1. There are two reasons why the stock price will fall even if there is a large amount of capital inflow: This is closely related to the nature and direction of capital inflow

1

the main force is not equal to "banker". Some institutions are the main force, but they seldom do business

for example, public funds, some QFII and some securities companies are the main force to buy a stock. They are optimistic about the long-term investment value of a stock, and they will not move for one or two or even three or five years after they buy it. Of course, when the capital flows in, the stock price may rise for a short time, but not too much. After the main buying, e to the decline of trading volume, plus some retail investors and short-term hot money, they do not like the stocks with public fund positions, and sell stocks one after another, which will cause a short-term decline in the stock price

2. It depends on what to do after the main capital flows in

first of all, we should pay attention to one problem: institutions will not absorb chips when the stock price is high (that is, inject funds), but will only absorb chips when the stock price is low or volatile. Since it is the main force, it is impossible to raise funds only once, and it is often possible to raise funds two or three times or even more

because of the large amount of main funds, it needs a lot of chips. It is impossible to build the warehouse in one or two days, but it needs a long-term process. Short two or three months, long half a year or even a year

while the main force is unlikely to attract funds at a high position, ring the main force's position building period, although there is a continuous inflow of funds, in order to ensure that the main force can absorb enough chips at a low position, the main force will continuously suppress the stock price in the process of absorbing, so as to absorb chips at a lower price. In addition, even if the main fund-raising is completed, it will also take the way of washing up, washing out some weak willed follow suit retail investors. This is the fundamental reason why, seeing the inflow of major capital, the stock price has fallen instead

extended data:

capital inflow is more appropriate to say "buying up capital volume", and capital outflow is "selling down capital volume"

for example

for example, Guizhou Maotai trades four hours a day, totaling 240 minutes (random number). In these 240 minutes, the time for the stock price to fall is 100 minutes, the time for the stock price to rise is 80 minutes, and the time for the stock price not to rise or fall is 60 minutes

add up the trading volume in the falling 100 minutes, that is the capital outflow; Add up the turnover in the 80 minutes of the rise to the inflow of funds

don't throw away the 60 minutes without going up or down. Subtract the outflow and inflow of funds from each other, and the large amount represents the outflow or inflow of funds on that day.
2. It's four peaks:

the first time, in March last year, bitcoin soared from tens of dollars to 266 dollars overnight

for the second time, the United States held a bitcoin hearing on September 18 last year. Before the hearing, the Federal Reserve and other relevant people looked at bitcoin. Under the influence of the good news again, the price of bitcoin rose to 8000 yuan

the third time is ring this year's World Cup. Due to the influence of the world cup, the price of bitcoin once approached 6000

for the fourth time, bitcoin suddenly rose to 3000 yuan after six months of continuous downturn and hovering around 2400 for a long time. It is said that it is the entry of hot money.
3. It can't be simply attributed to the exchange. Sometimes there are sudden short-term fluctuations, and the exchange does participate. But the main topic is about the monthly time span, which is difficult for the exchange to control. It is more the result of the joint operation of hot money and large institutions. However, the sharp decline of the overall currency value can't be separated from the basic economic principle: the relationship between supply and demand, This is beyond anyone's control

5. Hello, the ore excavated in Zhanshen palace is in the material of the luggage
6. More than 125 people went to arahi, thorn Valley and barren land to dig iron ore
after 175, there were more secret silver caves and several refresh points beside the altar, and they could dig 245 pieces of silver together. However, at that time, it was mainly to dig secret silver, and there was little silver. Go to 275 to dig the silver of fuser, which is covered by mud in the worm hole of sirisus.
it's better to get a set of equipment with mining skills, such as 175 to dig the silver of mysteries. Your 170 + gloves enchant 5 mining shows that you can dig orange and add skill points~~~
7. Domestic trading platform only three exchanges are the most secure, the rest have problems
three major exchanges: okex, fire currency and coin security.
8. Gambling money has the risk of ruin, because it may become rich overnight, or it may have nothing overnight. This risk is too big for ordinary people to bear, so we should not gamble money.
9. Guangzhou metro line 17 is planned to be located in the core of the future Guangzhou new town in Panyu District, from west to East, from Zini station through Panyu Square Station to GAC base station. Connecting with line 4, East extension of line 3, line 8, line 18 and line 22, it is an important line to form the core rail transit network of Guangzhou new East in the future
route introction
Zini Station - Shawan West Station - Shawan East Station - Qiaonan Station - Panyu Square Station - luojiacun Station - Pangdong Station - Shiqi West Station - Dalong Station - Guanqiao Station - Tanshan Station - Mengdi Station - GAC base
[transfer station] transfer to line 3, line 18 and line 22 at Panyu Square Station, line 4 at Shiqi station, and line 8 at Mengdi station, Transfer to line 8 extension at GAC base station.
10. I can charge it here
