7. What's the meaning of short position explosion

short position explosion refers to the phenomenon that when shorting stocks or futures, the margin can not offset the loss e to the excessive fluctuation of the market, so it is forced to close the position by brokers. Shorting is to make profits through the fall of asset prices. Whether shorting stocks or futures, it needs to pay a certain margin. If the theoretical margin is 10% of the actual position value, then the actual reverse volatility that investors can bear is only 10%

in the aspect of stocks, short selling is realized by borrowing stocks through securities lending and then selling them, and then buying and returning the stocks after the stock price falls. Futures are directly short orders

in short, both stocks and futures are settled without liabilities. Therefore, when the market is unfavorable, the principal can not be held in liabilities after the loss is completed, and the position will be forced to close

first, only in two cases can a burst occur. One is to borrow other people's money to invest, which is usually an exchange, a securities firm or other institution. Second, although they did not borrow money, they invested in contracts, such as futures, because these trading modes adopted margin system, which has its own leverage effect. If you just use your own money to invest, it will not burst the position, and you will never sell it

Second, the position explosion can be understood as forced closing or even crossing. Take the stock as an example. Even if the stock price falls sharply after we buy it, as long as we do not withdraw from the market, we can not sell it, even for ten or twenty years, until the stock price rises and returns to its original value, and there will be no burst of positions. But when borrowing money to speculate in stocks, because part of the money is not yours but borrowed, when the stock price keeps falling and threatens the safety of the lender's capital, it will force you to close the position, that is to say, you have to sell your stocks. In extreme cases, even if forced to sell, will still make the borrower's money lost. The investor not only has no money left, but also has to pay more money to the lender

Third, on January 4, bitcoin plunged sharply, falling to 29000 USD at most, causing some contract makers to burst their positions. In fact, the price of bitcoin is only about 10%, but people who use ten times leverage may not be able to bear it. Let me give you a few examples to illustrate how the burst happened

suppose that the investor Xiao Wang takes a fancy to a stock and has his own capital of 100000 yuan. At the same time, he adds ten times leverage to enlarge the capital to 1 million yuan. Of the 1 million yuan, 900000 yuan was borrowed from the organization. Xiao Wang bought 10 yuan a share, a total of 10000 shares

after buying, assume that the next day's share price falls by 8%, and the share price becomes 9.2 yuan. For 1 million yuan, the loss is 80000 yuan. At this time, the market value of Xiaowang's own 100000 yuan capital is only 20000 yuan. If the share price continues to fall, not only the last 20000 yuan may not be left, but also the borrowed 900000 yuan may suffer losses

in order to ensure the safety of their own funds, the organization will ask Xiao Wang to fill the position, that is, to take some more funds to fill it. If Xiao Wang has no money or is not willing to invest free funds, there will be a risk of burst positions. Basically, the institutions will sell stocks directly without Xiao Wang's consent. Assuming that the final transaction price is 9.1 yuan per share, 100000 shares can be sold for 910000 yuan in cash, of which 900000 yuan will be returned to the institution and 10000 yuan will be returned to Xiao Wang (ignoring the borrowing cost, Xiao Wang can't even get 10000 yuan, because he has to pay the interest of borrowing to speculate in stocks). In one day, Xiao Wang lost 90000 yuan from 100000 yuan.
