Beginners learn well. When I was just getting started, I also read books to understand the stock market and then used Niu Gubao simulation software for in-depth study and research, which accelerated the learning progress.
What do individual stocks and indexes in stocks mean?
For example, if you start a company with two friends, you pay 200,000 yuan, and they each pay 654.38+ 10,000 yuan. In this way, your company has a total investment of 400,000 yuan, and you enjoy 50% of the shares, and they each hold 25% of the shares. Your company has three shareholders.
So the so-called equity is a person's share right in the enterprise. This right includes decision-making right and dividend right. Decision-making power is the weight of his speech, and the decision-making power with more shares is greater. Dividend right is the right to distribute profits according to the proportion of shares. The bigger the shares, the more dividends.
If the above-mentioned shares are printed on a piece of paper to become a certificate, it is printed with: What is the percentage of shares held by a certain company? This kind of certificate is called stock.
Therefore, stock is only a form of equity. Just as you are hired by your work unit and given a work permit to prove that you are an employee of the unit, if you are given shares, it will prove that you are a shareholder of the company.
A listed company means that its shares can be bought and sold in the market. Therefore, at this time, the name of the owner is not printed on the stock of this company.
In addition, if you buy shares of a company in Nanning, Guangxi, and you are in Beijing, it will be very troublesome for their company to mail you 100 shares. Besides, in a few days, you may sell your stock to others. Therefore, listed companies will not send this printed stock to ordinary shareholders, and they can use the records in the computer instead. So, if you buy a company's stock, it is recorded in the computer of the securities company.
Therefore, when you buy the company's shares, you have the right to attend its shareholders' meeting and participate in dividends. Of course, if you sell the stock before the dividend is paid, you won't get any dividend. Hmm. How interesting
The so-called stock trading is to open an account in any securities company and become a so-called stockholder, so you can buy and sell stocks at will in the stock market. You bought 100 shares at10 yuan/share, which means you spent 1000 yuan. In a few days, if it rises to 1 1 yuan/share, you can sell it again, and you will get 1 100 yuan, and you will make money. Of course, you have to pay a little handling fee. But if this stock falls and the price becomes 9 yuan/share, you will lose money if you sell it. However, it may never go up again, and you won't make any money. This is the risk of the stock market.
Because the total number of shares circulating in the market of a listed company is fixed, except when the company issues shares for the first time, everyone gives money to buy shares for the company. At other times, the stock you buy is the stock sold by others. If the stock goes up after you buy it, you are lucky and he is sorry. On the other hand, after you bought the stock, the stock fell, you lost money, and he escaped.
The operation principle of the stock market is simple: buy low and sell high. However, this is difficult to do.
There are too many stocks in the stock market, around 2000. In order to know roughly whether the whole market is going up or down, we can find some companies that can represent the national economic situation and major industries from so many stocks and calculate an index according to a certain weighting algorithm. Equivalent to the thermometer of the stock market.
Similar to a thermometer, it first reflects the situation of the stock market, that is, the decline of these index stocks leads to the decline of the index. It's like the arrival of a cold current causing the temperature to drop, but, conversely, when you see the index change, it will also affect your behavior. It's like seeing the thermometer change before adding or subtracting clothes.
What does exponential average mean?

What does the basic index in the stock mean?
Take the Shanghai and Shenzhen 300 stock indexes as an example, the value of each point is equivalent to RMB 300 yuan. If you buy a hand now, assuming that the current position is 2 100. 12, then its value is: 300 * 2100.12 = 630036 yuan. Among them, the index value is calculated from the weighted average of 300 stocks selected by Shenzhen and Shanghai stock markets, which can only represent the overall performance of China stock market. If the Shanghai and Shenzhen 300 stock indexes keep rising, it shows that the China stock market is performing well, the economic situation in China is improving, while the China stock market is weakening and the economic situation is deteriorating. However, the current downward trend of China stock market is not entirely due to the economic deterioration, but to a great extent due to the problems brought about by the share reform, and the continuous issuance of junk new shares and the unfreezing of a large number of restricted shares in China stock market.

What does the name of the index in the stock mean?
Stock index is an index that describes the changes of the overall price level of the stock market. It is to select a group of representative stocks, weight and average their prices, and get them through certain calculation. The specific stock selection and calculation methods of various indexes are different.
Definition:
Stock price index is an index used to reflect the overall level and changes of various stock market prices in the whole stock market. Stock index for short. It is compiled by stock exchanges or financial services institutions to represent the reference index of stock market changes. Due to the volatility of stock prices, investors are bound to face market price risks.
It is easy for investors to know the price changes of a specific stock, but it is neither easy nor annoying to know the price changes of various stocks one by one. In order to adapt to this situation and need, some financial service institutions use their business knowledge and familiarity with the market to compile stock price indexes, such as State Street Investment, and publish them publicly as indicators of market price changes. Based on this, investors can test the effect of their investment and predict the trend of the stock market. At the same time, the press and company bosses also use this as a reference index to observe and predict the economic development situation.

There are three factors to be considered in calculating the stock index: first, sampling, that is, extracting a few representative constituent stocks from many stocks; The second is weighted, weighted average by unit price or total value, or unweighted average; The third is a calculation program, which calculates arithmetic average, geometric average, or considers price and total value.
Because there are many kinds of listed stocks, it is difficult and complicated to calculate the average price or index of all listed stocks. Therefore, people often choose several representative sample stocks from listed stocks and calculate the average price or index of these sample stocks. Used to indicate the general trend and fluctuation range of stock prices in the whole market.
When calculating the average or index of stock prices, the following four points are usually considered:
(1) sample stocks must be typical and common. Therefore, when selecting samples, factors such as industry distribution, market influence, stock grade and appropriate quantity should be considered comprehensively.
(2) The calculation method should have high adaptability, and can make corresponding adjustments or corrections to the rapidly changing stock market, so that the stock index or average value has good sensitivity.
(3) There should be scientific calculation basis and means. The calculation basis must be unified, generally based on the closing price, but with the increase of calculation frequency, some are calculated at the hourly price or even shorter time.
(4) The base period should be well balanced and representative.

What is the meaning of "index" in index funds?
Is to track the index and make it the same as the index.
In the eyes of many investors, index funds operate well, just buy the corresponding stocks according to the index structure and hold them all the time. In fact, operating an index fund will also face great challenges-how to quickly switch between cash and stocks in the face of huge redemption or subscription, how to quickly change positions when adjusting index stocks, and when the index fund reaches a certain scale, it is not easy to complete the operation. In fact, it is almost "impossible" for index funds to completely copy index returns. Even the flagship S &；; P500 index fund, its 10 compound return is only 6.49%, slightly lower than S&; 6.57% of the P500 index itself. Of course, the cumulative error of 10 is only so small, which is actually quite good.
