gold jewelry at wholesale prices What does the market profit and loss in the stock mean

fine jewelry wholesale suppliers The history of futures: The English of the futures is Futures, which is evolved from the term "future". The meaning is that the two parties do not have to pay for real goods at the beginning of the trading. Really, the Chinese call it "futures".

The initial futures transaction was developed from the spot in the spot. The initial spot forward transaction was an oral promise of the two parties to pay a certain number of goods at a certain time. Oral promise is gradually replaced by the contract. This kind of contract is increasingly complicated and needs to be guaranteed by intermediate people in order to supervise the delivery and payment of the buyers and sellers on schedule. Therefore, the world's first commodity forward contract exchanges opened in London in 1570, the Royal Exchange. In order to adapt to the continuous development of the commodity economy, in 1985, the Chicago Grain Exchange launched a standardized agreement called "futures contract" to replace the long -term contract that was originally used. Using this standardized contract, the contract is allowed to be transferred to buy and sell, and gradually improves the margin system. Therefore, a futures market that specializes in the standardized contract has formed. Futures have become an investment and financial tool for investors.

The basic concept of futures: Futures are standardized contracts, a uniform, long -term "cargo" contract. Buying and selling futures contracts are actually promising to buy or sell a certain amount of "cargo" ("cargo" can be physical products such as soybean, copper and other financial products in the future, or financial products such as stock indexes and foreign exchange).

The main features of futures contracts are:
a. The terms, quantities, quality, grades, delivery time, delivery location of futures contracts are all set, which are standardized. The only variable is the price. The standard for futures contracts is usually designed by the futures exchange and is listed and approved by the state regulatory agency.
b. Futures contract was sold under the organization of the futures exchange. It has legal effect, and the price is generated in the exchange of the exchange. Computer transaction.
c. The performance of futures contracts is guaranteed by the exchange and does not allow private transactions.
d. Futures contracts can perform or lift the contract obligations by settle in stock or hedge transactions.

The components of futures contracts include:
a. Transaction variety
b. The number of transactions and units
c. The minimum change price, the quotation must be the total multiple of the minimum change price.
D. The maximum fluctuation restriction of the daily price, that is, the daily limit. When the market price rose to the maximum increase, we called the "daily limit board", otherwise, the "daily limit board".
e. Contract month
f. Trading time
g. Last trading day: Last trading day refers to the last trading day of a certain futures contract in the contract of the contract;
h. Delivery time: Refers to the time for the contract to perform physical delivery;
i. Delivery standards and grades
j. Delivery location
k. Margin
L. Trading fee
r The role of N futures contracts is:
1 is to attract the hediders to use the futures market to use the futures market to buy and sell contracts, lock the cost, and avoid losses due to the risk of fluctuations in the product price of the spot market.
It is to attract speculators to conduct venture capital transactions and increase market liquidity.

The characteristics of futures transactions
1. The two -way nature of futures transactions: The biggest difference between futures transactions and the stock market is that futures can be traded in two -way, and futures can be sold short or short. When the price rises, you can buy low and sell high, and when the price falls, it can be sold high and low. You can make more money, and you can make money, so there is no bear market for futures.

2. The cost of futures transactions is low: the only fee for the tax and fees of futures trading countries does not levy stamp duty, and the only fee is the transaction fee. The current procedures of the three domestic exchanges are about two or three in ten thousand, and the additional expenses of the brokerage company, the unilateral handling fee is not one thousandth of the transaction volume.

3, the leverage of futures transactions:
The principle of leverage is the charm of futures investment. There is no need to pay all the funds in the futures market. At present, domestic futures transactions only need to pay 5%of margin to obtain the right to get future transactions.
The original quotation was amplified by more than ten times due to the use of margin. We assume that the price of copper prices in a day (the daily limit in the futures is only 3%of the previous trading day). The operation is right. Our fund profit margin is 60%(3%÷ 5%). Note.

4, "T 0" trading opportunities double: The futures are "T 0" transactions, so that your capital application is to the extreme. After you grasp the trend, you can trade at any time and close the position at any time.

5, the futures are zero -sum market but greater than the negative market: the futures are zero -sum market, and the futures market itself does not create profits. During a certain period of time, the total amount of funds in the futures market is unchanged without considering the inlet and withdrawal of funds, and the profit of market participants comes from the loss of another trader.
The on the bear market in the stock market, the market price has shrunk sharply, coupled with the meager dividends, the state and enterprises absorb funds, and there is no shorting mechanism for shortness. The total amount of funds in the stock market will increase negative growth for a period of time, and the total profit will be less than the loss.

The national policy, economic development needs, and the characteristics of the futures determine that the futures have a huge room for development.

Futures and stocks: Different investment compensation: Futures transactions can amplify the income due to the leverage of the bond, four or two pounds. Futures only need to pay less than 10%of the total value of the contract; the stock must be 100%invested, and the amount of interest is required to pay; It can be done more and can be short;

The speculation method of futures is very similar to the stock market, but it is very obvious.
. Big fighting: Stocks are full transactions, that is, how much money can only buy how much stocks, and futures are margin systems, that is, only 5%to 10%of the transaction turnover can be performed. %Of transactions. For example, investors have 10,000 yuan, buying 10 yuan of stocks can buy 1,000 shares, and investment futures can sell 100,000 yuan of commodity futures contracts. This is small fighting.

. Two -way transactions: Stocks are one -way transactions. They can only buy stocks before they can be sold; and futures can be bought or sold first. This is two -way transactions.

. Time constraints: stock transactions have no time limit. If the quilt can be closed for a long time, and the futures must be delivered at the end, otherwise the exchange will be forcibly liquidated or in physical delivery.

. The reality of profit and loss: There are two parts of the return on investment. One is the market difference, and the other is dividend dividends. The profit and loss of futures investment is the actual profit and loss in market transactions.

. Great risk: Futures due to the implementation of the deposit system, additional margin system, and forcibly liquidation due to the expiration, so that it has the characteristics of high remuneration and high risk. In a sense, in a sense , Futures can make you get rich overnight, or you may make you poverty instantly, investors should invest carefully.

This kind of spot can be a certain product, such as copper or crude oil, or a certain financial instrument, such as foreign exchange, bonds, or a certain financial Indicators, such as three -month peer borrowing interest rate or stock index.

Settlement.) Of course, traders of futures contracts can also choose to carry out the obligation of reverse trading before the contract expires.

(4) The generation of futures transactions: The futures market in the modern sense was born in the United States. In 1848, 82 merchants initiated the Organization of Chicago Futures Exchange (CBOT) to improve transportation and storage conditions Provide information for members; in 1851, Chicago Futures Exchange introduced a long -term contract; the first standardized contract was launched in 1865, and the deposit system was implemented (not more than 10%of the contract value), which is a historic institutional innovation; 1882 1882 The annual exchanges are allowed to avoid performance responsibilities by hedging, increasing the liquidity of futures transactions.

The background of China's futures market is the reform of the grain circulation system. As the state cancels the unified purchase of agricultural products, and the price of most agricultural products has been released, the market's regulation of agricultural products production, circulation and consumption has become increasingly large, the ups and downs of agricultural products and the unfinished and distorted phenomenon of spot prices, agricultural production of agricultural production Suddenly and down and the lack of value preservation mechanisms in grain companies have attracted the attention of leadership and scholars. Whether it can establish a mechanism can not only provide price signals to guide future production and operation activities the key of. In February 1988, the leaders of the State Council instructed the relevant departments to study the foreign futures market system and solve the problem of fluctuations in the price of domestic agricultural products. In March 1988, the "Government Work Report" of the Seventh National People's Congress of the Seventh National People's Congress proposed that actively developing various types of wholesale trade markets, Explore futures transactions. The prelude to the research and construction of the Chinese futures market.

In October 12, 1990 Zhengzhou Grain Wholesale Market was established by the State Council, based on spot transactions, introduced the futures transaction mechanism, and took the first step in the development of the Chinese futures market;
n n n n n n n n n n n R N June 10, 1991 was established on the Shenzhen Nonferrous Metal Exchange;

In May 28, 1991, Shanghai Metal Commodity Exchange opened;

(5) Terms related to futures transactions: Open positions, positions and liquidation: buying and selling behaviors in futures transactions, as long as it is built, is called open positions. The position held in the hands of traders is called holding. The liquidation refers to the trading behavior of the trader, and the way of knotting is to make the opposite hedge trading for the direction of the position.

Due to the different meaning of opening and liquidation, traders must indicate whether to open a position or close position when buying and selling futures contracts.

example: A certain investor bought the March 30th 300th Index Futures (Zhang) on ​​December 30, and the transaction price was 1450 points. Hold the position. By January 10 next year, the investor saw the futures price rose to 1500 points, so he sold 5 -handed stock index futures at this price at this price. After the transaction, the investor actually held 5 hands and multiple orders left. If the investor was reported to the Times of the day to sell 5 -handed stock index futures in the March. After the transaction, the investor's actual position should be 15 hands, 10 hands, and 5 -handed positions.

This: refers to the negative number of investor accounts. It shows that investors not only lose all the margin, but also owe futures brokerage companies' debt. Due to the day -by -day liquidation system and forced liquidation system of futures transactions, positions will not happen under normal circumstances. However, in some special circumstances, if the market is short, the accounts that hold a heavy position and the opposite direction may occur.

Is when the position is bursting, investors must make up for the deficit in time, otherwise they will face legal pursuit. In order to avoid this situation, special control needs to be controlled, and it is not as good as stock transactions. And to track the market in time, you cannot buy it like stock transactions.

Me long and short: Futures trading implements a two -way trading mechanism, which are both buyers and sellers. In futures transactions, the buyer is called bulls, and the seller is called short. Although the stock market transaction also refers to the buyer as a bullish, the seller is short. However, the seller in the stock transaction must be the person holding the stock, and those without stocks cannot sell it.

The settlement price: refers to the average price of the transaction price on the day of a certain futures contract. If there is no transaction on the day, the settlement price of the above trading day is the settlement price of the day. The settlement price is the basis for the settlement of the profit and loss of the unsuitled contract on the day and the formulation of the limit of the limit of the next trading day.

The volume: refers to the bilateral number of all transaction contracts during the transaction during the day of a certain futures contract.

This position: refers to the bilateral number of unlatic dwells held by futures traders.

The total positioning: the total number of "unbound contracts" on the market's futures contract on the market. In the market information released on the exchange, there is a "total position" column.

The changes in total positioning reflects investors' interest in the contract of the contract. It is an important indicator for investors to participate in the contract. If the total number of warehouses continues to grow, it indicates that both parties to the transaction are opening the position, and investors' interest in the contract is growing, and off -site funds are constantly pouring into the contract. On the contrary They are all out of position, and traders' interest in the contract is ebb. Another situation is that when the transaction volume increases, the total amount of positions has not changed much, which indicates that the market is mainly based on renewal transactions.

The change of hand -changing transactions: There are "multi -heading" and "short -to -hand" in the change of hand -changing transactions. It is called "multi -heading hands"; "short -term switching" means that the original traders were buying a liquidation, but the new short was sold.
The transaction instructions: There are three instructions for stock index futures transactions: market price instructions, price limit instructions, and cancellation instructions. The transaction instructions are valid on the day. Before the instruction is transmitted, customers can file a change or cancellation.

It, market price instructions: refers to the instructions that do not limit the purchase and sell for the price of the market as the best price of the market.

The instructions: instructions that must be transmitted at a limited or better price when performing execution. It is characterized by the transaction, which must be a customer's expectation or better price.

It, canceling instructions: refers to the instruction that the customer cancels a previous instruction. If the previous instruction has been sold before the cancellation instruction is effective, it is called the cancellation, and the customer must accept the transaction result. If part of the transaction, the remaining part can be revoked by the remaining part.

The set of period preservation: Buying (selling) is equivalent to the number of goods operated in the spot market, and the time limit is similar, but the corresponding futures contract with the opposite direction of the transaction, so as to sell it at a certain time in the future by selling the sale at some time in the future. (Buy) the same futures contract to replace the actual price risk brought by this product or financial instrument due to market price changes.

The margin: The deposit is the exchange of money

for investors to ensure the guarantee of the contract. A amount of funds on its account. According to different properties, the deposit is divided into three types: transaction margin, settlement margin and additional security deposit. Trading margin refers to the funds that investors ensure their performance in the exchange of special settlement accounts, and they are margin occupied by the contract; the settlement margin is the remaining part of the investor in the exchanges' dedicated settlement account and removed the remaining part of the trading deposit that has been occupied by the exchange. Essence Adding margin refers to if the equity of the investor account was smaller than the positioning deposit on the day, it means that the balance of funds is negative, and it also means that the deposit is insufficient. According to regulations, the futures brokerage company will notify the account owner to make up the deposit before opening the market on the next trading day. This is called additional deposit.

Forced liquidation: If the account owner did not make up the deposit before opening the market on the next trading day, according to the regulations, the futures brokerage company can implement some or all of the positions of the account of the account. Until the retained margin meets the requirements.

Displicable restrictions: that is, the transaction site limit. The maximum limit of the exchanges to the number of certain futures contracts stipulated in investors is to manage market risks from the perspective of market share distribution.

The bidding method: computer matching transactions. Computer matching transactions are an automated trading method designed based on the principle of public screaming. It has the advantages of accurate, continuous, fast speed, and large capacity.

The early futures transaction, because there is no computer, the public price method is adopted during the transaction. There are usually two forms of publicly screaming methods: First, a continuous auction (dynamic disk), refers to the face -to -face price of traders in the exchange trading pool, expressing their requirements for their own buying or selling contracts. This bidding method is the mainstream of futures transactions, and the European and American futures market adopts this method. The advantage of this method is that the atmosphere in the field is active, but the defect is that the size of the personnel is limited by the venue. Many traders were crowded in the trading pool, and their voice was full of voices, so that traders had to use gestures to help pass trading information. Another shortcoming is that on -site traders have more information and time advantages than traders outside the field. Raising hats often become a patent for traders on the court.

The public shouting another form is a one -price system in Japan. One section and one price system divides each trading day into several sections, and one contract in each trading has only one price. Each trading is called by the host first, and the trader on the venue reports to the number of buying and selling according to its price. When the number of transactions between the buyers and sellers is equal at a price. After the popularization of computer technology, exchanges around the world have adopted computers instead of the original open -minded approach.

2, the basic characteristics of futures transactions: The object of futures transactions is standardized contracts. Futures contract refers to the standardized, legal constraints that are traded in the exchange formulated by the futures exchange and stipulated in a certain time and place in a certain time and place in the future.

Chopida transactions are a standardized transaction. Standardization refers to all the terms of futures contracts in the process of futures transactions. All terms of futures contracts are pre -stipulated.

The long -to -short two -way trading system.
The futures transaction implementation T 0 transaction system.
Futures transactions are a differential margin transaction.
The futures transactions are carried out day by day, and the daily liability settlement system is implemented. Refers to the daily

In the transaction, the exchanges settle the profit and loss, transaction margin, handling fees, taxes and other fees of all contracts on the day of the settlement price. Increase or reduce members' settlement reserve. The futures brokerage company settled the customer based on the settlement results of the futures exchange and notified the customer in time to notify the customer in time.

This marketing system and market -by -time market, daily liability settlement system is a unique system for controlling market risks.

3, the difference and difference between futures transaction and stock transactions:

connection: all capital investment, belonging to the financial market category, so it is investing in

The use of ideas, methods, and technical indicators has the same aspects. It is easier to enter the futures market with stocks and foreign exchange investment, and it is also easier to master futures investment skills.

:

(1) Different investment objects: stocks belong to spot transactions, have clear investment targets, futures investment belongs to futures transactions. It is a future transaction. The object is the contract. If it is delivered in a certain period of the future, then the current transaction is a sale of future commodities. If it is not delivered, then the current transaction is only an expectation, a expectation of future price trends.

(2) Different capital use efficiency: stock transactions implement a full cash transaction, and the amount of investor funds determines the amount of transaction volume. In the face of emergencies, the scheduling of funds will become restricted investment. The main problem of transaction. Futures transactions implement a margin system. The general margin ratio is about 5%-8%, and the funds are obvious. Under the premise of controlling risks, investors in the face of emergencies can have enough time and funds to operate.

(3) Different transaction mechanisms: Stock transactions are a current (real) cargo transaction. At present, the stock market does not have shorting mechanisms. Futures transactions are largely a virtual transaction with two short and short transaction mechanisms, and the T 0 transaction settlement system is implemented.

(4) Different risk control methods: Although stocks and futures transactions have stipulated the risk control system, such as the rising and daily limit board system, but because of the relationship of the system, the current system venture capital of the stock market is It is difficult for those who are difficult to avoid and lack the short -term mechanism. Investors to avoid market risks can only sell stocks. Because futures transactions have two forms of long and short forms, the means of controlling market risks, in addition to common general forms, also You can use the hedging function to avoid market risks. The restriction system and compulsory liquidation system of futures transactions are also the main risk control system that is different from stock transactions.

(5) Different analysis methods: The technical analysis method is common; but from the perspective of fundamental analysis methods, because the target of futures investment is mainly commodity futures, the characteristics of the price trend of the product itself are very important. The characteristics of commodity prices are mainly reflected in the supply and demand of goods, and the basic factors affecting the price of commodity prices are relatively clear and fixed. The fundamentals of stock fundamentals are mainly the operating status of listed companies.

(6) The disclosure and transparency of the information: The futures market is more transparent than the information of the stock market, and the information communication channel is more clear.

(7) It is important to emphasize that the social and economic functions of futures transactions and stock transactions are also inconsistent. Stocks provide re -allocation functions for fundraising and social resources, and futures transactions provide avoiding risks and price discovery functions.
4. Futures of futures transactions:

In found price: Because futures transactions are publicly carried out a contract with long -term delivery r
A large number of market supply and demand information is concentrated, different people, different locations, different understandings of various information, and different views on long -term prices through public bidding forms. The futures transaction process is actually a comprehensive reflecting the expectations of the supply and demand relationship and price trend of the supply and demand relationship between the supply and demand parties in the future. This price information has the characteristics of continuity, openness, and expected, which is conducive to increasing market transparency and improving the efficiency of resource allocation.

The example: Hunan Changde City Grain and Oil Corporation uses the Shanghai Grain and Oil Commodity Exchange to guide farmers to create revenue. Prior to 1994, the enthusiasm of farmers planting food in the Changde area declined, and the land was serious. In early 1994, the Changde Municipal Government controlled the expected price of rice in September and October from the Shanghai Grain and Oil Commodity Exchange (the local spot price was below 2,000 yuan/ton, and the price of 10 japonica futures contracts for grain exchange was 2400 yuan/ton. Left and right) guide farmers to expand the planting area of ​​72,000 acres, and the increase in rice production by 250,000 tons has received good returns. In October of that year, the spot price rose to more than 2350 yuan/ton.

The avoidance risk: The generation of futures transactions provides a place and means to avoid price risks for the spot market. The main principle is to use the two markets of the spot period for the two markets for hedging transactions. In the actual production and operation process, in order to avoid the ever -changing of commodity prices leading to rising costs or decline in profits, it can use futures transactions to preserve the dating, that is, buying or selling in the futures market is equal to the number of in the spot market but the opposite of the transaction direction is the opposite direction. Futures contracts make the profit and loss of futures market transactions. Lock the production cost or product sales price of the enterprise, keep the established profits and avoid price risks.

The set of period preservation: When buying or selling a certain amount of spot products in the spot market, it sells or buys the same, the same number of futures, but the opposite direction in the futures market (Futures contract), to make up for the losses of another market with the profit of one market, and achieve the goal of avoiding price risks.

This futures transactions can be preserved because the spot price of a specific commodity is also affected and restricted by the common economic factors. The existence of the mechanism, in the nearby futures contract delivery period, the future spot price has convergence.

The delivery: The knot of futures transactions (ie, the liquidation) generally has two ways, one is the hedging liquidation; the other is physical delivery. The physical delivery is to perform the responsibility of futures transactions with physical settlement. Therefore, futures delivery refers to the trading and sellers of futures transactions when the contract expires, and the expires of the expiration of their respective expirations shall be fulfilled to perform physical delivery in accordance with the provisions of the exchange, and the futures transactions will be associated. The proportion of physical delivery in the total number of futures contracts is small. However, it is the existence of the physical delivery mechanism that makes the futures price change and related spot price changes synchronized, and gradually approach as the contract is approaching the date. In terms of nature, the nature of physical delivery is a type of spot transaction, but the physical delivery that occurs in futures transactions is the continuation of futures transactions. It is at the delivery point of the futures market and the spot market. Bond, so the physical delivery in futures transactions is the basis for the existence of the futures market and the fundamental prerequisite for the two major economic functions of the futures market.

The two major features of futures transactions allow the two trading models of the futures market to have the stage and foundation used. The price discovery function requires many speculators to participate. A large number of market information and abundant liquidity The existence of the hedging transaction method provides tools and means for avoiding risks. At the same time, it is also an investment tool. Due to the fluctuation of futures contract prices, traders can use arbitrage transactions to earn risk profits through the spread of contract transactions.

The role in the futures market: The macro -control of the futures market for the operation of the national economy and the operation of enterprises in the operation of the market economy have provided reference for the government's macro -control, which helps the establishment and improvement of the market economy system , Improve the allocation of resources, regulate market supply and demand, slow down price fluctuations and form a fair and open price signal, avoid market risks caused by price fluctuations, reduce circulation costs, stabilize production and sales relationships, lock production costs, stabilize enterprise operating profit, etc. effect.
5, the classification of futures transactions:

C product futures and financial futures. Commodity futures are divided into industrial products (can be subdivided into metal goods (precious metals and non -precious metal products), energy goods), energy products), agricultural products, other goods, etc. Financial futures are mainly traditional financial commodities (tools) such as stock indexes, interest rates, exchange rates, etc., and various futures transactions include options transactions.

If in addition to the price difference, there are costs such as the commission. After comprehensive calculation, you can know the profit and loss of your stock. Of course, if you do n’t sell it, the profit and loss displayed in the software is a win -win situation, and it becomes a real profit and loss after sale.

This is a indicator for assessing whether your recent stock operation is profitable.
