The so-called position is the ratio of the partial stock fund you hold to the sum of the cash of the money fund and investment fund you hold. That is, the stock base/total investment is your position. Position refers to the ratio of the actual investment of investors to the actual investment of funds. For example, you have 6,543,800 yuan for investment funds, and now you spend 40,000 yuan to buy funds or stocks. Your position is 40%. If you buy all the funds or stocks, you will be in Man Cang. If you redeem the fund in full and sell the share, you will be short. If the current market is very dangerous and may fall at any time, then you should not go to Man Cang, because if the market falls, you may lose money selling futures, but you have no money to buy futures, so you are very passive. Usually when the market is dangerous, you should have half or less positions. In this way, in case the market plummets and you find that the futures you hold have fallen to a very low price, you can buy them, and when they go up, you can sell your original ones and earn the difference. Generally speaking, the position should be kept in a semi-warehouse state at ordinary times, that is to say, reserve forces should be left in case of accidents. Only when the market is very good can you visit Man Cang for a short time.
