arithmetic is (15 20 30) / 3=21.66 yuan. The weighted average method is to consider the price of each stock when calculating the average of the stock price, but also adjust the average value according to the impact of the market in each stock. In practice, generally uses the number of stocks or trading volume as the market impact reference factors, and is included in the index calculation, which is called the number of rights. For example, the number of issues of three shares in the previous examples is 100 million, 200 million, and 300 million shares, respectively. As for the weight calculation, the average price of the price is (15x1 20x2 30x3) / (1 2 ＋ 3): 24. 16 yuan.
Because the actual average price of the stock is not convenient for people to calculate and use it, it is generally rarely used to use the average price to watch the water index level. Instead, the average price of a benchmark date is based on the average price of each period and the average price of the benchmark date in the future. Calculate the comparison of each period. Then convert to a percentage or a thousand points. Taking this as the value of the stock price index. E.g. The comprehensive index reference date index issued by the Shanghai Stock Exchange and Shenzhen Stock Exchange is 100 points, while the benchmark date index released by the two component indexes is 1000 points.
In practice, listed companies often have capital increase, stock demolition, dividend and other behaviors, so that stock prices have dividends and dividend effects. Lost continuity. Can't directly compare. Therefore, when calculating the stock price index, you must also consider the changes in these factors and correct the index in time to avoid distortion of the stock price index.
