What is the meaning of long and short in digital currency contra
short selling mechanism, also known as short selling. Suppose you have 100 A shares (this is called spot stock) with a market price of 10 yuan. Now I borrow these 100 shares from you and sell them at the price of 10 yuan. Then when the share price falls to 9 yuan, I buy back 100 A shares and give them back to you. I earn a price difference of 100 yuan (100 * 10-100 * 9). Your stock is still 100 shares, no change, but I earned 100 yuan, which is my short selling stock
this is the short mechanism. In practice, I need to deposit a deposit in advance as a guarantee. With the rise of the share price, I have to add more deposit, because when the share price rises to 11 yuan, I will spend 1100 yuan to buy back 100 shares and return them to you (I lose 100 yuan). The higher the share price rises, the greater my loss will be. But you will never lose money, because as long as I return 100 shares to you, of course, I will certainly pay you some fees, which is equivalent to the interest on the loan
in this case, I am an ordinary investor, and you are a securities company or futures company. Of course, you can also use this principle to make money by renting stocks or short selling stocks from private investors. In this way, you can realize short selling of spot stocks. Although it is illegal, it is completely reasonable and cannot be restricted by law. In fact, this method is used by institutional investors and QFII
many people can't understand short selling because they can't understand why I can sell without any stocks? In fact, stocks are borrowed. If the stock is a physical object, it will be easy for us to understand it. But in the financial market, many people can't understand it because everything is digital.
short selling to build a position refers to selling a position, which can also be called short interest, selling a certain currency and being bearish. Some people call it long or short. Short selling mechanism is to borrow other people's shares to sell in advance when the market is going to fall at a high level, and then buy them back at a low level and return them to the borrower to close the position to make a profit. It is the reverse operation of the current buying stock to make a profit by rising. Because it makes a profit by falling, it will attract a large number of funds to short in the bear market.
for example, when we are in the cabbage business, we think the price of cabbage will rise. We buy a lot of cabbage when it costs 30 cents a kilogram, and then sell it all when it costs 50 cents a kilogram. This is to be long
short selling means that the price will go down. We can understand it like this: when the exchange rate is very high, we think it may fall in the future. At this time, we borrow the currency in front of the exchange, and sell it first when the exchange rate is high. When the exchange rate falls, we buy the money we sell back to the exchange. In this way, the transaction behavior of getting the price difference by selling high and buying low is called empty, which is a kind of transaction of selling first and then buying
for example, if you think that the price of Chinese cabbage will fall, you will borrow a lot of Chinese cabbage from some Chinese cabbage merchants when the price of Chinese cabbage falls to 30 cents a Jin, and then buy back the same amount of Chinese cabbage in the market and return it to the Chinese cabbage merchants, and you will earn 20 cents a jin of Chinese cabbage. That's short.
