viva beads jewelry wholesale What does "short spot" mean? Seeking Great God help

wholesale jewelry dozen pack The spot is relatively speaking with futures. The futures have short -term mechanisms. There is currently no shortcoming mechanism for spot. The short -term mechanism, also known as short selling. Suppose you have 100 A -shares (this is called spot), the market price is 10 yuan, I now borrow you from this 100 shares, sell it at a price of 10 yuan, and then wait for the stock price to fall to 9 yuan, I buy another 100 shares A A. The stock will be returned to you, and I earn a difference of 100 yuan (100*10-100*9). The stock in your hand is still 100 shares, and there is no change, but I earn 100 yuan. This 100 yuan is my short -selling stock. This is the shorting mechanism. In actual operation, I need to deposit a deposit in advance as a guarantee. As the stock price rises, I must add more margin, because when the stock price rises to 11 yuan, I will spend 1100 yuan to buy back 100 shares will also give you (I lose 100 yuan). The higher the stock price, the greater my loss. But you will never lose money, because as long as I give you 100 shares, of course, I will definitely pay you some fees, which is equivalent to the interest of borrowing. In this example, I am an ordinary investor, and you are a securities company or a futures company. Of course, you can also use this principle to make money by renting stocks or sell them to private stocks, so that you can achieve the short selling of stocks. Although it is illegal, it is completely reasonable and the law cannot be restrained. In fact, this method is in this way. Institutions and QFII are used. Many people can't understand the short selling because they can't understand that I don't have any stocks in their hands. Why can they sell it first? In fact, stocks are borrowed. If the stock is real, it is easy for everyone to understand, but in the financial market, many talents cannot understand because everything is a number.
