(1) Is the investor's deposit sufficient?
Transaction fee = 10 yuan *20=200.
Margin =3000 yuan/ton * 10 ton/lot *20 lots * 10%=60000.
Book balance at this time: 100000-60000-200=39800.
So at this time, the deposit is sufficient.
(2) When the settlement price drops to 2700 yuan/ton, how much money is left in the investor's account?
Down to 2,700 yuan/ton, earning 300 yuan per ton,
Earn in one hand: 300 yuan/ton * 10 ton/hand = 3,000 yuan/hand.
Earn money in 20 lots: 3,000 yuan/lot *20 lots = 60,000 yuan.
At this time, the remaining funds in the book = margin+remaining funds in the book +20 earned funds = 60000+39800+60000 =159800.
On a certain day in a certain month, an investor deposited 30,000 yuan into his account for futures trading. The next day, he sold 10 lots of wheat futures contracts (each lot 10 tons) at a price of 2800 yuan/ton. Assume that the wheat margin ratio of the exchange is 10%. Question: (1) If the settlement price of wheat drops to 2600 yuan/ton, do you want to ask Mr. Zhang for additional margin? If so, how much should I add? (2) If the settlement price of wheat in the later period rises to 3,000 yuan/ton, do you want to ask Mr. Zhang for additional margin? If so, how much should I add? [There is no handling fee in the title, so it is assumed that the handling fee is 10 yuan/hand].
(1) If the settlement price of wheat drops to 2600 yuan/ton, ask Mr. Zhang to add a deposit? If so, how much should I add?
Margin =2800 yuan/ton * 10 ton/hand * 10 hand * 10%=28000 yuan.
Handling fee = 10 yuan/hand * 10 hand = 100 yuan.
Book balance: 30,000-28,000 -6.5438+000 = 6.5438+0.900.
Money earned when a ton falls to 2,600 yuan/ton: 2,800 yuan/ton-2,600 yuan/ton =200 yuan/ton.
Money earned per hand: 200 yuan/ton * 10 ton/hand =2000 yuan/hand.
10 hand to earn money: 2000 yuan/hand * 10 hand =20000 yuan.
At this time, book funds = margin+remaining book funds+10 hand-earned funds.
= 28,000 yuan+65,438 yuan+0,900 yuan+20,000 yuan = 49,900 yuan
(2) If the settlement price of wheat in the later period rises to 3,000 yuan/ton, do you want to ask Mr. Zhang for additional margin? If so, how much should I add?
Margin =2800 yuan/ton * 10 ton/hand * 10 hand * 10%=28000 yuan.
Handling fee = 10 yuan/hand * 10 hand = 100 yuan.
Book balance: 30,000-28,000 -6.5438+000 = 6.5438+0.900.
When it rises to 3,000 yuan/ton, the loss per ton is: 2,800 yuan/ton-2,600 yuan/ton =200 yuan/ton.
Loss fund per hand: 200 yuan/ton * 10 ton/hand = 2,000 yuan/hand.
10 lot loss fund: 2000 yuan/lot * 10 lot =20000 yuan.
At this time, book funds = margin+book remaining funds-10 loss funds.
= 28,000 yuan+1900 yuan-20,000 yuan = 9,900 yuan.
But this is the result of liquidation. If the book funds need to be withdrawn from the deposit before liquidation.
Namely: 9900 yuan -28000 yuan =- 18 100 yuan.
At this time, an additional deposit of 18 100 yuan is required.
