6. Securities investment fund is a kind of collective securities investment mode of benefit sharing and risk sharing. That is to say, through issuing fund units, investors' funds are concentrated, which are entrusted by the fund trustee, managed and used by the fund manager, and invested in stocks, bonds and other financial instruments. In our country. The fund trustee must be a qualified commercial bank, and the fund manager must be a professional fund management company. Fund investors enjoy the income of securities investment fund, but also bear the risk of loss< The characteristics of securities investment funds are as follows:

(1) securities investment funds are operated by experts, managed and invested in the securities market. China's interim measures for the administration of securities investment funds stipulates that the proportion of securities investment funds invested in stocks and bonds shall not be less than 80% of the total assets of the funds. Fund assets are managed by professional fund management companies. Fund management companies are equipped with a large number of investment experts, who not only master a wide range of investment analysis and portfolio theory knowledge, but also accumulate considerable experience in the field of investment< (2) securities investment fund is an indirect way of securities investment. Investors invest in the securities market indirectly by purchasing funds. Compared with buying stocks directly. Investors have no direct relationship with listed companies, do not participate in the company's decision-making and management, only enjoy the right to distribute the company's profits. If investors directly invest in stocks and bonds, they will become the owners of stocks and bonds and bear the investment risks directly. If an investor purchases a securities investment fund, it is the fund manager who manages and operates the fund assets and concts securities trading. Therefore, for investors, securities investment fund is an indirect way of securities investment< (3) securities investment fund has the advantages of small investment and low cost. In China, the face value of each fund unit is 1 yuan. The minimum investment amount of securities investment fund is generally low. Investors can buy more or less fund units according to their own financial resources, thus solving the problem of small and medium investors; Not much money, difficult to enter the market & quot; It's a matter of time

the cost of the fund is usually low. According to the general practice in the international market, the management fee charged by the fund management company to the fund for providing fund management services is generally 1% - 2.5% of the net asset value of the fund, while the fee for investors to purchase the fund is usually 0.25% of the total subscription amount, which is lower than the fee for purchasing shares. In addition, because funds concentrate a large amount of funds for securities trading, they usually get preferential treatment from securities dealers in terms of handling charges. In order to support the development of the fund instry, many countries and regions also give preferential treatment to the tax of funds, so that the tax borne by investors investing in securities through funds is not higher than that borne by direct investment in securities< (4) securities investment funds have the advantages of portfolio investment and risk diversification. According to the experience of investment experts, we should at least diversify the risks in investment. There is a proverb in Investment Science: & quot; Don't put your eggs in the same basket However, small and medium investors are usually unable to do so. If investors invest all their money in the stock of a company, once the company goes bankrupt, they may lose everything. The securities investment fund collects small amount of funds from many small and medium-sized investors. The formation of strong financial strength can disperse investors' funds into various stocks at the same time, so that the losses caused by the falling price of some stocks can be made up by the profits of the rising price of other stocks, thus dispersing the investment risks. For example, the "Interim Measures for the administration of securities investment funds" recently promulgated by China stipulates that the shares of a listed company held by a fund shall not exceed 10% of the net asset value of the fund. In other words, if a fund invests 80% of its net asset value in stocks, it should buy at least eight companies< (5) securities investment funds have strong liquidity. The trading procere of the fund is very simple. For open-end funds

investors can either purchase or redeem funds directly from fund management companies, or through sales agencies such as securities companies, or entrust investment consultants to purchase funds on their behalf. Most of the foreign funds are open-end funds, which are quoted publicly every day, and investors can buy or redeem them at any time
securities investment funds can be divided into different types according to different standards

(3) according to the difference of investment risk and return, investment funds can be divided into growth investment funds, income investment funds and balanced investment funds. Growth investment fund refers to the investment fund whose investment purpose is to pursue the long-term growth of capital; Income fund refers to the investment fund which aims to bring investors a high level of current income; Balanced investment fund is an investment fund which aims to pay the current income and pursue the long-term growth of capital< (4) investment funds can be divided into stock fund, bond fund, money market fund, futures fund, option fund, index fund and warrant fund according to different investment objects. The stock fund refers to the investment fund which takes the stock as the investment object; Bond fund refers to the investment fund with bonds as the investment object; Money market fund refers to the investment fund that takes treasury bonds, large amount bank transferable certificates of deposit, commercial bills, corporate bonds and other short-term securities in the money market as investment objects; Futures fund refers to the investment fund with all kinds of futures as the main investment object; Option fund refers to the investment fund whose investment object is the stock option that can distribute dividend; Index fund refers to the investment fund whose investment object is the price index of a certain securities market; Warrant fund refers to the investment fund with warrants as the investment object

stock price index
stock price index. It is a kind of indicator for reference, which is compiled by stock exchange or financial service institution to indicate the change of stock market. Because of the volatility of stock prices, investors are bound to face market price risk. It's easy for investors to understand the price changes of a specific stock, but it's not easy and tedious to understand the price changes of various stocks one by one. In order to adapt to this situation and need, some financial service institutions make use of their own business knowledge and the advantage of being familiar with the market to compile stock price indexes, which are published 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, company owners and even political leaders also take this as a reference index to observe and predict the social, political and economic development situation. This kind of stock index is the average price that shows the change of stock market. The compilation of stock index is usually based on a certain month of a certain year. The stock price of this base period is taken as 100. The percentage of increase and decrease is calculated by comparing the stock price of each subsequent period with that of the base period, which is the stock index of this period. According to the rise and fall of the index, investors can judge the trend of the stock price. And in order to reflect the trend of the stock market to investors in real time, almost all stock markets publish the stock price index at the same time when the stock price changes. Three factors should be considered when calculating stock index: one is sampling, that is, selecting a few representative constituent stocks from a large number of stocks; The second is weighted, weighted average according to unit price or total value, or no weighted average; The third is the calculation program, which calculates arithmetic mean, geometric mean, or both price and total value. Because there are many kinds of listed stocks, it is difficult and complex to calculate the average price or index of all the listed stocks. Therefore, people often choose some representative sample stocks from the listed stocks and calculate the average price or index of these sample stocks. It is used to show the general trend and fluctuation range of the stock price of the whole market. When calculating the average stock price or index, the following four points are often considered: (1) the sample stock must be typical and common. Therefore, the selection of sample should consider its instry distribution, market influence, stock grade, appropriate number and other factors 2) The calculation method should be highly adaptable and can adjust or revise the changing stock market, so that the stock index or average has a good sensitivity 3) There should be scientific basis and means of calculation. The calculation basis must be unified. Generally, the closing price is used as the calculation basis. However, with the increase of calculation frequency, some are calculated at hourly price or even shorter time price 4) The base period should be well balanced and representative. When calculating the stock index, the stock index and the average stock price are usually calculated separately. By definition, the stock index is the average stock price. However, in terms of their actual effects on the stock market, the average stock price is the general level reflecting the price changes of various stocks, which is usually expressed as the arithmetic average. By comparing the average stock price in different periods, people can know the change level of various stock prices. The stock index is a relative index reflecting the changes of stock prices in different periods, that is, the percentage of the average stock price in the first period as the benchmark of the average stock price in another period. Through the stock index

7. 1. When you see that the stock in your hand is going up, and you judge that it will go up a little bit, don't sell it for the time being. When it's temporarily consolidated, or you think it won't rise again, it's not too late to declare to sell
2. The time of online stock speculation should be synchronized with the trading time of the exchange
3, not necessarily. You have to have one that matches your declaration. For example, if you declare a sale of 10 yuan, if you declare a purchase of 10 yuan or more, the transaction is possible. In addition, if you declare 10 yuan to sell, and someone in front of you has already declared 10 yuan to sell, and there are 10 yuan to buy, but the volume is not much. Generally speaking, it's not your turn to make a deal with it, and it's also impossible to make a deal. And when you declare, before you make a deal, when the trading time is up and the stock market is closed, there will be no deal.

8. Devaluation will not happen. On the contrary, it will appreciate. To say the least, the epidemic situation in the United States will be more serious. Unless the United States does not exist, other currencies will not be able to replace the US dollar in the short term. Now that the exchange rate has broken seven, the US dollar will increase by 10 cents, and the US dollar will increase by $1000

9. Characteristics of stock funds:
① compared with other funds, the investment objects of stock funds are diverse, and the investment purposes are also diverse< (2) compared with investors' direct investment in the stock market, stock funds have the risk of diversification. The cost is low. For general investors, personal capital is limited after all, and it is difficult to rece the investment risk by diversifying the types of investment. But if we invest in the stock fund, investors can not only share the income of all kinds of stocks, but also spread the risk on all kinds of stocks by investing in the stock fund, which greatly reces the investment risk. In addition, when investors invest in stock funds, they can also enjoy the comparative advantage of the fund's large investment in cost, rece the investment cost, improve the investment efficiency, and obtain the benefits of scale efficiency

③ from the perspective of asset liquidity, stock funds have the characteristics of strong liquidity and high liquidity. The investment object of the stock fund is the stock with excellent liquidity. The fund has high asset quality and is easy to realize

4. For investors, stock funds have stable operation and considerable returns. Generally speaking, the risk of stock fund is lower than that of stock investment. So the income is stable. Not only that, after the closed-end stock fund is listed, investors can also obtain the bid ask spread by trading in the exchange. After the expiration of the fund, investors have the right to distribute the remaining assets< (5) stock funds also have the function and characteristics of financing in the international market. As far as the stock market is concerned, the degree of internationalization of its capital is lower than that of foreign exchange market and bond market. Generally speaking, the stocks of various countries are basically traded in their own markets, and the stock investors can only invest in the stocks listed in their own countries or the stocks of a few foreign companies listed locally. In foreign countries, stock funds break through this restriction, investors can buy stock funds and invest in the stock market of other countries or regions, which has a positive role in promoting the internationalization of the stock market. Judging from the current situation of overseas stock markets, a large part of the investment objects of stock funds are foreign company stocks

the number of novel coronavirus pneumonia confirmed in the United States exceeds 120 thousand, and the number of new confirmed cases in the United States today is more than 20 thousand. p>

the U.S. epidemic has a direct impact on the U.S. economy and the U.S. stock market. How will the U.S. stock market go

according to the current situation in the United States, how will the U.S. stock market go from three aspects

first aspect: American economic analysis

the stock market is a barometer of the economy, and the quality of the economy will be directly reflected in the stock market

judging from the current economic growth rate of the United States, it is inevitable that the economic growth rate of the United States will enter a recession period

as shown in the figure above, this is the recent K-line chart of the US stock market. From the technical point of view of the US stock market, it is completely a short market, and the short-term rebound rate is probably a decline relay

from a technical point of view, the US stock market closed at 21636 on Friday, which has stabilized its 5-day and 10 day moving average, and has blocked its 20 day moving average. After the blocking, there is a high probability that the US stock market will continue to fall again next week

stock speculation should follow the trend, just follow the trend, not go against the trend. Therefore, the U.S. stock market has a downward trend, the trend is formed, and it is inevitable to continue to fall

based on the analysis of the above three aspects of the United States and the US stock market, it is concluded that the US stock market is bearish in the short term, so I personally think the short-term trend of the US stock market will continue to fall

the current 18213 point of US stocks is not the lowest point. It is likely that there will be a new low point in the future. I expect that there is a high probability that US stocks will stop falling near 15000 points
